Im an Ace Rank I know im right BRAINLIEST PLZ

First Quartile:

14

Third Quartile:

19

Median:

17.5

Interquartile Range:

5

Step-by-step explanation:

In descriptive statistics, the interquartile range (IQR), also called the midspread, middle 50%, or H‑spread, is a measure of statistical dispersion, being equal to the difference between 75th and 25th percentiles, or between upper and lower quartiles, IQR = Q3 − Q1. In other words, the IQR is the first quartile subtracted from the third quartile; these quartiles can be clearly seen on a box plot on the data

12

Step-by-step explanation:

i guessed it because i guessed other questions and got them right

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9
