The volume of water in the vase is the difference of volume of cylinder and that of the marbles.
Vcylinder = πr²h = π(6 in)²(12 in) = 432π in³
Vmarbles = 9(4πr³/3) = 9(4π(3 in)³/3) = 324 π in³
The difference of the volumes is 108π in³.
Answer:

Given
Toppings: Pico de gallo, Onions and Steak
Required
The probability of getting Onions and Steak
The probability is calculated using:
--- because the events are independent

Answer: if you simplify this it becomes 30=28 but this is a false statement so you would say 30≠28
Step-by-step explanation:
≠ means not equal
Answer:
Step-by-step explanation:
Since population std deviation is not known, we use t critical value for testing of hypothesis.
a) 90% conf level when n =28
df = 27, t critical = 1.706
b) 95% 28
df =27 and t critical = 2.052
c) 90% and 15
df =14 and t critical = 1.761
d) 95% and n =15
df =14: t critical = 2.145
