Answer:
a) 66
b) 45
Step-by-step explanation:
We have 12 horses and after the first race 2 of them have to be eliminated
that condition is equal to consider that 10 horses will be available for the second race.
The number of possiblities we have for the first race is the combination of 12 horses in group of 10
C¹²₁₀ = 12!/ (2!)* (12-2)! = 12*11/2 = 66
For the second race
C¹⁰₈ = 10! / 8! * (10-8)! = 10*9/ 2 = 45
Answer:This is approximately 3.2 gallons. So the coordinate on this line would be (3.2, 12).
Step-by-step explanation: If gas costs $3.75 per gallon and Berto has $12, then he can purchase 12/3.75 gallons. This is approximately 3.2 gallons. So the coordinate on this line would be (3.2, 12).
Answer:
-38/4, -2 38/4, -4 38/4, -6 38/4
Step-by-step explanation:
x+(x+2)+(x+4)+(x+6) = -26
4x+12=-26
4x= -38
x=-38/4
