State the slope and y-intercept of the graph of y = 1/5x – 7.

If the spinner is fair, it means that the probability of the arrow stopping on any given color is the same. Given that there are four colors on the spinner (green, blue, purple, and yellow), we can expect the arrow to stop on green 1/4 of the time. So if the spinner is spun 300 times, we would expect the arrow to stop on green 300 times * 1/4 = 75 times.

Given that the spinner has been spun once more, the table now shows that the spinner has been spun 301 times. We can estimate the probability of it landing on purple by using the number of times it has landed on purple divided by the total number of spins.

Purple: 48/301 = 0.159 or 15.9%

If the spinner is spun another 1000 times, we can expect it to land on blue 1000 * 1/4 = 250 times approximately, this is assuming the spinner is fair.

Step-by-step explanation:

The mean and standard deviation of the population is 19.8 and 0.004 respectively.

Mean:

The mean is the simple mathematical average of a set of two or more numbers. The mean of a given set of numbers can be calculated in several ways, including the arithmetic mean, which uses the sum of the numbers in the range, and the geometric mean, which takes the mean product of a set. However, all major methods of calculating simple averages produce the same approximate result most of the time.

Standard Deviation:

In statistics, standard deviation is a measure of the amount of variation or distribution of a set of values.  A low standard deviation indicates that the values ​​tend to be close to the ensemble mean (also called the expected value), while a high standard deviation indicates that the values ​​are spread over a wider range.

Given that:

E(x) = μ = 19.8

var(x) = σ²/n = 0.2/50 = 0.004

from here can say that mean = 19.8 and

standard Deviation is 0.004.

Now,

295 -298 P(Bottle x < 295) =P(Z< ) =-1.00 =.15873

Thus, there is nearly a 16% probability that just 1 randomly selected

bottle contains < 295 ml.

Answer:

Step-by-step explanation:

Given a linear function f(x) that varies at a constant rate of change 1.5 with respect to x, If x varies from x = 1.3 to x = 1.5, the to get the amount by which x change by, we will use the expression;

Δx = x₂-x₁

x₂  is the final value of x

x₁ is the initial value of x

Given x₁ = 1.3 and x₂ = 1.5

Substitute the values in the formula above;

Δx = x₂-x₁

Δx = 1.5 - 1.3

Δx = 0.2

Hence the value of x change by 0.2

The conditional probability that Eric is a high-risk driver, given that he has had no traffic accidents in the past three years, is very low. Generally, insurance companies use the number of traffic violations and/or the number of claims a driver has had within a certain time period as indicators of their riskiness.

As Eric has had no accidents or traffic violations, the probability that he is a high-risk driver is very low. However, this does not mean that the probability is zero. There are many other factors which can contribute to a driver's risk, such as age, gender, experience, and location.

If Eric is an experienced driver, who has been driving for many years with no traffic accidents, then the probability of him being a high-risk driver will be lower than the average driver. On the other hand, if Eric is a new driver, or is located in an area with a high rate of traffic accidents, then the probability of him being a high-risk driver may be higher than the average driver.

Overall, the conditional probability that Eric is a high-risk driver, given that he has had no traffic accidents in the past three years, is very low. However, this probability can change depending on other factors, such as his age, experience, and location.

Answer:

$1.68

Step-by-step explanation:

1 dozen is 12.

18 is the same as 12 + 6

6 eggs is half of 12 eggs.

Since 12 eggs cost $1.12, then 6 eggs cost half of $1.12, or $1.12/2 = $0.56.

18 = 12 + 6, so

the price of 18 eggs = the price of 12 eggs + the price of 6 eggs.

price of 18 eggs = $1.12 + $0.56 = $1.68

2.5 cm, 6.5 cm, and 6 cm are the sides of a right triangle.

The sides of a triangle are 2.5 cm, 6.5 cm, and 6 cm in length.

The Pythagorean Theorem states that The sum of the squares representing the base and height equals the square of the hypotenuse.

\((Perpendicular)^{2}+(Base)^{2}=(Hypotenuse)^{2}\)

                        \((2.5)^{2}+(6)^{2}=(6.5)^{2}\)

                            6.25 + 36 = 42.25

                                  42.25 = 42.25

The sides offered satisfy the specifications for a right triangle.

Given that it satisfies the Pythagorean theorem, a right triangle with sides of 2.5 cm, 6.5 cm, and 6 cm can be built.

Hence, 2.5 cm 6.5 cm 6 cm can be the sides of a right triangle.

Step-by-step explanation:

The angle 31 is marked for you on the figure, there is also a secondary angle marked on the other line parallel to the first. Since they are marked the same, the value of both must be 31 degrees, you can also prove this in a longer method by calculating the exact angle measures of each line. Now we simply simplify our basic equation.

Answer:

m = 1

c = 4

Step-by-step explanation:

First let's review what a slope-intercept form is.

Slope-intercept form is a specific form of linear equations. It always has y on one side and all the other terms on the other. Its structure is:

\(y = mx + c\),

where m is the slope and c is the y-intercept.

You can easily read slope (m) and intercept (c) in your equation.

\(y = mx + c\\y = x + 4\)

You can see that m in front of x is 1, because x = 1x. Multiplying with 1 perserves the number.

So:

\(m = 1\\c = 4\)

The t-test yields the probability (p value) that the null hypothesis is option (B) incorrect

The p-value in a t-test represents the probability of obtaining the observed test statistic (or one more extreme) assuming that the null hypothesis is true. The null hypothesis is typically a statement of "no effect" or "no difference" between two groups being compared in the test.

Therefore, a low p-value (generally less than 0.05) indicates that the observed data is unlikely to have occurred by chance under the null hypothesis and suggests that the null hypothesis is likely to be false.

In other words, a low p-value provides evidence against the null hypothesis and in favor of the alternative hypothesis (which typically represents the hypothesis that the researchers are interested in testing).

Thus, the p-value does not directly tell us whether the null hypothesis is correct or incorrect, but rather whether the evidence supports rejecting it or not.

Therefore, the correct option is (B) incorrect

Step-by-step explanation:

The probability that three customers will return the merchandise for exchange is 0.08192 and probability that four customers will return the merchandise for exchange is 0.01536 and the probability that none of the customers will return the merchandise for exchange is 0.262144.

Explanation: -

Part (a). The probability that three customers will return the merchandise for exchange can be calculated using the binomial probability formula: P(X=k) = C(n,k) * p^k * (1-p)^(n-k), where n is the number of trials (6 purchases), k is the desired number of successes (3 returns), and p is the probability of success (20%).

In this case, P(X=3) = C(6,3) * 0.2^3 * 0.8^3

                               = 20 * 0.008 * 0.512  

                               = 0.08192.

Part (b). The probability that four customers will return the merchandise for exchange can be calculated similarly:

P(X=4) = C(6,4) * 0.2^4 * 0.8^2

           = 15 * 0.0016 * 0.64  

           = 0.01536.

c. The probability that none of the customers will return the merchandise for exchange is calculated with k=0:

P(X=0) = C(6,0) * 0.2^0 * 0.8^6

            = 1 * 1 * 0.262144

            = 0.262144.

d. The better return policy cannot be determined solely based on these probabilities, as they only describe the likelihood of specific scenarios occurring. A better return policy would depend on factors such as customer satisfaction, cost of processing returns, and potential for increased sales due to a favorable return policy. These factors should be considered when evaluating the overall effectiveness and desirability of a return policy.

The angular area of the HST's field of view is 25 square degrees.

The field of view is the extent of the sky that the Hubble Space Telescope (HST) can observe at a given time. It is usually measured in degrees.

To calculate the angular area, we can use the formula for the area of a circle:

Area = π * (angular size/2)^2

Where π is a mathematical constant approximately equal to 3.14, and the angular size is in degrees.

Let's say the angular size of the HST's field of view is 10 degrees.

First, we divide the angular size by 2:

10 degrees / 2 = 5 degrees

Next, we square the result:

5 degrees * 5 degrees = 25 square degrees
