The tests done to determine if someone is hiv positive are called enzyme immunoassay or eia tests. the test screens a blood sample for the presence of antibodies to hiv. like most tests, this test is not perfect. the table below shows the approximate probabilities of positive and negative eia tests when the blood does and does not actually contain the hiv antibodies. long range studies have shown that only 2% of the population actually has the hiv antibodies. test result positive negative antibodies present 0.9985 0.0015 antibodies not present 0.006 0.994 a) explain in context all four values in the table. that is, what does each of them actually mean? construct a tree diagram to answer the following questions. the first two choices of the tree should be whether or not the antibodies are present. the second choice should be the test result. (what is the probability split for the first choice? ) b) what is the probability that a person without hiv will have a test come out positive (this is called a false-positive)? c) what is the probability that a person with hiv will have a test come out negative (this is called a false negative)? d) what is the probability that a person with hiv will have a test come out positive?

An art teacher made a copy of a small painting. to make the painting easier to see the teacher enlarged the area of the painting by 49%. let y respresent the area of the original painting. the expression below is one way to resperesnt the area of the new painting. find two equivalent expressions that would give the area of the new painting y+0.49y
