Answer:
The answer is "Approximately normal".
Step-by-step explanation:
sample size
Sample size
It is because
the sampling distribution of the sample means is approximately normal.
The compound interest is given by:
A=p(1+r/100)^n
where;
A=amount
p=principle
r=rate
n=time
therefore the time taken for Felicia's money to double will be:
350=175(1+4/100)^n
350/175=1.04^n
2=1.04^n
therefore introducing natural longs we get:
ln2=nln1.04
n=(ln2)/(ln1.04)
n=17.7 years
The answer is 17.7 years
2 7/12 hours
X=101/2 - ( 3+4+1/4+2/3)
X=101/2 - 7 + (1/4+2/3)
1/4+2/3= 11/12
101/2 - 7 =3 1/5
X = 3 1/5 - 11/12 = 2 7/12
