Answer:
The percentage of people taking the test who score between 391 and 767 is 95%.
Step-by-step explanation:
The Empirical Rule(68-95-99.7 Rule) states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 579
Standard deviation = 94
391 = 579 - 2*94
So 391 is two standard deviations below the mean.
767 = 579 + 2*94
So 767 is two standard deviations above the mean.
By the Empirical Rule:
The percentage of people taking the test who score between 391 and 767 is 95%.

Answer:
1600cm³
Step-by-step explanation:
Volume of a cylinder = πr²h
area of a circle = πr²
area of base circle = 200cm²
h = 8
200 * 8
= 1600cm³
(Since there are no options to chose from, I guess I'll just do my own answer and you'll have to pick the closest one to this one. Or, you could comment the options and I could help you there too.)
Answer:
Yes, the outcomes are likely because there is an equal number of each type of marble.
Step-by-step explanation:
Since there is an equal number of each color of marble, the outcomes of the event are equally likely. If there were more of one marble, it would be unlikely.
For example, if there were 7 blue marbles, 7 red marbles, but there were 8 yellow marbles, then the event would be unequally likely because there were more of the yellow marbles. So the answer is yes, the outcomes are equally likely.
