(brainiest and 50 points)A data set is made up of these values. 1, 4, 5, 6, 6, 9, 11
Find the interquartile range.
A. 4 – 1 = 3

B. 11 – 9 = 2

C. 11 – 1 = 10

D. 9 – 4 = 5

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula,equation,to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.

Astudent survey asked: "how tall are you (in inches)? " here's the data: 67, 72, 73, 60, 65, 86, 72, 69, 74 give the five number summary. a. median: 73, mean: 70.89, iqr: 5, min: 60, max: 74 b. 60, 66, 72, 73.5, 86 c. 60, 67, 72, 73, 74 d. 0, 60, 70, 89, 74, 100

Which expression gives you the distance between the points (5,1)and(9,-6)
