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.
You can say 1/2 = 8/16 so the answer is : 9/16 + 8/16 = 17/16 = 1.06 :))
i hope this is helpful
have a nice day
Answer
i believe the answer would be the third photo if the third photo for you is the one that doesn’t pass the vertical line test
Explanation
if the relation is a function no two pints should touch going down hence the vertical line test
hope this helps and have a wonderful day :)
Find the least common multiple of 14 and 16.
14 = 7*2 ----> multiply by 8 ----> 8*7*2 = 112
16 = 8*2 ----> multiply by 7 -----> 7*8*2 = 112
The LCM is 112. This means it will be 112 minutes before they dump water at the same time.
112 min = 1 hr 52 min
3:20 + 1hr 52 min = 5:12
For the next time, add another 112 minutes
Answers: 5:12 PM and 7:04
