5. A ja contains 11 green marbles, 7 red marbles, and 6 blue marbles. A marble is selected at random, not replaced, and then a second marble is selected. What is the probability ofselecting a blue marble followed by a green marble?
Answer: 11/92
Explanation:
Probability is expressed as
number of favorable outcomes/number of total outcomes
From the information given,
number of green marbles = 11
number of red marbles = 7
number of blue marbles = 6
Total number of marbles = 11 + 7 + 6 = 24
Probability of selecting a blue marble = 6/24 = 1/4
Since the marble is not replaced, total number of marbles left = 24 - 1 = 23
Probability of selecting a green marble = 11/23
The probability of selecting a blue marble followed by a green marble is
1/4 x 11/23
= 11/92
1. Do you recommend this person open a credit card account? Why or why not?
2. If they do open the new credit card account, what's one thing this individual should monitor or use caution?
Crystal-
Took time off after high school and during the first year, worked full-time and moved out of her parents house
Is responsible for her own expenses
Took out a large car loan which she quickly fell behind on in payments
Overdrew her checking account numerous times, spending money she didn't have to live a fun, carefree lifestyle
In year two, traded in the car for a much cheaper one, settled her outstanding debt on the car loan, and put herself on a much stricter budget
Now moved back in with her parents and enrolled in community college
Considering applying for her first credit card
1. Crystal can open a new credit card account.
2. If Crystal opens a credit card account, she should keep track of her spending and pay monthly bills on time.
Since Crystal has paid off her debts from the car loan, moved to her parent's home, and enrolled in community college, the chances of her getting into debt are quite low, so she can get a credit card to take care of her expenses as long as she works full time and keeps track of her monthly bills.
If Crystal opens a credit card account, she should keep a spending track and pay her monthly bills on time. She should work full-time and make sure that she pays it off.

The side lengths of the right triangle in exact form are z = (15√3)/2, x = 15/2, y = (15√3)/4, a = 15/4 and b = 45/4.
How determine the sides of a right triangle using trigonometric ratios?Three out of the six functions used in trigonometry is expressed as;
sin = opposite / hypotenuse
cos = adjacent / hypotenuse
tan = opposite / adjacent
From diagram, we solve for side z of the right triangle.
cosθ = adjacent / hypotenuse
cos( 30° ) = z / 15
Solve for z
z = cos( 30° ) × 15
z = (√3)/2 × 15
z = (15√3)/2
Next solve for side x
sinθ = opposite / hypotenuse
sin( 30° ) = x / 15
x = sin( 30° ) × 15
x = 15/2
Solve for side y
sinθ = opposite / hypotenuse
sin( 60° ) = y / 15/2
y = sin( 60° ) × 15/2
y = (15√3)/4
Solve for side a
cosθ = adjacent / hypotenuse
cos( 60° ) = a / 15/2
a = cos( 60° ) × 15/2
a = 15/4
Solve for side b
b = 15 - a
b = 15 - 15/4
b = 45/4
Therefore the length of side of b is 45/4

Tell whether the data represents a linear, an exponential, or a quadratic function. Then, write the function. Picture is attached. I need help!
SOLUTION:
Case: Equations
Method:
The table:
Plotting the points
Studying the points, could either be quadratic or exponential.
We will proceed to test the points but because the increase of the y values as x increases from left to right is not a fine pattern, it will most likely not be exponential.
Next, we test a quadratic model on the graph
[tex]y=ax^2+bx+c[/tex]Final answer:
Quadratic function
[tex]y=x^2+4x-12[/tex]To be linear, you'd need a fixed increase in the y-values for a constant increase in the x-values. As x increases by 1 in each new point, your y-values increase by 1, 3, 5, and 7 respectively. That is not the same increase each time. This is not linear.
To be exponential, you need a fixed percent increase in the y-values between the points. From (-2,-16) to (-1,-15), your increase is 1/16 or 6.25%. From (-1,-15) to (0,-12), your increase is 3/15 or 20%. That is not a constant percent increase.
The only option left is quadratic.
To find the function, start with c = -12, based on the point (0,-12).
This gives you f(x) = ax^2 + bx -12
Next plug in (2,0) into f(x): 0 = 4a + 2b - 12
And plug in (1,-7) into f(x): -7 = a + b -12
You now have two equations with two unknowns.
Solve equation 2 for a:
5-b = a
Substitute that into equation 1
0 = 4(5-b) + 2b - 12
0 = 20 -4b + 2b - 12
-8 = -2b
4 = b
Substitute that b-value into 5-b=a
5 - 4 = a
1 = a
You have your three values and have your function:
f(x) = 1x^2 + 4x - 12 or f(x) = x^2 + 4x - 12
You can confirm that the other points also fit with this function.

Given that,
The total tip for a four-person meal at a restaurant is $122, people $8018. What proportion of a tip is that? Four restaurant beers cost 120 each, and the group tip is $180.
We have to calculate the how much percentage of a tip is there.
In a variety of situations, such as restaurants, hotels, salons, and other establishments in the service sector, leaving a tip is common. Knowing how to compute a tip and knowing how much to tip is crucial for a variety of reasons, including the fact that many service sector personnel, like waiters, rely heavily on gratuities for the majority of their income. This means that these experts might not be able to support themselves and their families without tips.

We have a initial population P(0) of 3800.
We know that the population is decreasing by 1.4% each year, so the population at year 1 (2009) we will have a population of:
[tex]\begin{gathered} P(1)=P(0)-0.014\cdot P(0) \\ P(1)=(1-0.014)\cdot P(0) \\ P(1)=0.986\cdot P(0) \end{gathered}[/tex]We can generalize this for P(n), where n is the number of years from 2008.
[tex]\begin{gathered} P(2)=0.986\cdot P(1)=0.986\cdot(0.986\cdot P(0))=0.986^2\cdot P(0) \\ \Rightarrow \\ P(n)=0.986^n\cdot P(0)=0.986^n\cdot3800=3800\cdot0.986^n \end{gathered}[/tex]From 2008 to 2013 we have 2013-2008=5 years, so for the year 2013, the value of n is n=5.
Then, the population for 2013 will be P(5) and can be calculated as:
[tex]P(5)=3800\cdot0.986^5\approx3800\cdot0.932\approx3541[/tex]Answer: the predicted population for the year 2013 is 3541.

Essential Question How can you write an algebraic expression?
Answer:
Step-by-step explanation:
In algebraic expressions that use variables (written as letters), you can write them directly after a normal number, with no symbol between them.
...
Use a ⋅ or × sign if you see words like double, per, or product.
Twice 16 → 2 ⋅ 16.
Five per day → 5 ⋅ d or 5d. ...
The product of 8 and 20 → 8 ⋅ 20.
Given the right triangle shown, solve for X, Y and Z. The triangle may not be drawn to scaleA. x=1.86feet, y=4.41 feet and z=65 degreeB.x=4.41 feet, y=1.69 feet, and z=155 degreeC. x=8.58 feet, y=9.46 feet and z=65 degreeD.x=9.46 feet, y=8.58 feet and z=155 degree
Since the triangle is a right-angled triangle, we can use SohCahToa to find x
Using the ratio
[tex]Tan25=\frac{\text{opposite}}{\text{adjacent}}[/tex]Opposite = 4ft
adjacent = x
Substituting these values yield
[tex]\begin{gathered} \text{Tan 25 =}\frac{4}{x} \\ x\text{ =}\frac{4}{\tan 25} \\ x\text{ =8.57}8ft \\ x\approx8.58ft \end{gathered}[/tex]To find Z we use the fact that the sum of angles in a triangle is 180 degrees
so that in triangle XYZ
90 + 25 +Z = 180
Z = 180 - 115
Z= 65 degrees
We will now use Pythagoras theorem to find y
[tex]\begin{gathered} \text{For that} \\ y^2=x^2+4^2 \\ \text{but x = 8.58ft} \\ y^2=8.58^2+4^2 \\ y=\sqrt[]{73.6164\text{ +16}} \\ y\text{ =9.46 ft} \end{gathered}[/tex]
Hence x= 8.58 ft, y= 9.46ft and Z = 65 degrees, Option C
