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

7х + 2y = -1<br> 3х — 4y = 19
Deffense [45]

Answer:

x = 1, y = -4

Step-by-step explanation:

7х + 2y = -1  ------ eq1

3х — 4y = 19 ------ eq2

multiply eq1 by 2

2 x (7х + 2y = -1)

14x + 4y = -2 -----eq3

by elimination, add equation 2 and 3

14x + 3x = 19-2

17x = 17  (divide both sides by 17)

x = 1  (answer)

substitute into eq1

7(1) + 2y = -1  (subtract 7 from both sides)

2y = -1 -7

2y = -8 (divide both sides by 2)

y = -8/2 = -4 (answer)

Please help!! <br> Solving Surface area problems
nadezda [96]

Answer:

84.8 sq in

Step-by-step explanation:

The area of the top and bottom are each 1/2(3.7 x 4) = 7.4, so they total 14.8

2 of the sides are 5 x 5 = 25, so they total 50

1 side is 5 x 4 = 20

14.8 + 50 + 20 = 84.8 sq in
