Continued from previous. For a certain population, a health and nutrition survey finds that:
the average weight is 175 pounds with a standard deviation of 42 pounds, the average height is 67 inches with a standard deviation of 3 inches, and the correlation coefficient is 0.7.
Furthermore, the scatterplot of height on weight is an oval-shaped cloud of points.
Complete the sentence:
For this population at the time of the survey, each extra pound of weight is associated with extra inches in height, on average.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

answer: i guess 5 units?

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
