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.
The two angles form a a straight line which is equal to 180 degrees:
Make an equation:
57 + (x +23) = 180
Simplify:
x + 80 = 180
Subtract 80 from both sides:
x = 100
Answer:
The interval notation is;
![(-\infty,4]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C4%5D)
Step-by-step explanation:
The solution set of the inequality represented on the number line is
![x\le4](https://tex.z-dn.net/?f=x%5Cle4)
The boundary 4 is inclusive in the solution set, so we use square bracket "[ ]" to show inclusion and open bracket "()" to show that, that part of the interval in not bounded.
In interval notation, we can write this as;
![(-\infty,4]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C4%5D)
