Well, there are 52 cards in a deck, with 4 suits. there is a Jack and queen per suit, so that is a total of 8 jacks and queens in the deck. that probability looks like 8:52 as a ratio, or 2:13 simplified. so, you are likely to draw a Jack or queen 8 out of 52 times, or 2 out of 13 times

Find the solution set. (x+7)(x+7)=0
levacccp [35]

For this case we must find the solution of the following expression:

(x + 7) (x + 7) = 0

If we isolate a term and we equate to zero, we have:

x + 7 = 0

Subtracting 7 on both sides of the equation we have:

x + 7-7 = 0-7\\x = -7

Thus, the solution of the expression is given by:

x = -7

ANswer:

x = -7
