Given the table below, evaluate the following:

x -3 -2 -1 0 1 2 3 4 5
f(x) 10 20 30 40 50 60 70 80 90
g(x) -1 -2 -3 -4 -5 -6 -7 -8 -9

a. (3f+2g)(1)

b. (f o )

Barbara deposited $300 in the bank. if the bank pays her simple interest at the rate of 4 percent per year, how much money will she have in her account at the end of 9 months?

Factor the following expression. 27y3 – 343 a. (3y + 7)(9y2 + 2ly + 49) b. (3y – 7)(9y2 + 2ly + 49) c. (3y – 7)(932 – 217 + 49) d. (3y + 7)(92 – 2ly + 49)

1. if events a and b are non-overlapping events, how do you find the probability that one or the other occurs? 2. what does it mean if p(a or b) equals 1?
