For a 2:7 ratio there would be 100 boys and 350 girls
What are the next four terms in the following arithmetic sequence? (-7), (-2), 3, 8,... A. 18, 23, 28, 33 B. 13, 18, 23, 28 C. 8

Ok..ur adding 5 each time to get the next term
so the next 4 terms are : 13, 18, 23, 28
12/42 because if you divide 24 by 2 you get 12 and divide 84 by 2 you get 42 and 4/14 because if you divide 24 and 84 by 6 you get 4 and 14
First, we must find what percent of 7,000 is 160.
To do this, let's do 160/7,000
160/7000 simplified is 4/75.
So, 4 out of every 75 CDs will be defective. If we want to find the probability of them all being affective, we must first do 71/75, because we subtracted the amount of defective CDs from the numerator.
Next week must multiply 71/75*71/75*71/75*71/75*71/75 to get the probability of 5 randomly selected ones being affective.
I got 1804229351/2373046875
If you divide this, you get 0.76030076354, so there is about a 76 percent chance of having all 5 randomly pulled be affective.
.Hope this helped! Comment if you have any questions!!!
The sum is 
<em><u>Solution:</u></em>
Given that we have to find the sum
<em><u>Given expression is:</u></em>
We have to add both the expressions
Addition of two polynomials involves combining like terms present in the two polynomials
Like terms are the terms having same variable and same exponent
From given expression,
Remove the parenthesis and add
Combine the like terms
Add the like terms
Thus the sum is
