Among the given statements, c. The theoretical probability of selecting a blue or green marble from the bag is 2/3. which is not true.
What is the probability of an event?The probability of an event is the fractional value determining how likely is that event to take place. If the event is denoted by A, the number of outcomes favoring the event A is n and the total number of outcomes is S, then the probability of the event A is given as:
P(A) = n/S.
What are the odds of a given event?When a given event suppose A, has a Probability of occurring = P(A) and Probability of not happening = 1 - P(A).
When we calculate the odds in favor of event A, the value is given by the ratio, P(A):(1 - P(A)).
When we calculate the odds against the event A, the value is given by the ratio, (1 - P(A)):P(A).
How do we solve the given question?We are informed that a bag contains eleven red marbles, seven blue marbles, nine green marbles, and thirteen yellow marbles.
Let the event of selecting a red marble from the bag be R.
Number of outcomes favoring R = 11 (number of red marbles)
Total number of outcomes = 40 (number of marbles in the bag)
∴ The probability of the event R is P(R) = 11/40
1 - P(R) = 1 - 11/40 = 29/40
Let the event of selecting a blue marble from the bag be B.
Number of outcomes favoring B = 7 (number of blue marbles)
Total number of outcomes = 40 (number of marbles in the bag)
∴ The probability of the event B is P(B) = 7/40
1 - P(B) = 1 - 7/40 = 33/40
Let the event of selecting a green marble from the bag be G.
Number of outcomes favoring G = 9 (number of green marbles)
Total number of outcomes = 40 (number of marbles in the bag)
∴ The probability of the event G is P(G) = 9/40
1 - P(G) = 1 - 9/40 = 31/40
Let the event of selecting a yellow marble from the bag be Y.
Number of outcomes favoring Y = 13 (number of yellow marbles)
Total number of outcomes = 40 (number of marbles in the bag)
∴ The probability of the event Y is P(Y) = 13/40
1 - P(y) = 1 - 13/40 = 27/40
Now, we analyze all the options, to check for the ones which are not true.
a. The theoretical probability of selecting a red marble from the bag is 27.5%.
The probability of selecting a red marble P(R) = 11/40 =11/40 * 100% = 27.5%, which is the same we are looking for.
∴ The statement is true.
b. The odds of selecting a yellow marble from the bag are 13 to 27.
The odds of selecting a yellow marble (odds in favor) = P(Y)/(1 - P(Y)) = 13/27 or 13 to 27, which is the value we are looking for.
∴ The statement is true.
c. The theoretical probability of selecting a blue or green marble from the bag is 2/3.
The probability of selecting a blue or green marble from the bag = P(B) + P(G) = 7/40 + 9/40 = 16/40 = 2/5, which is not the value we are looking for.
∴ The statement is not true.
d. The odds of selecting a red or blue marble are 9/11.
The probability of selecting a red or blue marble from the bag
P(R+B) = P(R) + P(B) = 11/40 + 7/40 = 18/40 = 9/20.
1 - P(R+B) = 1 - 9/20 = 11/20
∴ Odds of selecting a red or blue marble (odds in favor)
= P(R+B)/(1 - P(R+B)) = (9/20)/(11/20) = 9/11, which is the value we are looking for.
∴ The statement is true.
So, among the given statements, c. The theoretical probability of selecting a blue or green marble from the bag is 2/3. which is not true.

What is the vertical shift of the graph of the parent cosecant function to the graph of the function below?
A. 1 unit down
B. 2 units down
C. 3 units down
D. 4 units down
Answer:
Option: C is the correct answer.
C. 3 units down.
Step-by-step explanation:
We know that the graph of a cosecant function has a minimum value for a upward open curve as : 1
It could be seen from the graph.
But here the minimum value of the upward open curve in the transformed function is: -2
This means that the vertical shift is given by:
-2-1=-3
This means that there is a vertical shift of 3 units down in the parent function.

Answer:
11.25
Step-by-step explanation:
The slope is [tex]\frac{3}{4}[/tex]
Using this we can find Δx and Δy.
The slope is Δy/Δx
And Δx is 15 since the number of units from 12 to 27 is 15.
So Δy/15 = [tex]\frac{3}{4}[/tex]
Multiply so they have common denominators.
4Δy/60 = [tex]\frac{45}{60}[/tex]
Multiply each side by 60 and solve.
4Δy = 45
Δy = 11.25
So the length of x is 11.25
if the box holds 24 of these sugar cubes,what is the total volume of the box?
Answer:
[tex]V_{box}=3u^{3}[/tex]
Step-by-step explanation:
The complete question is
If the box holds 24 of these sugar cubes what is the total volume of the box.
The sugar cubes are 1/2 x 1/2 x 1/2
The total volume of the box would be the volume of each sugar cube multiplied by 24, because the box is formed by those 24 sugar cube.
The volume of one sugar cube
[tex]V_{cube}=\frac{1}{2}\times \frac{1}{2} \times \frac{1}{2}=\frac{1}{8} u^{3}[/tex]
We have 24 of them, so the volume of the whole box is
[tex]V_{box}=24\frac{1}{8}u^{3}\\ V_{box}=3u^{3}[/tex]
Therefore, the volume of the box is
[tex]V_{box}=3u^{3}[/tex]
To find the total volume of the box holding 24 sugar cubes, calculate the volume of a single sugar cube and multiply by 24.
Explanation:The total volume of the box can be determined by finding the volume of a single sugar cube and multiplying it by the number of cubes in the box. Since the question does not provide specific dimensions of the sugar cube, let's assume the cube has sides of 1 cm. The volume of a cube is found by cubing the length of a side. So, the volume of a single sugar cube is 1 cm x 1 cm x 1 cm = 1 cubic cm. Since the box holds 24 sugar cubes, the total volume of the box is 24 cubic cm.

Suppose that there are two types of tickets to a show: advance and same-day. Advance tickets cost $35 and same-day tickets cost $15. For one performance, there were 60
tickets sold in all, and the total amount paid for them was $1300. How many tickets of each type were sold?
Answer:
26 of each
Step-by-step explanation:
To solve write this as an equation (35x)+(15x)=1300
For this case we have:
x: Variable representing the types of advance input
y: Variable representing the same-day entry types
We have according to the cost:
[tex]35x + 15y=1300[/tex]
According to the number of tickets:
[tex]x + y = 60[/tex]
We have a system of two equations with two unknowns:
[tex]35x + 15y = 1300\\x + y = 60[/tex]
We multiply the second equation by -35:
[tex]35x + 15y = 1300\\-35x-35y = -2100[/tex]
We add:
[tex]-20y = -800\\y = \frac {800} {20}\\y = 40.[/tex]
Thus, 40 same-day tickets were sold.
[tex]x + 40 = 60\\x = 60-40\\x = 20[/tex]
20 advance tickets were sold
Answer:
20 advance
40 same-day

Which measure of center would be best to compare the data sets?
Answer:
Choosing the "best" measure of center. Mean and median both try to measure the "central tendency" in a data set. The goal of each is to get an idea of a "typical" value in the data set. The mean is commonly used, but sometimes the median is preferred.
Step-by-step explanation:
Final answer:
To compare data sets, one must consider whether to use the mean or the median. The mean is suitable for symmetric, outlier-free distributions, while the median is better for skewed data or data with outliers.
Explanation:
Comparing Data Sets Using Measures of Center
When comparing data sets to understand the center, it's crucial to choose the most appropriate measure of center. The mean and the median are the two most common measures. The mean, which is the sum of all values divided by the number of values, is a great indicator of the center for symmetric distributions without outliers. In contrast, the median, which is the middle value in an ordered list, is robust to outliers and is better for skewed distributions.
To determine which measure to use, consider whether the data contain outliers or extreme values that could heavily influence the mean. If so, the median would be a better representation of the center. Moreover, the shape of the data set (symmetrical vs. skewed) and the presence of outliers or extreme values are crucial considerations. The median appears more suitable for skewed data sets, while the mean could be a more accurate measure for symmetric, outlier-free data.

Georgia is a farmer and wants to plant a crop of tomato plants so she can sell her crop at the local farmer's market. She already has a large number of plants cultivated from last year's harvest. Each should produce an average of 35 tomatoes per plant during the growing season. She has found a nursery to buy more tomato plants at which are a different type. She found that these tomato plants will cost $5.25 each and should produce 25 tomatoes per plant on average over the course of the growing season. When planting, she wants to arrange the plants so that there are 5 fewer plants in each column than there are in each row. Georgia can spend no more than $500 on the tomato plants. In order to meet customer demands, she needs to produce at least 5,000 tomatoes during the growing season. Let x represent the number of plants in a row, and let y represent the number of plants that Georgia already has. Create a system of inequalities to find the number of plants in a row and the number of plants Georgia already has, and use it to determine how many of the solutions are viable.

a. After four weeks, who has more money in the
who has more money in their savings account? Explain how you know.
b. after how many weeks will Andre and Elena have the same amount of money in their savings
accounts?
Andre saves more money than Elena after four weeks and after 6 weeks the savings of Andre and Elena is the same and this can be determined by forming the linear equation.
Given :
Andre and Elena are each saving money. Andre starts with $100 in his savings account and adds $5 per week.Elena starts with $10 in her savings account and adds $20 each week.Let w represents the total number of weeks. So, the linear equation that represents the situatuion "Andre starts with $100 in his savings account and adds $5 per week" is:
S = 5w + 100
The linear equation that represents the situatuion "Elena starts with $10 in her savings account and adds $20 each week" is:
S' = 20w + 10
a) After four weeks the savings of Andre is given by:
S = 5(4) + 100
S = 20 + 100
S = $120
After four weeks the savings of Elena is given by:
S' = 20(4) + 10
S' = 80 + 10
S' = $90
So, Andre saves more money than Elena after four weeks.
b) Now, the number of weeks after which the savings of Andre and Elena are the same is:
5w + 100 = 20w + 10
Simplify the above equation in order to determine the value of 'w'.
90 = 15w
w = 6
So, after 6 weeks the savings of Andre and Elena is the same.
