The probability that a point randomly chosen in the large triangle is also in Region A will be 11/36.

What is probability?

Probability of an event is the ratio of number of favorable outcomes to the total number of outcomes.

Probability is a measure of how likely an event is going to happen.

Given is to find the probability that a point randomly chosen in the large triangle is also in Region A.

We can find the area of region A as -

Area{A} = A{Rectangle} + A{Right triangle}

Area{A} = (Length x Breadth) + (1/2 x base x height)

Area{A} = (5 x 2) + (1/2 x 1 x 2)

Area{A} = 10 + 1

Area{A} = 11 square units

Total area of the region {A + B} as -

Total Area{A + B} = 11 + (1/2 x 10 x 5)

Total Area{A + B} = 11 + 25

Total Area{A + B} = 36 square units

The probability that a point randomly chosen in the large triangle is also in Region A will be -

P{A} = (Area{A}/Total Area{A + B})

P(A) = 11/36

Therefore, the probability that a point randomly chosen in the large triangle is also in Region A will be 11/36.

Elena’s backyard is in the shape of a rectangle. She created a triangular-shaped flower bed (shown as the shaded region) to plant flowers in.



The area of the triangular flower bed is square feet. The area of her backyard that does not include the flower bed is square feet.

Answers

Answer:

b

Step-by-step explanation:

iS THE ANSWER

Area of background without flower bed = 575 feet²

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that:

Length of rectangle ground = 35 feet

Width of rectangle ground = 20 feet

Height of triangle bed = 10 feet

Base of triangle bed = 25 feet

Now, We can formulate;

Area of background without flower bed = Area of rectangle - Area of triangle

Hence, Area of background without flower bed = [l x b] - (1/2)(b)(h)

Area of background without flower bed = [35 x 20] - (1/2)(25)(10)

Area of background without flower bed = 700 - 125

Area of background without flower bed = 575 feet²

Thus, Area of background without flower bed = 575 feet²

Lara is playing a video game where she hunts for treasure, like these gems:


A sapphire is worth 5 gold coins, and a ruby is worth 8 gold coins.

On her last hunt, Lara found 17 gems, all either rubies or sapphires, and sold them for 100 coins. How many sapphires did she find?

Answers

Answer:

12 sapphires

Step-by-step explanation:

Let's call the number of sapphires x. This means the number of rubies is the total number of gems minus x, or 17-x.

# of Sapphires: x

# of Rubies:17-x

A sapphire is worth 5 (gold coins) each, and a ruby is worth 8.

We also know the total amount of money is 100 coins, so

5*x+8*(17-x)=100

5x+136-8x=100

-3x=-36

x=12

Remember:

# of Sapphires: x

# of Rubies:17-x

...so Lara found 12 sapphires and 17-12=5 rubies.

Find the mean, median, and mode(s) of the data with and without the outlier.

45, 52, 17, 63, 57, 42, 54, 58

Answers

Answer:

Mean = 48.5, Median = 53, Mode = nothing, Outlier = 17

Step-by-step explanation:

Mean: Add all the numbers (388) then divide by how many numbers (8) are there. (= 48.5)

Median: Is the middle number () so you have to order them from least to greatest (17, 42, 45, 52, 54, 57, 58, 63) and then just keep marking them off left, right, left, right... until you get to the middle. But since there are two numbers (52, 54) you have to add them (106) then you divide by 2 (53).

Mode: Is the number that shows up the most. In this case none of them do.

Outlier: The number that is farthest from the other numbers (17).

The mean, median, and mode(s) of the data Without outlier Mean is 51

Median is 53 and Mode is None

To find the mean, median, and mode(s) of the data, we can start by arranging the numbers in order from smallest to largest:

17, 42, 45, 52, 54, 57, 58, 63

The mean is the sum of all the numbers divided by the total number of numbers.

If we remove the outlier (17), the data set becomes:

42, 45, 52, 54, 57, 58, 63

Mean:

Mean = (42 + 45 + 52 + 54 + 57 + 58 + 63) / 7 = 51

Median:

Median = (52 + 54) / 2 = 53

There is no mode in this set since no number appears more than once.

A satellite is to be put into an elliptical orbit around a moon as shown below. A vertical ellipse is shown surrounding a spherical object labeled, moon. The moon is a sphere with radius of 1000 km. Determine an equation for the ellipse if the distance of the satellite from the surface of the moon varies from 953 km to 466 km.

Answers

Answer:

The correct equation will be "[tex]\frac{x^2}{(1466)^2} +\frac{y^2}{(1953)^2} =1[/tex]".

Step-by-step explanation:

In the above question, the figure is missing. Please find below the attachment of the figure.

According to the question,

Radius of a moon,

r = 1000 km

The max. distance from moon's surface to the satellite,

a = 953 km

The min. distance from moon's surface to the satellite,

b = 466 km

Now,

As per the question or the diagram,

⇒ [tex]a_1=a+r[/tex]

        [tex]=953+1000[/tex]

        [tex]=1953 \ km[/tex]

⇒ [tex]b_1=b+r[/tex]

        [tex]=466+1000[/tex]

        [tex]=1466 \ km[/tex]

hence,

The equation of ellipse will be:

⇒ [tex]\frac{x^2}{b_1^2} +\frac{y^2}{a_1^2} =1[/tex]

On substituting all the values, we get

⇒ [tex]\frac{x^2}{(1466)^2} +\frac{y^2}{(1953)^2} =1[/tex]

How many combinations of 3 playing cards (from a 52-card deck) exist?

Answers

Answer:

22,100

Step-by-step explanation:

pls trust me i just took the test

The number of combination of 3 playing cards from 52 card deck is 22100.

What is Combination?

A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order.

Here, total cards = 52

         cards to be selected = 3

So, total possible combination = ⁵²C₃

                                                    = (52 X 51 X 50) / (3 X 2 X 1)

                                                   = 22100

Thus, the number of combination of 3 playing cards from 52 card deck is 22100.

Answers

Answer: 0.093 chance

Step-by-step explanation:

23 black + 32 blue + 8 white = 63 total

FIRST MARBLE IS BLUE:

32/63

SECOND MARBLE IS BLACK:

23/62

LAST MARBLE IS NOT BLUE:

30/61

MATH:

32/63*23/62*31/61 = 0.093

sorry if it’s wrong but I think it’s right

Answer:

.093

Step-by-step explanation:

There are 63 marbles in the jar

P(pick a blue) = 32/63

Since you are not replacing that marble, so there are 62 marbles in the jar, 31 blue, 23 black, 8 white

P(pick a black) = 23/62

Now there are 61 marbles in the jar. 22 black, 31 blue and 8 white

P(not a blue) = 30/61

P(blue, black, not blue) = (32/63)(23/62)(30/61)

                                      = .093
