Based on the number of people who had a car and the total number of people surveyed, the percentage is E. 64%
Percentage of those with carsThe percentage of students with a car is:
= Number of students with cars / Number of students in total x 100%

Juan graphed a line with a slope of −23 .
How does Juan count the slope from any point on the graph?
Answers
For Juan to count the slope from any point on the graph; he counts down 2 then right 3 to end up on the line again.
According to the question; the line which was graphed by Juan has a slope -2/3.
From linear mathematics, the slope of a graph is the change on its y-axis relative to that on its x-axis.The slope is given mathematically as;
m = (y2 - y1)/(x2 - x1)Therefore, since the slope of Juan's graph is -2/3
In essence, for every time the graph decreases by 2 units on the y-axis, the graph increases by 3 units on the x-axis.

If each shelf can hold at most 20 books, what is the least number of shelves needed to store the 175 books?
Answers
Answer- 9 shelves
In order to find out how many shelves are need we must divided 175 into 20. 175 divided by 20 is 8.75. But, because you cannot have have .75 of a shelf, you have to round this to a whole. This means that 9 shelves will be the least needed number of shelves need to store 175 books. To check this answer 20 books X 8 shelves is 160 books, which means eight shelves can only store 160 books, we will need and additional shelf to store the last 15 books.

Make a table in which you list all possible outcomes of rolling two dice. Call the dice A and B
A). What is the probability of rolling a 7.00? You can give the probabilities as fractions, such as 3/36.
B). What is the probability of any double?
C). What is the probability of rolling a 7.00 or an 8? You can give the probabilities as fractions, such as 3/36.
Answers
The probabilities when two dice are rolled are given as follows:
a) Rolling a 7: 1/6.
b) Any double: 1/6.
c) Rolling a 7 or an 8: 11/36.
How to calculate the probabilities?The probabilities are calculated with the division of the number of desired outcomes by the number of total outcomes.
The 36 total outcomes when two dice are rolled are given as follows:
(1,1), (1,2), (1,3), (1,4), (1,5), (1,6)(2,1), (2,2), (2,3), (2,4), (2,5), (2,6)(3,1), (3,2), (3,3), (3,4), (3,5), (3,6)(4,1), (4,2), (4,3), (4,4), (4,5), (4,6)(5,1), (5,2), (5,3), (5,4), (5,5), (5,6)(6,1), (6,2), (6,3), (6,4), (6,5), (6,6)The desired outcomes for rolling a seven are given as follows:
(1,6), (2,5), (3,4), (4,3), (5,2), (6,1). -> six outcomes.
Hence the probability of rolling a seven is of:
p = 6/36 = 1/6.
The doubles outcomes are given as follows:
(1,1), (2,2), (3,3), (4,4), (5,5), (6,6) -> six outcomes.
Hence the probability of rolling any double is of:
p = 6/36 = 1/6.
The outcomes in which a seven or an eight are rolled are given as follows:
Seven: six outcomes, already obtained.Eight: (2,6), (3,5), (4,4), (5,3), (6,2) -> five outcomes.Hence the probability is of:

Which of the following statements best describes the function of the logic variable X?
A. X is a variable whose value is 1 or 0.
B. X is a constant value in the indeterminate range of logic values.
C. X is a variable whose value is always 1.
D. X is a variable whose value is always 0.
Answers
The best statement that describes the function of the logic variable X is: A. X is a variable whose value is 1 or 0.
Logic variables typically represent binary states or conditions, where 1 represents "true" or "on" and 0 represents "false" or "off". Therefore, option A accurately describes the function of the logic variable X as having a value of either 1 or 0. Logic variables are often used in the field of logic and computer science to represent binary states or conditions. The value of a logic variable can only be one of two possibilities: 1 or 0.
In this context, 1 typically represents "true" or "on," indicating that a certain condition is satisfied or a certain state is active. On the other hand, 0 represents "false" or "off," indicating that the condition is not satisfied or the state is inactive.
By using logic variables, we can model and manipulate binary logic in a precise and systematic manner. The values of logic variables are fundamental in logical operations, such as AND, OR, and NOT, which are essential in designing and analyzing digital circuits, programming, and logical reasoning.

Examples of substantive procedures include observation, where auditors directly witness a process or activity, such as counting physical inventory. Inquiry involves seeking information from management or other personnel regarding financial transactions or events. Confirmation refers to the direct communication with third parties, such as banks or customers, to verify the accuracy of reported balances or transactions.
Other examples of substantive procedures include analytical procedures, inspection of records and documents, and reperformance of calculations or controls. Therefore, all answer choices (A. observation, B. inquiry, C. All of these answer choices are correct, and D. confirmation) are valid examples of substantive procedures in auditing.

Answers
Answer:
P=5 and Q=-3
Step-by-step explanation:
-3+8=p=5
4-7=q=-3
<p, q>= <5,-3>
The composition of the translations; T < − 3 , 4 > ⋅ T < 8 , − 7 > (x, y) as one translation gives;
T < 5 , − 3 > (x, y)
We want to compose the translations; T < − 3 , 4 > ⋅ T < 8 , − 7 > (x, y) as one translation;
Now, translation is usually a map defined as;
T < a , b> < x , y> = (x + a, y + b)
Thus, the image of the first translation is given as;
T < 8 , − 7 > (x, y) = (x + 8, y - 7)
Finally;
T < − 3 , 4 > ⋅ T < 8 , − 7 > (x, y) = T < − 3 , 4 > ⋅ (x + 8, y - 7)
⇒ (x + 8 - 3, y - 7 + 4)
⇒ (x + 5, y - 3)
Since T < a , b> < x , y> = (x + a, y + b)
Then; (a, b) = (5, -3)
As one translation gives;

a. If the study that was used to collect the data were to be repeated 100 times, then we would obtain data similar to the data collected in about 4 of the studies if the null hypothesis is true. b. The probability that the null hypothesis is true is 4.1% c. The probability that the alternative hypothesis is true is about 96%. d. If the alternative hypothesis is true then the chances of obtaining data like the observed data is 4.1% e. This p-value is less than 5% therefore the alternative hypothesis must be true.
Answers
The correct interpretation of a p-value of 0.041 is option a: If the study that was used to collect the data were to be repeated 100 times, then we would obtain data similar to the data collected in about 4 of the studies if the null hypothesis is true.
The p-value is a measure of the evidence against the null hypothesis in a statistical hypothesis test. It represents the probability of obtaining results as extreme as, or more extreme than, the observed data, assuming that the null hypothesis is true.
In this case, a p-value of 0.041 means that if the null hypothesis is true, and the study were to be repeated 100 times, we would expect to obtain data similar to the observed data in about 4 of those studies. It indicates that the observed data is somewhat unlikely under the assumption of the null hypothesis.
It's important to note that the p-value does not directly provide information about the probability that the null hypothesis or the alternative hypothesis is true. It simply measures the strength of evidence against the null hypothesis based on the observed data.
Therefore, the correct interpretation is that if the study were repeated 100 times, we would expect to see data similar to the observed data in about 4 of those studies, assuming the null hypothesis is true.

Roger can earn $510 at most.
Step-by-step explanation:

Which gives the earnings of Roger when he sells v videos. Since the play’s audience consists of 230 people and each one buys no more than one video, v can take values from 0 to 230, i.e.

That is the practical domain of E(v)
If Roger is in bad luck and nobody is willing to purchase a video, v=0
If Roger is in a perfectly lucky night and every person from the audience wants to purchase a video, then v=230. It's the practical upper limit since each person can only purchase 1 video

Hello there. To graph this function, the best way is to find two points that are into the line and then pass a line through them.
Since the image of a line is all the real numbers, we can pick any point for x and find y that satisfy it.
Starting with x = 0, we have that f(0) = -3 * 0 + 4 = 4.
So the point (0, 4) is in the line.
Now, making x = 1, we have that f(1) = -3 * 1 + 4 = -3 + 4 = 1
