Northlake high school has two lunch periods. students can eat their lunch in the cafeteria or on an outside patio. about 42% of students who have first lunch eat outside. compare this with the percentage of second-lunch students who eat outside. first lunch second lunch total eat outside 0.19 0.21 0.40 eat inside 0.26 0.34 0.60 total 0.45 0.55 10 | select the true statement. o a. a greater percentage of second-lunch students (45%) eat outside. o b. a smaller percentage of second-lunch students (21%) eat outside. o c. a greater percentage of second-lunch students (55%) eat outside. o d. a smaller percentage of second-lunch students (38%) eat outside.

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

step-by-step explanation:

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
