Answer:
Options B and D are correct.
Step-by-step explanation:
The given equation is :
We can see that it is a quadratic equation.
Hence it is non linear.
The rate is dependent on x, so it does not have a constant rate of change also.
We can check this :
At x= 0, y = 64
At x=1, y =
Hence, the function does not have a constant rate of change.
So, the answer is :
- B. The function is a nonlinear function.
- D. The function does not have a constant rate of change.

Answer:
This indicates that the chances of the mean life span today is greater than 70 years is 0.5871
Step-by-step explanation:
The past year showed an average life span of 71.8 years.
Population standard deviation = 8.9 years
We are supposed to find the mean life span today is greater than 70 years
i.e. P(X>70)
Formula :
Z=−0.202
P(X<70)=0.4129
P(X>70)=1-P(X<70)=1-0.4129=0.5871
Hence This indicates that the chances of the mean life span today is greater than 70 years is 0.5871
