Answer:
39
Step-by-step explanation:
(16-2w)^2 + (3y÷3z)
Let w=5 y=9 and z=3
(16-2*5)^2 + (3*9÷3*3)
PEMDAS says parentheses first
Multiply and divide in the parentheses
(16-10)^2 + (27÷9)
Then add and subtract in the parentheses
(6)^2 + (3)
Now the exponent
36 +3
39
Answer: C
Step-by-step explanation:
The formula to find average rate of change is
. Since the problem is asking for the average rate of change from the second to fifth year, we plug in a=2 and b=5.

f(5)=420.4
f(2)=408.04

Now, we get 4.12 dollars per year for the average rate of change.
The base is -4 and the exponent is 6

Answer:
a)P=0.42
b) 
Step-by-step explanation:
We have a binomial distribution, since the result of each experiment admits only two categories (success and failure) and the value of both possibilities is constant in all experiments. The probability of getting k successes in n trials is given by:

a) we have k=2, n=10 and p=0.01:

b) We have,
, Here P is the probability that at least one particle will penetrate the shield, this probabity has to be equal or greater than 0.95. Therefore, this will be equal to subtract from the total probability, the probability that the particles do not penetrate raised to the total number of particles.
