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]

If 3 tickets to a certain show cost $13.20, what would 7 tickets cost?
What is this answer?
Answer:
$ 30.8Step-by-step explanation:
ratio and proportion:
3 tickets = 7 tickets
$13.20 x
then cross multiply: 3 (x) = 13.20 (7)
simplify: 3x = 92.4
solve for x = 92.4 / 3
x = $ 30.8
therefore,
7 tickets costs $ 30.8
Solve the equation: 3x − x − 5 = 2(x + 2) − 9 No solution, 1, All real numbers, 0
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
Solving
0 = 0
Couldn't find a variable to solve for.
This equation is an identity, all real numbers are solutions.
10s - 5 = 20
Value of s
Answer:
2.5
Step-by-step explanation:
10s-5=20
(add 5 to both sides)
10s=25
(divide both sides by 10)
s=2.5
Answer:
s = 2.5
Step-by-step explanation:
you need to figure out what multiplied by 10 will give you 25, because then you have to subtract 5 in the second part of the equation to get 20.
10 multiplied by 2.5 equals 25, so s = 2.5

Step-by-step explanation:
Line g has an equation of y = -9x - 9. Perpendicular to line g is line h, which passes
through the point (9,-5). What is the equation of line h?
Write the equation in slope-intercept form. Write the numbers in the equation as proper fractions, improper fractions, or integers.
Answer:
y=1/9x - 6
Step-by-step explanation:
perpendicular lines have slops that are the negative reciprocal of one another. After you find the slope you then plug in the point to find b using the equation: -5=1/9(9) + b .

Problem-solving Ava and Ben set the alarms on their phones to sound at 6:30 am
Both alarms sound together at 6:30 am.
Ava's alarm then sounds every 24 minutes.
Ben's alarm then sounds every 30 minutes.
Use the lowest common multiple to find out when both alarms next sound
together.
Answer:
08:30 am
Step-by-step explanation:
30 * 1 =30 24 * 1 = 24
30* 2 = 60 24 * 2 = 48
30 * 3 = 90 24 * 3 = 72
30 * 4 = 120 24 * 4 = 96
24 * 5 = 120
The lowest common multiple ist 120.

Which equation represents a line parallel to the line shown on the graph?
y=4x-1
y=-4x+3/5
y=1/4x+5
y=-1/4x-1
Answer:
It is -1/4-1. The slope of the line is -1/4, so the only line that can be parallel is a line with the same slope.

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

What are the first 4 terms use the explicit rule:
f(n)= 3n-1
(show your work)
Answer:
25811Step-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:
