Micah's velocity = 1 box / 15 minutes = 1/15 box/minute

Sidney's velocity = 1/x

Micah's velocity - Sidney's velocity = 1 box / 20 minutes = 1/20 box/mitue


1/15 - 1/x = 1/20

1/x = 1/15 - 1/20

Answer: option a. 1/15 - 1/20 = 1/x

Which data set could be represented by the boxplot shown? (1 point)
lidiya [134]

The second data set represents the boxplot because in the box plot the measure of statistics is the same as the data set option second is correct.

<h3>What is the box and whisker plot?</h3>

A box and whisker plot is a method of abstracting a set of data that is approximated using an interval scale. It's also known as a box plot. These are primarily used to interpret data.

We have given a data set and a box plot shown in the picture.

From the boxplot we can see:

Minimum value = 2

Q1 = (2+4)/2 = 3

Median = (4+6)/2 = 5

Q3 = (8+10)/2 = 9

Maximum value = 10

The second data set:

{2, 3, 3, 4, 5, 5, 8, 10, 10}

Minimum value = 2

Q1 = (2+4)/2 = 3

Median = (4+6)/2 = 5

Q3 = (8+10)/2 = 9

Maximum value = 10

Thus, the second data set represents the boxplot because in the box plot the measure of statistics is the same as the data set option second is correct.
