Answer:
a) m = 3 b = 1/5
b) y = 1/2x - 3
Step-by-step explanation:
y=mx+b
Rearrange it to its 3y= 7x+15. Then divide both sides by 3 to get y=7/3x+5
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 : 
$1 = 2 weeks
-
<u>Multiply by 800:</u>
$1 x 800 = 2 x 800 weeks
$800 = 1600 weeks
-
Answer: You need <u>1600 weeks </u>to get $800
