Answer:
$750.
Step-by-step explanation:
Let x represent the number of pizzas sold, and y represent the pizza parlor's profits in dollars.
We have been given the linear regression line
, which predicts a pizza parlor's profits based on the number of pizzas sold.
To find the profit of pizza parlor when it sells 275 pizzas, we will substitute x=275 in our given equation.
![y=3.009*275-77.131](https://tex.z-dn.net/?f=y%3D3.009%2A275-77.131)
![y=827.475-77.131](https://tex.z-dn.net/?f=y%3D827.475-77.131)
![y=750.344\approx 750](https://tex.z-dn.net/?f=y%3D750.344%5Capprox%20750)
Therefore, the pizza parlor will make a profit of $750, if it sells 275 pizzas.
Answer:
(1, 3)
Step-by-step explanation:
Given coordinates of 2 endpoints, G(-2, 5) and H(4, 1), midpoint of AB is calculated as shown below:
Midpoint (M) of GH, for G(-2, 5) and H(4, 1) is given as:
![M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})](https://tex.z-dn.net/?f=%20M%28%5Cfrac%7Bx_1%20%2B%20x_2%7D%7B2%7D%2C%20%5Cfrac%7By_1%20%2B%20y_2%7D%7B2%7D%29%20)
Let ![G(-2, 5) = (x_1, y_1)](https://tex.z-dn.net/?f=%20G%28-2%2C%205%29%20%3D%20%28x_1%2C%20y_1%29%20)
![H(4, 1) = (x_2, y_2)](https://tex.z-dn.net/?f=%20H%284%2C%201%29%20%3D%20%28x_2%2C%20y_2%29%20)
Thus:
![M(\frac{-2 + 4}{2}, \frac{5 + 1}{2})](https://tex.z-dn.net/?f=%20M%28%5Cfrac%7B-2%20%2B%204%7D%7B2%7D%2C%20%5Cfrac%7B5%20%2B%201%7D%7B2%7D%29%20)
![M(\frac{2}{2}, \frac{6}{2})](https://tex.z-dn.net/?f=%20M%28%5Cfrac%7B2%7D%7B2%7D%2C%20%5Cfrac%7B6%7D%7B2%7D%29%20)
![M(1, 3)](https://tex.z-dn.net/?f=%20M%281%2C%203%29%20)
Coordinates of the midpoint of GH = (1, 3).
Answer:
10 ÷ 16
Step-by-step explanation:
The computation is shown below
Given that
Paul required to buy 5 by 8 pound of peanuts
And, the scale at the store is in sixteenths
So, the measure that should be equivalent is
Here the denominator should be 16 so it should be multiplied by 2
= 5 ÷ 8 × 2 ÷ 2
= 10 ÷ 16
A=3 and B=1. comment if you would like me to explain how I did it.
