Equality Properties

<u>Algebra I</u>

  • Terms/Coefficients/Degrees

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Set up equation.</em>

mAB + mBC = mAC

x + 4 + 4 = 3x + 2

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                     x + 8 = 3x + 2
  2. Isolate <em>x</em> terms:                             8 = 2x + 2
  3. Isolate <em>x </em>term:                               6 = 2x
  4. Isolate <em>x</em>:                                        3 = x
  5. Rewrite:                                         x = 3

<u>Step 3: Find AB</u>

  1. Define:                              mAB = x + 4
  2. Substitute in <em>x</em>:                 mAB = 3 + 4
  3. Add:                                  mAB = 7

Answer:

The 98% confidence interval for the mean number of hours of study time per week for all students is (20.9, 25.1).

Confidence interval:

Sample mean plus/minus the margin of error.

In this question:

        $8

---------------------- = 5 1/3 tickets

 ($1.50/ticket)

or N < 5.
