Answer && Step-by-step explanation:

Use what we know are given variables (answer choices)

we know middle is 15, 4x+7 must be > 15 plug in variables

7.5 makes it 35 but that is too big

4 is also >  but it makes it slightly too big at 23 but when i divide by 3 i get 7.6, which mult 2 ~= 15

never the less, lets try it at top

4+3=7

make a triangle above 15, this will == half of 15 which is 7.5

7 is closest, I would guess 4 based on this alone.

Answer:

A

Step-by-step explanation:

In the histogram described by the first option, the peak (18) is located at 40-50. Also, a frequency of zero is observed for range 10-20. The cluster from 20–50 means that most of the data is between this range, in fact, only 1 point is located at range 0 - 10, outside this cluster.
