\text{The expression is representing the cost of a hamburger}\\\\\text{We know that from the question that the cost of a pizza slice}\\\text{is represented as "p", and the hamburger costs 3 more dollars}\\\text{than a pizza slice.}\\\\\text{So you're adding 3 dollars to the cost of the pizza to get the cost of a}\\ \text{hamburger}\\\\\text{Therefore, (p+3) = cost of hamburger}

<h3>Part A</h3>

<u>Factoring the area:</u>

  • 4x² + 20x + 25 =
  • (2x)² + 2*2x*5 + 5² =
  • (2x + 5)²

<u>The length of the side is:</u>

  • √(2x + 5)² =
  • 2x + 5
<h3>Part 2</h3>

<u>Factoring the area:</u>

  • 4x² − 9y²=
  • (2x)² - (3y)² =
  • (2x + 3y)(2x - 3y)

<u>The sides of the rectangle are:</u>

  • 2x + 3y and 2x - 3y

Find the mean absolute deviation for each set of data:
aivan3 [116]

Answer:

1) 1.8

2) 1.7

Step-by-step explanation:

(for part A)

Mean: 3 + 5 + 6 + 3 + 2 + 2 + 1 + 0 + 0 + 4 + 7 + 4 + 5 + 5 + 6 = 53/15 = 3.5

3.5 - 3 = 0.5

3.5 - 5 = 1.5

3.5 - 6 = 2.5

3.5 - 3 = 0.5

3.5 - 2 = 1.5

3.5 - 2 = 1.5

3.5 - 1 = 2.5

3.5 - 0 = 3.5

3.5 - 0 = 3.5

3.5 - 4 = 0.5

3.5 - 7 = 3.5

3.5 - 4 = 0.5

3.5 - 5 = 1.5

3.5 - 5 = 1.5

3.5 - 6 = 2.5

mean absolute deviation: 0.5 + 1.5 + 2.5 + 0.5 + 1.5 + 1.5 + 2.5 + 3.5 + 3.5 + 0.5 + 3.5 + 0.5 + 1.5 + 1.5 + 2.5 = 27.5/15 = 1.8

(part B)

Mean: -3 + -2 + -1  + 0 + 1 + 2 + 3 = 0/7 = 0

0 - (-3) = 3

0 - (-2) = 2

0 - (-1) = 1

0 - 0 = 0

0 - 1 = 1

0 - 2 = 2

0 - 3 = 3

mean absolute deviation: 3 + 2 + 1 + 0 + 1 + 2 + 3 = 12/7 = 1.7
