NEED HELP ASAP 1. What was the theoretical probability of collecting a specific dinosaur, such as a Velociraptor, in a single purchase?
2. How many spins did it take before you had at least one of each dinosaur in Trial 1? Trial 2? Trial 3?
3. How does the number of spins correlate to the number of boxes of cereal that you would need to purchase?
4. What was the experimental probability for each dinosaur from Trial 1? Trial 2? Trial 3?
5. How does the experimental probability of getting each dinosaur differ from the theoretical probability? Here, you are
comparing the experimental vs. theoretical probability of getting each type of dinosaur in a single purchase. In other
words, you are determining the probability for a single event, not a compound event.
6. If someone bought eight boxes of cereal and got all eight dinosaurs, would you be surprised? Why or why not?
7. How did the experimental probabilities change between the trials?
8. What are the advantages of using a simulation versus actually buying boxes of cereal?

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
