The thickness of a protective coating applied to a conductor designed to work in corrosive conditions follows a uniform distribu

pochemuha

Answer:

$P(24< X$

And replacing we got:

$P(24< X$

Step-by-step explanation:

We can define the random variable X as the thickness of a protective coating applied to a conductor designed to work in corrosive conditions. And the distribution for X is given by:

$X \sim Unif (a = 20, b=40)$

And we want to find this probability:

$P(24< X$

And in order to find this probability we can use the cumulative distribution function given by:

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

And if we use this formula for the probability desired we have:

$P(24< X$

And replacing we got:

$P(24< X$

If h(x) = 5 x and k(x)=1/x, which expression is equivalent to (koh)(x)?

Lyrx [107]

May be there is an operator missing in the first function, h(x). I will solve this in two ways, 1) as if the h(x) = 5x and 2) as if h(x) = 5 + x

1) If h(x) = 5x and k(x) = 1/x

Then (k o h) (x) = k ( h(x) ) = k(5x) = 1/(5x)

2) If h(x) = 5 + x and k (x) = 1/x

Then (k o h)(x) =k ( h(x) ) = k (5+x) = 1 / [5 + x]
