Answer:

A

Step-by-step explanation:

Let's set hours as h.

We know that she earns 5 dollars an hour. If, for example, she worked 2 hours, she would have earned 2*5=10 dollars. This is 5h.

Next, we know that she got 186 dollars in tips. Tips means that she earned extra money, so therefore, the equation is 5h+186, or A

If EF bisects CD, CG = 11x-5, GD=13x-15, and EF=12x+2, find EF.
mamaluj [8]

Answer:

EF =  62

Step-by-step explanation:

Given

CG = 11x-5

GD=13x-15

EF=12x+2

Required

Determine EF

Since EF is a bisector of CD at G, then

CG = GD

11x- 5 = 13x - 15

Collect Like Terms

11x - 13x = 5 - 15

-2x = -10

Solve for x

x = -10/-2

x = 5

Substitute 5 for x in EF=12x+2

EF = 12 * 5 + 2

EF =  60+ 2

EF =  62

Ted and Meg have each drawn a line on the scatter plot shown below:
expeople1 [14]

Answer:

A.)Line P, because it is closest to most data points

Step-by-step explanation:

The line of best fit is a line which best represents the data and the data points are closely related to it.

It is also known as a trend line.

The line of best fit may pass through, some , none or all of the data points.

Also if the scatter plot does not pass through all the data point then the magnitude of positive residual must be approximately equal to the magnitude of negative residual of the data points.

Hence, by looking at the scatter plot we see that all the data points lie above Line R.

Hence, the Line R will not be a line of best fit.

But all the data points lie close to the line P , hence it act as a line of best fit.
