Answer:
This system has no solution
Step-by-step explanation:
-(11+4y)+4y=-10
no solution
Step-by-step explanation:
3/4:2/5=3/4×5/2=15/8
3/8 ÷ 2/12=3/8 ×12/2=36/16=9/4
Answer:

Step-by-step explanation:
Given that

We have slope of linear regression line is

So regression line would be of the form
(since it passes through xbar, y bar)

is the equation of regression line.
Answer:
Volume of the tank = 636 ft³
Step-by-step explanation:
Formula for the volume of a cylinder is,
V = πr²h
Where r = radius of the cylinder
h = height of the cylinder
By substituting the values of radius and height of the water tank given in the question,
V = 
= 202.5π
= 202.5 × (3.14)
= 635.85 ft³
≈ 636 ft³
Therefore, volume of the cylindrical water tank is 636 ft³.
You cannot solve this equation, because you have no y or x values. However, you can change the equation to equal x.
