Answer:

  22/44

Step-by-step explanation:

The probability of black is the ratio of black cards to all cards. If the Ace and 2 are removed from each suit, there will be 11 of the 13 cards remaining. 2 suits are black, for a total of 2×11 = 22 black cards. Of course there are 4 suits altogether, for a total of 4×11 = 44 total cards. Then you have ...

  P(black) = (black cards)/(total cards)

  P(black) = 22/44

_____

You are expected to be familiar with the fact that a deck of 52 playing cards consists of 4 suits: diamonds, clubs, hearts, spades. Each suit has 13 cards, identified as Ace, 2, 3, ..., 10, Jack, Queen, King. The clubs and spades are black; the diamonds and hearts are red.

Out of 20 cookies, 3/4 are chocolate chip. How many cookies are chocolate chip?
DedPeter [7]

Answer:

<u><em>15 cookies are chocolate</em></u>

Step-by-step explanation:

Well it's actually quite easy, just think about it this way. 20/4=5 since there's a 4 as the denominator in the fraction.  Or there's many other ways to find the answer. At the end of the day, you'll get the same answer just some ways are harder especially compared to the one I did.

Since we divided 4 into 20, we know the answer to that is 5.

3/4=15 if you think about it in a certain way.

Therefore the answer is 15 since 3x5= 3/4  and both of those equal 15

<u><em>Hope this helps</em></u>

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
KonstantinChe [14]
If you interpret the question as is, the answer is in the thousands which is not listed. The last part of the question should read “the number of new cases doubled from those newly identified cases from the day prior.” It was poorly phrased lol
Day 1: 5
Day 2: 5+10
Day 3: 15+20
Day 4: 35+40
Day 5: 75+80
Day 6: 155+160
Which is 315 at the end of the 6th day

I think the food will last for 5 days. Because if you subtract 7 1/2 bags with 2 1/2 you get 5.
