A bag contains three blue marbles, five red marbles, and four green marbles.

Part A: What is the probability of selecting a red marble?

Part B: What is the probability of selecting three red marbles without replacement?

Part C: In a short paragraph, explain in your own words your work to Step B

Answers

Answer 1

Answer:

Below.

Step-by-step explanation:

The total number of marbles is 12.

Part A.

Prob(Red marble) = 5/12.

Part B.

Prob(pick 3 red marbles without replacement) = 5/12 * 4/11 * 3/10 = 1/22.

Part C.

The probability of the first being red is 5/12 because there are 5 red out of a total of 12 marbles. After that there are only 4 marbles and the total is 11 ( 1 marble less). Finally on the 3rd pick there are 3 red and a total of 10. WE then multiply these 3 probabilities.

since the domain of the function is given, you just have to plug in the numbers to the function:

13x - x²

it's basically asking: if x was any of the numbers in the given domain, what would it be the answer be?

for example:

I'll solve for -2 and you can do the rest.

13 • -2 -(-2 ²) =

13 • 2 + 4 =

26 + 4 = 30

Step-by-step explanation:

Answer:

No real Solutions

Step-by-step explanation:

Step one: The coefficient on -6x is -6. So b= -6

Step two: Add (b/2)^2 to each side. in our case it is 9

x^2-6x+9= -49

Step three: Factor left side

(x-3)^2 = -49

Step four: take the square root

x-3 = ±√-49

Step five: add 3 to both sides

x = 3 ± √-49

So there is no real solutions

∠A and \angle B∠B are supplementary angles. If m\angle A=(4x-30)^{\circ}∠A=(4x−30)

and m\angle B=(4x-14)^{\circ}∠B=(4x−14)

, then find the measure of \angle A∠A.

Answers

Answer:

the measure of ∠A. is 87∘

Step-by-step explanation:

Two angles are said to be supplementary angles if the sum of those angles is 180 degrees.

_________________________________________________

Given

∠A=(4x−30) ∘

∠B=(4x−14) ∘

Fir angles to be supplementary

∠A + ∠B = 180

(4x−30) ∘ + (4x−14) ∘ = 180∘

(8x -54 )∘ = 180∘

=> 8x =  180∘ +  54∘= 234∘

=> x = 234∘/8 = 29.25∘

Thus,

∠A=(4x−30) ∘

∠A=(4*29.25−30) ∘ =( 117 - 30 ) ∘ = 87∘

Thus,

the measure of ∠A. is 87∘

Write three factors of 24 which have a sum of more than 37 and less than 40

Answers

Answer:

24, 12, 2

Step-by-step explanation:

24, 12, and 2 are all factors of 24.

24+12+2=38

37<38<40

the three factors of 24 that have a sum between 37 and 40 are 2, 12, and 24, with a sum of 38. Another combination is 4, 8, and 24, also with a sum of 38.

To find three factors of 24 with a sum between 37 and 40, we can start by listing the factors of 24:

1, 2, 3, 4, 6, 8, 12, 24

Next, we'll try different combinations of these factors to see if any three of them add up to a sum between 37 and 40:

1 + 2 + 24 = 27 (not within the desired range)

1 + 3 + 24 = 28 (not within the desired range)

1 + 4 + 24 = 29 (not within the desired range)

1 + 6 + 24 = 31 (not within the desired range)

1 + 8 + 24 = 33 (not within the desired range)

1 + 12 + 24 = 37 (not within the desired range)

2 + 3 + 24 = 29 (not within the desired range)

2 + 4 + 24 = 30 (not within the desired range)

2 + 6 + 24 = 32 (not within the desired range)

2 + 8 + 24 = 34 (not within the desired range)

2 + 12 + 24 = 38 (within the desired range)

3 + 4 + 24 = 31 (not within the desired range)

3 + 6 + 24 = 33 (not within the desired range)

3 + 8 + 24 = 35 (not within the desired range)

3 + 12 + 24 = 39 (within the desired range)

4 + 6 + 24 = 34 (not within the desired range)

4 + 8 + 24 = 36 (within the desired range)

4 + 12 + 24 = 40 (not within the desired range)

6 + 8 + 24 = 38 (within the desired range)

6 + 12 + 24 = 42 (not within the desired range)

8 + 12 + 24 = 44 (not within the desired range)

Therefore, the three factors of 24 that have a sum between 37 and 40 are 2, 12, and 24, with a sum of 38. Another combination is 4, 8, and 24, also with a sum of 38.

Select all the values (d,n) that could be solutions to the equation.

Answers

One solution is x = 1 and y = 443 because
0.10(1) + 0.05(443) = 22.25.
So, (1, 443) is a solution.
Since, 1 dime = 2 nickels,
Increment of 1 in x-value = Decrease of 2 in y-value.
Therefore, the set of possible solutions are {(1, 443), (2, 441), (3, 439), (4, 437),......(222, 1)}
