the travel time for a college student traveling between her home and her college is uniformly distributed between 40 and 90 minutes. the probability that she will finish her trip in 60 minutes or less is
The probability that the student will finish her trip in 60 minutes or less is 0.4
To find the probability that the student will finish her trip in 60 minutes or less, we need to find the proportion of the total area under the uniform distribution curve that lies to the left of 60 minutes.
Since the travel time is uniformly distributed between 40 and 90 minutes, the probability density function is
f(x) = 1/(90-40) = 1/50, for 40 ≤ x ≤ 90
The probability of finishing the trip in 60 minutes or less is therefore
P(X ≤ 60) = ∫[40, 60] f(x) dx
= (60-40)/50

Hi so you have to do grid for the equation
if the odds on a bet are 41:1 against, what is the probability of winning? express your answer as a fraction.
The probability of winning is 1/42 expressed as a fraction.
Given that the odds on a bet are 41:1 against, we are to find the probability of winning.
We know that odds against = (Number of unfavorable outcomes) : (Number of favorable outcomes).
Thus, odds against = 41:1. This implies that the number of unfavorable outcomes is 41 and the number of favorable outcomes is 1.Probability of winning is given by the formula P(winning) = Number of favorable outcomes / Total number of possible outcomes. In this case, the total number of possible outcomes is the sum of the number of favorable and unfavorable outcomes.
Number of favorable outcomes = 1 and Number of unfavorable outcomes = 41
Therefore, the total number of possible outcomes = 1 + 41 = 42
Thus, P(winning) = Number of favorable outcomes / Total number of possible outcomes
P(winning) = 1 / 42
Therefore, the probability of winning is 1/42 expressed as a fraction.

Consider the following hypothesis test. H0: μ ≤ 50 Ha: μ > 50 A sample of 60 is used and the population standard deviation is 8. Use the critical value approach to state your conclusion for each of the following sample results. Use α = 0. 5. (Round your answers to two decimal places. ) (a) x = 52. 7 Find the value of the test statistic. State the critical values for the rejection rule. (If the test is one-tailed, enter NONE for the unused tail. ) test statistic ≤ test statistic ≥ (b) x = 51 what is the test statistics? c) x = 51. 8 what is the test statistics?
the test statistic (1.58) is greater than the critical value for a right-tailed test with α = 0.05.
To test the hypothesis H0: μ ≤ 50 vs Ha: μ > 50 at a significance level of α = 0.05, we can use a one-tailed z-test.
a) For the sample result x = 52.7, the test statistic is given by:
z = (x - μ) / (σ / [tex]\sqrt{n}[/tex]) = (52.7 - 50) / (8 / [tex]\sqrt{60}[/tex] ) = 2.38
To find the critical values for the rejection rule, we need to determine the z-value that corresponds to a right-tail probability of 0.05. Since we are using a one-tailed test, we can look up the z-value in the standard normal distribution table. The critical value for a right-tailed test with α = 0.05 is:
zα = 1.645
Since the test statistic (2.38) is greater than the critical value (1.645), we reject the null hypothesis and conclude that there is sufficient evidence to support the alternative hypothesis at a significance level of α = 0.05.
b) For the sample result x = 51, the test statistic is given by:
z = (x - μ) / (σ /[tex]\sqrt{n}[/tex] ) = (51 - 50) / (8 / [tex]\sqrt{60}[/tex] ) = 0.53
Since the test statistic (0.53) is less than the critical value for a right-tailed test with α = 0.05, we fail to reject the null hypothesis and conclude that there is insufficient evidence to support the alternative hypothesis at a significance level of α = 0.05.
c) For the sample result x = 51.8, the test statistic is given by:
z = (x - μ) / (σ / [tex]\sqrt{n}[/tex] ) = (51.8 - 50) / (8 / [tex]\sqrt{60}[/tex]) = 1.58
Since the test statistic (1.58) is greater than the critical value for a right-tailed test with α = 0.05, we reject the null hypothesis and conclude that there is sufficient evidence to support the alternative hypothesis at a significance level of α = 0.05.
In summary, the test statistic represents the number of standard deviations between the sample mean and the hypothesized population mean, and the critical values represent the cutoff points for rejecting the null hypothesis. The decision to reject or fail to reject the null hypothesis depends on whether the test statistic falls within or outside the critical values for the given level of significance.

what is the probability that a senior nutrition major and then a sophomore non-nutrition major are chosen at random? express your answer as a fraction or a decimal number rounded to four decimal places.
Answer: 60%
Step-by-step explanation:
As mentioned earlier, we need to know the number of senior nutrition majors and sophomore non-nutrition majors to calculate the exact probability. Without this information, we cannot provide a specific answer to the question.
However, we can provide a general formula for computing the probability, assuming that the selections are made without replacement and the population of students is large enough to assume independence:
Probability of selecting a senior nutrition major and then a sophomore non-nutrition major = (Number of senior nutrition majors / Total number of students) × (Number of sophomore non-nutrition majors / (Total number of students - 1))
Once we have the values for the number of senior nutrition majors and sophomore non-nutrition majors, we can substitute them into this formula to obtain the probability, which will be a decimal number rounded to four decimal places.

PACKAGING A video game system is packaged in a box that is in the shape of a cube. The length of the packaging box is 4x^2 y^5 . What is the volume of the packaging box in terms of x and y?
Answer: 64x^6y^15
Step-by-step explanation:
If the packaging box is in the shape of a cube, then all its sides are equal in length. Let's call the length of each side "s".
We know that the length of the packaging box is 4x^2 y^5, so:
s = 4x^2 y^5
To find the volume of the packaging box, we need to calculate s^3 (since the box is a cube).
s^3 = (4x^2 y^5)^3
s^3 = 4^3 (x^2)^3 (y^5)^3
s^3 = 64x^6 y^15
Therefore, the volume of the packaging box in terms of x and y is 64x^6 y^15.

A liner function goes through the points (1, 2) and (-3, 5) Calculate the slope of the line in simplest form
M = Y2 - Y1
X2 - X1
Show your work, please
Slope (m) =
Answer:
To calculate the slope of the line that passes through the points (1, 2) and (-3, 5), we use the slope formula:
m = (Y2 - Y1) / (X2 - X1)
where (X1, Y1) = (1, 2) and (X2, Y2) = (-3, 5).
Substituting the values into the formula, we get:
m = (5 - 2) / (-3 - 1)
m = 3 / (-4)
Simplifying the fraction by dividing both the numerator and denominator by their greatest common factor of 1, we get:
m = -3/4
Therefore, the slope of the line in simplest form is -3/4.

We select H1: μ ≠ 10, we will estimate the true mean of the target population 10 outside of the confidence interval.
p-value = 0.025
Confidence interval = 95% = 0.95
Level of significance (α) = 1 - Confidence interval
Level of significance (α) = 1- 0.95
Level of significance (α) = 0.05
However we are aware that the null hypothesis is rejected if the p-value is less than 0.05.
Due to the fact that our p-value (0.025) is below the α, we may thus reject our null hypothesis with α level of significance.

The closer the data values are to the mean, the less variable they are, and the smaller the MAD.
A higher MAD shows that the data values are more variable and dispersed from the mean.

plss help
The measure of the missing angles of the right triangle are 57 degree and 33 degrees.
What are the measures of the missing angles?The sum of the interior angles of a triangle equals 180 degrees.
From the diagram:
Angle A = (4x - 7) degrees
Angle B = (3x - 15) degrees
Angle C = 90 degrees
In a right triangle, the sum of the two acute angles is 90 degrees.
So, we have:
angle A + angle B + 90 = 180 (sum of angles in a triangle)
(4x - 7) + (3x - 15) + 90 = 180
Solve for x
4x - 7 + 3x - 15 + 90 = 180
4x + 3x - 15 - 7 + 90 = 180
7x - 15 - 7 + 90 = 180
7x + 68 = 180
7x = 180 - 68
7x = 112
x = 112/7
x = 16
Therefore, the missing angles will be:
angle A = (4x - 7) = 4(16) - 7 = 57 degrees

Determine how many meters Penelope jogs in three laps
Penelope jogs a distance of 2898 meters in three laps around the rectangular playground.
To solve this problem, we need to first find the perimeter of the rectangle. For a rectangle with a length of L and a width of W, the perimeter P can be found using the following formula:
P = 2L + 2W
In this case, the length of the playground is 320 m and the width is 163 m. So, the perimeter of the playground is:
P = 2(320 m) + 2(163 m)
P = 966 m
This means that if Penelope jogs around the entire playground once, she will run a distance of 966 meters.
Since Penelope jogs three laps around the playground, we need to multiply the perimeter by 3 to find out how far she runs in total. So, the distance that Penelope jogs in three laps is:
Distance = 3 x P
Distance = 3 x 966 m
Distance = 2898 m
