Answer:

Step-by-step explanation:

A quadrilateral inscribed in a circle has its opposite angles adding up to 180°

<NOP + <M = 180

4x+8x-24 = 180

12x = 180+24

12x = 204

Dividing both sides by 12

x = 17

<NOP = 4(17)

= 68°

On monday marco practiced the piano for 7/10 hour. On Tuesday he practiced for 1 1/4 hours each day write a question that involv

Fantom [35]

Step-by-step explanation:

Since we have given that

Number of hour Marco practiced the piano on Monday is given by

$\frac{7}{10}$

Number of hours Marco practiced the piano on Tuesday is given by

$1\frac{1}{4}=\frac{5}{4}\ hours$

1) For Adding :

Total number of hours he practiced on both Monday and Tuesday will be

$\frac{7}{10}+\frac{5}{4}\\\\=\frac{14+25}{20}\\\\=\frac{39}{20}\ hours$

2) For Subtraction,

Number of hour he practiced more on Tuesday than on Monday will be

$\frac{5}{4}-\frac{7}{10}\\\\=\frac{25-14}{20}\\\\=\frac{9}{20}\ hours$

You'd multiply 8 by 4 to get 32, and then add 2 to get 34, which is the mans age. I hope this helps!

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.
