The time it will take before your investment is worth $6000 = 7 years
<h3>Calculation of simple interest </h3>
The amount of money invested per month = $150
Therefore the amount principally invested yearly;
= 12 × 150 = $1,800
Simple interest = $6000
Rate = 4%
Time = ?
Using the formula for Simple interest (SI)= P×T×R/100
Make T the subject of formula,
T = SI × 100/P×R
T = $6000×100/1800×4
T = 600000/7200
T= 83 months/ 12 = 7 years

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 :
100
explanation: those two angles are supplementary which add up to be 180.
