The chances of her being picked are 3/26...so the chances of her not being picked are 23/26
From the given problem, I gather that there are only two groups of forces. These are:
13 lb, 35 lb, resultant force 30 lb
20 lb, 15 lb, resultant force 25 lb
We use the pythagorean theorem to determine if the three forces are grouped correctly, such that the resultant force is the hypotenuse.
Resultant Force = √(a² + b²)
So, for the first group,
30 ? √(13² + 35²)
30 ≠ 37.33
Thus, the first group does not pull at right angles to each other.
For the second group,
25 ? √(20² + 15²)
25 = 25
Thus, the second group does pull at right angles to each other.
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.
Therefore, the pizza parlor will make a profit of $750, if it sells 275 pizzas.
