Answer:
The probability that a car that comes into the garage needs both an oil change and a tire rotation is 
.
Step-by-step explanation:
The conditional probability of an event <em>B</em> given that another event <em>A</em> has already occurred is:
Denote the events as follows:
<em>X</em> = cars brought in for service need an oil change
<em>Y</em> = cars brought in for service need a tire rotation
The information provided is:
Compute the value of P (X ∩ Y) as follows:
Thus, the probability that a car that comes into the garage needs both an oil change and a tire rotation is .
He will be able to buy lunch for 21 days because 58.19 divided by 2.74 is 21. 237226
For this case we have the following variables:
P = area covered by a roll of wallpaper
w = the total area of the walls
n = number of rolls to buy
We write the equation for n.
You must take into account that you can determine this amount by dividing the total area between the area covered by each roll of paper.
We have then:
Answer:
a formula that will help them determine how much wall paper they'll need to purchase is:
Answer:
11 hrs
Step-by-step explanation:
so he made 135 for 9 hrs.....thats (135/9) = $ 15 an hr
so if he made 165, he would have to work (165/15) = 11 hrs <==
It is 12 liters. 2.75 gallons is approximately 10.41 liters and 12 liters is more than 10.41 liters.
