Answer:
James invested $160,000
Step-by-step explanation:
- In total, they needed $480,000 to start the business
- 1:2 ratio means one of them payed double the amount than the other
so the expression would be,
2x + x = 480,000
Let x represent how much they each need to invest
the expression can be simplified to,
3x = 480,000
now you need to get x alone, this would be done be dividing both sides by 3
James invest $160,000
Michael invest $160,000 x 2 = $320,000
and if you add them together, you get the total amount
$320,000 + $160,000 = $480,000

Answer:
Probability that one of them is mathematics and other two are either physics or history books = 0.51
Step-by-step explanation:
Given - A student needs to select 3 books from 3 different mathematics, 3 different physics and 1 history books.
To find - What is the probability one of them is mathematics and other two are either physics or history books ?
Solution -
Given that,
A student needs to select 3 books from 3 different mathematics, 3 different physics and 1 history books.
So,
Total number of books = 3 + 3 + 1 = 7
The student has to select 3 books
So, Total number of ways = = 35
So,
Probability that one of them is mathematics and other two are either physics or history books is -
=
=
=
= 0.51
⇒Probability that one of them is mathematics and other two are either physics or history books = 0.51
