They are often called formulas.
They mostly use words.
They often describe real-world relationships.
They are hardly ever used.

Answers

Answer 1
Answer:

The correct answers are:


They consist primarily of variables.

They are often called formulas.

They often describe real-world relationships.


Explanation:


Literal equations are defined as "equations in more than 1 variable whose variables represent specific quantities."


This means that literal equations consist mostly of variables.


Since the variables represent specific quantities, this means they typically represent real-life situations.


Since they represent real-life situations, these equations are often formulas for things in the real world (such as area, volume, perimeter, circumference, etc.)
Answer 2
Answer: The literal equations are those which made use primarily of variables to represent known values. These equations allow the use of variables instead of the true distance, time, slope, interest, etc. With literal equations, we are often asked for the value of one of the variables in terms of the other. Hence, the answer to this item is the first and the second one.

The protractor on the top left has an arrow halfway inbetween 50° and 60, making the angle 55°.

Therefore, the answer is Figure A.

The scatter plot represents the purchase prices and selling prices of X-ray machines made by five different manufacturers. Which of the following points show errors of prediction or residuals?Answer Choices :
Points (14, 25) and (15, 25)
Points (15, 25) and (18, 26)
Points (14, 25) and (16, 25)
Points (12, 24) and (18, 26)

Answers

The points on the scatter plot show the different predictions. The straight line drawn is called the line of regression. Errors in prediction for each point can be determined by drawing a vertical line from the point to the line of regression. As seen in the image, all of the prediction points are found on the line except for points (14,25) and (16,25). Therefore, these points contain errors in prediction.

Answer:

As seen in the image, all of the prediction points are found on the line except for points (14,25) and (16,25). Therefore, these points contain errors in prediction.

(02.03 MC) The temperature at a mountain base camp was −2 degrees Celsius on Thursday. Friday morning, the temperature was 1 degree Celsius lower than it was on Thursday. By Friday evening, the temperature was 3 degrees Celsius lower than it was that morning. What was the temperature at the base camp Friday evening? (1 point) −9 degrees Celsius −8 degrees Celsius −7 degrees Celsius −6 degrees Celsius

Answers

Answer:

The temperature at the base camp Friday evening is - 6 degrees Celsius.

Step-by-step explanation:

To get the temperature at a mountain base camp on Friday evening, we must translate statement into a mathematical form:

(i)The temperature at a moutain base camp was - 2 degress Celsius on Thursday:

T_(o) = -2\,^(\circ)C

(ii)Friday morning, the temperature was 1 degree Celsius lower than it was on Thursday:

\Delta T_(1) = -1\,^(\circ)C

(iii)Friday evening, the temperature was 3 degrees Celsius lower that it was that morning:

\Delta T_(2) = -3\,^(\circ)C

The temperature at the base camp Friday evening is:

T = T_(o)+\Delta T_(1)+\Delta T_(2)

T = -2\,^(\circ)C-1\,^(\circ)C-3\,^(\circ)C

T = -6\,^(\circ)C

The temperature at the base camp Friday evening is - 6 degrees Celsius.

Answer:

D) -6 degrees Celsius
