Answer:
Null hypothesis : 
Alternate hypothesis : 
Step-by-step explanation:
To Find : State the hypotheses to be tested.
Solution
Mean = 72
Standard deviation = 20
N = 30
Claim : Shorney Construction Company bids on projects assuming that the mean idle time per worker is 72 or fewer minutes per day.
So, Null hypothesis : 
Alternate hypothesis : 
The value that makes the equation true is 3!
7(3) + 1 = 22

54 units²</h2><h2 />
This is a compound shape. You can split it into x shapes. See Attachment
Area of a Rectangle = L × B
L = 7
B = 6
7 × 6 = 42
<h3>42 units²</h3>
Area of a Triangle = 1/2BH
B = 6
H = 1
1/2 × 6 × 1 = 3
<h3>3 units²</h3>
Area of a Triangle = 1/2BH
B = 3
H = 2
1/2 × 3 × 2 = 3
<h3>3 units²</h3>
Area of a Triangle = 1/2BH
B = 2
H = 6
1/2 × 2 × 6 = 6
<h3>6 units²</h3><h3 /><h3>42 + 6 + 3 + 3 = 54</h3>
Answer:
11 1/9 - 3 2/3 = 7 3/9
Step-by-step explanation:
First you have to turn 2/3 into ninths which would be 6/9. Then you have to turn 1/9 into 10/9 by giving one whole and turning it into a fraction. Then you have to subtract 10/9 - 6/9 = 3/9. Finally you have to subtract the wholes 10-3= 7 then your answer would be 7 3/9
200 and 150 because 25% of 200 is 50 so subtract 50 from 200 because it is supposed to be 25% smaller
