Question 92738This question is from textbook
: 5) the function P = 13 + 45lnx represents the percentage of inbound e-mail in the U.S. that is considered spam, where x is the number of years after 2000.
Carry all calculations to six decimals on each intermediate step when necessary.
a) Use this model to approximate the percentage of spam in the year 2003.
ALL I CAN SAY IS HUH?
b) Use this model to approximate the year that the percent of spam will reach 95% provided that law enforcement regarding spammers does not change.
