(Q means Question. Q1, Q2, and Q3 are the questions I need help on. If anyone has the answer to all three of those questions, thanks)

ACT mathmatics score for a particular year are normally distributed with a mean of 27 and a standard deviation of 2 points.

Q1. What is the probability that a randomly selected score is greater than 29 points

Q2. What percentage of student scores are between 31 and 23?

Q3.A student who scores a 31 is in the percentile

it would more likely be bald eagle because its has more in the box so about 75%.

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
