ANSWER

$Area = 196 \: in^{2}$

EXPLANATION

The area of the smaller square is 4 in².

This means that the smaller square has length,

$l = 2 \: in$

The scale factor of the dilation is

$k = 7$
The length of the bigger square becomes,

$L = 7 \times 2 = 14 \: in$

The area of the dilated square is

$Area=L^2$

$Area=14^2 = 196 \: in^{2}$

The correct answer is option D.

Z-score is basically another term for the specific number of standard deviations. I suppose we can assume normality here, even though it isn't given, so I'd make a rough sketch.

Otherwise, just use the basic formula:

$z_{score} =\dfrac{x-\mu}{\sigma}$
