Answer:
1/2x-3=141
so first add 3 from both sides:
1/2x=141+3
1/2x=144
next divide is 1/2 on both sides
x=144/(1/2)
x=288
Answer: 8 to the -1 power
Step-by-step explanation:
In the spreadsheet, you get 1 for the mean and 0 for the MAD.
The mean of the dog washing time is 17, and the MAD is 5.5.
To find the mean, add all of the data points together and divide by 9, the number of data points:
15+20+10+18+25+10+12+30+13 = 153/9 = 17
To find the MAD, first find the difference between each data point and the mean; take the absolute value; then average these together.
|15-17|=2
|20-17|=3
|10-17|=7
|18-17|=1
|25-17|=8
|10-17|=7
|12-17|=5
|30-17|=13
|13-17|=4
2+3+7+1+8+7+5+13+4=50/9=5.5

Answer:
$10.94
Step-by-step explanation:
In the given formula, T is in years. 3 months is 3/12 years, so your interest is ...
I = PRT
I = $500×0.0875×1/4 = $10.9375 ≈ $10.94
$10.94 is the interest paid on the loan.
