the sample would be the number polled - 50,000
the population would be all college students
Answer:
x=1/3
Step-by-step explanation:
Add x to both sides, 3x+5=6
Subtract five from both sides
3x=1
Divide both sides by 3
x=1/3
Answer:
-6
Step-by-step explanation:
(-6) squared -36=0
36-36=0
Simplify the equation as best you can and then graph it. When you have graphed it, the x-coordinate when y=0 is x.
The cost per adult ticket is $13 and the cost per children ticket is $8
Step-by-step explanation:
Let the cost of adult tickets be 'x'
Let the cost of children tickets be 'y'
2x + 3y = 50
2x = 50 - 3y
x = (50 - 3y) /2
3x + 4y = 71
[3(50-3y) /2 ]+ 4y = 71
(150 - 9y) /2 + 4y = 71
150 - 9y + 8y = 142
150 - y = 142
y = 150 - 142
y = 8
x = (50-3y) /2
x = (50-24) /2
x = 13
The cost per adult ticket is $13 and the cost per children ticket is $8
