The height of an 8th grader is modeled using the normal distribution shown below. The mean of the distribution is 61.2 in and the standard deviation is 1.3 in.
In the figure, there are three missing values to fill in along the axis. The midde value is under the highest part of the curve. And, the left
and right values are each the same distance away from the middle value.
Use the empirical rule to choose the best value for the percentage of the area under the curve that is shaded, and nil in the missing values
along the axis.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.

answer:   c ?

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
