An urn contain 2 white marbles, 3 green marbles, and 5 red marbles. A marble is drawn and then replaced. Then a second marble is drawn. What is probability that the first marble was white and the second was green?

Answers

Answer 1

Answer:

1/5

Step-by-step explanation:

To find this you would need to multiply the probability of pulling a white marble to the probability of pulling out a green marble.

1)First you would need the probability of pulling out a white marble. There are 10 marbles in total and out of those 2 are white. So the probability of pulling out a white marble would be 2/10. If you simplify that you would get 1/5 for the probability of pulling out a white marble.

2)Next, you would find the probability of pulling out a green marble. Using the same process that we used to find the probability of pulling out a white marble, we would find the answer to be 3/10. All that we did here was green marbles/total marbles. By filling that in we got 3/10 for the probability of pulling out a green marble.

3)Now all that is left is doing probability of pulling a white marble × probability of pulling out a green marble. This would be 1/5 × 3/10. After solving the answer would be 3/15 which we would simplify down to 1/5 as our final answer.

Answers

Answer:

I believe your answer would be

Step-by-step explanation:

Using that formula, we can substitute in the values we need that are given to us in the question:

h = 12

r = 4

Now we need to use the formula.

V = 1/3 (pi) (4²) (12)

First lets do the exponent.

4² = 16

V = 1/3 (pi) (16) (12)

Now lets do pi × 16.

pi × 16 = 50.2654824574.

Now we have:

V = 1/3 (50.2654824574) (12)

Multiply 50.2654824574 and 12.

50.2654824574 × 12 = 603.185789489

Now all we have:

V = 1/3 (603.185789489)

Multiply them.

V = 201.06192983

So, your answer is V ≈ 201.06192983, or 201.

Answers

if ben makes $35.00 per hour and then gets a ten percent raise what is his new salary. Show your work

Answers

Answer:

$38.50 per hour

Step-by-step explanation:

10% = 0.1

0.1 × 35.00 = 3.50

35.00 + 3.50 = 38.50

Answer:

The answer is $38.50

Step-by-step explanation:

35 x 0.1 = 3.5 (0)

35 + 3.50 = 38.50

The reason we do 0.1 is because 10% written in decimal form is 0.1 and since 35.00 is a decimal we made the percent into a decimal to make it even.

How to find the mean value of a data set?

The mean value of the data set is the ratio of the sum of the data set's values to number of values it has.

If the data set consists of values

x_1, x_2, ..., x_n

, then we get the mean value as:

[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]

The number of storybooks owned by eight classmates is shown below:

8, 9, 9, 7, 8, 6, 9, 8

Part A:

[tex]\overline{x} = \dfrac{ 8+ 9+ 9+ 7+ 8+ 6+ 9+ 8}{8}[/tex]

Therefore, The mean is 8

Part B: Absolute Deviation= 0  

subtract each number by the mean

8-8+9-8+9-8+7-8+8-8+6-8+9-8+8-8=0

(then divide sum by mean) 0 divided by 8 = 8

Answers

Answer:

Step-by-step explanation:

-8/2= -4

Answer:

-1/4 or -0.25

Step-by-step explanation:

n=2 and p=-8

substitute p as the numerator and n as the denominator in the fraction

2/-8 simplifies to 1/-4, the sign moves to the front of the fraction because any positive number divided by a negative number will be negative and it is common practice, so the answer is -1/4.

-1/4 is equal to -0.25 in decimal. -0.25 is 1/4 of -1.
