Suppose the time to failure in hours of certain electronic components subjected to continuous vibrations is found to be a weibull random variable with κ=1.1,and λ=1/2.

(a) how long should we expect this component to last when we install a new one in a particular system?

(b) given that one of these components has already lived to the expected lifetime, what is the probability it will last another 50%of the expected lifetime?

horizontal translation of 2 units in the positive x direction

vertical translation of 3 units in the positive y direction

16.9 times 2.85

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

c.
