Answer:

y = -3x + 60

Step-by-step explanation:

For the answer to the question above,

let x = number of weeks let y = amount of waste.

The linear equation may be expressed as,y = mx + b

m and b are the slope and y - intercept, respectively. Substituting the corresponding values,

(Week 5) 45 = 5m + b

(Week 10) 30 = 10m + b

Solving for m and b gives the values as m = -3 and b = 60. Thus, the equation is

y = -3x + 60

<h2>Error percentage</h2>

The amount of mistakes is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

Given

Annie estimates that the height of a bookcase is 78.25 in.

The actual height is 75.50 in.

The error percentage.

<h3>How to find the error percentage?</h3>

We know the formula for the error percentage.

$\rm \% Error = \dfrac{Measured \ value- Actual\ value}{Actual\ value} * 100\\\\ \% Error = \dfrac{78.25 - 75.50}{78.75}*100\\\\ \% Error = \dfrac{3.25}{78.75}*100\\\\ \% Error = 0.0413*100\\\\ \% Error = 4.13 \%$

The error percentage is 4.13%.
