A random variable x is uniformly distributed over the interval (-4, 6). Find the standard deviation of x. (Note: Uniform distrib
Pachacha [2.7K]

Answer:

The standard deviation of x is 2.8867

Step-by-step explanation:

The standard deviation of variable x that follows a uniform distribution is calculated as:

s = \sqrt{\frac{(b-a)^{2} }{12} }

Where (a,b) is the interval where x is defined.

So, replacing a by -4 and b by 6, the standard deviation is:

s = \sqrt{\frac{(6-(-4))^{2} }{12} }

s = \sqrt{\frac{(10)^{2} }{12} }

s=\sqrt{\frac{100}{12} }

s=\sqrt{8.3333}

s=2.8867

What is the surface area of the square pyramid?
yawa3891 [41]
The answer is 240 because 11 x 8 is 88 but you divide by 2 since it's a triangle so you get 44 and since there's 4 triangles you do 44 x 4 and get 176 then 8 x 8 is 64 plus 176 is 240
