In any distribution is the sum of the squared deviations from the mean always equal to zero?
No. It cannot be. Remember that when you square a negative number it becomes a positive number. Thus all squared deviations are positive and their sum must be positive.
An odd number squared would always equal an odd number and an even number squared would always equal an even
No. They are equal only if the distribution is symmetrical.
No, because the hyponenuse is always longer than the legs, so they are not equal, a squared + b squared = c squared
it equals positive one. one squared is always one. if they're both negative, negative times negative is always positive.
-It is symmetrical (mean = median) -It is bell shaped (empirical rule applies) -The interquartile range equals 1.33 standard deviations -The range is appr. equal to 6 stand. dev.
Sin squared is equal to 1 - cos squared.
yes......... a metre square is always equal to square metred
It is equal to zero in ALL distributions.
3 squared is equal to 9
It states that in a right triangle, the longest side of the triangle squared is equal to the sum of the remaining two sides squared. The formula used for this is a²+b²=c². C is always equal to the longest side of the triangle, while A and B are equal to the two shorter sides of the triangle.
Under the normal curve if the mean of the distribution of raw scores is equal to 68 then its equivalent z score is equal to?
The z score for the mean is always 0.
A negative times a negative is always positive. To see why this is, see the link below.
144 squared x 36 squared is equal to 26,873,856.
289 squared times 289 squared is equal to 6,975,757,441.
13 squared x 4 squared is equal to 2,704.
36 squared times 24 squared is equal to 746,496.
12 squared plus 18 squared is equal to 468.
3 squared plus 2 squared is equal to 13.
25 squared plus 49 squared is equal to 3,026.
6 squared plus 9 squared is equal to 117.
For different sets of data, the mean would be the summation of all observations, which are normally subdivided by the observation numbers. The mean value would frequently be quoted with standard deviations: mean would describe data central locations then standard deviations illustrate the spread. Substitute dispersion measures include mean variations that are always equal to average absolute deviations from the mean values. It is minimally responsive to the outliers. Hope this helps.
No, it equals positive 9. Any negative number squared will always give a positive result; the square root of a negative number is always imaginary (a mathematical term, referring to 'i'). So, (-3)2 = 9 and -32 = -9.
(a+b)(a+b) Also equal to a2+2ab+b2
177 mm squared is equal to 350 MCM AWG.
It's equal to positive b squared, or (b x b) .
1 squared plus 8 squared or 4 squared plus 7 squared
a squared plus b squared is equal to c squared
-2 squared will be 4. Remember that two negative numbers multiplied will always result in a positive answer. Therefore, any number squared will be positive (except 0 where the result will be 0).
No. Two negatives multiplied together or a negative number that is squared always equals a positive number. So it would equal 144 not -144
4 m squared 1cm sqaured is equal to 0.0001m squared
Equal distribution of wealth is associated with the ideas of Communism and Socialism.
(1 metre) squared = (1000 mm) squared = 1000000 mm squared.
a2 + a2 = 2a2
2.7 squared = 7.29
9a squared = 81a^2
NO!! Cosine squared theta = 1 - Sine squared theta, not plus.
The exponential distribution and the Poisson distribution.
No. it's not a prime number when x = 40, 41, 81,82 ...
1 squared radical 40 is equal to 1 squared radical (4 x 10), and this become 2 squared radical 10. By adding 2 squared radical10 with 3 squared radical 10 we get 5 squared radical 10.
3 squared is 9, 5 squared is 25. So the product is 225.
No, three squared is nine. 3(squared sign) =3x3 =9
one squared equals one.
lokiya said: 9 squared is equal to 81
when 144 is squared it is the same as 12
Because in a right angle triangle the square of its hypotenuse is always equal to the sum of each side squared.
They are all equal . . . they are the same. (In an asymmetric distribution they are not equal.)
The sum of proportions computed from a frequency distribution must equal
When a number is squared, it means that it is that number is multiplied by itself. So in this case it would be 9x9 which is equal to 81.
If x is equal to 5, then x squared plus 25 is equal to 50.
The hypotenuse of a right angle triangle when squared is equal to the base squared plus the height squared and the formula is usually given as:- a2+b2 = c2 whereas a and b are the base and height respectively and c being the hypotenuse which is the largest side
