How can you calculate value of cos20?
the simple way to culculate this value is to ist consider the basic trignometric ratio near to 20. Than we come that 30 is near to it and cos30 is equal to 0.866 now for 1 dgree rise or fall the costheta decrese by the factor 0.0009 since cos20 is 10 dgree far frm thrty so multiply 0.0009 by 10 and subtract from 0.866. U wil get answer of cos20
What are the changes that a sample size can change to standard deviation?
Consider thatxd= x- Arithmetic meand211-1.5 = -0.50.2522-1.5 = 0.50.25=0.5Arithmetic mean = (1+2)/2 =1.5Standard deviation=ie .5= 0.70now Considerxd= x- Arithmetic meand211-2=-1122-2=0033-2=11Arithmetic mean= (1+2+3)/3 = 2 =2Standard deviation= = (2/2) = 1So the Standard deviation can increasenow Considerxd= x- Arithmetic meand211-1.25=-0.250.062522-1.25=0.750.562511-1.25=-0.250.062511-1.25=-0.250.0625Arithmetic mean= (1+2+1+1)/4= 1.25 = .75Standard deviation= = (0.75/4) = 0.4330So the Standard deviation can decreaseStandard deviation can either decrese or increase or remains the same
