A law firm has eleven male and ten female lawyers. A committee of five, two male lawyers and three female lawyers, is to be chos

4vir4ik [10]

Making sellection of a smaller group from a larger group is doe by combinations.
Here, two male lawyers are to be chosen from eleven male lawyers and three female lawyers are to be chosen from ten female lawyers.

The numbers of ways to choose r objects from n objects is given by
$^nC_r= \frac{n!}{(n-r)!r!}$

Thus,
$^{11}C_2= \frac{11!}{(11-2)!\times2!} = \frac{11!}{9!\times2!} = \frac{11\times10\times9!}{9!\times2\times1} =11\times5=55$

Also,
$^{10}C_3= \frac{10!}{(10-3)!\times3!} = \frac{10!}{7!\times3!} = \frac{10\times9\times8\times7!}{7!\times3\times2\times1} =10\times4\times3=120$

Therefore, possible number of committes = 55 x 120 = 6,600 committes.

Suppose that you have just graduated with $30,000 in student loan debt, at 9% annual interest, compounded monthly. You must make

kolbaska11 [484]

Answer:

Step-by-step explanation:

Principal amount = 30,000

I = 9% is compounded monthly ⇒ 0.09/12 = 0.0075

n= 10 years ⇒ 10* 12 = 120 periods

Formula for decreasing annuity payments is R =[ I/[1 - (1+I)^(-n)]] * P

R = 0.0075/[1 - 1.0075^(-120)] * 30,000 = $380, amount of each payment

Total amount paid is = 380*12*10 = 45600

Interest paid = Total amount - loan amount = 45600 - 30000 = 15600
