The perimeter of the triangle is : 12.6.

This result is obtain by the use of triangle perimeter formula :

$P = a+b+c\\$

Where : a is the distance between the points A and B

b is the distance between the points B and C

c is the distance between the points C and A

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.

Can anyone explain how to do this?

Aliun [14]

<h3>Answer: 85 units ^2</h3>

Step-by-step explanation:

Using the equation $a^{2} + b^{2} = c^{2}$

so $a^{2} = 35$ and $b^{2} =50$

$a^{2} + b^{2} = 85^{2}$

Two trains leave stations 288 miles apart at the same time and travel towards each other. One train travels at 95 miles per hour

erma4kov [3.2K]

95x=85x+288
You could add 288 to any side, it just shows that they're 288 miles apart.
Let's subtract 85x from both sides.
10x=288
28.8=x
It'll take 28.8 hours for the trains to meet. Let's make sure.
28.8×95
2,736
28.8×85
2,448
2,736-2,448
288
So, they'll meet up after 28.8 miles.
