1 Which set of data has a range of 11? A. 5, 18, 4,3,6,9,16 B. 2, 3, 11, 11, 5, 12, 15 c. 7, 10, 11, 13, 15, 21 D. 6,9, 3, 14,7,8,9 2 The mean of a set of three data points,​

(opt.d) Is the set of dates with a range of 11.

Step-by-step explanation:

Range = Highest - Lowest = 11

a) 18 - 3 = 15

b) 21 - 7 = 14

c) 15 - 2 = 13

d) 14 - 3 = 11 (✔)

(opt.d) Is the set of dates with a range of 11. The answer is D. Let me know if I'm correct.

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
