There are total 4 outcomes
We can get:
Head, Head
Head, Tail
Tail, Head
Tail, Tail
So, tossing 2 coins, result in 4 possible outcomes which make the sample space.
So correct answer is option B
Answer:
Step-by-step explanation:
It usually works well to let a variable represent quantity of the highest-value contributor. Here, that is the quantity of adult tickets.
Let "a" represent the number of adult tickets sold. Then (324-a) is the number of admission fees for children. The total revenue is ...
5.40a +2.50(324 -a) = 1390
2.90a +810 = 1390 . . . . eliminate parentheses
2.90a = 580 . . . . . . . . . subtract 810
a = 200 . . . . . . . . . . . . . .divide by 2.90
The number of children admitted was 124; the number of adults admitted was 200.
√x²+√9y² = √36
↓
x+3y=6
x=2
and y= 1 2/3
Answer:
x < -3/2
Step-by-step explanation:
12x + 7 < -11
Subtract 7 to both sides
12x < -11 -7
= 12x < -18
Solve for x.
x < -18/12
= x < -3/2
The sum of 6(-2.1k-2) + (7k+5) is -5.6k-7
