Answer:

$\frac{2}{3}$

Step-by-step explanation:

Given: Total number of the students are nine. Since there are 6 in total students who likes pepperoni and olives. Therefore,

P(A or B)= $\frac{Number of students that likes pepperoni and olives}{Total number of students}$

= $\frac{6}{9}$

= $\frac{2}{3}$

What is the equation for the circle with the center (11,6) and passes through the point (17,12)

MissTica

Answer:

The answer to your question is the letter D. (x - 11)² + (y - 6)² = 72

Step-by-step explanation:

Data

Equation = ?

Center = (11, 6)

Point = (17, 12)

Process

1.- Calculate the length of the radius using the distance between two points formula.

d = $\sqrt{(x2 - x1)^{2}+ (y2 - y1)^{2}}$

x1 = 11 y1 = 6

x2 = 17 y2 = 12

-Substitution

d = $\sqrt{(17 - 11)^{2}+ (12 - 6)^{2}}$

d = $\sqrt{6^{2} + 6^{2}}$

d = $\sqrt{36 + 36}$

d = $\sqrt{72}$

radius = $\sqrt{72}$

2.- Write the equation of the formula

(x - 11)² + (y - 6)² = ( $\sqrt{72}$ )²

Result

(x - 11)² + (y - 6)² = 72

Three shipping companies want to compare the mean numbers of deliveries their drivers complete in a day.

Marianna [84]

Answer:

#1 is 10

# 2 is

6 + 7 + 8 + 9 + 10 + 10 + 10 + 12 + 14 + 14 = 100/10. The (Mean) = 10

(6- 10) + (7- 10) + (8- 10) + (9- 10) + (10- 10) + (10- 10) + (10- 10) + (12- 10) + (14- 10)

4 + 3 + 2 + 1 + 0 + 0 + 0 + 2 + 4

= 16/10 = 1 6/10

The (MAD) = 1 6/10

The function g(x) = 10.73 + 8.14(x - 1) represents the charge for parking at the airport for x number of days. Which statement b

Andrews [41]

Answer:

<h3>This function states that the first hour has a fixed cost of 10.75.</h3><h3>Then, every additional hour has an additional cost of $8.14.</h3>

Step-by-step explanation:

The given function is

$g(x)=10.75+8.14(x-1)$

The statements that best represent the formula are:

This function states that the first hour has a fixed cost of 10.75.
Then, every additional hour has an additional cost of $8.14.

You can deduct that from the formula, because $x$ represents hour, so for $x=1$ , we have

$g(0)=10.75+8.14(1-1)=10.75$

Which means 1 hour costs $10.75.

Then, for $x=2$

$g(2)=10.75+8.14(2-1)=10.75+8.14=18.89$

Which means an additional hour cost $8.14 additionally.
