Answer:
A. y= 2(x - 2)2 + 4
Step-by-step explanation:
vertex having an x value of 2 means the phrase in paren must be x - 2.
This eliminates B and D
vertex having a y value of 4 is of no help as the remaining two equations will result in 4 if the x term is 2
plugging in x = 3 makes y = 6 in equation A, but not in equation C where y = 10

I count n=12 observations, sorted they're
0 0 0 1 1 2 2 3 3 4 5 10
The median is the middle value, or the average of the two middle ones when we have an even number. That's (2+2)/2=2
Median: 2
The mode is the most common observation. Three friends had no pets.
Mode: 0
The range is maximum minus minimum, so 10 - 0 = 10
Range: 10
Answer: The expected value of purchasing a raffle ticket would be $0.3449.
Step-by-step explanation:
Since we have given that
Number of tickets = 5500
Number of flower arrangements = 20
Number of gift certificates = 20
So, Probability that wining $70 at flower arrangement = 
Probability that wining $25 at gift certificates =
So, Expected value of purchasing a raffle ticket would be
Hence, the expected value of purchasing a raffle ticket would be $0.3449.
