Heights (in centimeters) and weights (in kilograms) of 7 supermodels are given below. Find the regression equation, letting the
Delvig [45]
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 - 67.6
The 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

HELP ASAP
Natalija [7]

Answer:

The equation of the function: y = mx + b

  • m = slope = (y₂ - y₁)/(x₂ - x₁) = [5 - (-3)]/(4 - 0) = (5 + 3)/4 = 8/4 = 2
  • b = y-intercept = -3

Therefore, the equation is <u>f(x) = 2x - 3</u>

When x = 0, f(x) = 2(0) - 3 = <u>-3</u>

When x increases by 1, f(x) increases by <u>2</u> (slope = the rate of change)

Evaluate 7 + (-3x^2) For x = 0<br><br>A. -2<br>B. 0<br>C. 4<br>D. 7​
Goryan [66]

Answer:  D. 7

Step-by-step explanation:

The problem tells you that x = 0 so replace everything that is x in the equation with 0 so the problem becomes

7 + (-3(0)^2)

Now we just solve the problem normally.

solve the problem in the parenthesis first, we must multiply -3 times 0^2 is 0

so now our problem is 7 + 0 which is 7
