Answer:
1. $2,950.62
2. $93.75
Step-by-step explanation:
Ann took out a loan of = $12,000
At an interest rate of = 5.65%
Time = 4 years
Formula of compound interest = 
= 
= 
= 12,000 × 1.24588514
Interest = Amount - principal amount
= $14,950.62 - 12,000
= $2,950.62
Amount that Dan borrowed = $1,250
rate of interest = 5%
Time = 18 months or 1.5 years
Formula of simple interest = P(1+rt)
= 1250(1+(0.05 × 1.5))
= 1250(1+0.075)
= 1250 × 1.075
= 1343.75
Interest = Amount - principal
I = 1343.75 - 1250
= $93.75
Answer:
-0.24 ; 0.71
Step-by-step explanation:
Given that :
Mean number of siblings (m) = 3.76
Standard deviation (s) = 3.18
Z score associated with 3 siblings
x = 3
Using the relation :
Zscore = (x - m) / s
Zscore = (3 - 3.76) / 3.18
Zscore = - 0.76 / 3.18
Zscore = −0.238993
Zscore = - 0.24
2.) proportion of respondents with more than 2 siblings
Using the z probability calculator :
X > 2
Obtain the standardized score :
Zscore = (x - m) / s
Zscore = (2 - 3.76) / 3.18
Zscore = - 1.76 / 3.18
Zscore = −0.5534591
Zscore = - 0.55
Using the z table :
P(Z ≥ - 0.55) = 1 - p(Z ≤ - 0.55) ; p(Z ≤ - 0.55) = 0.2912
1 - p(Z ≤ - 0.55) = 1 - 0.2912 = 0.7088 = 0.71
