A tap root is just one big root like a carrot or a tap root goes straight down and A adventitious root may come out from under ground part of the plant except the radicle as in a number of monocots
First,find the mean of the set. Then,find the differences between every item and the mean Square them Find the mean of the squared differences The square root of that is the standard deviation
Standard deviation is equal to the square root of the variance. To arrive at this work out the mean, then subtract the mean and square the result of each number. Then work out the mean of those squared differences and take the square root of that.
a is a real number since we use just letters to represent real numbers. if a > 0, then its square root is also a real number, so it has two square roots, one positive and one negative. Be careful when you use the radical sign, because it is looking only for the principal square root of a, which is the positive one. if a < 0, then its square root is an imaginary number.
