Answer:

P(algebra, then statistics) = 7/80

Step-by-step explanation:

The total number of books is 7 + 8 + 5 = 20.

1. P(algebra, then statistics)

The probability that the first book is an algebra book is 7/20.

Carlos then replaces the book, so the total is still 20.

The probability that the second book is a statistics book is 5/20.

Therefore, the total probability is:

P(algebra, then statistics) = 7/20 × 5/20

P(algebra, then statistics) = 7/80

1: A woman buys a car making a $3,000 down payment and then agrees to make 48 monthly payments of $360. What is the total cost o

katrin [286]

Answer:

1. $20280

2. 117 h

Step-by-step explanation:

to know the value of the car we have to add all the monthly payments with the $ 3000 that she paid at the beginning

x = car value

x = $3000 + 48 * $360

x = $3000 + $17280

x = $20280

The total cost of the car is $20280

To know how many hours I work in total we have to add the hours I work in each day 5 times with the 57 hours I work the following week

x = hours that work in all

x = 5 * 12 + 57

x = 60 + 57

x = 117

work for 117 hours in all

does anybody have an easy way of finding the factors of a number without spending a long time on it? (a number like 288)

Natali [406]

There are quite a few websites that have factor lists. Also, if you can find the biggest number that goes into it, then all of the factors of that number go into it as well.
