Find the limit by finding the lowest common denominator. For every there is such that implies. Add or subtract the numerators and then cancel terms.
Lim x 2 x 2 4 x 12 x 2 2 x 0 0 lim x 2 x 2 4 x 12 x 2 2 x 0 0.
So we cant just plug in x 2 x 2 to evaluate the limit. Find the LCD of the fractions on the top. 5 5 10. The standard deviation of the sample is equal to the standard deviation of the population divided by the square root of the sample size.
