Answer:
34% of lightbulb replacement requests numbering between 47 and 52
Step-by-step explanation:
The Empirical 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 = 52
Standard deviation = 5
Between 47 and 52:
52 is the mean and 47 is one standard deviation below the mean.
By the Empirical Rule, 68% of the measures are within 1 standard deviation of the mean.
Since the normal distribution is symmetric, of those, 34% are within 1 standard deviation below the mean and the mean(47 and 52) and 34% are within the mean and one standard deviation above the mean(52 and 57).
So
34% of lightbulb replacement requests numbering between 47 and 52
D. Computer game designer.
They'e use geometry mostly in graphics.
"Isometric Graphic Design can be used to create an object that appears to be 3D, but is not. Isometric projection is the process of tilting a certain axis to change the angle at which an object is viewed."
Answer:
About 706.5 or 707
Explanation:
3.14 • 5² (5² is also 25) = 78.5
78.5 • 9 = 706.5 or 707
