Answer: The amount of money in his account after 4 years = $7,658.73
Step-by-step explanation:
If interest is compounded annually, then formula to compute amount :
, where P+ principal value, r= rate of interest, n= time ( in years).
As per given,
P= $6700 , r = 3.4% =0.034, n =4

Hence, the amount of money in his account after 4 years = $7,658.73
Answer:
3 1/2
Step-by-step explanation:
4 1 3
_ - _ = _
6 6 6
Then we simplify. 3 3 1
_ ÷ = _
6 3 2
Then just add your 3 and there 3 1/2 is your asnwer
Answer:
The second step because she distributed within the parentheses without adding the negative sign to 13
Answer: (D) 16%
Step-by-step explanation:
Binomial probability formula :-
, where n is the sample size , p is population proportion and P(x) is the probability of getting success in x trial.
Given : The proportion of students in College are near-sighted : p= 0.28
Sample size : n= 20
Then, the the probability that in a randomly chosen group of 20 College students, exactly 4 are near-sighted is given by :_

Hence, the probability that in a randomly chosen group of 20 College students, exactly 4 are near-sighted is closest to 16%.
