Answer:

n \leq -48

Step-by-step explanation:

<u>Step 1:  Convert to an expression</u>

<em>8 - 1/4 n is greater than or equal to 20</em>

8 - \frac{1}{4}n \geq 20

<u>Step 2:  Subtract 8 from both sides</u>

8 - 8 - \frac{1}{4}n \geq 20 - 8

- \frac{1}{4}n \geq 12

<u>Step 3:  Multiply both sides by -4</u>

- \frac{1}{4}n * -4 \geq 12 * -4

<em>Since we are multiplying by a negative we flip the greater than equal sign to a less than equal sign.</em>

n \leq -48

Answer:  n \leq -48

Weekly wages at a certain factory are
SSSSS [86.1K]

Answer:

2.15%

Step-by-step explanation:

If you were to get the z-score for both 500 and 550 and then get the probability of both those z-scores. After getting the probability you would subtract both probability and get your answer.

Z-score:

550-400/2=3

500-400/2=2

Probability:

3 (from the Z-table) is .9987

2 (from the Z-table) is .9772

.9987-.9772= .0215

.0215 as a percentage is 2.15%
