Minnie is doing a survey to find the time her classmates spend playing musical instruments. She asks the following question: Which student spends the most time playing musical instruments?

Part A: Describe the data you would expect her to collect from this question. (5 points)

Part B: Explain whether this is a statistical question. If this is not a statistical question, then modify the question to make it statistical. (5 points)

Part A) You would expect her to find numerical answers measured in minutes or hours.

Part B) This is a statistical question because the answers should be numerical and you can receive a variety of answers.

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

i think its a and d
