=============================================================

Explanation:

The data set is

{0,0,0,1,2,2,2,2,2,3,4}

The median is the middle-most value. To find it, cross off the outer pair of values until you narrow in on the median of 2. It should be the second copy of it. Check out the diagram below to see what I mean.

Then break up the set into

L = {0,0,0,1,2}

U = {2,2,2,3,4}

Each subset mentioned has 5 items. The diagram below also shows how set L and set U are formed. L is the stuff below the median, aka lower set. Set U is the upper set, which is stuff above the median.

The median of set L is 0, while the median of set U is 2

So we have the first and third quartiles of Q1 = 0 and Q3 = 2

The difference of these is the IQR

IQR = Q3 - Q1 = 2 - 0 = 2

For some reason, the number 2 shows up a lot in this problem.

It's pretty easy, take the example of this fraction... [tex]\frac{2}{4}[/tex]

What you do in here is that you note down the factors of 2 and 4 over here.

Factors of 2 and 4:

2 = 1, 2

4 = 1, 2, 4

Now, you see that the GREATEST Common Factor (GCF) over here is 2.

Now that we see the GCF of 2 and 4 is 2, what you do next is, you have to divide 2 by 2 AND 4. When you do this, you will get your results. 2 = 1 and 4 = 2, now put this in the fraction form again, meaning switch 2 with 1, and 4 with 2 in the fractions... [tex]\frac{1}{2}[/tex]

So your simplified fraction is [tex]\frac{1}2}[/tex]!

Answer:

A fraction is in simplest form when the top and bottom cannot be any smaller, while still being whole numbers.

You can simplify a fraction by dividing the top and bottom by the greatest number that will divide both numbers exactly. They must stay whole numbers.

Step-by-step explanation:

Finding the Surface Area :

Step-by-step explanation:

just take a deep breath, shake your limbs, and then focus on it again.

the surface consists of 5 areas :

front and back triangles (2)

left rectangle

right rectangle

floor rectangle

the area of a rectangle is simple :

length × width

the area of a triangle is

baseline × height / 2

each of the front and back triangles has an area of

5 × 4 / 2 = 5×2 = 10 cm²

both of them have then 10×2 = 20 cm²

the left rectangle is

9×6 = 54 cm²

the right rectangle is

9×5 = 45 cm²

the floor rectangle is also

9×5 = 45 cm²

so, the total surface area is

20 + 54 + 45 + 45 = 164 cm²

Answer:

Step-by-step explanation:

10 - 8.20 = 1.8

1.8 / 3 = 0.6

Hope this helps you :D

Answer: $0.60

Step-by-step explanation:

Facts

got 3 lbs of oranges

paid with $10, got 8.20 in change.

Step 1: Find how much the 3lbs of oranges actually cost (actual total)

10-8.20= 1.8

Step 2: Find the unit rate (cost per lb)

Cost per lb. Divide the cost by the number of pounds, as shown:

1.8/3= 0.6

Step 3: Checks

[hypothetically], each pound costs 0.60.

Buying 3 pounds of oranges, multiply 0.6x3= 1.8.

Now, you pay with $10.

To find how much change you get, subtract 10-1.8= 8.20

These computations are correct, and the resulting facts match those given in the question. This is how I double check the answer is accurate.

Hence, each pound costs $0.60, or 60 cents.

Step-by-step explanation:

The population of 150,000 decreases each year by 150

  Since the population is decreasing it would be -150 iguana's

         [tex]\frac{-150 iguanas }{1 year}[/tex]

Answer: A

Step-by-step explanation:

facts

there are 150,000 iguanas. each year, we lose 150.

The rate of change is a fixed amount of something increasing or decreasing in a certain amount of time. Since the population loses 150 iguanas each year, the rate of change, or unit rate, is -150 (if it decreases, its negative).

Answer:

Naja earns 64$ per 8 hours of work

Step-by-step explanation:

2 steps:

Step 1

Divide 5 by 40 to find how much dollars per hour

[tex]\frac{40}{5} =8[/tex]

8, so that means that Naja earns $8 per hour

Step 2

Multiply 8 by 8 to get final answer

[tex]8*8=64[/tex]

$64, so that means that Naja earns 64$ per 8 hours of work

Answer:

$64 for 8 hrs.

Step-by-step explanation:

There are 2 ways you could do this. The easy way is the first one.

1. Divide 40 by 5 and you get 8. 2. After you get that answer, then you have to multiply 8x8=64. So she gets $64 per hour.

Then there is the harder one. This is if they say to show your work.

1. Start by putting it in this format:

5 -- 40

6 -- 48

7 -- 56

8 -- 64

So you basically just add 8 each time to get 64.
