How do you evaluate an arithmetic series if the sigma notation is not given?
Pattern recognition
What does sigma means in mathematics?
sigma is the short for sums for example, lets say you want to add 1+2+3+4+5+6.................+99+100 it's a problem writing every single term, right? so if the sum it's a pattern like the example above, you can write it in sigma notation search it up on the internet and find some simple examples because i am not the best explainer in the world =) **Sigma is also used in statistics to mean "standard deviation."
What is the for this problemgive the exponential notation and standard notation for 2x2x2x2x2?
The exponential notation and standard notation for 2x2x2x2x2 is:2532
In a normal distribution with mu equals 25 and sigma equals 3m what number corresponds to z equals -3?
z = (x-mu)/sigma So x = sigma*z + mu = 3m*(-3) + 25 = -9m + 25
How do you compute one sigma deviation?
Let x denote the values of the variable in question. Suppose there are n observations. Let Sx = the sum of all the values. then the mean of x, Mx = Sx/n Let Sxx = the sum of all the squares of the values. The Vx (= the variance of x) is Sxx - (Mx)^2 and sigma(x) = sqrt(Vx). Therefore one sigma deviation, relative to the mean, = Mx - sigma(x), Mx + sigma(x).
