Graph StartFraction (x minus 4) squared Over 4 EndFraction + StartFraction y squared Over 9 EndFraction = 1. The answer is C on Edge 2021

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

114 plus 113 times 2 and 114 times 3

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
