Answer: $\textsf{n = -11}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{-19 = -8 + n}$

Find: $\textsf{Solve for n}$

Solution: In order to solve for n we need to add 8 to both sides which would cancel -8 on the right side and isolate n giving us the value of n.

<u>Add 8 to both sides</u>

$\textsf{-19 + 8 = -8 + 8 + n}$

$\textsf{-19 + 8 = n}$

$\textsf{-11 = n}$

Therefore, the final answer would be that n is equal to -11.

Suppose the linear regression line y = 2.009x - 37.131 predicts a pizza

VARVARA [1.3K]

Answer:

Pizza parlor's profit = $515.344

Step-by-step explanation:

Given that:

Linear regression line for pizza parlor's profit

y = 2.009x - 37.131

x represents the number of pizzas sold

y represent the profit in dollars

Profit for 275 pizzas

Putting x = 275 in given equation

y = 2.009(275) - 37.131

y = 552.475 - 37.131

y = 515.344

Hence,

Pizza parlor's profit = $515.344
