<h2>Answer with Step-by-step explanation:</h2>

set of ordered pair is a function if no input value has two output values

i.e. if ordered pair is of form (x,y) then no value of x will have more than one values of y

{(-2,1),(-1,3),(2,1),(-2,2)}

-2 has two output values

so, it is not a function

{(-1,4),(1,4),(2,4),(-2,4)}

It is a function

{(-1,3),(-1,4),(-1,5),(-1,6)}

-1 has m ore than one output values

so, it is not a function

{(2,2),(3,3),(4,4),(2,1)}

2 has two output values

so, it is not a function

Question:

Chucky grabbed 11 items in the grocery store that each had a different price and had a mean cost of about $4.44. On his way to the register, he gave in to an impulse to add a 12th item: an entire wheel of cheese that cost $39.99.

How will adding the wheel of cheese affect the mean and median?

Answer:

There will be a big difference in the mean when the new item is added

Step-by-step explanation:

Given

Items = 11

Mean = \$4.44

Before we solve further, we need to first calculate the total amount of the 11 items.

Mean = \frac{Total}{Items}

Make Total the Subject of formula

Total = Mean * Items

Total = \$4.44 * 11

Total = \$48.84

When the 12th item of $39.99 is added, the new mean becomes.

New\ Mean = \frac{Total + \$39.99}{11 + 1}

New\ Mean = \frac{\$48.84 + \$39.99}{11 + 1}

New\ Mean = \frac{\$88.83}{12}

New\ Mean = \$7.4025

By comparing this the old mean, we can see a huge increment between $4.44 and $7.4025

This means that there will be a big difference in the mean when the new item is added.

For the Median:

The old mean shows that the prices of the 11 items is within a small range from $4.44.

So, when the new item is added the median will only change a little bit.

In other words, the median value will only change a little bit.

Feliz [49]

Answer:

27

Step-by-step explanation:

25,16,21,30

Put the numbers in order from smallest to largest

16,21,25,30

The median is the middle and the median is 25  so the new number must be 25 or larger

The only number on the the list that is 25 or largest is 27
