answer keythe probability that kendra will win a card game is 23. if kendra plays 7 games what is the probability that she wins exactly 4 games? a

Answers

The probability that Kendra will win a card game is 2/3. If Kendra plays 7 games the probability that Kendra wins exactly 4 games is 0.137.

The probability of winning one game is 2/3, and the probability of losing one game is 1/3. If you want to know the likelihood of a particular number of wins, you'll need to use the binomial distribution formula.

Binomial probability refers to the probability of obtaining a certain number of successes in a set number of trials (or independent experiments).

P(x = k) = nCk x pk x (1 - p)n - k

where, nCk is the number of combinations of n things taken k at a time,

n is the number of trials,

p is the probability of success, and

k is the number of successes.

Here, n = 7, p = 2/3, and k = 4.

Using the formula, we get:

P(x = 4) = 7C4 x (2/3)4 x (1/3)3= 35 x 16/81 x 1/27= 0.137.

Hence, the probability that Kendra wins exactly 4 games is 0.137.

If P(B)=0.3,P(A∣B)=0.5,P(B ′ )=0.7, and P(A∣B ′ )=0.8, find P(B∣A).

Answers

If P(B)=0.3, P(A|B)=0.5, P(B')=0.7and P(A|B')=0.8, then the value of the probability P(B|A)= 0.2113

To find the value of P(B|A), follow these steps:

The probability of B given A can be given by the product of the probability of A given B and the probability of B, divided by the total probability of B. So, the formula for P(B|A) = P(A|B) * P(B) / [P(A|B)*P(B)+P(A|B')*P(B')]. Substituting the values, we get P(B|A) = (0.5) (0.3) / [(0.5) (0.3) + (0.8) (0.7)] ⇒P(B|A) = 0.15 / [0.15 + 0.56] ⇒P(B|A) = 0.15 / 0.71 ⇒P(B|A) = 0.2113. Therefore, P(B|A) = 0.2113.

an umbrella is made by stitching 10 triangular pieces of cloth of two different colours where each pieces measuring 48cm,48cm,and 30cm. find cost of required to make umbrella at rate of 5paisa per square cm

Answers

Answer:

Step-by-step explanation:

first we need to calculate the area of isosceles triangle having sides 48cm, 48cm and 30cm

a = 48

b= 30

Area of isosceles triangle using only sides = ½[√(a^2 − b^2 /4) × b]

= 1/2*30√( 48² - 1/4×30²)

=1/2*30√ (2304 -225)

A movie theatre sells child tickets for $7.50, adult tickets for $9.75, and student tickets for
$8. The movie theatre sold twice as many child tickets as student tickets. If a total of 191
tickets for the film were sold and the total income was $1593.50, how many of each ticket
were sold?
Find the number of child, adult, and student tickets

Answers

Answer:

child: 74 adult: 117 student: 37

Step-by-step explanation:

x=2z

x+y+z=191

7.5x+9.75y+8z=1593.5

The number of tickets sold for child is 86.

The number of tickets sold for adults is 62.

The number of tickets sold for child students is 43.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Total tickets sold = $1593.50 _____(1)

Total number of tickets sold = 191 _____(2)

Let the number of tickets sold for child = P _____(3)

Let the number of tickets sold for adults = Q _______(4)

Let the number of tickets sold for students = R ______(5)

Cost of child ticket = $7.50 ______(6)

Cost of adult tickets = $9.75 ______(7)

Cost of student tickets = $8 _______(8)

We can make equations as:

From (2), (3), (4), and (5)

P + Q + R = 191 ____(9)

From (1), (6), (7), and (8)

7.50P + 9.75Q + 8R = 1593.50 _____(10)

We have,

P = 2R putting in (9) and (10)

2R + Q + R = 191

We get,

3R + Q = 191 _____(11)

15R + 9.75Q + 8R = 1593.50

23R + 9.75Q = 1593.50 _____(12)

From (11).

Q = 191 - 3R putting in (12)

23R + 9.75 (191 - 3R) = 1593.50

23R + 1862.25 - 29.25R = 1593.50

-6.25R = -268.75

R = 43 putting in Q = 191 - 3R

We get,

Q = 191 - 3 x 43 = 191 - 129 = 62

Putting R = 43 in P = 2R

We get,

P = 2x43 = 86

We have,

P = 86, Q = 62 and R = 43

Thus,

The number of tickets sold for child is 86.

The number of tickets sold for adults is 62.

The number of tickets sold for child students is 43.

you are standing feet away from a five-story building in los angeles, looking up at its rooftop. your eyes are approximately five feet above the ground. in the distance you can see the billboard on top of your hotel, but the hotel building is completely obscured by the building in front of you. if your hotel is stories tall and the average story is feet high, how far away from your hotel are you?

Answers

If your hotel is stories tall and the average story is feet high, the distance is 69 feet.

How to find the distance?

We can solve this problem using similar triangles. Let's call the distance between you and your hotel "x".

First, we need to determine the height of the building in front of you. Since we know it is five stories tall, and the average story is 10 feet high, its total height is 5 * 10 = 50 feet.

Now, we can use the similar triangles formed by the buildings and your line of sight to set up a proportion:

x / (h + 50) = 60 / h

where "h" is the height of the five-story building, and "h + 50" is the total height of the building and its billboard.

We can cross-multiply to get:

x * h = 60 * (h + 50)

Expanding the right side, we get:

x * h = 60h + 3000

Subtracting 60h from both sides, we get:

x * h - 60h = 3000

Factoring out the h, we get:

h * (x - 60) = 3000

Dividing both sides by h, we get:

x - 60 = 3000 / h

Substituting in the known values, we get:

x - 60 = 3000 / (10 * 32)

Simplifying, we get:

x - 60 = 9.375

Adding 60 to both sides, we get:

x = 69.375

x = 69 feet

Therefore, you are approximately 69 feet away from your hotel.

The ratio a: bis 5:7.
The ratio b c is 7: 11.
What is the ratio a: b c in its simplest form?

Answers

If ratio a: bis 5:7 and the ratio b:c is 7: 11 then the simplest form of ratio a : b : c is 35 : 49 : 77.

Given that ratio a: b is 5:7.

The ratio b :c is 7: 11.

We have to find the ratio a: b c in its simplest form.

To simplify the ratio a : b : c, we can combine the ratios by multiplying the corresponding terms:

a : b : c = (5×7) : (7 × 7) : (7 × 11)

The total side area of the figure is 72.8 square inches and the volume is 32 cubic inches.

To solve this, first lets calculate the area of one of the rectangular sides of the object:

Since it's a rectagle of base 2' and height 7', the area is:

$2^{\prime}\cdot7^{\prime}^{}=14in^2$

There are 4 side like this, so we need to multiply it by 4:

$14in^2\cdot4=56in^2$

Next we can calculate the area of the square base. It's a square of side 2', then:

$(2^{\prime})^2=4in^2$

Finally, we need to calculate the area of the piramid on top. Let's find out the area of each triangle.

SInce s = 3.2' is the slant height of the pyramid, that's the height of the triangle, and the base is the same as the whole object: 2'

Then we can use the formula for the area of a triangle:

$A=\frac{h\cdot b}{2}$

Thus:

$\frac{3.2^{\prime}\cdot2^{\prime}}{2}=3.2in^2$

Before add all, we calculated the area of just one triangle, since there is 4 in the object, we need to multiply by 4:

$3.2in^2\cdot4=12.8in^2$

And now we can add all:

$56in^2+4in^2+12.8in^2=72.8in^2$

Now for the volume, we can calculate first the volume of the pyramid:

$Volume\text{ of a pyramid=}\frac{b^2h}{3}$

The base of the pyramid is 2' and the height is 3', then:

$\frac{(2in)^2\cdot3in}{3}=4in^3$

For the rectangular prism, we need to multiply the base times the width times the height.

$7^{\prime}\cdot2^{\prime}\cdot2^{\prime}=28in^3$

Added:

$23in^3+4in^3=32in^3$

Then the final answer is 72.8 square inches for the total area and 32 cubic inches for the total volume

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

If a point A(x, y) is rotated 90° counterclockwise, the new point is at A'(-y, x).

If a point A(x, y) is rotated 90° clockwise, the new point is at A'(y, -x).

If a point A(x, y) is rotated 180° counterclockwise, the new point is at A'(-x, -y).

If a point A(x, y) is rotated 270° counterclockwise, the new point is at A'(y, -x).
