Find that line of the data has the equation y=0.5x+1.5which statement best explains how removing the point (15,7) would affect the slope of the line of best fit

Marlene is playing Skee Ball at her favorite arcade. She wants to determine the likelihood that she'll roll a ball into each hole. So, she rolls several times and records her results in the following table.

A. On any given roll, the experimental probability that Marlene will get 30 points is 0.60.20.120.06.

B. On any given roll, Marlene is most likely to get  10000000

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

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
