The statement of the question tells us that 45% of the customers getting an oil change will have their car tires rotated. Therefore:
probability of both = 0.7 x 0.45
= 0.315
= 31.5%

Answer:

64.3%

Step-by-step explanation:

You are finding a conditional probability. You divide the second percent by the first percent.

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

P(A) = 0.7

P(A and B) = 0.45

= 0.45 / 0.7

= 0.643

= 64.3%

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as ed

lord [1]

Answer:

Number of books = 4480.

Step-by-step explanation:

Given that fixed cost = $45920

Given that variable cost = $11.25 per book

Let number of books = x

then cost equation is given by 11.25x + 45920

Given that selling price of 1 book = $21.50

then selling price is given by 21.50x

Now we need to find about how many books must the publisher produce and sell so that the production costs will equal the money from sales.

So let's set both equal

21.50x = 11.25x + 45920

21.50x - 11.25x = 45920

10.25x = 45920

x = 45920/10.25

x = 4480

Hence number of books = 4480.

I need help please thanks

strojnjashka [21]

Answer:

y = 1/2x + 0

You can see the slope is rising by 1 and running (to the right) by 2. This makes the slope, or rate of change, 1/2x.

There aren`t really calculations necessary to find the rate of change, but if you need more explaining please do ask, I`m happy to help

A 9-kg of mangoes for 12$_____per kg

enot [183]

If 9kg costs 12$, then a single kg costs around 1.3$

This is done with a simple proportion

9 : 12 = 1 : X
x = 12/9
