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.
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

anwer: 7 the answer is 7
Answer:
Ruby needs 7 combined.
Step-by-step explanation:
If she needs 1/4 cup of powdered milk for one batch, then we multiply 1/4 by 4 to see how much she needs for 4 batches, which is 4/4, or one whole.
If she needs 3/2 cups of whole wheat for one batch, then we multiply 3/2 by 4 to see how much she needs for 4 batches, which is 12/2, or 6.
Then we combine 6 and 1, which is 7.

Joe bought g gallons of gasoline for $2.65 per gallon and c cans of oil for $3.45 per can. a. What expression can be used to determine the total amount Joe spent on gasoline and oil? b. If he bought 8.4 gallons of gasoline and 9 cans of oil, how much did he spend in all?
Step-by-step explanation:
PART A
a=total amount
c=cans of oil
g=gasoline
a=2.65g+3.45c
PART B
a=2.85(8.4)+3.15(6)
a=23.94+18.90

The Greatest Value of a country's paper money ever printed is 10 to the 8th power dollars. What is this amount written in standard form?
Answer: 1 × 10^8
Step-by-step explanation:
The standard form is written as:
= c × 10^n
For example if we are told to change 200 to standard form, it'll be:
200 = 2 × 10^2
Therefore, 10 to the 8th power in standard form will be:
= 1 × 10^8

Steve had 48 chocolates but decided to give 8 chocolates to each of his coworkers,
How many chocolates does Steve have left?
Wite your answer as an expression
chocolates
Answer:
48 - 8c
Step-by-step explanation:
let c be the number of coworkers
48 - 8c would be the expression because it starts with 48 and for every coworker 8 is subtracted.
Answer:
n = 48 - 8x
Step-by-step explanation:
n = how many chocolates Steve has left.
x = how many coworkers

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

Answer:
60 milligrams
Step-by-step explanation:
just cross multiply! percentages are just fractions of 100. so you can say that [tex]\frac{45}{x} =\frac{75}{100}[/tex]
multiple 75 by x and 45 by 100 and you get
4500=75x
divide both sides by 75 and you get 60
