identify the outliers in the following data sets. include calculations.
set one: 5.5, 6.2, 4.9, 9.1, 5.3, 1.9, 4.8, 15.8, 4.2, 6.6, 5.6
set two: 6.1, 3.9, 6.4, 10.6, 4.4, 4.5, 1.6, 11.2, 0.8, 3.9, 6.5

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

(3x-8) or (3x+8)

step-by-step explanation:

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
