Lynn measured the length of her front yard by counting her strides. The yard measured 18.5 feet long. Emily measured the same yard using a tape measure, and found that it was 20 feet long. What was the percent error of Lynn's measurement?

8.11%

Step-by-step explanation:

We need to find the percentage error. We can follow the formula shown below:

Where

PE is the Percentage Error

New is the newest measure (given as 20 feet)

Orig is the original, or first, measure (given as 18.5)

Substituting and finding the PE:

Tagging the percentage , percent error is about 8.11%

360/29

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
