P(1.15 < z < 2.37) = P(z < 2.37) - P(z < 1.15) = .9911 - .8749 = .1162
Look up 2.37 and 1.15 in table (attached)
2.37 ----> 0.9911
1.15 ----> 0.8749

D
Step-by-step explanation:
A recursive formula lets us calculate a term in the sequence by multiplying the previous term by the common ratio r
for the sequence
- 3, 9 , - 27 , 81....
the common ratio r is
r = 9 ÷ - 3 = - 27 ÷ 9 = 81 ÷ - 27 = - 3
Then the recursive formula is
f(n) = - 3 f(n - 1) if n > 1
f(1) = - 3
option D
