In the figure below, if a = 4 and b = 20, then c is approximately 19.45. true or false
asambeis [7]
False. To find C, we can use the equation:

a^2 + b^2 = c^2

4^2 + 20^2 = c^2

c^2 = 416

c = approximately 20.40

Suppose that a random variable X is continuously uniform between the values of 3 and 8. Find the variance of the distribution of
Korolek [52]

The formula of the variance of the distribution of sample mean of a random variable X, which it will denoted by V(\bar{X}), is

\frac{\sigma^2_X}{n}\ ,\\

where n is the size of the sample.

Since X is continuously uniform between 3 and 8, you have

\sigma^2_X = \frac{(8-3)^2}{12} = \frac{25}{12} \ .

Therefore,  the variance wanted is  V(\bar{X} ) = \frac{25}{26\cdot12}\approx0.0801
