Answer:
C
Step-by-step explanation:
The volume of a cone is given by 
The volume of a cylinder is given by 
<em>Where h is the height and r is the radius</em>
The first figure is a cone with height 6 and radius 5, we can put it into the formula and find the volume:

The second figure is a cylinder with height 50 and radius 1, we can put it into the formula and find the volume:

We can see that they are equal. So answer choice C is right.

You need to distribute the 3, so your answer would be 6b-3
Answer:
a) 0.7225
b) 0.5220
c) 0.478
It is not unusual.
Step-by-step explanation:
Probability grocery bags are plastic = 85% = 0.85
a) If two grocery bags are chosen at random, the probability that both grocery bags are plastic would be:
b) If four bags are chosen at random, the probability that all are plastic:
Probability all four bags chosen randomly are plastic bags is 0.5220
c) The probability that at least one of four randomly selected grocery bags is paper:
Let's first check for the probability of getting a paper bag.
P(paper bag) = 1 - 0.85 = 0.15
Probability of getting a paper bag is 0.15
Probability that at least one of four randomly selected grocery bags is paper would be:

Since the probability that at least one bag is paper, 0.478 is greater than 0.05, it is not unusual.
