The lifetime, in years, of some electronic component is a continuous random variable with the density f(x) =   k x4 for x ≥ 1 0 for x < 1. Find k, the cumulative distribution function, and the probability for the lifetime to exceed 2 years.

1) is right

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.
