= (a-5).(a+3)
= a²+3a-5a-15
= a²-2a-15
Picture cards are Jacks, queens and Kings. There are 4 of each for a total of 12 picture cards.
52-12 = 40 non picture cards.
Probability of being dealt a non picture card would be 40/52
The probability of not being dealt a non picture card would be 1 - 40/52 = 12/52 = 3/13
Answer: 3/13
<span>137.5 because first you divide 110 by 80 and then mupilty the answer by 100

For this question, the time given confuses me. I know the rate of return is just total return divided by divided by investment, Assuming that Matt received the $400 in dividends as cash payouts, and they weren't reinvested into buying shares of the stock, then his total return over two years was $500, Now, if Matt's dividends were reinvested into the stock - and if you have a 401(k) or IRA, that's what usually happens - then his ROI would have been only 6% because he only made a profit of $100 on an investment of $1500. Note: In the real world, in current market conditions, Matt probably would have got about a 5% return on a good stock, and Bella would have received about 0.05% on a savings account.
hope this helped you ;)
