Multiply all terms by 2 to get rid of fractions
2x+10=28-x

Add x to both sides
3x+10=28

Subtract 10 from both sides
3x=18

Divide both sides by 3
x=6

Final answer: x=6

Which residual plots indicate that the original data set has a linear relationship? Check all that apply
Amanda [17]

Answer: A, B and E

Step-by-step explanation:

A residual values should be equally and randomly spaced around the horizontal axis. If the plot looks like any of the images in C and D, then the data set is probably not a good fit for regression. A non-linear pattern is more appropriate.

I'm completely lost about to work these problems

2) The formula for the area of a circle is: A = \pi r x^{2}
Differentiate both sides to get: \frac{dA}{dt} =  2 \pi r \frac{dr}{dt}
where dA/dt is the rate of change of the area of the circle with respect to time, and dr/dt is the rate of change of the radius of the circle with respect to time.
We want to know dA/dt when r = 3 and dr/dt = 2, so plug those into the equation to get: \frac{dA}{dt} =2 \pi (3)(2) = 12 \pi feet per second.

3) The amount of revenue gained in a week is equal to the price per good times the number of goods sold, or R = x*p. Thus, R = x(150-.002x) = 150x - .002x^2. Differentiate both sides to get: \frac{dR}{dt} = 150 \frac{dx}{dt} - .004x \frac{dx}{dt}, where dR/dt is the rate of change of revenue and dx/dt is the rate of change of production.
We want dR/dt when dx/dt = 200 and x = 2000, so plug those in to get: \frac{dR}{dt} = 150(200) - .004(2000)(200) = 28400
