Step-by-step explanation:
Maria has two routes, E and W, she can take when commuting to work. Both routes go through a railroad crossing, and sometimes she needs to stop at the crossing to allow trains to pass. She claims that the proportion of times she needs to stop when taking route E is different from the proportion of times she needs to stop when taking route W. She conducted the following hypothesis test at the significance level of α=0.10.
H0: pE=pW
Ha: pE≠pW
In the hypotheses, pE represents the proportion of times she needs to stop at the crossing when using route E, and pW represents the proportion of times she needs to stop at the crossing when using route W.
All conditions for inference were met, and the resulting p-value was 0.37. Which of the following is the correct decision for the test?
The p -value is less than alpha , and the null hypothesis is rejected. There is convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is different for the different routes.
The p -value is greater than alpha , and the null hypothesis is not rejected. There is convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is the same for the different routes.
The p -value is greater than alpha , and the null hypothesis is rejected. There is not convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is different for the different routes.
The p -value is greater than alpha , and the null hypothesis is not rejected. There is not convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is different for the different routes.
The p-value is greater than α, and the null hypothesis is rejected. There is convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is different for the different routes.
Answer:
The p-value is greater than α , and the null hypothesis is not rejected. There is not convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is different for the different routes.
Step-by-step explanation:
The claim is not supported. Since 0.37>0.10, the null hypothesis is not rejected. There is not convincing statistical evidence that the proportion of times she needs to stop at the crossing is different for the different routes.

The triangles below are similar.
Which statement about the triangles is true?
Write the equation of the line that passes through the point (5, 6) and a slope of -2
Answer:
y = -2x + 16
Step-by-step explanation:
So first you plug in the values you know into the slop int. form, equation, in which it is y = mx +b. When you plug in the slope value then you will get the equation of y = -2x +b, in which then you have to solve for the b value.
In order to solve for the b value, you then plug in the x and y values of the coordinate that is given so what you would do is this: 6 = -2(5) +b
6 = -10 +b
16 = b
So then you find out b is 16 in which you just plug back into the equation. So finally you write the equation, y = -2x+16.

Find the volume of the cylinder. Use 3.14 for pi. Round your answer to the nearest tenth.
Answer:
The formula for the volume of a cylinder is V=Bh (where B is the base) or V=πr2h . The radius of the cylinder is 9 ft and the height is 6 ft. Substitute 9 for r and 6 for h in the formula V=πr2h = (3.14) (9) (2) (6) =339.12
Step-by-step explanation:
Now C=339.12 round to the nearest tenth is 339.1

The test will cover 120 pages in his textbook. He has read only 36 pages. If he plans to read an equal amount every day of the week to finish the 120 pages, how much must read each day?
Answer:
He must read each day=12 pages
Step-by-step explanation:
We are given that
Total number of pages in textbook=120
He has read number of pages=36
Number of days in a week=7
We have to find the number of pages read each day to finish 120 pages in a week.
Number of pages remaining for reading=120-36
Number of pages remaining for reading=84
Now,
Number of pages read each day=[tex]\frac{84}{7}[/tex]
Number of pages read each day=12
Hence, he must read each day=12 pages

If the measure of AngleB is 40°, what measures can AngleA and AngleC be? Select the three correct answers. 20° and 30° 30° and 110° 55° and 85° 60° and 90° 70° and 70°
Answer:
30° and 110°
55° and 85°
70°and 70°
Step-by-step explanation:
Given that :
Angle B = 40°
Sum of angles in a triangle :
Angle (A + B + C) = 180°
A + 40 + B = 180
A + C = 180 - 40
A + C = 140°
From the Given options ;
The sun of the Angles Given must add up to 140°
Hence,
30° and 110° = 140°
55° and 85° = 140°
70°and 70° = 140
