Answer:

1. 5.25 - 5= 0.25

2. 5.5 - 4 = 1.5

Step-by-step explanation:

<h3>Find the mean: </h3>
  1. Add all values
  2. Divide by how many numbers there are

Last week:

2 + 3 + 3 + 3 + 4 + 4 + 7 + 7 + 7 + 7 + 8 + 8 = 63

63/12 = 5.25

This week:

2 + 2 + 2 + 3 + 3 + 4 + 4 + 6 + 8 + 8 + 9 + 9 = 60

60/12 = 5

<h3>Last week mean - This week mean: </h3>

Mean of strikes last week - Mean of strikes this week =

5.25 - 5 = 0.25

<h3>Find the Median:  </h3>
  1. Put all values in order
  2. Find the middle value  (If there are two numbers in the middle then find the mean of the two values)

Last week:

2 3 3 3 4 <u>4 7</u> 7 7 7 8 8

4 + 7 = 11

11/ 2 = 5.5

This week:

2  2  2  3  3  <u>4  4 </u> 6  8  8  9  9

4 + 4 = 8

8/2 = 4

<h3>Last week median - this week median: </h3>

5.5 - 4 = 1.5

If the solution to y=4x+3 is (4,16) what would the steps needed to get (4,16) be?
Ainat [17]
<span>Simplifying x4 = 16
 Solving x4 = 16
 Solving for variable 'x'.
  Move all terms containing x to the left, all other terms to the right.
Simplifying x4 = 16
 Reorder the terms: -16 + x4 = 16 + -16
 Combine like terms: 16 + -16 = 0 -16 + x4 = 0
 Factor a difference between two squares. (4 + x2)(-4 + x2) = 0
 Factor a difference between two squares. (4 + x2)((2 + x)(-2 + x)) = 0
Subproblem 1

Set the factor '(4 + x2)' equal to zero and attempt to solve:
 Simplifying 4 + x2 = 0 Solving 4 + x2 = 0
 Move all terms containing x to the left, all other terms to the right.
 Add '-4' to each side of the equation. 4 + -4 + x2 = 0 + -4
 Combine like terms: 4 + -4 = 0 0 + x2 = 0 + -4 x2 = 0 + -4
 Combine like terms: 0 + -4 = -4 x2 = -4
 Simplifying x2 = -4
The solution to this equation could not be determined.
 This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(2 + x)' equal to zero and attempt to solve:
 Simplifying 2 + x = 0 Solving 2 + x = 0
 Move all terms containing x to the left, all other terms to the right.
 Add '-2' to each side of the equation. 2 + -2 + x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + x = 0 + -2 x = 0 + -2
 Combine like terms: 0 + -2 = -2 x = -2 Simplifying x = -2

Sub-problem 3

Set the factor '(-2 + x)' equal to zero and attempt to solve:
 Simplifying -2 + x = 0 Solving -2 + x = 0
 Move all terms containing x to the left, all other terms to the right.
 Add '2' to each side of the equation. -2 + 2 + x = 0 + 2
 Combine like terms: -2 + 2 = 0 0 + x = 0 + 2 x = 0 + 2
 Combine like terms: 0 + 2 = 2 x = 2 Simplifying x = 2Solutionx = {-2, 2}</span>
