Te difference of 2 standard deviation of a population n1 & n2 is given by the formula:
sigma (difference)=√(sigma1/n1 + sigma2/n2), Plug:
sigma(d)= √(49/100 + 36/50)
Sigma(d=difference) =1.1
Mono means one..but monomial can also a negative. Mono meaning one means there is a single variable.
It would actually be -14 because 5+4-2=7 and if you multiply 7 by -2 you get -14
