P(B | A) = probability of B given A

P(B | A) = P(B and A) / P(A)

thus

P(new oil filter | oil change) = P(both) / P(oil change)

= 0.14 / 0.25

(b) = 0.14 / 0.4

1. What is the area of a circle with a diameter of 3.4 cm? Round your answer to the nearest tenth. (use 3.14 for pi)

Brilliant_brown [7]

1. The area of a circle is
$a = \pi {r}^{2}$
$\pi = 3.14 \\ r = \frac{3.4}{2} = 1.7$
$a = (3.14) {(1.7)}^{2} \\ = 9.0746$
The area is 9.07 cm^2.

2. The volume of a cube is
$v = {s}^{3}$
$s = 4.5$
$v = {(4.5)}^{3} \\ = 91.125$
The volume is 91.125 m^3

Granite counter tops cost $40 for every square foot. The base pay to install the counter top is $750. Set up a Linear Model repr

garri49 [273]

Answer: y = 40x + 750

Step-by-step explanation:

Linear model;

y = mx + c

y is the total cost of buying granite counter tops for a certain number of square foot as well as the cost to install the counter top.

m is the cost of granite counter tops per square foot which is $40 in this case.

x is the number of square feet required.

c is the base pay for the installation of the counter top which is $750

Linear model will therefore look like this;

y = 40x + 750

To test it. Assume you want enough granite tops for 10 square feet. How much would it cost;

= 40 (10) + 750

= $1,150
