5. Given the relative-frequency table below, find the expected value of x. x P(X = x) 3 .02 5 .39 7 .12 9 .47

if you mean

then it's c. 8, -7/3

but if you mean

then it is

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

what is the answer to this
