Answer:
Step-by-step explanation:
Let X be the no of adults whose feelings the state of morals is poor.
X has two outcomes and each trial is independent of the other
X is Bin with p = probability for success in each trial =40%=0.40
n=no of adults surveyed = 55
a) The probability that exactly 21 of those surveyed feel the state of morals is poor is

(b) The probability that no more than 22 of those surveyed feel that state of morals is poor is
=
(c) The probability that more than22 of those surveyed feel the state of morals is poor is

(d) The probability that 15 or 16 believe the state of morals is poor is
=
Answer:
12 years
Step-by-step explanation:
From the formula;
A = P(1 + r)^n
A = Amount = $2733.19
P = Principal = $2150
r = rate = 2%
n = time in years = ???
2733.19 = 2150(1 + 0.02)^n
2733.19/2150 = (1 + 0.02)^n
1.27 = (1.02)^n
Taking logarithm of both sides
log 1.27 = n log 1.02
n= log 1.27/log 1.02
n= 0.1038/0.0086
n = 12 years
