Identify the type of data (qualitative/quantitative) and the level of measurement for the following variable. Explain your choic

AleksAgata [21]

Answer:

Option C. Quantitative, because numerical values, found by either measuring or counting, are used to describe the data.

Step-by-step explanation:

We are given the following in the question:

Variable: Final exam scores (from 0 to 100) for graduating high school seniors.

The following variable is a quantitative variable.

Quantitative variable:

Their values are expressed in numerical.
They are either measured or counted.
Descriptive terms are not used to describe them.
They can either be continuous or discrete.

Since final scores have numerical values and are counted, they are quantitative variables.

Option C. Quantitative, because numerical values, found by either measuring or counting, are used to describe the data.

Level of measurement:

A score of zero means no true existence for score. That is true zero exist.

Thus, it is ratio because difference between the values in data can be compared meaningful and they have a true zero.

Question 2(Multiple Choice Worth 1 points) (06.01) Solve 2x + 5y = −13 3x − 4y = −8 (4, 1) (−4, 1) (4, −1) (−4, −1)

dlinn [17]

ANSWER

The solution is
$(-4,-1)$

EXPLANATION

The given equations are:

$2x + 5y = - 13...(1)$

and

$3x - 4y = - 8...(2)$

We multiply equation 1 by 3 to get,

$6x + 15y = - 39...(3)$

We multiply equation 2 also by 2 to get,

$6x - 8y = - 16...(4)$

We subtract equation 4 from equation 3 to get,

$23y = - 23$
This implies that,

$y = - 1$

We put this value of y into any of the equations say equation 2

$3x - 4( - 1) = - 8$
Simplify

$3x + 4 = - 8$
Group like terms
$3x = - 8 - 4$
Simplify,

$3x = - 12$

Divide both sides by 3 to get,

$x = - 4$

Therefore the solution is
$(-4,-1)$

The correct answer is option D.
