Minimum value is 50, maximum value is 66, median is 59, Q1 is 53.5 and Q3 is 65. Box-and-whisker plot:
Define whisker plot?A box plot, often referred to as a whisker plot, shows the distribution of a continuous variable along with details like the median, quartiles, and outliers. A set of data's variety is shown graphically in this way. The plot, often known as a five-number summary, presents five bits of information. The fundamental benefit of box whisker plots is that the overlap between the distributions of various qualities may be calculated by comparing them side by side.
You must determine the minimum value, maximum value, median, and quartiles in order to create a box-and-whisker plot of the provided data.
The base number is fifty.
The highest number is 66.
You must sort the data from smallest to largest in order to determine the median. The listed data are:
50, 51, 51, 52, 53, 53, 54, 55, 58, 58, 58, 60, 61, 62, 63, 65, 65, 66, 66
The middle value of the ordered data is the median. Finding the average of the two middle values is necessary since the data set (18 values) contains an even number of values:
(58 + 60) ÷ 2 = 59
Divide the ordered data into four equal sections before calculating the quartiles. The median of the lower half of the data set is the first quartile (Q1). The median of the data set's upper half represents the third quartile (Q3).
The data set's lower half consists of:
50, 51, 51, 52, 53, 53, 54, 55
The data set's upper half is as follows:
58, 58, 58, **60**, **61**, **62**, **63**, **65**, **65**, **66**, **66**
First quartile (Q1):
(53 + 54) ÷ 2 = **53.5**
Third quartile (Q3) comprises:
(65 + 65) ÷ 2 = **65**
With all of this knowledge at hand, you can now develop a box-and-whisker plan.

an appropriations bill passes the u.s. house of representatives with 47 more members voting in favor than against. if all 435 members of the house voted either for or against the bill, how many voted in favor and how many voted against? in favor members against mem
Answers
194 member voted against the bill whereas 241 members voted in favour of the bill.
What is bill refers to?A bill usually refers to a piece of paper money, such as a dollar bill or a euro bill.
To solve this problem, we can use algebra. Let's call the number of members who voted against the bill "x". Then, the number of members who voted in favor of the bill would be "x + 47" (since there were 47 more members voting in favor than against).
We know that the total number of members who voted (either for or against) was 435. So, we can write an equation:
x + (x + 47) = 435
Simplifying this equation, we get:
2x + 47 = 435
Subtracting 47 from both sides:
2x = 388
Dividing both sides by 2:
x = 194
So, 194 members voted against the bill, and the number of members who voted in favor would be:
x + 47 = 194 + 47 = 241
Therefore, 241 members voted in favor of the bill.

a rectangular poster is to contain 392 square inches of print. the margins at the top and bottom of the poster are to be 2 inches, and the margins on the left and right are to be 1 inch. what should the dimensions of the poster be so that the least amount of poster is used?
Answers
The dimensions of the poster be so that the least amount of poster is used are A = 6L + 4W + 412.
Let the length and width of the printable area of the poster be L and W, respectively. Then, the total dimensions of the poster can be expressed as L + 2(2) and W + 2(1), since there are 2-inch margins at the top and bottom, and 1-inch margins on the left and right.
We know that the area of the printable area of the poster is 392 square inches. Therefore, we can write the equation: LW = 392
We want to minimize the total area of the poster, which is given by:
A = (L + 2(2))(W + 2(1)) = (L + 4)(W + 2)
Expanding this expression, we get:
A = LW + 2L + 4W + 8
Substituting the equation for LW, we get:
A = 392 + 2L + 4W + 8
Simplifying, we get:
A = 2L + 4W + 400
To minimize this expression, we can take the partial derivatives with respect to L and W and set them equal to zero:
[tex]∂A/∂L = 2 = 0 => L = 0[/tex]
[tex]
∂A/∂W = 4 = 0 => W = -100[/tex]
These values do not make sense in the context of the problem. Therefore, we can conclude that the dimensions of the poster that minimize the amount of poster used cannot be found using this method.
Instead, we can use the fact that the printable area of the poster has a fixed area of 392 square inches, and that the margins have fixed dimensions. We can express the area of the poster as:
A = (L + 4)(W + 2) = LW + 4L + 2W + 8
Substituting the equation for LW, we get:
A = 392 + 4L + 2W + 8
Simplifying, we get:
A = 4L + 2W + 400
To minimize this expression, we can again take the partial derivatives with respect to L and W and set them equal to zero:
[tex]∂A/∂L = 4 = 0 => L = 0[/tex]
[tex]∂A/∂W = 2 = 0 => W = -200[/tex]
These values do not make sense in the context of the problem. Therefore, we can conclude that the dimensions of the poster that minimize the amount of poster used cannot be found using this method either.
We can try a different approach. We can use the fact that the printable area of the poster has a fixed area of 392 square inches, and that the total area of the poster is given by:
A = (L + 4)(W + 2) + 2(L + 4) + 2(W + 2)
Expanding this expression, we get:
A = LW + 6L + 4W + 20
Substituting the equation for LW, we get:
A = 392 + 6L + 4W + 20
Simplifying, we get: A = 6L + 4W + 412
To minimize this expression, we can take the partial derivatives with respect to L and W and set them equal to zero:
[tex]∂A/∂L = 6 = 0 => L = -2/3[/tex]
[tex]∂A/∂W = 4 = 0 => W = -3/2[/tex]

Answers
The expression that represents the total amount that Julian paid at the register in terms of x is 0.84x.
What is Percentage?
Percentage is a way of expressing a proportion or fraction as a quantity out of 100. The word "percent" means "per hundred," so percentages are often denoted by the symbol %, which represents one part in a hundred.
The first step is to find the discounted price after the 20% discount. This can be found by multiplying the original price by (1 - 0.2), which represents a 20% reduction.
Discounted price = x - 0.2x = 0.8x
Next, a 4% tax is added to the discounted price. This can be found by multiplying the discounted price by (1 + 0.04), which represents a 4% increase.
Total amount paid = (0.8x) * (1 + 0.04) = 0.84x

if p is a prime number and a is a positive inte- ger, how many distinct positive divisors does pa have?
Answers
If p is a prime number and a is a positive integer, then pa has (a+1) distinct positive divisors.
A prime number is a positive integer greater than 1, which is divisible only by 1 and itself. Divisors are the numbers that evenly divide a given number.
For a prime number p raised to the power of a (p^a), the number of distinct positive divisors can be found using the following formula:
Number of divisors = (a + 1)
This is because each power of p from 0 to a can divide p^a without any remainder, giving us a total of a + 1 distinct divisors. These divisors are:
1, p, p^2, p^3, ..., p^(a-1), p^a
For example, if p = 2 (a prime number) and a = 3 (a positive integer), then the number of distinct positive divisors for 2^3 (which is 8) would be:
Number of divisors = (3 + 1) = 4
The divisors for 2^3 (8) are 1, 2, 4, and 8.

10
A.) 150 calories per cm of diameter
B.) 33 calories per cm of diameter
C.) 65calories per cm of diameter
D.) 215 calories per cm of diameter
Answers
Answer:
To find the average rate of change of the function f(x) = 1.5x² over the interval [10, 11], we need to calculate the change in f(x) over the interval, and divide by the change in x.
The change in f(x) over the interval [10, 11] is:
f(11) - f(10) = (1.511^2) - (1.510^2) = 165 - 150 = 15
The change in x over the interval [10, 11] is:
11 - 10 = 1
Therefore, the average rate of change of the function over the interval [10, 11] is:
(15/1) = 15
This means that for every 1 cm increase in diameter (i.e., for every 1 unit increase in x), the number of calories in the pancake increases by an average of 15 calories per cm of diameter.
Therefore, the answer is (A) 150 calories per cm of diameter.

How to calculate the probability?Assuming that each prize is drawn independently of the others and that any person can win any of the prizes, we can find the probability that Abby, Barry, and Sylvia win the first, second, and third prizes, respectively, by using the multiplication principle of probability.
The probability of Abby winning the first prize is 1/200, since there are 200 people in the contest and only one of them can win the first prize. Similarly, the probability of Barry winning the second prize is also 1/200, and the probability of Sylvia winning the third prize is also 1/200.
Since winning more than one prize is allowed, the probability of all three of these events occurring simultaneously is simply the product of their individual probabilities:
P(Abby wins 1st prize AND Barry wins 2nd prize AND Sylvia wins 3rd prize) = (1/200) * (1/200) * (1/200) = 1/8,000,000

armer needs a fenced-in 1 square kilometer rectangular region. on one of the four sides, she decides to use fencing that costs three times as much as the fencing on the other three sides. what dimensions will minimize the cost of the fence?
Answers
The dimensions will minimize the cost of fence 3555C, armer needs a fenced-in 1 square kilometer rectangular region.
Let the length of the rectangular region be 'l' and the width be 'w'. The area of the rectangular region is given by:
A = lw = 1 sq. km = 1000 x 1000 sq. m
We need to minimize the cost of the fence, which consists of three sides with fencing of cost C and one side with fencing of cost 3C. The total cost of the fence is given by:
Cost = 3Cw + C(2l + w) = 2C(l + w) + Cw
To minimize the cost, we take the derivative of the cost function with respect to w and set it equal to zero:
dCost/dw = 2C - C[tex]w^{(-2)}[/tex]l = 0
Solving for l, we get:
l = 2w
Substituting this value of l in the area equation, we get:
w(2w) = 1000000
2w² = 1000000
w² = 500000
w = √(500000) m = 707.1 m
So, the width of the rectangular region is 707.1 m and the length is 2w = 2 x 707.1 m = 1414.2 m.
Therefore, the dimensions that minimize the cost of the fence are 707.1 m x 1414.2 m and the minimum cost of the fence is:
Cost = 2C(l + w) + Cw = 2C(1414.2 + 707.1) + C(707.1) = 3555C.

in general, we have 12 marbles.
let's change the problem description into picking a marbles that is not blue.
we have 6 blue marbles.
the chance to pick a blue marble is therefore 6/12 = 1/2.
and the probability to not pick a blue marbles is 1 - 1/2 = 1/2.
so, in 24 pulls, we expect 24× 1/2 = 12 times to get a marble that is not blue.
or change it to "not green" marbles.
5 green marbles.
the probability to pick a green marble is 5/12.
the probabilty to not pick a green marble = 1 - 5/12 = 7/12.
in 24 pulls we expect 24 × 7/12 = 14 times to get a marble that is not green.
it change it to "not purple" marbles.
1 purple marble.
the probability to pick a purple marble is 1/12.
the probabilty to not pick a purple marble = 1 - 1/12 = 11/12.
in 24 pulls we expect 24 × 11/12 = 22 times to get a marble that is not purple.
State the amplitude, period, phase shift, and vertical shift of the function kt=cos2pit/3

Answer:
The given function is k(t) = cos(2πt/3).
The general form of a cosine function is A*cos(Bx - C) + D, where:
A is the amplitudeB is the frequency (which is related to the period)C is the phase shiftD is the vertical shiftComparing this form to the given function, we can see that:
The amplitude of k(t) is A = 1, since the maximum value of the cosine function is 1 and the minimum value is -1.The frequency of k(t) is B = 2π/3, since the argument of the cosine function is 2πt/3. The frequency is related to the period T by the formula T = 2π/B. Therefore, the period of k(t) is T = 3.The phase shift of k(t) is C = 0, since there is no horizontal shift in the argument of the cosine function.The vertical shift of k(t) is D = 0, since the average value of the cosine function over one period is zero.Therefore, the amplitude of k(t) is 1, the period of k(t) is 3, the phase shift of k(t) is 0, and the vertical shift of k(t) is 0.

A = P(1 + r/n)^(nt)
where A is the accumulated amount, P is the principal (initial amount invested), r is the interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the time (in years) for which the money is invested.
Let's use this formula to find the initial principal, P
7,365 = P(1 + 0.08/12)^(12*number of years)
We can solve for P by dividing both sides by the right-hand side and simplifying,
P = 7,365 / (1 + 0.08/12)^(12*number of years)
Now we know that the initial principal was P, and it earned R2 000.00 in interest during the first period. Therefore, the accumulated amount at the end of the first period was,
A1 = P + R2 000.00
A1 = P + P(0.08/12)
A1 = P(1 + 0.08/12)
Now, we want to find the accumulated amount at the end of the second period, which is one year longer than the first period. We can use the same formula as before, but with a time of (number of years + 1),
A2 = P(1 + 0.08/12)^(12*(number of years + 1))
We know that A1 = P(1 + 0.08/12), so we can substitute this into the formula for A2,
A2 = A1(1 + 0.08/12)^(12)
A2 = (P(1 + 0.08/12))(1 + 0.08/12)^(12)
A2 = P(1 + 0.08/12)^13
Now we can substitute the expression we found for P earlier,
A2 = (7,365 / (1 + 0.08/12)^(12*number of years))(1 + 0.08/12)^13
A2 = 7,365(1 + 0.08/12)^(12*number of years + 13)
A2 = 7,365(1.007)^((12*number of years) + 13)
A2 = 8,829.71

consider straight wires of equal lengths with their ends soldered together to form the edges of a cube. either silver or copper wire can be used for each edge. how many different ways can the cube be constructed?
Answers
The number of valid ways to construct the cube is [tex]4096 - 48 = 4048[/tex]
Each corner of the cube is formed by three wires coming together. Since the wires are soldered together at the ends, each corner must have either 3 silver wires or 3 copper wires coming together.
There are two choices for each wire: it can be silver or copper. Since there are 12 edges in a cube, there are 2 choices for each edge, giving a total of [tex]2^12 = 4096[/tex] possible arrangements of the edges.
However, not all of these arrangements are valid. We must eliminate the arrangements where at least one corner has two silver wires and one copper wire
There are 8 corners in a cube, and for each corner, there are 3 ways to choose which wire is different from the other two. Once we choose which wire is different, there are 2 choices for its color (silver or copper). Thus, there are [tex]8 x 3 x 2 = 48[/tex] invalid arrangements.

Solve the Simple Interest
Ruby contributes 12% of the total cost of her individual health care. This is a $57.50 deduction from each of her biweekly paychecks. What is the total value of her individual coverage for the year? Find its employer share.
Answers
Using simple interest we know the Total value of annual health coverage is $9000.
What is simple interest?Borrowers must pay lenders simple interest as a fee in exchange for a loan.
Compound interest is excluded from the calculation and just the original principal is used.
Simple interest applies to all loans, not just specific ones.
Additionally, it refers to the kind of interest that banks give their customers on their savings accounts.
So, complete yearly health coverage calculation
Let x be the total annual healthcare budget.
Ruth contributes 18% of the entire cost of healthcare, or $67.50 for two weeks. (ie 15 days)
So, total paid for one month = 67.5 x 2 = 135
The total amount paid for the entire year is 135 x 12 = 1620.
She foots 18% of the overall annual health care costs, as was already established.
Then,
18% x = 1620
18 x / 100 = 1620
x = (1620 x 100) / 18
= $9000
Therefore, using simple interest we know the Total value of annual health coverage is $9000.

You are helping with some repairs at home. You drop a hammer and it hits the floor at a speed of 4 feet per second. If the acceleration due to gravity (g) is 32 feet/second 2, how far above the ground (h) was the hammer when you dropped it? Use the formula:
Answers
Step-by-step explanation:
vf = vo + at vo = 0 in this case ( you dropped it from 'at rest')
4 f/s = 32 t
t = 1/8 s
df = do + vot + 1/2 at^2 df = final position = 0 ft (on the ground)
0 = do + 0 + 1/2 (-32)(1/8)^2
solve for do = 1/4 foot
An angle measures 37.6° more than the measure of its complementary angle. What is the measure of each angle?
Answers
The pair of required complementary angles are 26.2° and 63.8° respectively.
What are complementary angles?Two angles are said to be supplementary angles because they combine to generate a linear angle when their sum is 180 degrees.
When two angles add up to 90 degrees, however, they are said to be complimentary angles and together they make a right angle.
If the total of two angles is 90o (ninety degrees), then the angles are complementary.
A 30-angle and a 60-angle, for instance, are two complementary angles.
So, to find the 2 angles which are complementary:
x + x + 37.6 = 90
Now, solve it as follows:
x + x + 37.6 = 90
2x = 90 - 37.6
2x = 52.4
x = 52.4/2
x = 26.2
Now, x = 26.2 and the second angle x + 37.6 is = 26.2 + 37.6 = 63.8°.
Therefore, the pair of required complementary angles are 26.2° and 63.8° respectively.

You would first set up your problem like it is in the picture. Then, bring 2 down. Next, multiply 2 by -3 (for future problems, you would multiply the number you brought down by whatever number is on the side). -3 × 2 = -6, so you would put that under 3 (as shown in the picture). Now, add 3 and -6 (which = -3). Repeat this step each time.

Write a sine function that has an amplitude of 3, a midline of y =2 and a period of 1
Answers
the sine function that meets the given conditions is:
[tex]y(t) = 3 \times sin ((2\pi / 1200) \times t) + 2[/tex]
Function with the given characteristics.
The terms and their definitions we need to consider:
Amplitude:
The maximum displacement from the midline (in this case, 3)
Midline:
The horizontal line that passes through the center of the wave (y = 2)
Period:
The length of one complete cycle of the wave (1200)
Now, let's write the sine function:
[tex]y(t) = A \times sin (B \times t) + C[/tex]
Where:
y(t) is the sine function with respect to time (t)
A is the amplitude (3)
B is the frequency (to be determined)
C is the midline (2)
First, we need to find the frequency (B).
The period and frequency are related by the following formula:
[tex]Period = 2\pi / B[/tex]
In this case, the period is 1200:
[tex]1200 = 2\pi / B[/tex]
Now, solve for B:
[tex]B = 2\pi / 1200[/tex]
Now, we can plug in the amplitude (A), frequency (B), and midline (C) into our sine function:
[tex]y(t) = 3 \times sin((2\pi / 1200) \times t) + 2[/tex]
