Answer:
Option C) 0.830
Step-by-step explanation:
We are given the following in the question:
The heights (in inches) of males in the United States are believed to be approximately normally distributed with mean
.
Sample size, n = 25
Sample mean,
= 69.72 inches
Standard deviation,
= 4.15 inches
We have to find the standard error of
.
Standard error =

Thus, the standard error of
is 0.83 inches.
The correct answer is
Option C) 0.830
Plug in the possible answers into the equation and solve for x. x=0
Answer:
36
Step-by-step explanation:
Given
x² + 12x
To make the polynomial a perfect square
add ( half the coefficient of the x- term)²
= x² + 12x + 6²
= x² + 12x + 36
= (x + 6)² ← a perfect square
Y = (x - 3)² + 53
y = (x - 3)(x - 3) + 53
y = (x(x - 3) - 3(x - 3)) + 53
y = (x(x) - x(3) - 3(x) + 3(3)) + 53
y = x² - 3x - 3x + 9 + 53
y = x² - 6x + 62
