Options:
a. His predicted weight loss was 5.5 pounds higher than his actual weight loss.
b. His actual weight loss was 5.5 pounds higher than his predicted weight loss.
c. His actual weight loss was 5.5 pounds higher than it would have been if he didn’t exercise.
d. His predicted weight loss was 5.5 pounds higher than it would have been if he didn’t exercise.
Answer:
Option B. His actual weight loss was 5.5 pounds higher than his predicted weight loss.
Step-by-step explanation:
In regression analysis, the difference between the observed value of the dependent variable (y) and the predicted value (ŷ) is called the residual (e). Residual value= Observed value - Predicted value.i.e. e = y - ŷ
Since the residual weight of the client was 5.5 pounds, this means that His actual weight after compliance with the exercise program his 5.5 pounds higher than what he predicted.
Answer:
It's 3
Step-by-step explanation:
1 +2 =3

Answer:
z=24 y=5 x=12
Step-by-step explanation:
x+8=20 x=20-8 x=12
z+1=25 z=25-1 z=24
y+10=15 y=15-10 y=5
Use this systems of equations to solve:
x = first antifreeze
y = second antifreeze
Isolate y.
x + y = 15
Subtract x from both sides.
y = -x + 15
Substitute y into the other equation.
.2x + .12(-x + 15) = .18(15)
Simplify.
.2x - .12x + 1.8 = 2.7
Subtract 1.8 from both sides.
.08x = .9
Divide both sides by .08
x = 11.25
Substitute x in the equation that we isolated y in.
y = -11.25 + 15
y = 3.75
11.25 L of the first antifreeze and 3.75 L of the second.
