By what number should-37/75 be divided to get 74/100​

Answer»

Answer:

To find the standard deviation of a SET of numbers, first find the mean (AVERAGE) of the set of numbers:

10+15+19+35+27+446=25

Second, for each number in the set, subtract the mean and SQUARE the result:

(10−25)2+(15−25)2+(19−25)2+(35−25)2+(27−25)2+(44−25)2=826  

Then add all of the SQUARES together and find the mean (average) of the squares, like this:  

8266=137.67  

Finally, take the square ROOT of the second mean:  

137.7−−−−√=11.7.
