X=y/20-1/4 solve for y and show properties

y = 20x + 5

Step-by-step explanation:

X =  Y/20 - 1/4

In this type of expression you will first of all find the LCM of the right hand side

x = y - 5/ 20

the next thing to do is to cross multiply

we have,

20x = y - 5

dont forget we are to solve for y in the equation, so to solve for y we have

20x + 5 = y

therefore y will be expressed in terms of x as written below

y = 20x + 5

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
