Answer:
9,000,000,000 gallons of water.
Step-by-step explanation:
We have been given that a website recommends that you should have 3 gallons of water for every inch of goldfish in your tank. We are asked to find the gallons of water needed for one billion goldfish that are each 3 inches.
First of all, we will find gallons of water needed for each fish.


Now, we will multiply number of gallons of water required for 1 fish by 1 billion to find required gallons of water.


Therefore, you need 9,000,000,000 gallons of water for 1 billion fish.
Answer:
153.586 close to 154 students
Step-by-step explanation:
mean=61
standard deviation =10
sample 450 students , x between 61 and 71
(x-mean)/deviation for score 61 and 71
61-61/10=0
71-61/10=1
the z-scores is between 0 and 1 ( use calculator)
the percentage is 0.3413 close to 34%
number of students that score between 61 and 71=
450*0.3413= 153.586 close to 154 students
