Answer:

a rational number

Step-by-step explanation:

1) First, find the sum of $\frac{4}{7} +\frac{-1}{3}$ :

$\frac{4}{7} + \frac{-1}{3} \\= \frac{12}{21} - \frac{7}{21} \\= \frac{5}{21}$

2) Any number that can be written as a fraction is a rational number. Therefore, the sum, $\frac{5}{21}$ , is rational.

A box-and-whisker plot shows the distribution of a set of data along with... Quartiles are values that divide a set of data into four equal parts. The second Quartile ( designated Q2) also called the median or the 50th percentile (cuts data set in half ).
