Answer: 0.6065
Step-by-step explanation:
Given : The machine's output is normally distributed with
Let x be the random variable that represents the output of machine .
z-score : 
For x= 21 ounces
For x= 28 ounces
Using the standard normal distribution table , we have
The p-value : 
Hence, the probability of filling a cup between 21 and 28 ounces= 0.6065
Answer:
yes
Step-by-step explanation:
4.2*3 is 12.6 when you divide 12.6 by 0.7 you get 18.
Let's make an equation where x is the number of gallons and y will be the overall price.
2.5x=y; since it is $2.52 PER gallon, you need to multiply the amount of gallons by the cost. In this case, it is 4.
2.5(4)=10
So, the price of 4 gallons is $10.
Step-by-step explanation:
Divided by zero is undefined. Hence B is the answer.
