Step-by-step explanation:
<u>Step 1: Define</u>
3 - 4r ≥ 15
<u>Step 2: Solve for </u><em><u>r</u></em>
- [Subtraction Property of Equality] Subtract 3 on both sides: -4r ≥ 12
- [Division Property of Equality] Divide -4 on both sides: r ≤ -3
<u>Step 3: Compare</u>
- Substitute in <em>r</em>: -3 ≤ -3
This is true. -3 is less than <em>or equal to</em> -3.
To calculate the mean of a set of numbers and them all together and divide by the amount of numbers.
Example:
Find the mean of 12, 25, 36.
12 + 25 + 36 = 73
73 / 3 = 24.33
Our mean is 24.33.
