V = 576 pi cm^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
V = pi * (6)^2 * 16
V = pi *36*16
V = 576 pi cm^3
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](https://tex.z-dn.net/?f=%5Ctext%7BSlope%20of%20a%20line%7D%3Dm%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5C%5C%5CRightarrow%20m%3D%20%5Cfrac%7B130-110%7D%7B50-40%7D%5C%5C%5CRightarrow%5Cfrac%7B20%7D%7B10%7D%5C%5C%5CRightarrow%20m%3D%202.0)
∴ Slope of the regression line is 2.0
A centimetre is the most appropriate unit
