Answer:
Step-by-step explanation:
We know the property of derivative: 
Given function : 
Differentiate both sides with respect to x , we get

[By Chain rule]

[Since
, where a is scalar and
]

Hence, the derivative of the given function is
.
425 / 50 = 8,5
There you go.
Answer:
Binomial probability, with 
Step-by-step explanation:
For each time Mookie Betts went to bat, there were only two possible outcomes. Either he got a base-hit, or he did not. The probability of getting a hit on each at-bat is independent of any other at-bat. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
His average was 0.352.
This means that 
Assume he has five times at bat tonight in the Red Sox-Yankees game.
This means that 
a. This is an example of what type of probability
Binomial probability, with
