3.12 speeding on the i-5, part i: the distribution of passenger vehicle speeds traveling on the interstate 5 freeway (i-5) in california is nearly normal with a mean of 72.6 miles/hour and a standard deviation of 4.78 miles/hour. (a) what percent of passenger vehicles travel slower than 80 miles/hour?
Approximately 68.3% of passenger vehicles travel slower than 80 miles/hour.
1. suppose we know that the average weight of coyotes is 14.5kg with a standard deviation of 4kg. what is the probability of trapping a coyote that is 17kg or larger?
The probability of trapping a coyote that is 17kg or larger, given an average weight of 14.5kg and a standard deviation of 4kg is approximately 0.2743 or 27.43%.
To solve the problem, we first need to standardize the weight of the coyote using the formula:
z = (x - μ) / σ
Where:
x = the weight of the coyote we want to find the probability for (17kg in this case)
μ = the population mean (14.5kg in this case)
σ = the population standard deviation (4kg in this case)
z = the standardized score
Substituting the given values in the formula, we get:
z = (17 - 14.5) / 4
z = 0.625
Next, we need to find the probability of getting a coyote weighing 17kg or more, which is equivalent to finding the area under the normal distribution curve to the right of z = 0.625. We can use a standard normal distribution table or a calculator to find this probability.
Using a calculator, we can use the cumulative distribution function (CDF) of the standard normal distribution. The CDF gives the area under the curve to the left of a specified z-score. Since we want the area to the right of z = 0.625, we can subtract the CDF from 1 to get the area to the right.
Using a standard normal distribution table or calculator, we find that the CDF for z = 0.625 is approximately 0.734. Therefore, the area to the right of z = 0.625 is 1 - 0.734 = 0.266 or 26.6%.
Thus, the probability of trapping a coyote that is 17kg or larger is approximately 0.266 or 26.6%.

Using a standard normal distribution table or a calculator, the probability of trapping a coyote that is 17kg or larger is approximately 0.266 or 26.6%.
What exactly is a standard normal distribution?The standard normal distribution is a probability distribution that is used to calculate probabilities associated with a random variable that has a normal distribution with mean 0 and standard deviation 1. Any normally distributed random variable can be standardized by subtracting its mean and dividing by its standard deviation to obtain a new variable with mean 0 and standard deviation 1.
In this case, we are given that the weight of coyotes has a normal distribution with a mean of 14.5kg and a standard deviation of 4kg. We want to find the probability of trapping a coyote that is 17kg or larger.
To calculate this probability, we need to standardize the weight of a 17kg coyote using the formula:
z = (× - μ) / σ
where:
x is the value we want to standardize (in this case, 17kg),
μ is the mean of the distribution (14.5kg),
σ is the standard deviation of the distribution (4kg).
Substituting the values we have:
[tex]z =\frac{(17 - 14.5)}{4} = 0.625[/tex]
This value of 0.625 is the z-score for a coyote weighing 17kg. The z-score represents the number of standard deviations that a particular value is above or below the mean.
Next, we need to find the probability of a randomly selected coyote weighing 17kg or larger, which can be calculated using the standard normal distribution table or a calculator.
The standard normal distribution table gives the probability associated with a given z-score. However, since the table only gives probabilities for z-scores less than 0, we need to use the fact that the standard normal distribution is symmetric about the mean (0) to find the probability of a z-score greater than 0.625.
Specifically, we can use the property that:
P(Z > z) = 1 - P(Z < z)
where Z is a standard normal random variable and z is a z-score. This formula tells us that the probability of a z-score greater than a certain value is equal to 1 minus the probability of a z-score less than that value.
Using this formula, we can calculate:
P(Z > 0.625) = 1 - P(Z < 0.625)
We can look up the value of P(Z < 0.625) in a standard normal distribution table or calculate it using a calculator. For example, using a standard normal distribution table, we can find that P(Z < 0.625) = 0.734.
Substituting this value into the formula, we get:
P(Z > 0.625) = 1 - 0.734 = 0.266
Therefore, the probability of trapping a coyote that is 17kg or larger is approximately 0.266 or 26.6%.

What is descriptive statistics?Descriptive statistics is a branch of statistics that deals with the collection, organization, analysis, and interpretation of numerical data. It involves using various statistical measures to describe and summarize the characteristics of a set of data. Descriptive statistics helps to make sense of large amounts of data by presenting it in a more meaningful and understandable way. Commonly used measures of central tendency in descriptive statistics include mean, median, and mode, while measures of dispersion include range, variance, and standard deviation. Descriptive statistics is widely used in various fields, such as business, medicine, economics, psychology, and social sciences, to name a few.
Median, because Sunny Town is skewed.
The skewness of the histogram for Sunny Town indicates that the data is not symmetrically distributed, and therefore the median would be a better measure of central tendency to compare the locations.

d. Amanda
is considering changing her regimen by running two miles the first week and then running
additional two miles each subsequent week. Write a sequence for the number of miles that Amanda
would run the first 10 weeks of her training if she followed the new regimen. Explain your reasoning.
Answer: If Amanda runs two miles the first week and then adds two miles each subsequent week, we can create a sequence using arithmetic progression. The common difference between each term in the sequence is two, and the first term is two.
Using the formula for the nth term of an arithmetic progression, we can find the number of miles Amanda would run in the first 10 weeks of her training:
an = a1 + (n-1)d
where:
an = the nth term of the sequence
a1 = the first term of the sequence (2 miles in the first week)
n = the number of terms (up to 10 weeks)
d = the common difference between each term (2 miles per week)
So for n = 1 to 10, we have:
a1 = 2
d = 2
n = 1: a1 + (n-1)d = 2 + (1-1)2 = 2
n = 2: a1 + (n-1)d = 2 + (2-1)2 = 4
n = 3: a1 + (n-1)d = 2 + (3-1)2 = 6
n = 4: a1 + (n-1)d = 2 + (4-1)2 = 8
n = 5: a1 + (n-1)d = 2 + (5-1)2 = 10
n = 6: a1 + (n-1)d = 2 + (6-1)2 = 12
n = 7: a1 + (n-1)d = 2 + (7-1)2 = 14
n = 8: a1 + (n-1)d = 2 + (8-1)2 = 16
n = 9: a1 + (n-1)d = 2 + (9-1)2 = 18
n = 10: a1 + (n-1)d = 2 + (10-1)2 = 20
Therefore, Amanda would run 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20 miles in the first 10 weeks of her training if she followed the new regimen.

A jacket at the store is being offered at a 30% discount. If the original price of the jacket is x, which answer choice shows an expression that represents the discounted price of the jacket?
The expression that represents the discounted price of the jacket is 0.7x. This means that the discounted price is 70% of the original price, or equivalently, that the discount reduces the price of the jacket by 30%.
What is original price?
In order to determine the sales price, the value of the discount would be subtracted from the original price.
When an item is offered at a discount, the discounted price is usually calculated by subtracting the discount from the original price. In this case, since the discount is 30%, we can find the amount of the discount by multiplying the original price x by 0.3. This gives us 0.3x, which is the amount of money that is being discounted from the original price. To find the discounted price, we subtract this amount from the original price, which gives us:
x - 0.3x = 0.7x
So, the expression that represents the discounted price of the jacket is 0.7x. This means that the discounted price is 70% of the original price, or equivalently, that the discount reduces the price of the jacket by 30%.

The probability that all four chosen balls are red is 14/6075.
What is probability?Probability is a way to gauge how likely or unlikely something is to happen. It is a number between 0 and 1, where 0 denotes an improbable event and 1 denotes an inevitable one.
According to question:Let's first find the probability of choosing two red balls from each of the two urns separately and then multiply the results.
The probability of choosing two red balls from urn 1 is:
P(2 red balls from urn 1) = (7/10) * (6/9) = 7/15
Similarly, the probability of choosing two red balls from urn 2 is:
P(2 red balls from urn 2) = (2/10) * (1/9) = 1/45
And the probability of choosing two red balls from urn 3 is:
P(2 red balls from urn 3) = (5/10) * (4/9) = 2/9
Now, we need to find the probability of choosing two urns out of three, and since the order in which we choose the urns does not matter, we can use combinations:
Number of ways to choose two urns out of three = C(3, 2) = 3
Therefore, the probability of choosing two urns out of three is 3/3 = 1.
Finally, we need to multiply the probability of choosing two red balls from each of the two urns and the probability of choosing two urns out of three:
P(all four balls are red) = P(2 red balls from urn 1) * P(2 red balls from urn 2) * P(2 red balls from urn 3) * P(choose two urns out of three)
= (7/15) * (1/45) * (2/9) * 1
= 14/6075
Therefore, the probability that all four chosen balls are red is 14/6075.

The system of equation has no solution (option b).
Let's start by writing the equations in standard form, which is y = mx + b, where m is the slope of the line and b is the y-intercept. We have:
y = -5x - 1
y = -5x + 7
Both equations have the same slope of -5, which means they are parallel lines. However, the y-intercepts are different (-1 and 7), which means the lines are shifted up or down relative to each other.
We can also confirm this algebraically by subtracting one equation from the other:
y = -5x + 7 - (-5x - 1)
y = -5x + 5

Answer:
1. With the height and base of a triangle given, we can use the Pythagorean Theorem to find the length of the hypotenuse (the third side) of the right triangle.
Given:
Height (a) = 6
Base (b) = 8
We can plug these values into the Pythagorean Theorem formula:
a^2 + b^2 = c^2
Substituting the values:
6^2 + 8^2 = c^2
Simplifying:
36 + 64 = c^2
100 = c^2
Now, we can take the square root of both sides to solve for c:
√100 = √c^2
10 = c
So, the length of the hypotenuse (c) of the right triangle is 10 units.
2.
Given:
Base (b) = 8
One side (a or c) = 12
We can use the Pythagorean Theorem to find the length of the remaining side (either a or c) of the right triangle.
The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Using the formula:
a^2 + b^2 = c^2
Substituting the values:
a^2 + 8^2 = 12^2
Simplifying:
a^2 + 64 = 144
Next, we can isolate a^2 by subtracting 64 from both sides of the equation:
a^2 = 144 - 64
a^2 = 80
Finally, we can take the square root of both sides to solve for a:
√(a^2) = √80
a ≈ 8.94 (rounded to two decimal places)
So, the length of the remaining side (either a or c) of the right triangle is approximately 8.94 units. Please note that depending on the context of the problem, you may need to use the positive square root value for a or c, depending on which side is relevant in the specific scenario.
Answer:
X = 10^2
Y = /80
Step-by-step explanation:
Pythagorean theorem = A^2 +B^2= C^2
Fist triangle
6^2+8^2
36 + 64= 100
/100 = 10^2
X= 10^2
Second triangle
Pythagorean theorem = C^2 - A^2= B^2
12^2 - 8^2
144 - 64= 80
/80 = /80
X = /80

which measures of center and variability would be most appropriate to describe the given distribution?
The choice of measures of center and variability depends on the shape and characteristics of the distribution. If the distribution is skewed or has outliers, then the median and IQR would be more appropriate measures of center and variability, respectively.
What is median?The median is a measure of central tendency that represents the middle value in a dataset when the data is arranged in order of magnitude. Specifically, it is the value that separates the data set into two equal halves. In other words, half of the values in the dataset are greater than the median, and the other half are less than the median.
To calculate the median, you first need to arrange the data in order from lowest to highest (or highest to lowest).
The value that divides the data set into two equal portions is called the median. It is a robust measure of center, meaning that it is not affected by extreme values or outliers. The IQR is the range of values that contains the middle 50% of the data, and it is also a robust measure of variability.

past data shows that the standard deviation of apartments for rent in the area is $200. suppose we want a 98% confidence interval with margin of error of 50. what sample size do we need?
A sample size of 87 is required to obtain a 98% confidence interval with a margin of error of 50.
How to calculate sample size?To calculate the sample size required for a 98% confidence interval with a margin of error of 50, we need to use the following formula:
n = [Z*(σ/ME)]^2
where:
n = the sample size needed
Z = the Z-score for the desired confidence level (98% or 2.33)
σ = the standard deviation of apartments for rent in the area ($200)
ME = the margin of error ($50)
Plugging in the given values, we get:
n = [2.33*(200/50)]^2
n = [9.32]^2
n ≈ 86.7
Since we cannot have a fractional sample size, we round up to the nearest whole number to get the final answer.
Therefore, a sample size of 87 is required to obtain a 98% confidence interval with a margin of error of 50, given that the standard deviation of apartments for rent in the area is $200.

a motor boat traveling at 18 miles per hour traveled the length of a lake in one-quarter of an hour less time than it took when traveling at 12 miles per hour. what was the length in miles of the lake?
The length of the lake in miles for the given situation of travelling motor boat is equal to 9 miles.
Let us consider the length of the lake be d in miles.
Number of miles motor boat travelled per hour = 18 miles
When the motor boat travels at 18 miles per hour,
The time it takes to travel the length of the lake is,
t₁ = d/18
When the motor boat travels at 12 miles per hour,
The time it takes to travel the length of the lake is,
t₂ = d/12
Time it takes to travel the length of the lake at 18 miles per hour
= one-quarter of an hour less than the time it takes at 12 miles per hour,
⇒ t₁ = t₂ - 1/4
Substituting the expressions for t₁ and t₂ from above, we get,
⇒ d/18 = d/12 - 1/4
Simplify this equation by multiplying both sides by the least common multiple of the denominators,
least common multiple = 36
⇒ 2d = 3d - 9

The amount y (in dollars) of money in your
savings account after x months is represented by the equation y = 12.5x+100.
A Graph the linear equation
b. How many months will it take to save a total of $237.50
A. we can plot another point at (1, 112.5), and continue this pattern to draw the line. Linear equation graph
B. It will take 11 months to save a total of $237.50.
What is a graph?
In computer science and mathematics, a graph is a collection of vertices (also known as nodes or points) connected by edges (also known as links or lines).
a. To graph the linear equation y = 12.5x+100, we can use the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.
Comparing y = 12.5x+100 to y = mx + b, we can see that the slope is 12.5 and the y-intercept is 100.
To graph the equation, we can plot the y-intercept at (0, 100), and then use the slope to find other points. The slope of 12.5 means that for every increase of 1 in x (i.e. for every month), y increases by 12.5. So, we can plot another point at (1, 112.5), and continue this pattern to draw the line.
linear equation graph
b. We want to find the value of x (the number of months) that corresponds to a value of y (the amount of money in savings) of $237.50.
We can set y = 237.50 in the equation y = 12.5x+100, and solve for x:
237.50 = 12.5x+100
Subtracting 100 from both sides, we get:
137.50 = 12.5x
Dividing both sides by 12.5, we get:
x = 11
So, it will take 11 months to save a total of $237.50.

the ratio of the amount of ink used in a table or chart that is necessary to convey information to the total amount of ink used in the table and chart is known as data-ink ratio. using additional ink that is not necessary to convey information has what effect on the data-ink ratio?
Using additional ink that is not necessary to convey information reduces the data-ink ratio, which should be maximized in order to effectively convey essential information in a table or chart.
Using additional ink that is not necessary to convey information reduces the data-ink ratio. The goal of maximizing the data-ink ratio is to ensure that the ink used in the visual representation of data is used only to convey the necessary information, without cluttering or distracting from the main message.
When unnecessary ink is used, it increases the amount of ink used overall, reducing the proportion of ink used for conveying information, and thus reducing the data-ink ratio. Therefore, to maximize the effectiveness of a table or chart, it's important to minimize the use of non-data ink and focus on the essential information.

What is Decimal?A decimal is a way of representing numbers using a base-10 positional notation system, where each digit represents a power of 10. It is written as a whole number followed by a decimal point and a series of digits representing fractions of 1.
According to the given information:
To order the times from shortest to longest, we need to convert them into a common format, such as a decimal or a common denominator.
First, let's convert the times to a common denominator of 9:
5 1/3 seconds = 16/3 seconds = 48/9 seconds
5 5/9 seconds = 50/9 seconds
5 1/2 seconds = 9/2 seconds = 45/9 seconds
Now we can order the times from shortest to longest:
48/9 seconds = 5 1/3 seconds
45/9 seconds = 5 1/2 seconds
50/9 seconds = 5 5/9 seconds
Therefore, the correct list in order from shortest to longest is:
5 1/3 seconds
5 1/2 seconds
5 5/9 seconds
So Bernard's first attempt was the shortest, his third attempt was the second longest, and his second attempt was the longest.

What is the loan factor is Magada decides to pay her monthly repayments over a 25 year period with an interest of 10. 75%
Magada's loan factor is approximately 0.006367. This means that for every $1 borrowed, Magada will have to pay approximately $0.006367 per month for the next 25 years to repay the loan with an interest rate of 10.75%.
To calculate the loan factor, we first need to calculate the monthly interest rate and the total number of monthly payments.
Monthly interest rate = Annual interest rate / 12
= 10.75% / 12
= 0.8958%
Monthly payments = Number of years * 12
= 25 * 12
= 300
Now, we can use loan factor formula, which is:
Loan factor = [monthly interest rate * (1 + monthly interest rate)^n] / [(1 + monthly interest rate)^n - 1]
Substituting the values, we get:
Loan factor = [0.008958 * (1 + 0.008958)^300] / [(1 + 0.008958)^300 - 1]
= 0.006367
