It is indeed 70, you divid 63 by 90 and your answer should be .07 so if you add that to your starting 63 you get 70

Abigal wrote a computer program that generates two random numbers between one and 11. When she runs it, what is the probability

dlinn [17]

Assuming uniform distribution and independence, then
P(1st number less than 8 and 2nd number less than 8) = 
P(1st number less than 8)*P(2nd number less than 8) = 
(7/12)*(7/12) = about 34%

Let f(x)=−14(x+4)2−8 .

nevsk [136]

Answer:
Average rate of change = -112

Explanation:
The average rate of change = $\frac{f(b) - f(a)}{b - a}$
where:
b is the upper limit = 2
f(b) = f(2) = -14(2+4)² - 8 = -512
a is the lower limit = -2
f(a) = f(-2) = -14(-2+4)² - 8 = -64

Substitute with these values in the above equation to get the average rate of change as follows:
average rate of change = $\frac{-512 - (-64)}{2 - (-2)} = -112$

Hope this helps :)
