The required equation based on the information given is y =0.433x + 24.493

<h3>How to illustrate the information?</h3>

It should be noted that one can simply copy and paste the data set into excel sheet

Then, use intercept and the slope formula to find slope and intercept. We will have

slope = SLOPE(y values, x values)

= 0.433

intercept = INTERCEPT(y values, x values)

= 24.493

Therefore, the required equation is y =0.433x + 24.493

A manufacturer buys large quantities of certain fuel pumps. He finds that his cost depends on the number of cases, q, bought at
ruslelena [56]

Answer:

The correct option is <u>c) $17.50/case</u>.

Step-by-step explanation:

Note: The data in the question are merged. The data are therefore sorted and the whole question is represented before answering the question. Please, see the attached pdf file for the sorted data and the represented question.

The explanation of the answer is now given as follows:

Marginal cost refers to the cost incurred in order to produce one more unit of a product.

Therefore, marginal cost is the change in the total cost that is caused by a one-unit increase in the quantity of a commodity that is produced.

From the table in the question, the marginal cost at q = 108 can be calculated as follows:

Change in total quantity at 180 cases = 108 - Number of cases immediately before 108 = 180 - 104 = 4

Change in total cost at 180 cases = Total cost at 108 cases - Total cost immediately before 108 cases = 1990 - 1920 = 70

Marginal cost at 108 cases = Change in total cost at 180 cases / Change in total quantity at 180 cases = 70 / 4 = 17.50 per case

Therefore, the correct option is <u>c) $17.50/case</u>.

The art club is designing a rectangular mural for the school hallway. Three
AysviL [449]

Answer:

The coordinates are (50, 103)

Step-by-step explanation:

The three hallways are AB, BC, CD.

The co-ordinate of D is (50, 75).

The school's flagpole is 28 meters right of the point D.

Hence the y-coordinate for the flagpole will be same as D, that is 75.

The x-coordinate will be (28 + 75) = 103.

The location of the school's flagpole will be represented by (50, 103)

Which conjunction is disjunction is equivalent to the given absolute value inequality? |x+2|&lt;18
a_sh-v [17]

Answer:  conjunction and  -20<x <16 is answer.


Step-by-step explanation:

It is a conjunction because it is and statement

|x+2|<18 gives  

[Since  l x-a l <b means x-a lies between -b and b ]

-18<x+2<18

subtracting 2 in the whole  inequality ,we get

 -18-2 <x +2-2 < 18-2

   -20 < x < 16
