Answer:
C, F.
Step-by-step explanation:
All angle measures are preserved in a dilation. And if all angle measures are preserved, it makes the triangles similar by the AA similarity theorem.
X+y=1770
9x+4y=14680
x=1770-y
9(1770-y)+4y=14680
15930-9y+4y=14680
-5y=-1250
5y=1250
y=1250/5
y=250
children attended=250
First you have to find out the cost of the ticket. To do so you have to Divide 15 and 6. Which equals $2.50. So each ticket is $2.50 dollars. Now you have to multiple 2.50 times 9. which equals 22.5. So your total answer is $22.50 dollars
The mean is 30,000
The standard deviation is 10,893.42
