It is given that f(t) = -16t² + 32t + 90
<span>The average rate of change will be calculated as following
</span>
At t₁ = 4 ⇒⇒⇒ f(t₁) = -16*(4)² + 32*(4) + 90 = -38
At t₂ = 6 ⇒⇒⇒ f(t₂) = -16*(6)² + 32*(6) + 90 = -294
∴
<span>So, The average rate of change of f(t) from t = 4 seconds to t = 6 seconds is
128 feet per second .

Step-by-step explanation:63
Answer:
So then the correct answer would be:
B) .9996
Step-by-step explanation:
The exact way to solve this problem is using the binomial distribution, assuming that our random variable of interest is "number of students living in apartments" represented by X and
And we want this probability:
So we see that we satisfy the conditions and then we can apply the approximation.
If we appply the approximation the new mean and standard deviation are:
And then
And we are interested on the following probability:
So then the correct answer would be:
B) .9996
Answer B! Hope this helps
