Answer:
-9u^7v - 6u^5v - 21u^2v
Step-by-step explanation:
Assume independence because there are probably a lot of widgets. 1/100 x 1/100 = 1/10,000
its simple X is domain Y is range so the answer is
A
Answer:

Therefore the probability that a randomly selected student has time for mile run is less than 6 minute is 0.0618
Step-by-step explanation:
Normal with mean 6.88 minutes and
a standard deviation of 0.57 minutes.
Choose a student at random from this group and call his time for the mile Y. Find P(Y<6)


y ≈ normal (μ, σ)
The z score is the value decreased by the mean divided by the standard deviation

Therefore the probability that a randomly selected student has time for mile run is less than 6 minute is 0.0618
