Answer:
P = $300
r = 0.15
n = 12
$544.61 (to the nearest cent)
$524.70 (to the nearest cent)
Step-by-step explanation:
P = principal amount = $300
r = annual interest rate in decimal form = 15% = 15/100 = 0.15
n = number of times interest is compounded per unit t = 12
<u>How much she'll owe in 4 years</u>
P = 300
r = 0.15
n = 12
t = 4
= $544.61 (to the nearest cent)
<u>Yearly compounding interest rate</u>
<u>How much she'll owe in 4 years at yearly compounding interest</u>
= $524.70 (to the nearest cent)
No he is wrong because 75% more time would be spent doing homework
Answer:B
Step-by-step explanation:
Hi there!
<u>Set A has a LARGER standard deviation. </u>
A set's standard deviation is equivalent to:
σ = standard deviation
x = value
μ = mean
n = # of observations
Basically, standard deviation is calculated using how far apart EACH value is from the set's mean. If more values are FARTHER away from the mean, the standard deviation increases and vice-versa.
Set A has a GREATER RANGE and its values are farther from 13 on both sides compared to Set B which has a SMALLER RANGE and its values are closer to 13.
Therefore, Set A will have a larger standard deviation.
