If the diagram is this

Then it would go like this
|dw:1392274742487:dw|
|dw:1392274778511:dw|
|dw:1392274826374:dw|
|dw:1392274862633:dw|
The answer would be 72
area
51: 147.5
52: 108
53: 78.80
Sorry Im having trouble finding the perimeter but Hope i helped with the area =)
1st Step - Find the mean (average):
245 + 300 + 325 + 465 + 100 = 1435
1435/5 = 287 ( mean)
2nd step find the sun of the sqaure the difference between the gievn data and the mean
287 - 245 = 42^2 = 1,764
300 - 387 = 13^2 = 169
325-287 = 38^2 = 1,444
465 - 287 = 178^2 = 31,684
287 - 100 = 187^2 = 34,969
1,764 +169 + 1,444 + 31,684 + 34,969 = 70,030
Now divide that by the number of samples minus 1 ( 5-1=4)
70,030 / 4 = 17,507.5
The variance = 17, 507.5
Well, I don't know. Let's see . . . . .
First draw: One 'M' available out of 11 letters. Probability of picking it = 1/11.
2nd draw: Four 'I's available out of 10 letters. Probability of picking one = 4/10.
3rd draw: Four 'S's available out of 9 letters. Probability of picking one = 4/9.
4th draw: Three 'S's available out of 8 letters. Probability of picking one = 3/8.
5th draw: Three 'I's available out of 7 letters. Probability of picking one = 3/7.
6th draw: Two 'S's available out of 6 letters. Probability of picking one = 2/6.
7th draw: One 'S' available out of 5 letters. Probability of picking it = 1/5.
8th draw: Two 'I's available out of 4 letters. Probability of picking it = 2/4.
9th draw: Two 'P's available out of 3 letters. Probability of picking one = 2/3.
10th draw: One 'P' available out of 2 letters. Probability of picking it = 1/2.
11th draw: One letter left. It is an 'I'. Probability of picking it = 1 .
Probability of all of those draws in order =
(1/11) x (4/10) x (4/9) x (3/8) x (3/7) x (2/6) x (1/5) x (2/4) x (2/3) x (1/2) x (1) =
1,152 / 39,916,800 =
1 / 34,650 =
0.00002886 =
<em> 0.002886 percent</em> (rounded)
Not a good bet. (But better than the lottery.)

Step-by-step explanation:
Fill in the numbers: It's the 100s chart cut into pieces. You are looking for numbers that are 1 less, 1 more, 10 less or 10 more than a number.
