The admission fee at an amusement park is 1.50 for childe. and $4 for adults. on a certain day, 326 people entered the park, and the admission fee collected totaled 864.000 dollars. how many children and how many adults were admitted?

Answers

Answer 1

To solve this problem, let's assume that the number of children admitted is "x" and the number of adults admitted is "y".

Given that the admission fee for children is $1.50 and the admission fee for adults is $4, we can set up the following equations:

1.50x + 4y = 864 (equation 1)
x + y = 326 (equation 2)

To solve this system of equations, we can use the method of substitution.

From equation 2, we can express x in terms of y:
x = 326 - y

Substituting this value of x into equation 1, we get:

1.50(326 - y) + 4y = 864
489 - 1.50y + 4y = 864
2.50y = 375
y = 150

Now, substitute the value of y back into equation 2 to find x:

x + 150 = 326
x = 176

Therefore, there were 176 children and 150 adults admitted to the amusement park.

A student planning a party has $20 to spend on her favorite soft drink. it is on sale at store a for $1.29 for a 2-l bottle (plus 10-cent deposit); at store b the price of a 12-pack of 12 fl oz cans is $2.99 (plus a 5-cent deposit per can). at which store can she buy the most of her favorite soft drink for no more than $20

Answers

The student can buy the most of her favorite soft drink at store A, where she can purchase a maximum of 15 bottles within her budget.

To determine which store the student can buy the most of her favorite soft drink for no more than $20, let's compare the options at store A and store B.

At store A, the price of a 2-liter bottle is $1.29 (plus a 10-cent deposit).
To find out how many bottles the student can buy for $20, we divide $20 by the cost per bottle:

$20 / ($1.29 + $0.10) = 15.50 bottles.
However, since we cannot buy a fraction of a bottle, the student can only buy a maximum of 15 bottles.


At store B, the price of a 12-pack of 12 fl oz cans is $2.99 (plus a 5-cent deposit per can).
To find out how many 12-packs the student can buy for $20, we divide $20 by the cost per 12-pack: $20 / ($2.99 + ($0.05 * 12)) = 6.49 12-packs.
Again, since we cannot buy a fraction of a 12-pack, the student can only buy a maximum of 6 12-packs.

Therefore, the student can buy the most of her favorite soft drink at store A, where she can purchase a maximum of 15 bottles within her budget.

Solve each equation.

9+s=21

Answers

The solution to the equation is s = 12.

To solve the equation 9 + s = 21, we need to isolate the variable "s" on one side of the equation.

First, we can start by subtracting 9 from both sides of the equation to get rid of the constant term on the left side. This gives us:

s = 21 - 9

Simplifying the right side, we have:

s = 12

So the main answer to the equation is s = 12.

Start with the equation 9 + s = 21.

To isolate the variable "s", subtract 9 from both sides of the equation.

9 + s - 9 = 21 - 9

This simplifies to:

s = 12

Therefore, the solution to the equation is s = 12.

In conclusion, to solve the equation 9 + s = 21, we subtracted 9 from both sides of the equation to isolate the variable "s". The answer to the equation is s = 12.

est the null hypothesis that the mean of the population is 3 against the alternative​ hypothesis, μ≠3. use α

Answers

To test the null hypothesis that the mean of the population is 3 against the alternative hypothesis μ≠3, we can use a hypothesis test with a significance level α.

In hypothesis testing, we compare a sample statistic to a hypothesized population parameter. In this case, we want to determine if the mean of the population is significantly different from 3.

To conduct the test, we first collect a sample of data. Then, we calculate the sample mean and standard deviation.

We use these statistics to calculate the test statistic, which follows a t-distribution with (n-1) degrees of freedom, where n is the sample size.

Next, we determine the critical region based on the significance level α. For a two-tailed test, we divide α by 2 to get the critical values for both tails of the distribution.

Finally, we compare the test statistic to the critical values.

If the test statistic falls within the critical region, we reject the null hypothesis and conclude that the mean of the population is significantly different from 3.

Otherwise, if the test statistic falls outside the critical region, we fail to reject the null hypothesis.

suppose scores for a particular test have a mean of 95 and a standard deviation of 15.(a)use the empirical rule to specify the ranges into which 68%, 95%, and 99.7% of test scores fall.

Answers

The empirical rule, also known as the 68-95-99.7 rule, is used to estimate the percentage of data that falls within a certain number of standard deviations from the mean in a normal distribution.

For this question, we are given that the mean score is 95 and the standard deviation is 15.

According to the empirical rule:
Approximately 68% of the scores will fall within one standard deviation from the mean. So, in this case, the range would be from 95 - 15 to 95 + 15. This means that 68% of the scores will fall within the range of 80 to 110.

Approximately 95% of the scores will fall within two standard deviations from the mean. So, the range would be from 95 - (2 * 15) to 95 + (2 * 15). This means that 95% of the scores will fall within the range of 65 to 125.

Approximately 99.7% of the scores will fall within three standard deviations from the mean. So, the range would be from 95 - (3 * 15) to 95 + (3 * 15). This means that 99.7% of the scores will fall within the range of 50 to 140.

According to the empirical rule, 68% of the scores will fall within the range of 80 to 110, 95% of the scores will fall within the range of 65 to 125, and 99.7% of the scores will fall within the range of 50 to 140.

The empirical rule, also known as the 68-95-99.7 rule, provides a way to estimate the percentage of test scores that fall within certain ranges based on the mean and standard deviation of the scores. In this case, we have a mean of 95 and a standard deviation of 15. 68% of test scores fall within the range of 80 to 110, 95% fall within 65 to 125, and 99.7% fall within 50 to 140.



To determine the ranges into which different percentages of test scores fall, we can use the empirical rule as follows:

1. 68% of test scores: According to the empirical rule, approximately 68% of test scores fall within one standard deviation of the mean. In this case, one standard deviation is 15. Therefore, 68% of the test scores fall within the range of 95 - 15 to 95 + 15, which is 80 to 110.

2. 95% of test scores: The empirical rule states that approximately 95% of test scores fall within two standard deviations of the mean. Two standard deviations in this case is 30. So, 95% of the test scores fall within the range of 95 - 30 to 95 + 30, which is 65 to 125.

3. 99.7% of test scores: The empirical rule tells us that approximately 99.7% of test scores fall within three standard deviations of the mean. Three standard deviations in this case is 45. Thus, 99.7% of the test scores fall within the range of 95 - 45 to 95 + 45, which is 50 to 140.

In summary, based on the mean of 95 and the standard deviation of 15, we can use the empirical rule to estimate that 68% of test scores fall within the range of 80 to 110, 95% fall within 65 to 125, and 99.7% fall within 50 to 140.

one person owns seven twelfths 712 of the franchise and the second person owns one sixth16 of the franchise. what fraction of the franchise does the third person own?

Answers

The third person owns 1/4 (or three twelfths) of the franchise.

To find the fraction of the franchise owned by the third person, we need to add the fractions owned by the first and second person and subtract it from the whole.

The first person owns 7/12 of the franchise, and the second person owns 1/6 of the franchise. To add these fractions, we need to find a common denominator. The common denominator for 12 and 6 is 12.

Converting the fractions to have a denominator of 12:

First person's ownership: (7/12) = (7 * 1/12) = 7/12

Second person's ownership: (1/6) = (1 * 2/12) = 2/12

Adding the fractions: (7/12) + (2/12) = 9/12

Now, we subtract the sum from the whole to find the third person's ownership. The whole is equal to 12/12.

Third person's ownership: (12/12) - (9/12) = 3/12

Simplifying the fraction, we get: 3/12 = 1/4

Therefore, the third person owns 1/4 (or three twelfths) of the franchise.

Rihanna will walk next year if she walks for 7 hours at the same speed, we need to know her walking speed. Let's assume her walking speed is 3 miles per hour.


To find the total distance, we can multiply the speed (3 miles per hour) by the time (7 hours):
3 miles/hour × 7 hours = 21 miles
Therefore, if Rihanna walks for 7 hours at the same speed next year, she will walk 21 miles.
It's important to note that this calculation assumes Rihanna maintains a consistent walking speed throughout the entire duration of 7 hours. If her speed changes, the total distance she covers would be different.

For a criminal trial, 8 active and 4 alternate jurors are selected. Two of the alternate jurors are male and two are female. During the trial, two of the active jurors are dismissed. The judge decides to randomly select two replacement jurors from the 4 available alternates. What is the probability that both jurors selected are female? 1/12 1/6 1/2 1/4

Answers

The probability that both jurors selected are female is 1/6. To calculate the probability that both jurors selected are female,.

We need to determine the number of favorable outcomes (two female jurors selected) divided by the total number of possible outcomes.

In this scenario, there are two female alternate jurors available out of a total of four alternates. Since we need to select two jurors, we can use combinations to calculate the number of possible outcomes.

The number of possible outcomes is given by selecting 2 jurors out of 4, which can be calculated as:

C(4, 2) = 4! / (2! * (4-2)!) = 6

Therefore, there are 6 possible outcomes.

Out of these possible outcomes, we are interested in the favorable outcome where both selected jurors are female. Since there are two female alternate jurors available, we can calculate the number of favorable outcomes by selecting 2 female jurors out of 2, which is:

C(2, 2) = 2! / (2! * (2-2)!) = 1

Therefore, there is 1 favorable outcome.

Now, we can calculate the probability:

Probability = Number of favorable outcomes / Number of possible outcomes

= 1 / 6

= 1/6

Answers

The measure of this angle is equal to half the measure of the intercepted arc. ASG angles that intercept the same arc are congruent, and they are always less than or equal to 180 degrees.

When two chords intersect inside a circle, an angle is formed. The ASG angle is a type of angle formed by two chords that intersect within a circle. This angle is also known as an inscribed angle or central angle. Let's go over some important concepts related to this type of angle and explore some of its properties.
An inscribed angle is an angle that forms when two chords intersect within a circle. In particular, the angle is formed by the endpoints of the chords and a point on the circle. The measure of an inscribed angle is equal to half the measure of the intercepted arc. Therefore, we can find the measure of an ASG angle if we know the measure of the arc that it intercepts.
A central angle is another type of angle that forms when two chords intersect within a circle. This angle is formed by the endpoints of the chords and the center of the circle. The measure of a central angle is equal to the measure of the intercepted arc. This means that if we know the measure of a central angle, we can also find the measure of the intercepted arc.
One important property of ASG angles is that they are congruent if they intercept the same arc. This means that if we have two ASG angles that intercept the same arc, then the angles are equal in measure.

Another important property of ASG angles is that they are always less than or equal to 180 degrees. This is because the arc that they intercept cannot be larger than half the circumference of the circle.

Answers:

Answers

The amount of Insurance on the home as $216,000, but the amounts of coverage for the garage, loss of use, and personal property cannot be determined without additional information.

To calculate the amounts of coverage for the different components, we need to use the given replacement value and coverage percentages.

a. Amount of insurance on the home:

The amount of insurance on the home can be calculated by multiplying the replacement value by the coverage percentage for the home. In this case, the coverage percentage is 80%.

Amount of insurance on the home = Replacement value * Coverage percentage

Amount of insurance on the home = $270,000 * 80% = $216,000

b. Amount of coverage for the garage:

The amount of coverage for the garage can be calculated in a similar manner. We need to use the replacement value of the garage and the coverage percentage for the garage.

Amount of coverage for the garage = Replacement value of the garage * Coverage percentage for the garage

Since the replacement value of the garage is not given, we cannot determine the exact amount of coverage for the garage with the information provided.

c. Amount of coverage for the loss of use:

The amount of coverage for the loss of use is usually a percentage of the insurance on the home. Since the insurance on the home is $216,000, we can calculate the amount of coverage for the loss of use by multiplying this amount by the coverage percentage for loss of use. However, the percentage for loss of use is not given, so we cannot determine the exact amount of coverage for loss of use with the information provided.

d. Amount of coverage for personal property:

The amount of coverage for personal property can be calculated by multiplying the insurance on the home by the coverage percentage for personal property. Since the insurance on the home is $216,000 and the coverage percentage for personal property is not given, we cannot determine the exact amount of coverage for personal property with the information provided.

Expressing b in terms of unit vectors, we have:

    [tex]b = b_x \widehat x + b_y \widehat y[/tex]

This equation represents the vector b as a linear combination of the unit vectors [tex]\widehat x[/tex] and [tex]\widehat y[/tex], with the coefficients [tex]b_x[/tex] and [tex]b_y[/tex] representing the magnitudes of b along the x-axis and y-axis, respectively.

Therefore, the vector b can be expressed using unit vectors [tex]\widehat x[/tex] and [tex]\widehat y[/tex] by decomposing it into its x-axis and y-axis components, denoted as [tex]b_x[/tex] and [tex]b_y[/tex] respectively. This representation allows us to express b as the linear combination [tex]b_x \widehat x + b_y \widehat y[/tex], providing a concise and clear representation of the vector.

Solve the following systems of inequalities.

y
y>x²-1

Answers

The solution to the system of inequalities y and y > x² - 1 is any point above the curve of y = x² - 1, along with any real value for y.

To solve the system of inequalities, we need to find the values of x and y that satisfy both inequalities.

The first inequality, y > x² - 1, represents a shaded region above the curve of the equation y = x² - 1. This means that any point above the curve satisfies the inequality.

Now, we need to determine the points that satisfy the second inequality, y. Since there is no specific inequality given for y, we can assume that y can take any real value.

Therefore, the solution to the system of inequalities is any point above the curve of the equation y = x² - 1, combined with any real value for y. In other words, the solution is the shaded region above the curve, extending infinitely upwards.

the robotics club has 12 members. there are 3 members from each class: freshmen, sophomores, juniors, and seniors. in each of the freshman and junior classes, 1 member is an engineer and two are in cs; in each of the sophomore and senior classes, 2 are engineers and 1 is in cs. find the number of ways to have a committee of 6 members so that each class and each major is represented on the committee.

Answers

To find the number of ways to form a committee of 6 members with each class and major represented, we can consider each class and major separately.

Freshman Class:

There are 3 members in the freshman class: 1 engineer and 2 in CS. We need to choose 1 member from this class. Therefore, there are 3 options for the freshman representative.

Junior Class:

Similar to the freshman class, there are 3 members in the junior class: 1 engineer and 2 in CS. We need to choose 1 member from this class. Hence, there are 3 options for the junior representative.

Sophomore Class:

There are 3 members in the sophomore class: 2 engineers and 1 in CS. We need to choose 1 member from this class. Therefore, there are 3 options for the sophomore representative.

Senior Class:

Similarly, there are 3 members in the senior class: 2 engineers and 1 in CS. We need to choose 1 member from this class. Thus, there are 3 options for the senior representative.

Since we need to choose 6 members in total, we have 2 remaining spots to fill on the committee. From the remaining members, we can choose any 2 to fill these spots.

The number of ways to choose 2 members from the remaining 8 members (12 total members minus the 4 already selected) is given by the combination formula:

C(8, 2) = 8! / (2! * (8 - 2)!) = 8! / (2! * 6!) = (8 * 7) / (2 * 1) = 28

Therefore, the number of ways to have a committee of 6 members with each class and major represented is:

3 (freshman) * 3 (junior) * 3 (sophomore) * 3 (senior) * 28 (remaining members) = 3^4 * 28 = 3,528 ways.

A set of points has mean 10. adding a point with value 100 increases this mean from 10 to 11. how many points were in the original data set?

Answers

The original data set consisted of 89 points.

Let's assume the original data set had 'n' points.

The mean of a set of numbers is calculated by summing all the values and dividing by the number of values. In this case, the mean of the original data set is 10.

Now, if we add a point with a value of 100 to the data set, the new mean becomes 11.

To calculate the new mean, we'll use the formula:

New mean = (Sum of all values + Value of the new point) / (Number of points + 1)

Given that the new mean is 11 and the value of the new point is 100, we can write the equation as follows:

11 = (Sum of all values + 100) / (n + 1)

Next, we can simplify the equation by multiplying both sides by (n + 1):

11(n + 1) = Sum of all values + 100

Expanding the left side:

11n + 11 = Sum of all values + 100

Since the original mean was 10, the sum of all values is equal to 10n:

11n + 11 = 10n + 100

Subtracting 10n from both sides:

n + 11 = 100

Subtracting 11 from both sides:

n = 89

Therefore, the original data set consisted of 89 points.

Help please> “I had a pretty normal day,” “I have little confidence in our ability to win today,” and “That’s so random!” are statements you might use in conversation. We use a lot of everyday language to describe situations in statistics. Does the use of words that you’re already familiar with, such as normal, confidence, and random, help you understand the statistical concepts they describe? Explain why or why not.

Answers

Familiar language can provide a starting point for understanding statistical concepts, it is crucial to delve deeper into the specific definitions and principles of statistics to gain a more accurate and comprehensive understanding. This involves learning the technical vocabulary and concepts that are unique to the field of statistics.

The use of everyday language, such as the words "normal," "confidence," and "random," can provide some initial familiarity and context when describing statistical concepts. These familiar words can serve as entry points for understanding the concepts being discussed. However, it is important to note that the meaning of these words in everyday language might not align precisely with their specific definitions in statistics.

For example, when we say "I had a pretty normal day," we are generally referring to a typical or ordinary day. In statistics, the term "normal" has a specific meaning when describing a normal distribution, which is a bell-shaped probability distribution. While the everyday use of the word "normal" might evoke a sense of familiarity, it does not fully capture the technical aspects and characteristics of a normal distribution.

Similarly, when we say "I have little confidence in our ability to win today," we are expressing doubt or uncertainty. In statistics, confidence refers to the level of certainty we have in the results obtained from a sample or an estimate. However, the everyday use of the word "confidence" might not fully convey the technical definition of statistical confidence, which involves intervals and probabilities.

Likewise, the term "random" is often used in everyday language to describe something unexpected or without a specific pattern. In statistics, randomness refers to a process or outcome that cannot be predicted with certainty. While the everyday use of the word "random" may share some common aspects with its statistical definition, it does not capture the precise mathematical properties and implications of randomness in statistical analysis.

Therefore, while familiar language can provide a starting point for understanding statistical concepts, it is crucial to delve deeper into the specific definitions and principles of statistics to gain a more accurate and comprehensive understanding. This involves learning the technical vocabulary and concepts that are unique to the field of statistics.

Write a proof for the following theorem.

Supplement Theorem

Answers

The proof of the Supplement Theorem can be stated as follows: If two angles are supplementary to the same angle (or to congruent angles), then the two angles are congruent.

The Supplement Theorem states that if two angles are supplementary to the same angle (or to congruent angles), then the two angles are congruent.

To prove this theorem, we can use the following steps:

Let's assume we have two angles, angle A and angle B, which are both supplementary to angle C.

By definition, supplementary angles add up to 180 degrees.

So, we can express this as:

angle A + angle C = 180 degrees (equation 1)

angle B + angle C = 180 degrees (equation 2)

We want to prove that angle A is congruent to angle B, so we need to show that angle A = angle B.

To do that, we can subtract equation 2 from equation 1:

(angle A + angle C) - (angle B + angle C) = 180 degrees - 180 degrees

angle A - angle B = 0 degrees

angle A = angle B

Hence, we have shown that if two angles are supplementary to the same angle (or to congruent angles), then the two angles are congruent.

Therefore, the Supplement Theorem is proven.

This proof relies on the fact that if two expressions are equal to the same value, subtracting one from the other will result in zero.

In this case, subtracting the two equations shows that the difference between angle A and angle B is zero, implying that they are congruent.

Find the perimeter and area of the regular polygon circumscribed about \odot Q , with the given center and point X on the circle. Round to the nearest tenth, if necessary.

octagon A B C D E F G H ; Q(3,-1) ; X(1,-3)

Answers

The perimeter of the octagon is 16 units and the area is approximately 15.31 square units.

To find the perimeter and area of the regular octagon circumscribed about the circle with center Q(3,-1) and point X(1,-3), we need to determine the side length of the octagon.

Using the distance formula, we can find the distance between Q and X:

d(QX) = [tex]sqrt((1-3)^2 + (-3-(-1))^2)[/tex]

= [tex]sqrt((-2)^2 + (-2)^2)[/tex]

= [tex]sqrt(4 + 4)[/tex]

= [tex]sqrt(8)[/tex]

= 2sqrt(2)

Since the octagon is regular, all sides are equal. Therefore, the side length of the octagon is equal to d(QX) divided by sqrt(2):

side length =[tex](2sqrt(2)) / sqrt(2)[/tex]

= 2

The perimeter of the octagon is given by multiplying the side length by the number of sides:

perimeter = 8 * 2

= 16

To find the area of the octagon, we can use the formula:

area = [tex](2 * side length^2) * (1 + sqrt(2))[/tex]

= [tex](2 * 2^2) * (1 + sqrt(2))[/tex]

= [tex]8 * (1 + sqrt(2))[/tex]
