Looking at the table below, which answer best explains the data shown?

question 4 options:

this is a function because each output (y-value, range) is unique

this is a function because each input (x-value, domain) is matched to exactly one output (y-value, range)

this is a relation only because 4 is input twice and has 2 different output values

this is a relation only because each output value is unique

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

e) none of the above because the measure of angle cba is 101°
