Select 4 from 9, and 3 from 8. Multiply together.
C(9,4)*C(8,3)
=9!/(4!5!) * 8!/(3!5!)
=7056
Answer:
q=(40-7)/3 or simplified q=11
Step-by-step explanation:
So we know that the perimeter is 40 inches and one of the sides is 7 so logically we do 40-7 to get the length of the three remaining sides combined. Then to find the length q, we have to divide that answer by 3 because the three sides have the same length or (40-7)/3, which simplified is 11, so the length of the side is 11 inches and the expression is q=(40-7)/3.
Answer:
10X5 = 50 9X12 = 108
Step-by-step explanation:

The 2nd choice is appropriate.
250 shares for $ 12 per share......250 * 12 = 3000
plus the 2% commission......3000(1.02) = 3060...so the commission is $ 60
she then sells her stock (250 shares) for $ 18 a share....
250 * 18 = 4500
plus the 1% commission....4500(1.01) = 4545...so the commission is $ 45
net proceeds is the amount received by the seller after all costs and expenses are deducted...
expenses : 3000 + 60 + 45 = 3105
revenue : 4500
net proceeds = 4500 - 3105 = $ 1395 <==
