Answer:
Step-by-step explanation:
Given that X is a normal random variable with parameters µ = 10 and σ 2 = 36,
X is N(10, 6)
Or z = 
is N(0,1)
a) P(X > 5),
=
(b) P(4 < X < 16),
=
(c) P(X < 8),
=
(d) P(X < 20),
=
(e) P(X > 16).
=P(Z>-0.6667)
= 0.2524
C)5.40
The answer is $5.40 because 5 x 8=40 and the sales tax is 8% so you just add 2 decimal places so 5.00 + .40 =5.40.
P.S. You put the answer in your question.
