There is a rule for functions:

One input(x-value) can only have one output(y-value).

If one input has more than one output, it is not a function.

(This doesn't apply to outputs, one output can have more than one input and still be a function)

This graph shows a set of ordered pairs that does NOT represent a function because there are two points on x = -3. The input -3 has more than one output of -4 and 4, so it is not a function.

alice has eight good behavior stars and earns a new one each week. Mack has two good behavior stars and earns two new ones each

IRINA_888 [86]

Answer:

In 14 weeks will they have the same number of good behavior stars

Step-by-step explanation:

Let

x ----> the number of weeks

y ----> the number of good behavior stars

we know that

Alice

$y=x+8$ ----> equation A

Mack

$y=2x+2$ ----> equation B

To find out in how many weeks will they have the same number of good behavior stars, equate equation A and equation B

$2x+2=x+8$

Solve for x

$2x-x=8-2$

$x=6\ weeks$

Verify

For x=6 weeks

Alice

$y=(6)+8=14\ stars$

Mack

$y=2(6)+2=14\ stars$

therefore

In 14 weeks will they have the same number of good behavior stars

72% can also be written as 0.72, so take 0.72 x 45 = 32.4

Subtract 32.4 from 45 45 - 32.4 = 12.6 You need 12.6 renewals in 5 days.

What you have to do to find the median of the data is first put that data into order numerically. You can go largest to smallest or smallest to largest, it doesn't matter. 

22, 24, 28, 28, 30, 31, 31, 32, 32, 35, 36, 37, 38, 41, 42, 42, 44, 44, 45, 46, 46, 47, 47, 49, 50

Once you put them into order, you count towards the middle. You have 25 data points, so the middle, which will be your median number, will be 13 points in.

The median is 38
