Answer:
B. 93%
Step-by-step explanation:
Find the z-score:
z = (x − μ) / σ
z = (122 − 100) / 15
z = 1.47
Find the probability using a calculator or z-score table.
P(Z < 1.47) = 0.93
Answer:
134
Step-by-step explanation:
Answer:
Option B
Step-by-step explanation:
Average rate of change of a function 'f' in the interval x = a and x = b is given by,
Average rate of change of change = 
Given function is,
g(x) = 
We have to calculate the rate of change in the interval [-4, 3],
Average rate of change = 
g(3) = 
= 2.5 + 1
= 3.5
g(-4) = 
= -1 + 1
= 0
Average rate of change = 
= 
= 
Therefore, Option B will be the answer.
