He makes 240. All you do is make the 8% to a decimal (.8) and them multiply it by 3000. (3000*.08) It should be 240.
Answer:
<u>B. There is sufficient evidence that the mean of the pressure required to open a certain valve has changed. </u>
Step-by-step explanation:
We make this conclusion based on these reasons:
- We are told that the "null hypothesis was rejected" after the <em>"manager feels that the pressure variability has changed.,</em> meaning the <u>null hypothesis was the opposite of what occurred; that is to say, it is the alternate hypothesis that proved true instead.</u>
- <em>"changes in the manufacturing process"</em> form what can be called "sufficient evidence" that the mean of the pressure required to open the valve has changed, thereby going against the null hypothesis.
It is based on the above reasons that the null hypothesis was rejected.
Hello!
Let's find the area and see!
A = s^2
A = 3^2
A = 6 ft^2
Now, if you double 3, you get 6. 3 × 2 = 6 Find the area:
A = 6^6
A = 36 ft^2
ANSWER:
No, the area will not be doubled. The area was 9 ft^2 when the sides were 3 feet long. If you double 9, you get 18, since 9 × 2 = 18.
36 is not the double of 9, so no, the area is not double.
