A teacher gave a test to three classes that contained 27, 25, and 23 students. A total of 18 students scored an A on the test. B

salantis [7]

Ratio of classes A, B, C = 4 : 6 : 5, respectively
4 + 6 + 5 = 15
So, class A represents 4/15 of the TOTAL population
Class B represents 6/15 of the TOTAL population
Class C represents 5/15 of the TOTAL population

So, weighted average of 3 groups combined = (4/15)(65) + (6/15)(80) + (5/15)(77)
= 260/15 + 480/15 + 385/15
= 1125/15
= 75

Do the ordered pairs below represent a relation, a function, both a relation and a function, or neither a relation or a function

tangare [24]

Answer:

Is a relation and a function.

Step-by-step explanation:

Every set of order pairs represent a relation.

Remember that a relation is a function when every element from the domain has a unique corresponding element in the range. In this case

f(-2) = 3

f(2) = 7

f(7) = -12

f(10) = -15

Therefore the relation is a function as well.
