Answer: The correct answer is 10 piranhas.
Step-by-step explanation:
To calculate the total Volume of a cylinder we have to use the following formula:
Volume = Area * Height
Area = π * r² , where r= radius
The diameter is always the twice the radius so the diameter is 4 feet in this case and the radius is 2 feet so the area is
Area= 3.1416 * (2*2)
Area = 3.1416 * 4
Area = 12.5664 square feet
Volume = 12.5664 (area) * 1.25 (height).
Volume = 15.708 cubic feet
Each piranha needs 1.5 cubic feet so we have to divide the total Volume by the volume that each piranha needs
15.708/ 1.5 = 10.472 or ten pirahnas because we can't put a fraction of a piranha in the tank.

Step-by-step explanation:
GIVEN DATA :
Test statistic = 4.99
significance level = 1% = 0.01
k ( number of groups ) = 3
will we use the chi-squared test to determine the degree of freedom
which is : k-1 = 3 - 1 = 2
looking at the chi-square table to determine the critical value of the test
at significance level = 0.01 and degree of freedom = 2 the critical value = 9.21
Comparing the test value ( 4.99 ) and the critical value ( 9.21 ) it can seen that the test value < critical value which is a condition for not rejecting null hypothesis of the test.
therefore we won't reject the null hypothesis
Answer:
11 cans
Step-by-step explanation:
1 hr = 60 min
33 hrs = ? min
Setup proportion and solve for x:
Do butterfly method and get x = 1980 minutes
Then take the 1980 divide it by 180 to find the number of cans.
Answer:
The answer is 600
Step-by-step explanation:
Because 50×12=600
