A bag had 7 orange rocks , 6 green rock , 1 white rock ,7 black rocks , and 2 yellow you randomly pull a rock from the bag ,keep it out , and then pull out another one .

What is the probability of getting a yellow rock and then a n orange rock ?

Answers

Answer 1

Answer:

[tex]Probability = \frac{7}{253}[/tex]

Step-by-step explanation:

Given

[tex]Orange = 7[/tex]

[tex]Green = 6[/tex]

[tex]White = 1[/tex]

[tex]Black = 7[/tex]

[tex]Yellow = 2[/tex]

Required

Probability of selecting a yellow then orange rock

From the question, we understand that the probability is that of without replacement.

Since the yellow, is first picked.

We need to determine the probability of picking a yellow rock, first.

[tex]P(Yellow) = \frac{n(Yellow)}{Total}[/tex]

[tex]P(Yellow) = \frac{2}{7 + 6 + 1 + 7 + 2}[/tex]

[tex]P(Yellow) = \frac{2}{23}[/tex]

The rock has reduced by 1;

Next is to determine the probability of picking an orange rock

[tex]P(Orange) = \frac{n(Orange)}{Total - 1}[/tex]

[tex]P(Orange) = \frac{7}{7 + 6 + 1 + 7 + 2- 1}[/tex]

[tex]P(Orange) = \frac{7}{22}[/tex]

The required probability is calculated as thus:

[tex]Probability = P(Yellow) * P(Orange)[/tex]

[tex]Probability = \frac{2}{23} * \frac{7}{22}[/tex]

[tex]Probability = \frac{14}{506}[/tex]

[tex]Probability = \frac{7}{253}[/tex]

What are the first 4 terms use the explicit rule:
f(n)= 3n-1
(show your work)

Answers

Answer:

25811

Step-by-step explanation:

We are given the rule [ f(n) = 3n - 1 ] and n represents the term.

First term:

f(n) = 3n - 1

f(1) = 3(1) - 1

f(1) = 3 - 1

f(-1) = 2

Second term:

f(n) = 3n - 1

f(2) = 3(2) - 1

f(2) = 6 - 1

f(2) = 5

Third term:

f(n) = 3n - 1

f(3) = 3(3) - 1

f(3) = 9 - 1

f(3) = 8

Fourth term:

f(n) = 3n - 1

f(4) = 3(4) - 1

f(4) = 12 - 1

f(4) = 11

As you can see, the common difference is 3.

Best of Luck!

Answer:

2,5,8,11

Step-by-step explanation:

If n=1, 3n-1 =3*1-1 =3-1 =2

If n=2, 3n-1 =3*2-1 =6-1 =5

If n=3, 3n-1 =3*3-1 =9-1 =8

If n=4, 3n-1 =3*4-1 =12-1 =11

Answer:

x = 133                                         x = -7

Step-by-step explanation:

| x/7 - 9| = 10

There are two solutions, one positive and one negative

x/7 - 9 = 10             x/7 - 9 = -10

Add to to each side

x/7 - 9+9 = 10+9             x/7 - 9+9 = -10+9

x/7 = 19                              x/7 = -1

Multiply each side by 7

x/7 *7 = 19 *7                             x/7*7 = -1*7

x = 133                                         x = -7

Solve the equation: 3x − x − 5 = 2(x + 2) − 9 No solution, 1, All real numbers, 0

Answers

Answer:

I hope this helps

Step-by-step explanation:

Simplifying

3x + -1x + -5 = 2(x + 2) + -9

Reorder the terms:

-5 + 3x + -1x = 2(x + 2) + -9

Combine like terms: 3x + -1x = 2x

-5 + 2x = 2(x + 2) + -9

Reorder the terms:

-5 + 2x = 2(2 + x) + -9

-5 + 2x = (2 * 2 + x * 2) + -9

-5 + 2x = (4 + 2x) + -9

Reorder the terms:

-5 + 2x = 4 + -9 + 2x

Combine like terms: 4 + -9 = -5

-5 + 2x = -5 + 2x

Add '5' to each side of the equation.

-5 + 5 + 2x = -5 + 5 + 2x

Combine like terms: -5 + 5 = 0

0 + 2x = -5 + 5 + 2x

2x = -5 + 5 + 2x

Combine like terms: -5 + 5 = 0

2x = 0 + 2x

2x = 2x

Add '-2x' to each side of the equation.

2x + -2x = 2x + -2x

Combine like terms: 2x + -2x = 0

0 = 2x + -2x

Combine like terms: 2x + -2x = 0

0 = 0

0 = 0
