One pencil is randomly selected from a case containing 3 red, 4 green, 2 black, and 6 blue pencils. Find the probability for green and black.
Answer:
black= 2/15 green= 4/15
Step-by-step explanation:
so first we find out what this is out of so we add them all together which comes to 15. so there are 15 pencils. Since they're 4 green out of all 15 pencils it will be a 4/15 its same for black with 2/15. (sorry if it's not good, I hope this helped)

Jessica is selling books during the summer to earn money for college. She
earns a commission on each sale but has to pay for her own expenses.
After a month of driving from neighborhood to neighborhood and walking
door-to-door, she figures out that her weekly earnings are approximately a
a linear function of the number of doors she knocks on.
She writes the equation of the function like this: E(X) = 7x - 25, where x is the
number of doors she knocks on during the week and E(x) is her earnings for
the week in dollars.
Which of the following are reasonable interpretations of the y-intercept of
Jessica's function?
Check all that apply.
A. Her expenses are $25 per week.
B. If she does not knock on any doors at all during the week, she will lose $25.
C. She will lose $7 per week if she does not knock on any doors.
D. She can earn $7 per week even if she does not knock on any doors.
Answer:
B.

Is the mean greater than, less than, or equal to the median?
Answer:
One of the basic tenets of statistics that every student learns in about the second week of intro stats is that in a skewed distribution, the mean is closer to the tail in a skewed distribution. So in a right skewed distribution (the tail points right on the number line), the mean is higher than the median.

Which equation best matches the graph shown below?
The quadratic function that best matches the graph is given as follows:
y = -0.2(x + 3)² + 5.
How to define the quadratic function given it's vertex?The quadratic function of vertex(h,k) is given by the rule presented as follows:
y = a(x - h)² + k
In which:
h is the x-coordinate of the vertex.k is the y-coordinate of the vertex.a is the leading coefficient.The coordinates of the vertex for this problem are given as follows:
(-3, 5).
Hence:
y = a(x + 3)² + 5
When x = 0, y = 3, hence the leading coefficient a is obtained as follows:
3 = 9a + 5
9a = -2
a = -0.2. (rounded).
Hence the function is:
y = -0.2(x + 3)² + 5.

QUESTION 30 Given the following probability distributions, what are the expected returns for the market and for Security J? State Pr i ᵣM ᵣJ
1 0.3 -10% 40% 2 0.4 10 -20 3 0.3 30 30
Expected return for the marketE(RM) = ∑ Pr(RM) = 0.3(-10%) + 0.4(10%) + 0.3(30%)= -3% + 4% + 9%= 10%Therefore, the expected return for the market is 10%Expected return for Security JE(RJ) = ∑ Pr(RJ) = 0.3(40%) + 0.4(-20%) + 0.3(30%)= 12% - 8% + 9%= 13%Therefore, the expected return for Security J is 13%..
The above calculation represents the probability distributions of returns for the market and Security J. From the above calculation, it can be observed that the expected return for the market is 10%.
The expected return is a prediction that helps investors to get an idea about the possible returns of an investment.
The expected return is calculated by multiplying each possible outcome by its corresponding probability and then adding all the products.
By calculating the expected return for the market, investors can predict the market performance and make investment decisions accordingly. Similarly, the expected return for Security J is 13%, which implies that Security J has a higher expected return than the market.
By analyzing the expected return, investors can decide which investment would be more profitable for them.
In conclusion, the expected return for the market and Security J can be calculated using probability distribution. The calculation of the expected return is beneficial for investors to understand the market performance and make investment decisions accordingly.

4x = 0

The correct option is A.
What is an equation?A pair of algebraic equations with the equal symbol (=) in the center and the same value is referred to as an equation.
The steps she used to solve the equation are valid, and she correctly determined that x = 0.
As per the information provided,

6x + 3 = 2x + 2 + 1
6x + 3 = 2x + 3

Answer: the fraction form is 331/500
Step-by-step explanation:
You and a friend go to a local Mexican restaurant for lunch. You order 2 soft tacos and 3 burritos for a total bill of
$8.85. Your friend orders 4 soft tacos and 2 burritos for a total bill of $12.70. How much does one taco cost? How
much does on burrito cost?
Answer:
A soft taco costs $1.25 and a burrito costs $2.50
Step-by-step explanation:
To start to find the cost of each, you need to set up a system of equations. Start by using x for the cost of a soft taco. Then use y for the cost of a burrito. First you can compile an equation for what you paid.
3x + 3y = 11.25
Now you can do the same with your friend's purchase.
4x + 2y = 10.00
Now to solve we can use a number of different methods. We'll use elimination this time. To use that, multiply the first equation by -2 and the second equation by 3. Then line them up like this:
-6x - 6y = -22.50
12x + 6y = 30.00
Now we add them straight through to cancel the y's and solve for x.
6x = 7.50
x = 1.25
Now we know the cost of a soft taco is $1.25 and we can find the burrito cost by using the taco cost in either equation.
3x + 3y = 11.25
3(1.25) + 3y = 11.25
3.75 + 3y = 11.25
3y = 7.50
y = 2.50
So we know that a burrito costs $2.50

Answer:
(x, y) ⇒ (x, y+6)
Step-by-step explanation:
Reflection of a value a across a point p to make b requires that a, b, and p satisfy the relation ...
p = (a+b)/2
2p = a + b
b = 2p - a
This is true for any sort of reflection. Here we have a reflection across the horizontal line y=-1, followed by a reflection across the horizontal line y=2. These reflections do not change the x-coordinate of a point, but they change the y-coordinate in accordance with the above relation.
Reflection across y = -1:
(x, y) ⇒ (x, 2(-1)-y) = (x, -2-y)
Reflection of that across y = 2:
(x, -2-y) ⇒ (x, 2(2) -(-2-y)) = (x, y+6)
The composition of the two reflections results in a translation upward of 6 units: (x, y) ⇒ (x, y+6)

Step-by-step explanation:
To evaluate f(8), substitute x = 8 into f(x) , that is
f(8) = [tex]\sqrt{2(8)+9}[/tex] = [tex]\sqrt{16+9}[/tex] = [tex]\sqrt{25}[/tex] = ± 5
-----------------------------------------------------
Equating
[tex]\sqrt{2x+9}[/tex] = 3 ( square both sides )
2x + 9 = 9 ( subtract 9 from both sides )
2x = 0 ⇒ x = 0
Thus
f(0) = 3
