Answer:
Number of adult tickets sold= 100
Step-by-step explanation:
Giving the following information:
Adults tickets= $15
Student tickets= $10
Number of tickets sold= 150
Total sales= $2,000
<u>First, we determine the systems of equations:</u>
15*x + 10*y= 2,000
x + y = 150
x= number of adults tickets sold
y= number of students tickets sold
<u>Now, we isolate x in one equation, and substitute it in the other one:</u>
x= 150 - y
15*(150 - y) + 10y = 2,000
2,250 - 15y + 10y = 2,000
250 = 5y
50= y
x= 150 - 50
x= 100
<u>Prove: </u>
15*100 + 10*50= 2,000
100 + 50 = 150

What is the mode of this data set? 4, 69, 84, 69, 90, 75, 94, 90, 90, 1, 5
nika2105 [10]
Answer:
90
Step-by-step explanation:
90 because it occurs most in the data set.
Step-by-step explanation:
4) x=(z-y)/2
8) b=(d)/ac
9) x=(-z+4)/y
10) a=(c-3)b
To find the hypotenuse of the triangle
you use the length of the legs
Plug it into the Pythagorean Theorem
so
is one of the legs
and
is the other leg
then
is the hypothenuse
