10(1 + 3<em>b</em>) = -20

Isolate <em>b</em>.

Apply the distributive property: <em>a</em>(<em>b</em> + <em>c</em>) = <em>ab</em> + <em>ac.</em>

10(1 + 3<em>b</em>) = -20

10 + 30<em>b</em> = -20

Subtract 10 from both sides.

10 + 30<em>b</em> - 10 = -20 - 10

30<em>b</em> = -30

Divide both sides by the coefficient, 30.

<em>b</em> = -1

<h3>Answer:</h3>

-1

The athlete that has the shortest training ride is athlete A.

The athlete that has the shorter range is Athlete B.

The athlete that has the greater median is Athlete B.

The athlete that has the greater IQR is  athlete A.

<h3>What are the summary statistics?</h3>

A box plot is used to study the distribution and level of a set of scores. The box plot consists of two lines and a box. the two lines are known as whiskers. The first whisker represents the minimum number and the second whisker represents the maximum number. The difference between the whiskers is known as range.

Range of Athlete A = 36 - 13 = 13

Range of Athlete B = 30 - 19 = 11

Training ride of  Athlete A = 16

Training ride of  Athlete B = 21

On the box, the first line to the left represents the lower (first) quartile. The next line on the box represents the median. The third line on the box represents the upper (third) quartile.

Median of  Athlete A = 20

Median of  Athlete B = 25

IQR of  Athlete A = 30 - 16 = 14

IQR of  Athlete B = 28 - 21 = 7
