At Kenner Country Club, 45% of the members swim. If 3 people are selected at random, what is the probability that all three will say they swim at the club?
Answers
Step-by-step explanation:
so, we pick the first one. the probability this person swims is 0.45.
if yes, then we pick the second one. this one has also a probability of swimming of 0.45.
combined with the probability of the first one being a swimmer this is now 0.45×0.45.
the same with the third pick.
and we have the probability that all 3 swim of
0.45×0.45×0.45 = 0.45³ = 0.091125
that is rounded about 0.09 or 9%.

Nigerian Savings Bank pays interest at 9½% per annum compounded yearly. What is the amount if a person saves:
a N 5000 for 2 years
b N10 000 for 4 years
c N28 000 for 3 years?
Answers
Answer:
a) N5995.13
b) N14376.61
c) N36762.11
Step-by-step explanation:
For repetitive calculations, I like to use a spreadsheet or graphing calculator. __
The formula for the amount is ...
A = P(1 +r)^t . . . . . . where principal P is invested for t years at rate r compounded annually
a)The principal being invested is P = 5000. The interest rate is r = 9.5% = 0.095, and the time is t = 2 years. Putting these values into the formula gives ...
A = 5000(1 +0.095)^2
= 5000(1.199025) = 5995.125
This rounds to an account balance after 2 years of N5995.13.
The calculations for the other amounts and time periods are done the same way, but for different values of P and t. You can do these calculations by hand, but it is generally much easier to use a calculator, spreadsheet, or other tool.
The attachment shows use of a tool that lets a function be defined that takes P and t as arguments. It is shown as being evaluated for the different values of P and t in this problem.
b)A = N10,000(1 +0.095)^4 = N10,000(1.43766095) = N14376.6095
This rounds to an account balance after 4 years of N14376.61.
c)A = N28000(1.095)^3 ≈ N36762.11

Sarah can make a lemonade drink by mixing 3 cups of lemonade powder with 7 cups of water are necessary to make five lemonade drinks
Answers
Let’s also say that one cup of lemonade is (L)
Since you need 3 cups of (p) and 7 cups of (w) to make 1 of (L), the equation would be f(L) = 3p + 7w
The (L) would be input of how many cups you need
So if you need 5 cups, use 5 as your input
F(5) =3(5)+7(5)
3x5=15
7x5=35
You need 15 cups of Lemonade powder
And 35 cups of water

I have attempted this and keep on getting about -0.28, but that is not an option.
Answers
If
[tex]\dfrac{dh}{dt} = -\sqrt{5h} = -\sqrt{5} \cdot h^{\frac12}[/tex]
then its derivative, using the power rule, is
[tex]\dfrac{d^2h}{dt^2} = -\sqrt{5} \cdot \dfrac12 h^{1-\frac12} = -\dfrac{\sqrt5}2 h^{-\frac12} = -\dfrac{\sqrt5}{2\sqrt h} = -\sqrt{\dfrac{5}{4h}}[/tex]
At h = 16, the second derivative has a value of
[tex]-\sqrt{\dfrac{5}{4\cdot16}} = -\sqrt{\dfrac{5}{64}} = -\dfrac{\sqrt5}{8} \approx -0.279508[/tex]
