Answer:
Option C is correct.
Step-by-step explanation:
Given is a function of x
Now, the average rate of change of over the interval [1,b] is 20 for b > 1.
Now the expression can be written from the above condition is
.......(1)
Therefore, the above equation (1) can be used to find the value of b and option C is correct.

Based on the information given, it should be noted that the mean and standard deviation of Y will be 0.4899 and 0.699 respectively.
<h3>Calculating the mean.</h3>
Based on the information given, it should be noted that the probability distribution for y will be:
Y 0 1. 2
Probability 0.63. 0.25. 0.12
The mean of Y will be:
= (0 × 0.63) + (1 × 0.25) + (2 × 0.12)
= 0 + 0.25 + 0.25
= 0.49
The variance will be 0.4899. Therefore, the standard deviation will be:
= ✓0.4899
= 0.699
