Vilka [71]3 years ago
5 0

Answer:

20 questions.

Step-by-step explanation:

Let  x  be the number of questions on the quiz.

85 %  means  85  out of  100  (or  85/ 100  )

85/ 100   = 3/x

--->100-85=15

--->15/3=5

--->100/5=20  

Meaning each question was worth 5% and there were 20 questions.

Answer:

First, second, third, and fourth are functions

Step-by-step explanation:

Each input in the first, second, third, and fourth only have one output. In the fifth one 3.3 and 6.6 are seen twice as the x-value, so this is incorrect.

(answered this on your other question, but I will put it here too!)

Cada entrada en la primera, segunda, tercera y cuarta tiene solo una salida. En el quinto, 3.3 y 6.6 se ven dos veces como el valor de x, por lo que esto es incorrecto.

(respondí esto en tu otra pregunta, ¡pero también lo pondré aquí!)

Is the following relation a function?<br><br> X Y<br> 6 -1<br> -1 2<br> 4 3<br> 0 3
german
Answer: Given relation is a function

A relation is said to be a function if no value in its domain is paired up with more than one value in its range.

Since x values represent the Domain of a relation and y values represent the Range of a relation, in terms of x and y we can say:

A relation is said to be a function if an x-value is not paired up with more than one y-value.

From the above table we can see that all the x values are distinct, so no x value is paired with more than one y-value and thus given relation is a function.
