It is given that the mean is 79.1 inches and standard deviation is 3.0 inches so it follows:

So the value from 75 to 81 is given by:

Use the table or a software to get the probability values and substitute to get the probability value as:
The probability is 0.6509.
Answer:
2
Step-by-step explanation:
Point c is at (1, 2)
point d is at (2, 4)
rate of change formula
(f(d) - f(c))/2 - 1
f(2) = 4
f(1) = 2
4-2/1 = 2
Answer:
Step-by-step explanation:
96 = 2w²
48 = w²
√48 = w
√(16)(3) = w
± 4√3 = w
± 6.93
w = 6.93, -6.93
