Answer:

The total number of students that ate lunch are 300 .

Step-by-step explanation:

Formula

Percentage = \frac{Part\ value\times 100}{Total\ value}

As given

There are 4 lunch choices in a school cafeteria: Salad, Pizza, Spaghetti, and Sub Sandwiches.

The percentage of students that chose salad is 15%.

If 45 students chose salad.

Here

Percentage = 15%

Part value = 45

Put in the formula

15 = \frac{45\times 100}{Total\ value}

Total\ value= \frac{4500}{15}

Total\ value= 300

Therefore  the total number of students that ate lunch are 300 .

Is the following graph a function
daser333 [38]
You can use the vertical line test to determine if the graph is a function.

A function must: for every x value have only one y value.

Vertical line test: if you draw a bunch of vertical lines each line only touches the graph once.

So a circle would not be a function, or a horizontally facing parabola, etc... Remember, if you draw a vertical line "|" and it touches the graph more than once at any point then it is not a function.

Now take a look at the graph in the question.
In this graph if we do the vertical line test there are no place where a vertical line touches the graph twice so this graph is indeed a function.

This means your answer is C. Yes
