The correct answer is: 23

Explanation:

Given function:

$f(x) = 3x^2 - 2x + 7$ ---- (A)

f(-2) means that we have to put x = -2 in equation (A):

$f(-2) = 3(-2)^2 - 2(-2) + 7 \\ f(-2) = 3*4 + 4 + 7 \\ f(-2) = 12+4+7 \\ f(-2) = 23 \\$

Hence the correct answer is: f(-2) = 23.

Answer:

a. z-score for the number of sags for this transformer is ≈ 1.57 . The number of sags found in this transformer is within the highest 6% of the number of sags found in the transformers.

b. z-score for the number of swells for this transformer is ≈ -3.36. The number of swells found in the transformer is extremely low and within the lowest 1%

Step-by-step explanation:

z score of sags and swells of a randomly selected transformer can be calculated using the equation

z= $\frac{X-M}{s}$ where
