The 4 is equal to 20 which the second fraction in 15/20 so 4x5= 20 which would mean 15 divided by 5= ? 3x5= 15.

Answer:

(-2,3)

Step-by-step explanation:

Multiply -3x+4y=18 with 2:

-6x+8y=36

Add -6x+8x=36 and 6x+2y=-6

10y=30

y=3

So y=3 we can replace y with 3 on any of these two equations:

6x+6=-6

Move the 6 to the other side:

6x=-12

x=-2

So the solution is

(-2,3)

Hope this helps

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:

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

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

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

$s=\sqrt{8.3333}$

$s=2.8867$
