Answer:
180°
Step-by-step explanation:
Since a sprinkler rotates 90°, pauses,and then rotates another 90°
So, here total degrees be like
= 90° + 90°
= 180°
hence, The number of degrees did it rotate altogether should be considered as the 180 degrees.

Please let me know if you want me to add an explanation as to why this is the answer/how I got this answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
Answer:
As probability of that happening is very small; Yes, 33.6 is less than 35.6 grams because it provide strong evidence that the mean weight of the bags is lower than the 35.6 grams listed on the package.
Step-by-step explanation:
For a normal distribution Z-score

Given that :
the mean (
) = 35.6
standard deviation (
) = 5.2
sample size (n) = 35
standard error: 


The probability that a random sample of 35 bags has a mean weight of 33.6 grams or less is :
P(X<33.6) = P(Z < - 2.28)
= 0.0114
Conclusion:
As probability of the happening is very small; Yes, 33.6 is less than 35.6 grams because it provide strong evidence that the mean weight of the bags is lower than the 35.6 grams listed on the package.
