What is the mean absolute deviation of the data set?<br><br> 2, 2, 5, 6, 8, 4, 8, 5
DedPeter [7]

ANSWER

The mean absolute deviation is 1.75

EXPLANATION

The given date set is 2, 2, 5, 6, 8, 4, 8, 5

The mean is

\bar X =  \frac{2 + 2 + 5 + 6 + 8 + 4 + 8 + 6}{8}  = 5

The mean absolute value deviation is given by:

=\frac{ \sum |x -\bar X| }{n}

=  \frac{ | 2 - 5|  +  |2 - 5|+  |5- 5|+  |6 - 5|+  |8 - 5| +  |4 - 5|+  |8- 5|+  |5 - 5| }{8}

=  \frac{ 3  +  3+ 0+  1+  3 + 1+3+  0}{8}

=  \frac{14}{8}

= 1.75

352 divided by 2 in long division please show work
baherus [9]

Step 1:

Start by setting it up with the divisor 2 on the left side and the dividend 352 on the right side like this:

2 ⟌ 3 5 2

Step 2:

The divisor (2) goes into the first digit of the dividend (3), 1 time(s). Therefore, put 1 on top:

1

2 ⟌ 3 5 2

Step 3:

Multiply the divisor by the result in the previous step (2 x 1 = 2) and write that answer below the dividend.

1

2 ⟌ 3 5 2

2

Step 4:

Subtract the result in the previous step from the first digit of the dividend (3 - 2 = 1) and write the answer below.

1

2 ⟌ 3 5 2

- 2

1

Step 5:

Move down the 2nd digit of the dividend (5) like this:

1

2 ⟌ 3 5 2

- 2

1 5

Step 6:

The divisor (2) goes into the bottom number (15), 7 time(s). Therefore, put 7 on top:

1 7

2 ⟌ 3 5 2

- 2

1 5

Step 7:

Multiply the divisor by the result in the previous step (2 x 7 = 14) and write that answer at the bottom:

1 7

2 ⟌ 3 5 2

- 2

1 5

1 4

Step 8:

Subtract the result in the previous step from the number written above it. (15 - 14 = 1) and write the answer at the bottom.

1 7

2 ⟌ 3 5 2

- 2

1 5

- 1 4

1

Step 9:

Move down the last digit of the dividend (2) like this:

1 7

2 ⟌ 3 5 2

- 2

1 5

- 1 4

1 2

Step 10:

The divisor (2) goes into the bottom number (12), 6 time(s). Therefore put 6 on top:

1 7 6

2 ⟌ 3 5 2

- 2

1 5

- 1 4

1 2

Step 11:

Multiply the divisor by the result in the previous step (2 x 6 = 12) and write the answer at the bottom:

1 7 6

2 ⟌ 3 5 2

- 2

1 5

- 1 4

1 2

1 2

Step 12:

Subtract the result in the previous step from the number written above it. (12 - 12 = 0) and write the answer at the bottom.

1 7 6

2 ⟌ 3 5 2

- 2

1 5

- 1 4

1 2

- 1 2

0

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 352 divided by 2 calculated using Long Division is:

Can someone help me please!!!
Andre45 [30]

Answer: 3

<u>Explanation:</u>

Since we want the least number of integers, divide by the largest integer (9).

2018 ÷ 9 = 224 remainder 2

So, N = 2999...999 <em>(there are 224 of the 9's) </em>

Thus, N + 1 = 2999...999 + 1 <em>(there are 224 of the 9's) </em>

<em>                   </em>= 3000...000     <em>(there are 224 of the 0's) </em>

The sum of the digits is: 3 + 0 + ... + 0  <em>(there are 224 of the 0's) </em>

                                      = 3
