Answer:

128 degrees, so C is again the answer.

Step-by-step explanation:

According to the scatterplot below, which statement is correct?
FinnZ [79.3K]

Answer:

Hey there

Step-by-step explanation:

The input, or independent variable, is years in operation.

Step-by-step explanation:

In an ordered pair (x, y),  the independent variable or input is x  and y is the dependent variable or the output.

Therefore, the values on x-axis determine the results or output on y-axis.

The ordered pairs (x, y) are:

(1, 11)     ⇒  there are 11 enrollees on Year 1

(2, 33)   ⇒  there are 33 enrollees on Year 2

(3, 39)   ⇒  there are 39 enrollees on Year 3

(4, 58)   ⇒  there are 58 enrollees on Year 4

(5, 85)   ⇒  there are 85 enrollees on Year 5

Where:

x are values on the x-axis that refers to number of years in operation

y are values on the y-axis that refers to the corresponding numbers of enrollees for each year.

Even without the graph, the correct statements i:

The input, or independent variable, is years in operation.
