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.

If Neil Works 3/4 of an hour on Monday and 6/10 of an hour on Tuesday how much time will she work altogether?
jek_recluse [69]

Answer:

C

Step-by-step explanation:

3/4 + 6/10

Find a common denominator and find what you multiply to each denominator to get that number and multiply the numerator by the same amount

(3/4 * 5/5) + (6/10 * 2/2)=

15/20 + 12/20

Then add

15/20 + 12/20= 27/20

Then finally convert to mixed number

27/20 = 1 7/20
