Answer:
Step-by-step explanation:
<u>Let the score is x. The average is:</u>
- (83 + 56 + 94 + x)/4 = 82
- x + 233 = 4*82
- x = 328 - 233
- x = 95
To square means to multiply something by itself. A variable is a letter such as x. So a squared variable=x×x=x^2.
I hope that helped.
Yes, you are correct, it is A!
Recall the pencil line test, which is where you go across the x axis (the graph horizontally) and see if the pencil touches any two points at the same time. If it does, then the graph is not a function.
Point being: since question a has a bunch of y values on top of one x value, the pencil would inevitably touch multiple at the same time, hence why it is easy to tell that it is not a function! Hope this helps :)
