The amount of soda a dispensing machine pours into a 12-ounce can of soda follows a normal distribution with a mean of 12.45 ounces and a standard deviation of 0.30 ounce. Each can holds a maximum of 12.75 ounces of soda. Every can that has more than 12.75 ounces of soda poured into it causes a spill and the can must go through a special cleaning process before it can be sold. What is the probability that a randomly selected can will need to go through this process?
A. 0.3413
B. 0.1587
C. 0.6587
D. 0.8413
Normal distribution: P(X < A) = P(Z < (A - mean)/standard deviation)
Mean = 12.45 ounces
Standard deviation = 0.30 ounce
P(a randomly selected can will need to go through this process) = P(X > 12.75)
= 1 - P(X < 12.75)
= 1 - P(Z < (12.75 - 12.45)/0.30)
= 1 - P(Z < 1)
= 1 - 0.8413
= 0.1587

The amount of soda dispensing machine pours into a can of soda is normally distributed with a mean of 12 ounces and a standard deviation of 0.2 ounces. Find the probability that a can contains less than 11.75 ounces of soda
The amount of cereal that can be poured into a small bowl varies with a mean of 1.5 ounces and a standard deviation of 0.3 ounce. A large bowl holds a mean of 2.5 ounces with a standard deviation of 0.4 ounce. A student opens a new box of cereal and pours one large and one small bowl. Suppose that the amount of cereal the manufacturer puts in the boxes is a random variable with a mean of 16.2 ounces...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
