Step-by-step explanation:

The individual scores in the data are represented by frequency denoted by f column. f column depicts that how many times the individual scores are occurring in the data set. Hence to calculate the amount of individual score in the data set we simply add all frequencies. n=sum of f=2+4+1+3=10. Hence there are 10 individual scores present in the entire data set.

The number of individual scores in the given frequency distribution set is 10, obtained by adding the frequencies together.

In the given question, it's the frequency distribution that is given with scores X: 5, 4, 3, and 2 with their respective frequencies f: 2, 4, 1, and 3. To find the total number of individual scores in the entire set, you simply sum up all the frequencies. So, 2+4+1+3 equals 10. So, the number of individual scores in the entire set is 10. Hence, the correct answer is c. N = 10.

Step-by-step explanation:

A is on the line QA', which is 1.25+1.25 = 2.50 units long*. Thus the scale factor is ...

  QA'/QA = 2.50/1.25 = 2

The scale factor is 2.

_____

* There are two points on the line QA that are 1.25 units from A. One of them is point Q. If A' is coincident with Q, then the scale factor is 0, and line segment A'B' is the single point Q. We don't believe that is intended to be the case, so we assume that point A' is farther along AQ, hence 2.5 units from Q.

Given:

$ 1.50 / gallon

1 gallon = 28 miles;

Solution:

$ 24.00 / $ 1.50 = 16 gallons

16 gallons x 28 miles = 448 miles

have a nice day:)

Answer:they would drive 448 miles if they spend $24 on gasoline

Step-by-step explanation:

The Morrison’s car uses one gallon of gasoline for every 28 miles. If gasoline costs $1.50 per gallon, then the cost of driving 28 miles would be $1.5.

Therefore, the number of miles can they drive if they spend $24 on gasoline would be

(28 × 24)/1.5 = 448 miles

The function that represents the number of math problems solved in a class is given by ????(x, y) = (15/7)* x / y, where x represents time and y represents the number of student questions. The constant of variation 'k' is 15/7.

Given that the number of math problems solved (????) in class is influenced by time duration (x) and the number of student questions (y), we can infer a relationship. We can define a constant of variation (k), which stands for the number of problems solved per time unit and per question. Based on the provided situation where 5 problems were solved in 6 minutes with 14 questions, we calculate k as k = ????(x/y) = 5(6/14) = 30/14 = 15/7.

Therefore, the function that represents this scenario is ????(x, y) = (15/7)* x / y, where x is the length of time and y is the number of student questions.

Answer:

"≥"

Step-by-step explanation:

1) Well, for the sake of clarity we'll use a circle on a number line to represent the point solution of each inequality.

2) Writing the system:

[tex]\left\{\begin{matrix}y\geqslant 3x&\\x\geqslant-2&\end{matrix}\right.[/tex]

3) We'll shade the circles and use "≥"

Final answer:

The correct inequality symbols that could be written in both circles for the system 'y 3x x –2' are '<=' and '>=', representing the relationships 'y <= 3x' and 'x >= -2' respectively.

Explanation:

To represent the given system of inequalities algebraically, one needs to identify the correct inequality symbols that could be used between the variables x and y. These symbols articulate the ordering and relationship between these variables.

Given the statement of the system 'y 3x x –2', the inequality symbols that could fit in the circles to complete the system algebraically could be '<=' for 'y <= 3x' and '>=' for 'x >= -2'. This means '<=' and '>=' are both inequality symbols that could be written in the circles to represent the relationship between the variables according to the rules of inequalities which define x is less than or equal to y (x <= y), and x is greater than or equal to y (x >= y).

Inequalities allow us to compare relative sizes or orders of numbers and to solve various algebraic problems dealing with quantity and relationships.

Answer:

384 lamps

Step-by-step explanation:

This is simply a multiplication problem. From the question, we know that each fixture needs 4 lamps with a single room needing 16 fixtures.

The number of lamps required by each room is thus 16 * 4 = 64 lamps

Now, the total number of lamps required by 6 rooms is thus 64 * 6 = 384 lamps

To find the total number of lamps required for 6 rooms, multiply the number of fixtures per room by the number of rooms, then multiply the result by the number of lamps per fixture.

To find the total number of lamps required for 6 rooms, we need to first determine the number of fixtures in 6 rooms. Since each room requires 16 fixtures, the total number of fixtures in 6 rooms would be 16 x 6 = 96 fixtures.

Each fixture requires 4 lamps, so to find the total number of lamps required for 96 fixtures, we multiply 96 x 4 = 384 lamps.

Therefore, 384 lamps will be required for 6 rooms.

Final answer:

To find the three-digit number with the tens digit being 5 and the number increasing by 495 when the hundreds and ones digits are switched, set up an equation using placeholders for the hundreds and ones digits, solve the equation to find these digits, and deduce the original number, which is 459.

Explanation:

The question involves finding a three-digit number based on given conditions about digits and their positions. We know that the tens digit is 5. If we switch the hundreds and the ones digits, the number increases by 495. This implies that the ones digit must be less than the hundreds digit, as switching them results in a larger number. Let's denote the hundreds digit by 'a' and the ones digit by 'c'.

The original number can be represented as 100a + 50 + c, and after switching, the number becomes 100c + 50 + a. The problem states that the latter is 495 units larger than the original number. So, we can set up the following equation:

100c + 50 + a = (100a + 50 + c) + 495

Simplifying the equation gives us:

99c - 99a = 495

This simplifies to:

c - a = 5

Since 'a' and 'c' are digits, the only possibility is that a = 4 and c = 9. Therefore, the original number is 459.

Final answer:

The total price of the car including DMV fees of 1.25% is (B) $17,516.25, which is found by adding the DMV fees of $216.25 to the purchase price of $17,300.

Explanation:

The question asks for the total price of a car including DMV fees, which are 1.25% of the purchase price of the car after sales tax.

To find the DMV fees, first convert the percentage to a decimal by dividing 1.25 by 100, which gives us 0.0125. Then multiply the purchase price after sales tax, $17,300, by 0.0125 to get the DMV fees.

The calculation is: $17,300 x 0.0125 = $216.25.

Finally, add the DMV fees to the purchase price to get the total price: $17,300 + $216.25 = $17,516.25. Therefore, the correct answer is B. $17,516.25.

Given:

From the graph, we can conclude that:

The function has vertical asymptotes at [tex]x=-3\ and\ x=2[/tex]

The function has horizontal asymptote at [tex]f(x)=0[/tex]

Vertical asymptotes are those values of 'x' for which the functions tends towards infinity. Horizontal asymptote is the value of the function as the 'x' value tends to infinity.

Now, as [tex]x \to -3^{+}[/tex] means the right hand limit of the function at [tex] x=-3[/tex]

From the graph, the right hand limit is the right side of the asymptote of the function at [tex] x = -3[/tex]. The right side shows that the function is tending towards negative infinity.

Answer:

C

Step-by-step explanation:

since the camper gets old we will choose decay factor over the years and since t is in years in the explanation so t in the expression means years as well

The expression describes the initial value of the camper multiplied by its annual decay factor raised to the power of the number of years since purchase, corresponding to option C.

The expression 22,475(0.81)^t best describes the product of the initial value of the camper and its decay factor raised to the number of years since it was purchased. The correct choice that describes the expression is C. The initial value of the camper is given as $22,475. The factor 0.81 represents the annual depreciation rate, meaning that the camper loses 19% of its value each year (100% - 81% = 19% decay). The variable t stands for the number of years since the purchase. Therefore, each year, the value is multiplied by 0.81, repeatedly, to reflect the continuous decrease in value.
