There are no real solutions to the problem.
The discriminant is -96 when the discriminant is a negative number it has no real solutions, only imaginary ones.
It would be a 4 in 28 probability (or 1 in 7 if you simplify)
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
first you add up all the number of combs together which gives you 28 combs total
the there were 4 blue combs out of the 28
so the probability it 4 in 28 or 1 in 7
The answer to this question is D
Answer:
72
Step-by-step explanation:
number of children tickets purchased = c
number of adult tickets purchased = a
c+a= 164
(5.10 x c) + (9.40 x a) = 1232
c + a - a = 164 - a
c = 164 -a
(5.10 x (164-a)) + (9.40 x a) = 1232
836.40 - 5.10a + 9.40a = 1232
836.40 + 4.30a = 1232
4.30a = 395.60
4.30a/4.30 = 395.60/4.30
a = 92
c = 164 - 92
c = 72
The answer is 24. To get from one term to the next, you have to find the difference. To get from 52 to 45, you minus 7. It is the same with the other terms. So 31 - 7 = 24
