X = 15
X + 90 = 7x
X = 7x - 90
X - 7x = -90
-6x = 90
Divide both sides by -6
X = 15
The answer is C. 1080. i got this by multiplying 180 by 6.
The regression equation:
y = m x + b
m = ( 57 - 50 ) / ( 178 - 168 ) = 7 / 10 = 0.7
50 = 0.7 * 168 + b
50 = 117.6 + b
b = 50 - 117.6
b = - 67.6
y = 0.7 * x - 67.6The graph is in the attachment.
The weight of supermodel who is 171 cm tall:
y = 0.7 * 171 - 67.6 = 119.7 - 67.6 =
52.1 kg
Answer:
x times 2y times pi
Step-by-step explanation:
The formula is height times diameter times pi. diameter is two times the radius, and 2 times y is 2y. the rest is simple. multiply them together an you get the answer
