Answer: a) 
Step-by-step explanation:
Given : For safety reasons, four different alarm systems were installed in the vault containing the safety deposit boxes at a Beverly Hills bank.
Each of the four systems detects theft with a probability of .99 independently of the others .
Probability for independent events 
occurs together = 
.
Then, the probability that when a theft occurs, all four systems will detect it
= (0.99) x (0.99) x (0.99) x (0.99)
Hence, the probability that when a theft occurs, all four systems will detect it is .
Hence, the correct answer is a) .

Step-by-step explanation:
<span>There are 8 pints in 1 gallon, so 3 pints is 3/8 of a gallon </span>
The function and the first value stated for x are confusing.
Doing some research, I found that the problem is to evaluate the function
for x = - 1 and x 2.
The solution is:
1) For x = - 1
2) For x = 2
Step-by-step explanation:
Surface Area of the Cylinder
= 2πr² + 2πrh
r = 4 in
h = 16 in
Surface Area :
= 2πr² + 2πrh
= 2π (4)² + 2π (4) (16)
