Answer:
A
Step-by-step explanation:
To find this quotient, we divide each term inside the parenthesis by
. Then we simplify. So we have:

Answer choice A is correct.
"x" represents an unknown number, we know that 70% of x equals 63.
To calculate the percentage of a number you have to multiply the said number by the percentage, in this case, 70%, and divide the result by 100:
So the 70% of x can be calculated as:

You can simplify this expression by solving the division

Then the expression that shows you the relationship is

Using this expression you can determine the value of x, to do so you have to divide both sides of the equal sign by 0.7

The value of x is 90
It is a 2 out of three chance of getting a composite number because that means that it is not odd. There are 10 odd numbers between 1 and 30 (2,3,5,7,11,13,17,19,23,29) and that means that there is a 20 out of 30, or 2 out of 3 chance taht the number will be composite.
