Answer:

21 questions were correctly answered

Step-by-step explanation:

If one scores an 84% on a quiz, that means that as an expression out of 100, a person has gotten 84 correct. To find how much the 84% equates to, one must convert the percent to a decimal. This means that one must divide the 84 by 100. After doing so, multiply the result by the number of questions on the quiz. The value attained will be the number of questions answered correctly.

Convert percent to decimal:

84% / 100 = 0.84

Multiply by the number of questions to find the amount answered correctly:

25 * 0.84 = 21

Answer:

21

Step-by-step explanation:

84% of 25 is 21

The maximum score is 100%, 100÷25= 4, meaning each question was 4 points or 4% of the total grade 84÷4=21 .

You walk through a used car lot and list the price and model year of each car you see determine whether the two variables are re
Blizzard [7]

Answer:

The narrative in the question can not be described as a function

Step-by-step explanation:

For the purpose of clarity, we will rephrase the question. The key point in the question  is to determine if the price and the model are related and if they fit into independent and dependent function.

Moving forward, to properly answer this question, it will be good for us to understand what dependent and independent functions are.

DEPENDENT FUNCTIONS: These are functions or can also be refereed to as variable that represents quantities or values whose parameter depends on how the independent variable is manipulated.

Example:

You are doing job to earn your a salary. For each project you do, you earn $10 dollar. In this case, the dependent variable is the amount of money you earn because the amount of money you earn depends on how many job or project you do.

INDEPENDENT FUNCTIONS: These are functions or can also be refereed to as variable that we have control over in the process of an event therefore, we are at liberty to manipulate it as we so wish as indicated in the dependent variable.

Going back to the narrative of the question, the narrative in the question can not be described as a function because the two identifies variables which are the price and the model years are been altered due to the fact that it is a used car lot so they have both lost their true value or worth. However, some might argue that price here is the independent function or variable while model year is the dependent variable.
