Answer: the other person has the graph, i'm just listing the other answers

b) Find the equation of the trend line (line of best fit). Show your work. (2 points)

The equation of the trend line is y = 2x.

c) Predict the amount of tips that would be collected if 100 customers were served at the restaurant on a given day. Explain your reasoning. (2 points)

$200 would be collected if 100 customers were served because according to the trend line each customer gives about a $2 tip.

d) Explain how to use the regression calculator to make a reasonable prediction

a data table. (2 points)

First, determine which is the independent variable and which is the dependent variable. Next, enter the data pairs into the regression calculator. Then substitute the value for one variable into the equation produced by the calculator, and lastly make your prediction.

Step-by-step explanation:

this is what i said, sorry for the late response

Determine the volume of the solid that lies between planes perpendicular to the x-axis at x=0 and x=4. The cross sections perpen

OverLord2011 [107]

Answer:

Volume = 16 unit^3

Step-by-step explanation:

Given:

- Solid lies between planes x = 0 and x = 4.

- The diagonals rum from curves y = sqrt(x) to y = -sqrt(x)

Find:

Determine the Volume bounded.

Solution:

- First we will find the projected area of the solid on the x = 0 plane.

A(x) = 0.5*(diagonal)^2

- Since the diagonal run from y = sqrt(x) to y = -sqrt(x). We have,

A(x) = 0.5*(sqrt(x) + sqrt(x) )^2

A(x) = 0.5*(4x) = 2x

- Using the Area we will integrate int the direction of x from 0 to 4 too get the volume of the solid:

V = integral(A(x)).dx

V = integral(2*x).dx

V = x^2

- Evaluate limits 0 < x < 4:

V= 16 - 0 = 16 unit^3
