What is the relationship between the variance and standard deviation? variance is the positive square root of the standard devia
lana [24]

Variance of a continuous random variable X is defined as

\int\limits_D {(x-\mu)^2f(x)} \, dx

Standard deviation is defined as

\sigma =  \sqrt{Var(X)}

Hence standard deviation is the positive square root of variance.

I dont understand this help me :( What is the equation of a line with a slope of ​3​ and a point (3, 1) on the line?
spayn [35]

\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{1})~\hspace{10em} slope = m\implies 3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-1=3(x-3) \\\\\\ y-1=3x-9\implies y=3x-8

Write a formula for the sequence of cube numbers: 1, 8, 27, 64, ….
Marianna [84]

Answer: n^3, where n = 1,2,3,4,.....

Step-by-step explanation:

The given sequence : 1, 8, 27, 64, ….

We observe that the terms are perfect cubes of consecutive integers (starting from 1) .

Terms can be written as:

First term =  a_1=1=1^3

Second term=a_2=8=2^3

Third term = a_3=27=3^3

Fourth term =a_4=64=4^3

Thus , for any nth term ,the formula for the sequence is : n^3, where n = 1,2,3,4,.....
