A random variable X follows the uniform distribution with a lower limit of 670 and an upper limit of 750. a. Calculate the mean

weqwewe [10]

Answer:

a) $E(X) = \frac{a+b}{2}=\frac{670+750}{2}= 710$

The variance is given by:

$Var(X) =\frac{(b-a)^2}{12}= \frac{(750-670)^2}{12}= 5333.3333$

And the deviation is just the square root of the variance and we got:

$Sd(X) = \sqrt{5333.333}= 23.09$

b) $P(X$

And for this case we can use the cumulative distribution given by:

$F(X) = \frac{x-a}{b-a} , a \leq x \leq b$

And replacing we got:

$P(X$

Step-by-step explanation:

For this case we assume that X is our random variable and we know that the distribution for X is given by:

$X \sim Unif(a=670, b = 750)$

Part a

For this case the expected value is given by:

$E(X) = \frac{a+b}{2}=\frac{670+750}{2}= 710$

The variance is given by:

$Var(X) =\frac{(b-a)^2}{12}= \frac{(750-670)^2}{12}= 5333.3333$

And the deviation is just the square root of the variance and we got:

$Sd(X) = \sqrt{5333.333}= 23.09$

Part b

For this case we want to find this probability:

$P(X$

And for this case we can use the cumulative distribution given by:

$F(X) = \frac{x-a}{b-a} , a \leq x \leq b$

And replacing we got:

$P(X$

Rudiy27

<span>I would say this answer should be correct since what we need is a straight line that crosses the two streets to be able to determine ie measure the two either acute or obtuse angles between the two lines to see if corresponding angles are the same. If they are then that shows that the two streets are parallel. d. Park, bus stop, and his friend's house</span>
