Answer:

The answer is "H_0:\mu \geq 50.1\ \ and \ \ H_0: \mu \geq 50.1"

Step-by-step explanation:

An initial random selection of mail-order physicians representing firm A worked an average of 50.1 hours per week. My goal is to reject the Null Hypothesis since it is employed to make no difference. In this case,H_0 =\mu \geq50.1

Medical insurance changes are attributed to reducing the average workweek. New medical coverage is claimed to be have reduced your average workday after the government change. H_1: \mu

Compute the following products.<br> (4x+5)(4x−5)<br><br> (4x+5)2
bearhunter [10]
(4x+5)(4x-5) is equal to 16x^2+20x-20x-25
The positive and negative 20x cancel out
Leaving you with: 16x^2 - 25
[S/N this is a pattern that shows up a decent amount. Whenever you have something that looks like (x^2-y^2) it factors out to (x+y)(x-y). It might be helpful to remember]

The next one, (4x+5)2, just follows the distributive property. Multiply both components within the parentheses bye the coefficient of 2: 8x+10

This is a two-step equation. Steps: first add or subtract, then divide or multiply. 1. 5x - 7 = 48 2. 7n - 2 = 54 3. -4y + 7 = -
Bumek [7]

1. 5x - 7 = 48

5x = 48 + 7 = 55

x = 55/5 = 11

2. 7n - 2 = 54

7n = 54 + 2 = 56

n = 56 / 7 = 8

3. -4y + 7 = -21

-4y = -21 - 7 = -28

y = -28 / -4 = 7

4. x/2 + 5 = 12

x/2 = 12 - 5 = 7

x = 7 * 2 = 14

5. x/3 - 7 = 13

x/3 = 13 + 7 = 20

x = 20 * 3 = 60

6. -7 - 2 = 33 <- did you type this wrong?

-7x - 2 = 33

-7x = 33 + 2

-7x = 35

x = 5

7. -3x - 8 = -41

-3x = -41 + 8 = -33

x = -33 / -3 = 11

8. 3n - 7 = 35

3n = 35 + 7 = 42

n = 42 / 3 = 14

9. 7y + 9 = -47

7y = -47 - 9 = -56

y = -56 / 7 = -8

10. -8x + 4 = 68

-8x = 68 - 4 = 64

x = 64 / -8 = -8

11. 4n - 7 = -43

4n = -43 + 7 = -36

n = -36 / 4 = -9

12. 5x - 7 = 108

5x = 108 + 7 = 115

x = 115 / 5 = 23

13. 8 - 5w = -37

-5w = -37 - 8 = -45

w = -45 / -5 = 9

14. 42 = 18 + 4n

4n = 42 - 18 = 24

n = 24 / 4 = 6

15. 70 - 6x = 40

-6x = 40 - 70 = -30

x = -30 / -6 = 5
