Yes the table represents a function because it go up by 10 on the x-values and 200 in the y-values.

Answer:

Step-by-step explanation:

There is only one answer. It is the very definition of what a function is.

The answer is A. That is exactly how a function is defined.

You can have minus numbers and still have a function. B is incorrect.

A function should have different x values. If the sample doesn't have different x values but different y values, you don't have a function C is wrong.

D is wrong. You can have a function if all the y values are different. The x values normally should be as well.

The student council is hosting a drawing to raise money for scholarships. They are selling tickets for $9 each and will sell 500
ryzh [129]

Answer:

-$2.32

Step-by-step explanation:

Give that

The selling price per ticket is $9

And the number of tickets sold is 500

So,

There is one grand prize, three $300 second prize, and eleven $40 third prizes

We need to find out the expected value of the profit

= \frac{1}{500} \times 2000 +  \frac{3}{500} \times 300 + \frac{11}{500} \times 40\\\\

= 4 + 1.8 + 0.88

= 6.68

Now the expected profit is

= $6.68 - $9

= -$2.32

Can someone help me understand this question?
JulijaS [17]
Hey there! 

For Part A, because the amount earned on Sunday isn't specified, we can call this additional income x. Because we're writing an expression, we don't need an equal sign. The expression will be (x + 14). 

For Part B, "2 less than" will mean "– 2" and "twice than" will mean the amount of dogs that Alicia walked times 2. We can call the amount that Alicia walked y to avoid confusion with the last expression (though you could use whatever variable here) and your expression will be (2y – 2). 

Hope this helped you out! :-)
