The domain and range of the graph above in interval notation include the following:

Domain = [-6, 3]

Range = [-3, 3]

In Mathematics and Geometry, a domain refers to the set of all real numbers (x-values) for which a particular function (equation) is defined.

In Mathematics and Geometry, the horizontal portion of any graph is used to represent all domain values and they are both read and written from smaller to larger numerical values, which simply means from the left of any graph to the right.

By critically observing the graph shown in the image attached above, we can reasonably and logically deduce the following domain and range:

Domain = [-6, 3] or -6 ≤ x < 3.

Range = [-3, 3] or -3 < y < 3

Answer:

Kindly check explanation

Step-by-step explanation:

Given :

Lewis :

y = 17x

x = number of hours worked

y = amount of money earned

Carl:

Carl’s Earnings Time (h) 3 5 8 10

Money earned ($) 45 75 120 150

(a) How much money does Carl earn per hour? Show your work on how you found the constant of proportionality for both.

Money earned = pay per hour * hours worked

$45 = pay per hour * 3

Pay per hour = $45 / 3 = $15

Hence, Carl's earning per hour = $15

(b) Who earns more per hour? Justify your answer by comparing the two. Please use complete sentences.

Lewis : y = 17x

Carl : y = 15x

Where $17 and $15, represents Lewis and Carl's hourly pay respectively.

Hence, Carl earns more.

(c) Draw a graph that represents Carl’s earnings over time in hours. Remember to label the axes with the real world quantities that x

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

Given data as:

Charges for Go Golf -

Renting a ball and a club costs $2.50.

$4.25 for one game and

Charges for Golf Games -

3.25 for the rental of a ball and a club

$8.50 for two games

We have to determine the number of games would the cost be the same.

Total charges of Go golf per game = $2.50 + $4.25 = $6.75

Total charges of Golf game for 2 games = $3.25 + $8.50  = $11.75

For per game = $11.75 / 2 = $5.875

Let the game would be x for  Go golf and

And let game would be y for the golf game

As per the given condition,

6.75 x = 5.875y

27/4 x = 47/8 y

Apply cross multiplication operation,

54x = 47y

x/y = 47 / 54

x = 47

So y = 54.

Hence, the cost would be the same for 47 Go golf and 54 golf games.

Answer:

so here we minus 5 from 255 to get to 250 and we do it again to get to 245. for reaching the 40th term we should do it 39 times.

so, 255+ (-5) (39) = 255 - 195 = 60

which is our 40th term.

The 40th term of  (255, 250, 245...) is 60.

Calculations :

The formula to find the nth term = \(a_{n}\)  =  -5n + 260

                                                      = \(a_{40}\) x 5n = 260

​I'm putting all my savings into stocks because stocks always outperform other types of investments over the long term.

Choose the correct answer below.

A.  The statement does make sense because stocks historically outperform bonds and cash over the long term and investing in stocks is​ high-risk, which offers higher returns.

B.  The statement does not make sense because although stocks historically outperform bonds and cash over the long​ term, investing in stocks is​ high-risk and there is no guarantee that the investment will yield a high return.

C.  The statement does make sense because stocks are a​ low-risk investment, offering predictable low returns.

D.  The statement does not make sense because stocks never outperform bonds and cash over the long term.

Answer:

B.  The statement does not make sense because although stocks historically outperform bonds and cash over the long​ term, investing in stocks is​ high-risk and there is no guarantee that the investment will yield a high return.

Step-by-step explanation:

Of course, the statement does not make sense because it does clearly say the reality about stocks. By saying "stocks always outperform" other investment types it hides the possibility of losses from stock investments.

For example, a company's stock may be negatively affected as a result of employee layoffs or unexpected company scandals. Hence, there is no guarantee that the investment will yield a high return.

The range of function is values on the y-axis: R=[-7,2].

A function is a mathematical concept that describes the relationship between two sets of numbers. It is a rule that assigns to each input (or element in the domain) exactly one output (or element in the range). In simpler terms, a function is like a machine that takes in a number and produces another number as output, according to some specific rules. The input is usually denoted by x, and the output by f(x), which is read as "f of x". Functions can take many forms, such as linear, quadratic, trigonometric, exponential, logarithmic, and more. They are widely used in mathematics, science, engineering, and many other fields to model and analyze various phenomena.

Here,

To find the range of a function, you need to determine all possible output values of the function. Start by identifying the function's domain, which is the set of all possible input values of the function. Once you know the domain, apply the function to each input value in the domain and record the corresponding output values. Once you have a list of output values, identify the smallest and largest values in the list. These values represent the range of the function. For example, consider the function f(x) = 2x + 1. The domain of this function is all real numbers.

To find the range, apply the function to several input values in the domain:

f(-3) = -5

f(-2) = -3

f(-1) = -1

f(0) = 1

f(1) = 3

f(2) = 5

f(3) = 7

These output values give us a set of possible output values, which are {-5, -3, -1, 1, 3, 5, 7}. The smallest value in the set is -5 and the largest value is 7, so the range of the function is [-5, 7].

Note that for some functions, it may be difficult or impossible to find the exact range. In such cases, you can use techniques such as graphing or calculus to estimate the range.

Counting these numbers, we find that there are 17 students who obtained more than 45 marks.

b) To find the number of students getting less than 45 marks, we count the students whose marks are less than 45 in the given list.

In the given list, the students with marks less than 45 are: 44, 44, 42, 41, 41, 42, 41, 44, 44, 42, 45, 45, 45, 44, 45.

Counting these numbers, we find that there are 15 students who obtained less than 45 marks.

c) To find the maximum number of students getting the same marks, we look for the mark that appears most frequently in the given list.

In the given list, the marks obtained by the students are: 44, 50, 44, 49, 42, 47, 45, 42, 44, 48, 49, 48, 47, 49, 47, 41, 45, 48, 41, 48, 41, 42, 47, 49, 49, 48, 50, 47, 49, 48, 46, 44, 45, 45, 46, 44, 42, 47, 48, 45.

Counting the frequency of each mark, we find that the marks 47 and 48 appear most frequently, with a count of 6 each. Therefore, the maximum number of students getting the same marks is 6.

d) To find the average marks obtained by the students in the class, we sum up all the marks and divide by the total number of students.

Total marks = 44 + 50 + 44 + 49 + 42 + 47 + 45 + 42 + 44 + 48 + 49 + 48 + 47 + 49 + 47 + 41 + 45 + 48 + 41 + 48 + 41 + 42 + 47 + 49 + 49 + 48 + 50 + 47 + 49 + 48 + 46 + 44 + 45 + 45 + 46 + 44 + 42 + 47 + 48 + 45

           = 1912

Total number of students = 40

Average marks = Total marks / Total number of students

                 = 1912 / 40

                 = 47.8

Therefore, the average marks obtained by the students in the class is 47.8.

Answer:

$28 per hour

Step-by-step explanation:

Let's first find out how much extra Victoria was paid during the week she worked overtime.

Without overtime, Victoria's weekly paycheck would be $550. However, she received $690 that week. The difference between the two amounts is the extra pay for overtime:

Extra pay = Total pay - Regular pay = $690 - $550 = $140

Now, we know that Victoria worked 5 hours of overtime. To find her overtime pay per hour, we can divide the total overtime pay by the number of overtime hours:

Overtime pay per hour = Total overtime pay / Overtime hours = $140 / 5 = $28

Victoria's overtime pay is $28 per hour.

Hope this helps!

Answer:

Victoria is paid $28 per hour of overtime.

Step-by-step explanation:

Get the difference of Victoria's paycheck with and without overtime.

Difference = $690 - $550

Difference = $140

The difference is the amount that she was paid for the overtime.

Since she worked for 5 hours then we can just divide the amount over the time.

Rate = $140/5hours

Rate = $28/hr
