Answer:
5000 because you round up
Answer: the third choice.
Step-by-step explanation:
Answer:
By the Empirical Rule, approximately 68% of the bulbs have lifetimes that lie within 1 standard deviation to either side of the mean.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
What percentage of the bulbs have lifetimes that lie within 1 standard deviation to either side of the mean?
By the Empirical Rule, approximately 68% of the bulbs have lifetimes that lie within 1 standard deviation to either side of the mean.
First find how many numbers are between the two by subtracting
4400 - 3400 = 1000
now to find half way between the two divide 1000 by 2
1000/2 = 500
so the number between the two is 500 +3400 and 4400-500
which is 3900
Answer:
-.125
Step-by-step explanation:
5/8 + 3/4 solve
2/3 - 5/6 solve
then subtract your numbers
