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 $V(\bar{X} ) = \frac{25}{26\cdot12}\approx0.0801$

Answer:In order to specify a line completely, all you need is

Step-by-step explanation:

co-ordinates of any one of the points it passes through (say, (x1,y1) ), and

its inclination (slope = m).

Its equation, by virtue of the definition of the slope then becomes,

y−y1x−x1=m

Whence, for our case,

y−2x+6=−12

which simplifies to

x+2y+2=0

Which ordered pair would form a proportional relationship with the point graphed below?

kvasek [131]

Answer:

$(x,y) = (-30,10)$

Step-by-step explanation:

Given

$(x,y) = (60,-20)$

Required:

Determine a pair with a proportional relationship

A proportional relationship is:

$k = \frac{y}{x}$

Where k is the constant of proportionality.

$(x,y) = (60,-20)$

So, we have:

$k = \frac{-20}{60}$

$k = -\frac{1}{3}$

This means that for a pair to have a proportional relation, k must be -1/3.

This is true for (c).

Where:

$(x,y) = (-30,10)$

So, we have:

$k = \frac{10}{-30}$

$k = -\frac{1}{3}$
