Answer:
The absolute value of a number means the distance from 0. -5 is 5 units away from 0. So the absolute value of that -5 is 5. You cannot have negative distance, so it has to be positive.
Step-by-step explanation:
Answer:
(-1, 4)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
10x + 6y = 14
-x - 6y = -23
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Add 2 equations together: 9x = -9
- Divide 9 on both sides: x = -1
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: -x - 6y = -23
- Substitute in <em>x</em>: -(-1) - 6y = -23
- Multiply: 1 - 6y = -23
- Subtract 1 on both sides: -6y = -24
- Divide -6 on both sides: y = 4

Using it's concept, it is found that the sample proportion for this population is of 0.4.
- The estimate of the <em>sample proportion for a population</em> is given by the <u>number of desired outcomes divided by the size of the sample</u>.
In this problem:
- 1,599 of those surveyed responded in favor of the park.
- The sample size is of 4,000.
Hence:

The sample proportion for this population is of 0.4.
