Computer Help Hot Line receives, on average, 14 calls per hour asking for assistance. What is the probability that the company will receive 3 calls in a 12 minute period?

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.
