Answer:
The area 2730 possible arrangements of first, second, and third place.
Step-by-step explanation:
The order in which the students finish is important. For example A, B and C is a different finishing order(outcome) than B, A and C. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
In this question:
3 from a set of 15. So
The area 2730 possible arrangements of first, second, and third place.
6x=120-5y -> x=20-5/6*y -> 7(20-5/6*y) + 11y =202 -> 140-35/6*y + 11y = 202 -> 140+31/6*y=202 -> 31/6*y = 62 -> y = 12.
Answer:
84
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Firstly,
≤ or ≥ means closed circle, and
< or > means open circle
Now, let's solve the compound inequality:
x - 1 ≤ 7
x ≤ 8
and
2x ≥ 22
x ≥ 11
This solution means "everything left of 8 (inclusive and closed circle)" and "everything right of 11 (inclusive and closed circle)"
Looking at the choices, D is right.
