Imagine a regression line that relates y = average systolic blood pressure to x = age. The average blood pressure for people 40
mart [117]

Answer:

2.0

Step-by-step explanation:

x = age

y = average systolic blood pressure

x₁ = 40 years old, y₁ = 110 systolic blood pressure

x₂ = 50 years old, y₂ = 130 systolic blood pressure

\text{Slope of a line}=m=\frac{y_2-y_1}{x_2-x_1}\\\Rightarrow m= \frac{130-110}{50-40}\\\Rightarrow\frac{20}{10}\\\Rightarrow m= 2.0

∴ Slope of the regression line is 2.0

Please help solve <br><br> 7 (x + 8) + 4 = -11 (x - 8) -9
Paladinen [302]

Answer:

x=1 1/18

Step-by-step explanation:

7(x+8)+4=-11(x-8)-9

distribute- 7x+56+4=-11x-88-9

7x+60=-11x+79

subtract 60 from both sides (60),(79)

7x=-11x+19

add 11x on both sides

18x/18 and 19/18

which gives you x=1 1/18 or 19/18
