A line passes through the point (–7, 5) and has a slope of One-half. Which is another point that the line passes through?
irina1246 [14]

Answer:

(13, 9)

Step-by-step explanation:

Make an equation for the line.

y = 0.5x + b

5 = -3.5 + b

b = 8.5

y = 0.5x + 8.5

Plug them into the equation.

(-13, 9) 9 ≠ -6.5 + 8.5

(-9, 13) 13 ≠ -4.5 + 8.5

(9, 13) 13 = 6.5 + 8.5

(13, 9) 13 ≠ 4.5 + 8.5

A poker hand consisting of 9 cards is dealt from a standard deck of 52 cards. Find the probability that the hand contains exactl
Andrew [12]

Answer: \dfrac{^{12}C_{6}\times^{40}C_3}{^{52}C_9} or  \dfrac{228}{91885} .

Step-by-step explanation:

Given : A poker hand consisting of 9 cards is dealt from a standard deck of 52 cards.

The total number of cards in a deck 52

Number of faces cards in a deck = 12

Number of cards not face cards = 40

The total number of combinations of drawing 9 cards out of 52 cards = ^{52}C_9

Now , the combination of 9 cards such that exactly 6 of them are  face cards =  ^{12}C_{6}\times^{40}C_3

Now , the probability that the hand contains exactly 6 face cards will be :-

\dfrac{^{12}C_{6}\times^{40}C_3}{^{52}C_9}

=\dfrac{\dfrac{12!}{6!6!}\times\dfrac{40!}{3!37!}}{\dfrac{52!}{9!\times43!}}\ \ [\because\ ^nC_r=\dfrac{n!}{r!(n-r)!}]\\\\=\dfrac{228}{91885}

Hence, the probability that the hand contains exactly 6 face cards. is  \dfrac{228}{91885} .
