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:

$P(24< X$

AC and DG are parallel. Find the value of x, show CLEARLY how you got your answers with reasons

valentinak56 [21]

Answer:

x = 79°

Step-by-step explanation:

∠ABE = ∠BEF = 41° [Alternate angle ]

Now sum of angles of a triangle = 180°

Therefore,

∠EBF + ∠BEF + ∠BFE = 180°

60° + 41° + x = 180°

x = 180° - 60° - 41°

x = 79°

The volume of a cylinder with height and radius can be found using the formula

Illusion [34]

Answer:

7 feet

Step-by-step explanation:

Volume of a cyclinder = πr^2h

Volume of a cyclinder = 1952

π = 3.14

r = ?

h = 2r

Volume of a cyclinder = πr^2h

1952 = 3.14 * r^2 * 2r

1952 = 3.14 * 2r^3

1952 = 6.28r^3

Divide both sides by 6.28

r^3 = 1952 / 6.28

= 310.83

r^3 = 310.83

Find the cube root of both sides

r = 6.77 feet

Approximately 7 feet
