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
Substitute X or Y With 0 So It Would Be 3/5(0) +1/2y = 30
1/2y=30
Divide Get Y And Do The Same For X
Answer:
15 miles
Step-by-step explanation:
pythagorean theorem
9²+12²=x²
x=15 miles
On the line segment 
, 
depends only on 
:
Find the critical points of 
.
At this critical point, we have
Check the value of at the endpoints of the line segment.
So we have
Answer:600 x X
Step-by-step explanation:
The numerical solution to this question requires knowledge of the fuel consumption of the vehicle. However assuming that the vehicle consumes X gallon of gasoline per mile, the cost in gasoline to drive 600 miles would be 600 x X =600X
