First, you have to arrange them in proper numerical order (least to greatest).

84, 88,90,92,96

Next, find the mean by adding them all up and dividing them by 5.

84 + 88 + 90 + 92 + 96 = 450

450 divide by 5 equals 90.

Now, that we have our mean, we have to subtract it from each of the numbers in the data set. Remember this is absolute so there is no negatives.

84 - 90 = 6

88 - 90 = 2

90 - 90 = 0

92 - 90 =2

96 - 90 = 6

Next, line them up again.

2,2,6,6

Find the mean of them:

2 + 2 + 6 + 6 = 16

16 divided by 4 is 4.

Therefore, our answer would be the MAD is 4.0

What is 5,000 x 60 x 2

goldenfox [79]

Do it as simply as possible. 5000 × 2 = 10000. 60 × 10000 = 600000. Because multiplying by a factor of 10 is the easiest possible, always try to get a factor of 10 every time.

How is six and five hundredths written in expanded notation and numerals

Usimov [2.4K]

Answer:

In Expanded notation it is $6\times 1 + 5\times \frac{1}{100}$

In numerals it is 6.05

Step-by-step explanation:

Expanded notation

Expanded notation is a helpful way to rewrite numbers in order to show the place value of each digit.

Normal number of we have

.........,Hundred, Tens ,Unit

eg. 1.) 514

5 = hundred place

1 = tens place

4= unit place

Now for decimal numbers

tenths,hundredths,thousandths........

eg. 1.) 0.25

0 = unit place

2 = tenths place $\frac{1}{10}$

5 = hundredths place $\frac{1}{100}$

We will have example in numerals and it expanded notation.

6.05 ( six and five hundredths)

Expanded form

$6\times 1 + 5\times \frac{1}{100}$

Here,

6 is in Unit place

0 is in Tenths place

5 is in Hundredths place
