The mean and standard deviation of the number of questions that each student gets correct are 4 and 1.789 respectively (
Answer:
61.7% of container A is empty after the pumping is complete.
Step-by-step explanation:
The volume of a cylinder is calculated by the formula B×h, where B is the area of the base, or radius²×π.
The volume of cylinder A is 9²×π×10=810π.
The volume of cylinder B is 5²×π×20=500π.
The percent that will be used to fill container B is the complete volume of B out of A: ≈.61728395 which is 61.7% rounded to the nearest tenth.
X=.8(50)
x=40
Therefore 40 is 80% of 50.
Hope this helps!
(Also the formula I used is: part = percent * whole)

Hi,
For this question, we are given the following system of equations:
2x - y = 3
x + y = 3
Let's make the first equation in the form of y = mx + b as shown below:
y = 2x - 3
x + y = 3
Now, substitute the first equation into the second to get:
x + 2x - 3 = 3
Combine similar terms to get:
3x = 6
x = 2
We now know that x = 2 and can plug this value into one of the given equations to get:
2 + y = 3
y = 1
FINAL ANSWER: x = 2 ; y = 1
I hope that helps you out!
