Answer:
It will take 13 years and 66 days
Explanation:
Giving the following information:
Your savings account earns 1.72% interest.
Present value= $3,000
Final value= $3,756
To calculate the number of years, we need to use the following formula:
n= ln(FV/PV) / ln(1+i)
n= ln(3,756/3,000) / ln(1.0172)
n= 13.18 years
To be more specific= 365*0.18= 66
It will take 13 years and 66 days
The wages are quite a bit higher than industry standard. It's about 33% which is 8% higher.
Answer: 20 women
Explanation:
Making the total number of women in the club 'x', we can then do the following,
Total Number of Names in Hat, N
N = x + 10 ( total number of men)
therefore total number of names in the hat N=x+10
We need to select 3 people so sample size = 3
Using the Hypergeometric Distribution then we can then use the formula,
Expected number of women on the Committee = k * n / N
Where k is the total number
2 = x * 3 / (x + 10)
2 = 3x/(x +10)
3x = 2x +20
x = 20
There are 20 women in the club.
