3. Which temperature during the week is the closest to 0? Explain how you decided this using absolute value.
Katen [24]

Answer:

The closest temperature to zero during the week is -0.5 °F because it's absolute value, 0.5, is smaller than the other numbers.

The farthest temperature from zero during the week is 5 °F because it's absolute value, 5, is the highest out of all the other numbers.

Answer: The coldest temperature would be -4 °F, because it is the farthest number on the left side of zero on the number line.15-May-2020

The warmest temperature would be 5 °F, because it is the farthest number on the right side of zero on the number line.

What is the solution to this equation?
Anettt [7]

Answer:

B. a = 5

Step-by-step explanation:

3(a - 4) + 1 = 9 - a

Distribute the 3 into the parenthesis.

3a - 12 + 1 = 9 - a

Add -12 and 1.

3a - 11 = 9 - a

Add a to both sides.

4a - 11 = 9

Add 11 to both sides.

4a = 20

Divide both sides by 4.

a = 5.

Proof:

3(a - 4) + 1 = 9 - a

Substitute variable.

3(5 - 4) + 1 = 9 - 5

Subtract inside parenthesis.

3(1) + 1 = 9 - 5

Multiply 3 and 1.

3 + 1 = 9 - 5

Add 3 and 1.

4 = 9 - 5

Subtract 5 from 9.

4 = 4.

<span><u><em>The correct answer is:</em></u>
16%.

<u><em>Explanation</em></u><span><u><em>: </em></u>
We use a z-score to answer this question.
<u>The formula for a z-score is:</u>
 z=</span></span>\frac{x-mue}{sigma}<span><span>,
where mue is the mean and sigma is the standard deviation.

<u>Using our information, we have:</u>
z=</span></span>\frac{50-42}{8} =  \frac{8}{8} = 1<span><span>.

Using a z-table, we see that the area to the left of, or less than, this score is 0.8413. We want to know how many students scored more than this, so we subtract from 1:
1-0.8413=0.1587, which rounds to 16%.</span></span>
