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.

Mekhanik [1.2K]
1) suppose for purposes of calculation that the cake <span>is </span><span>inscribed in a square</span> of 8 by 8
the area of 1 cake=8*8=64 in²
the rectangular table area=576 in²-----> I assume square table 24 in x 24 in
576/64= 9----------- > Sue has baked 9 cakes

if just 1 <span>carrot cake
</span>then
(9-1)=8 ---------->  <span>coffee cakes and lemon cakes
we know that </span><span>equal numbers of coffee cakes and lemon cakes
</span>therefore
coffee cakes=8/2=4
lemon cakes=4
carrot cake=1

the answer part 1) is
<span>the dimensions of the table are 24 in x 24 in
</span>the answer part 2) is
Sue has baked 9 cakes
coffee cakes=4
lemon cakes=4
carrot cake=1

part 3) distribution of the cakes in the table 24  in x 24 in

Help and explain pls
Delvig [45]
Answer:

Let’s rewrite both expressions first

y=3/2x+3

-3x+2y=6

The first expression is already plotted on the graph, so we only need to work on the second one.

Let’s turn the second equation into slope-intercept form. We can later use this to graph.

-3x+2y=6

*add 3x on both sides*

-3x+2y=6
+3x +3x
__________
2y=3x+6

*divide each number by 2*

2y=3x+6

2y/2=3x/2+6/2

y=3/2x+3

Since this is the same equation as the one graphed, it means there are an infinite number of solutions. If one were to graph this, the points would be the same as the original.

Hope this helps comment below for more questions :)
