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

Answer:
The length side of the square is 
Step-by-step explanation:
<u><em>The question in English is</em></u>
Find the measure of the side of a square whose diagonal is 14 cmd
Let
d ----> the diagonal of a square in cm
b ---> the length side of a square in cm
we know that
Applying the Pythagorean Theorem
see the attached figure to better understand the problem
we have
substitute the given value
solve for b
take square root both sides
simplify
35 x .95 = 33.25. 33.25 is how much off it was, so now you subtract that number by 35 and get 1.75. Melissa bought the item for $1.75
