Answer:
5.05*10³
Step-by-step explanation:
-
<em>Put the decimal after the first digit and drop the zeroes. To find the exponent count the number of places from the decimal to the end of the number.</em>
- 5050 = 5.05 *1000 = 5.05*10³
A = $2,861.60
I = A - P = $2,361.60
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 26.24%/100 = 0.2624 per year.
Solving our equation:
A = 500(1 + (0.2624 × 18)) = 2861.6
A = $2,861.60
The total amount accrued, principal plus interest, from simple interest on a principal of $500.00 at a rate of 26.24% per year for 18 years is $2,861.60.
Formula for finding mean:
Mean = (a1 + a2 + ... + an) / n
Mean is another word for average; average number of a data set.
Problems with steps:
---------------------------------------------------------------------------------------
1) 9, 3, 6
Average = Sum/Count
Sum = 18/6
Count = 3
2) 14, 12, 17, 9
52/4
Mean = 13
3) 15,8,10,5,7
= 45/5
Mean = 9
4) 18,19,11
= 48/3
Mean = 16
5) 4,20,16,4
= 44/4
Mean = 11
6) 12,11,12,20,15
= 70/5
Mean= 14
7) 19,8,3
= 30/3
Mean = 10
8) 7,13,6,2
= 28/4
Mean = 7
9) 12,15,17,2,14
60/5
Mean = 12
10) 10,18,8
= 36/3
Mean = 12
11) 5,2 ,0,1
= 8/4
= 2
12) 3,9,5,16,7
= 40/5
Mean = 8
SOLVED !
