The biggest rule for functions in a table is that none of the numbers in the X column are repeating. But for the Y column, it is okay to have repeats.

When you look at the answer choices, you could eliminate B, C, and D because of repeats in the x column.

A IS A FUNCTION because all the numbers in the x column are different

B is NOT A FUNCTION because in the x column, there are 2 3's

C is NOT A FUNCTION because in the x column, there are 2 -5's and 2 -10's

D is NOT A FUNCTION because there are 2 20's

Your answer would be A.

anastassius [24]

Answer:

Value of y = 7

Step-by-step explanation:

By the midpoint theorem of the triangles,

"Segment joining midpoints of the two sides of a triangle is parallel to the third side and measure half the length of the third side."

Therefore, from the figure attached,

In ΔFGH,

J and K are the mid points of the two sides GH and FH.

By theorem, segment JK║GF and m(JK) = $\frac{1}{2}m(FG)$

$(2y+5)=\frac{1}{2}(5y+3)$

(5y + 3) = 2(2y + 5)

5y + 3 = 4y + 10

5y - 4y = 10 - 3

y = 7

andrew11 [14]

Answer:

1/20 of the patrons at Joe's restaurant are expected to be male and out of town.

Step-by-step explanation:

1. Let's review all the information provided for solving this question:

Proportion of patrons that are male at Joe's restaurant = 1/4

Proportion of patrons that are from out of town at Joe's restaurant = 1/5

2. What proportion would you expect to be male and out of town?

For finding the proportion of the patrons, that would be male and that would be from out of town, we do this calculation:

Proportion of patrons that are male at Joe's restaurant * Proportion of patrons that are from out of town at Joe's restaurant

1/4 * 1/5 = 1/20

It means that 1/20 of the patrons at Joe's restaurant are expected to be male and out of town.
