A line passes through (-1, 7) and (2,10) which equation is the equation of the line? -x y=12 -x y=8 -3x y=16 -3x y=4

notka56 [123]

Equation of a line through two points is given by y - y1 = ((y2 - y1)/(x2 - x1))(x - x1)
y - 7 = ((10 - 7)/(2 - (-1)))(x - (-1))
y - 7 = (3/(2 + 1))(x + 1)
y - 7 = 3/3 (x + 1)
y - 7 = x + 1
-x + y = 1 + 7
-x + y = 8

a packe of cards conatins 4 red and 5 black cards. a hand of 5 cards is drawn without replacment. What is the proablity of all f

Vladimir79 [104]

Answer: Our required probability is 0.3387.

Step-by-step explanation:

Since we have given that

Number of red cards = 4

Number of black cards = 5

Number of cards drawn = 5

We need to find the probability of getting exactly three black cards.

Probability of getting a black card = $\dfrac{5}{9}$

Probability of getting a red card = $\dfrac{4}{9}$

So, using "Binomial distribution", let X be the number of black cards:

$P(X=3)=^5C_3(\dfrac{5}{9})^3(\dfrac{4}{9})^2\\\\P(X=3)=0.3387$

Hence, our required probability is 0.3387.
