How do you find the probability of two events A and B when A and B are independent? dependent?

A.For independent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then multiply. For dependent events, find the probability of the first event, find the probability of the second event, and then multiply.

B.For independent events, find the probability of the first event, find the probability of the second event, and then multiply. For dependent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then multiply.

C.For independent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then add. For dependent events, find the probability of the first event, find the probability of the second event, and then add.

D.For independent events, find the probability of the first event, find the probability of the second event, and then add. For dependent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then add.

Answers

Answer 1

Answer:

I think it is A, but i am not sure, sorry

Step-by-step explanation:

Two events are independent if the result of the second event is not affected by the result of the first event. If A and B are independent events, the probability of both events occurring is the product of the probabilities of the individual events.

A. For independent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then multiply. For dependent events, find the probability of the first event, find the probability of the second event, and then multiply.

The relationship is proportional.

In the table, we see a rate of change of 5 when multiplying by the bag of screws to get the price:

2 • 5 = 10
4 • 5 = 20
7 • 5 = 35

Because all of the equations are true, we know the relationship between the number of bags of screws and the price is proportional.

Answer: proportional

Step-by-step explanation:

if you divide 10 by 2 you get 5.

since 4 times 5 is 20 and 7 times 5 is 35

the table is proportional since there is a set rate of change

Surface area is the sum of the areas of all the sides.

The bottom side(the rectangle with dimensions 11.9 and 17.4): 11.9 * 17.4 = 207.06 * 1 = 207.06(because there is only one of this shape)

The rectangular sides(dimensions 10.5 and 14): 10.5 * 14 = 147 * 2 = 294 for both sides

The triangular sides(17.4 and 7): (17.4 * 7) / 2(because it a triangle) = 60.9 * 2 = 121.8(because there are two sides)

What is the maximum number of 2cm cubes that can fit into a box measuring 10cm by 8cm by 5cm?

Answers

Answer: The volume of box is 6×8×10 cm^3

All of 6,8 and 10 are divisible by 2 so your cubes will fill the box, the volume of the cube is 2×2×2=8 cm^3 divide the volume of the box by 8; number of cubes fitting in the box is 6×10=60

Step-by-step explanation:All of 6,8 and 10 are divisible by 2 so your cubes will fill the box, the volume of the cube is 2×2×2=8 cm^3 divide the volume of the box by 8; number of cubes fitting in the box is 6×10=60

Answer:

50 cubes

Step-by-step explanation:

The maximum number of 2cm cubes that can fit into a box measuring 10cm by 8cm by 5cm is 50 cubes.

You can find this by dividing the total volume of the box (10 x 8 x 5 = 400 cm^3) by the volume of a single cube (2 x 2 x 2 = 8 cm^3). So 400cm^3 / 8cm^3 = 50 cubes.

Hence, The maximum number of 2cm cubes that can fit into a box measuring 10cm by 8cm by 5cm is 50 cubes.

How many cubes are there for each of the​ length, width, and height of the​ prism?
The length has
nothing ​cubes, the width has
nothing ​cubes, and the height has
nothing cubes.

Answers

Answer:

The length has 3 cubes

The width has 7 cubes

The height has 5 cubes

Step-by-step explanation:

Given

[tex]Length = 1\frac{1}{2}yd[/tex]

[tex]Width = 3\frac{1}{2}yd[/tex]

[tex]Height = 2\frac{1}{2}yd[/tex]

[tex]l = \frac{1}{2}yd[/tex] --- edge length

Required

Determine the number of cubes in each dimension

To do this, we divide the dimension by the edge length

For the length, we have:

[tex]n_{Length} = \frac{Length}{l}[/tex]

[tex]n_{Length} = \frac{1\frac{1}{2}}{\frac{1}{2}}[/tex]

Express as:

[tex]n_{Length} = 1\frac{1}{2} \div \frac{1}{2}[/tex]

Change to product

[tex]n_{Length} = 1\frac{1}{2} * \frac{2}{1}[/tex]

[tex]n_{Length} = 1\frac{1}{2} * 2[/tex]

[tex]n_{Length} = 3[/tex]

3 cubes in the length

For the width, we have:

[tex]n_{Width} = \frac{Width}{l}[/tex]

[tex]n_{Width} = \frac{3\frac{1}{2}}{\frac{1}{2}}[/tex]

Express as:

[tex]n_{Width} = 3\frac{1}{2} \div \frac{1}{2}[/tex]

Change to product

[tex]n_{Width} = 3\frac{1}{2} * \frac{2}{1}[/tex]

[tex]n_{Width} = 3\frac{1}{2} * 2[/tex]

[tex]n_{Width} = 7[/tex]

7 cubes in the width

For the height, we have:

[tex]n_{Height} = \frac{Height}{l}[/tex]

[tex]n_{Height} = \frac{2\frac{1}{2}}{\frac{1}{2}}[/tex]

Express as:

[tex]n_{Height} = 2\frac{1}{2} \div \frac{1}{2}[/tex]

Change to product

[tex]n_{Height} = 2\frac{1}{2} * \frac{2}{1}[/tex]

[tex]n_{Height} = 2\frac{1}{2} * 2[/tex]

[tex]n_{Height} = 5[/tex]

Answer:

Step-by-step explanation:

7 ⋅ 18 = 126

126 ÷ 2 = 63

a^2 + b^2 = c^2

b = √9^2 - 7^2

b = √81 - 49

b = √32

b = 5.7 (Rounded to nearest tenth)

7 ⋅ 5.7 = 39.9

39.9 ÷ 2 = 19.95

63 + 19.95 = 82.95

Answers

Answer:

Bottles (b) = 5

Step-by-step explanation:

1. 1 1/8B + 15/16 = 6 9/16

2. 1 1/8B = 105/16 - 15/16

3. 1 1/8B = 90/16

4. (9/8) (8/9B) = 90/16 (9/8)

5. B = 10/2 = 5

The number of bottles b should be 5.

Given that,

Mora preparing her pack for a hike. Her empty pack weighs 15 by 16 pound. She adds some water bottle that each weigh 1 1 by 8 pound. Now Mora's pack weighs 6 9by 16 pounds.

Based on the above information, the calculation is as follows:

[tex]1 \frac{1}{8}B + 15\div 16 = 6 \frac{9}{16}\\\\ 1 \frac{1}{8}B = \frac{105}{16} - \frac{15}{16}\\\\1 \frac{1}{8}B = 90\div 16\\\\(9\div 8) (8\div 9B) \\\\= 90\div 16 (9\div 8)\\\\B = 10\div 2[/tex]

Step-by-step explanation:

hoped this helped :)

First off, the formula for volume is :
length x width x height
Or
base x height

Assuming the each unit is 1, there is 2 rows of 3, or 6 units as the base.

There are 5 units up, representing height.

So, you multiply 6 x 5, and get 30.

Therefore, your answer should be C!
