A. median = 80, Q1 = 60, Q3 = 110

Step-by-step explanation:

Box plots have the IQR, median, and range on them. So let's solve for each of those measures.

Median

The median is the middle number in the set when they're ranked from smallest to largest. The median of a 15-number set will be the eighth answer, so the median is 80.

IQR

The IQR is the inter-quartile range. It's the median of the lower and upper half. We can divide this set into the numbers from 44 - 80 and the numbers from 90-135, then find the median of each of these.

The Q1 (first quartile) is the median of the lower half, which is the 4th number. So Q1 = 60.

The Q3 (third quartile) is the median of the upper half, which is the 12th number. So Q3 = 110.

2

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
