Suppose that 2 were subtracted from each of the values in a data set that
originally had a standard deviation of 5.5. what would be the standard
deviation of the resulting data?
o a. 5.5
o b. 7.5
o c. 3.5
o d. 2

597

step-by-step explanation:

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
