Suppose that there were a negative correlation between the variables a and b.
if bis 60 when a is 8, which of these is most likely to be the value of b when a
is 16?
o a. 75
o b. 90
o c. 30
o d. 60

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

other answer is correct. i had used the radius of the radius somehow. a website:

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a
