What are the 2 numbers when 30 is the product and -11 is the sum

MArishka [77]

the answer would be -5 and -6.

-5 + -6 = -11 and -5 * -6 = 30 because when multiplying, you cancel out the negative sign when you've got an even amount of negatives.

Christy draws 3 cards from the deck one at a time without replacement. What is the probability of selecting the cards in the ord

Inga [223]

Start with a deck of 52 cards. Draw 1 card. Probability of drawing a diamond first:

$\dfrac{\binom{13}1}{\binom{52}1}$

Now draw another single card from the deck, which now contains 51 cards. Probability of drawing a spade:

$\dfrac{\binom{13}1}{\binom{51}1}$

Draw 1 last card. The deck has 50 cards left, and 12 of these are diamonds. Probability of drawing a diamond:

$\dfrac{\binom{12}1}{\binom{50}1}$

So the probability of drawing a diamond, then a spade, then another diamond is

$\dfrac{\binom{13}1}{\binom{52}1}\cdot\dfrac{\binom{13}1}{\binom{51}1}\cdot\dfrac{\binom{12}1}{\binom{50}1}=\dfrac{13}{850}$

The formula for percent error is the absolute vale of: theoretical-experimental and the result of that divided by the theoretical so it is 120-94=26 and divide that by 120 and it is .216 so round up to .22 and then multiply by 100 which is 22 so 22%
