Answer:
144
Step-by-step explanation:
We will use permutations to solve this problem
There are 4 pairs each having a male and a female.
The total number of sample points is 4! = 4*3*2*1= 24
He chooses the male first then the number of sample space he is left with are 3! = 3*2*1=6
The total number of ways he can select is 4! 3! = 24 * 6= 144
Another way of finding it out is
he has 4 pairs each having a male and a female so he chooses 1st male then he would choose from this
4 female choices*3 male choices * 3 female choices *2 male choices *2 female choices *1 male choices *1 female choices *= 4*3*3*2*2*1*1= 144
The formula for calculating simple interest is
I = PRT
I = Interest
P = Principal or the amount deposited ($600)
R = Rate of Interest (1.5%)
T = Time (6 yrs)
I = (600) (1.50) (6)
Multiply the 3 factors and you will have your answer.
good luck
The perimeter is 17 the area is 160
It’s A
there is no indicator that they are the same
