First we have to find the mean (average)
mean = (564 + 1000 + 848 + 1495 + 1348) / 5 = 5255 / 5 = 1051
now we subtract the mean from every data point, then square it
564 - 1051 = -487......-487^2 = 237169
1000 - 1051 = -51......-51^2 = 2601
848 - 1051 = -203......-203^2 = 41209
1495 - 1051 = 444......444^2 = 197136
1348 - 1051 = 297......297^2 = 88209
now find the mean of the results.....but know when ur dealing with a sample instead of the whole population, u divide by 1 number less...so instead of dividing by 5, u divide by 4.
(237169 + 2601 + 41209 + 197136 + 88209) / 4 = 566324 / 4 =
141581.....this is called ur variance
now take the square root of the variance and u have ur standard deviation
sqrt (141581) = 376.272 rounds to 376.27 <==
16/10
All you have to do to get another way to write a fraction is double the original fraction.
For example...
1/2 = 2/4 = 4/8 = 8/16...
All these are half, 8/16 is the same as 1/2.
Hope this helped. Have a great night!
Simplifying makes a algebric expression easily understandable and solvable.
Volume is measured of the objects which are three-dimensional .. And square is just a shape , hence it doesn't have any formula for volume .
.
If you were tryna ask about cube , the formula for cube is s^3
Where s is the side of the cube
