Answer:
The probability is 0.003
Step-by-step explanation:
We know that the average
is:

The standard deviation
is:

The Z-score is:

We seek to find

For P(x>800) The Z-score is:



The score of Z = 3 means that 800 is 3 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the conficion of 3 deviations from the mean has percentage of 0.15%
So

For P(x<200) The Z-score is:



The score of Z = -3 means that 200 is 3 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the conficion of 3 deviations from the mean has percentage of 0.15%
So

Therefore



Answer: all points
that satisfy
Step-by-step explanation:
The slope of the line is

So, substituting into point-slope form, the equation is

Therefore, all points
that satisfy
will lie on the same line.
The volume of number three is 63.7
Answer:
i think it's <C and <R since they're 90 degree angles, though they are small
The answer would be 5.291 10 to the power of 12
