Suppose the sample space for a continuous random variable is 0 to 100. If the area under the density curve for the variable from 0 to 80 is 0.85, what is
the area under the density curve from 80 to 100?
O A. 0.15
B. 0.20
C. 0.80
D. 0.85

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
