Answer: The probability that the project will be completed in 33 days or less is equal to<u> </u><u>0.73</u> .
Step-by-step explanation:
We assume that this is a normally distribution.
Given : The critical path length is 30 days .
i.e. Population mean = 
Variance : 
Then, standard deviation : 
Z-score : 
The value of z corresponding to 33 = 
Now, the p-value = 
Hence, the probability that the project will be completed in 33 days or less is equal to 0.73.
The equation that represents the graph of the ellipse is x² / 4 + y² / 100 = 1. (Correct choice: D)
<h3>What is the equation of the ellipse represented in the graph?</h3>
Herein we have a representation of an ellipse in the image attached aside, ellipses are characterized by the following <em>standard</em> formula:
(x - h)² / a² + (y - k)² / b² = 1 (1)
Where:
- (h, k) - Coordinates of the center
- a, b - Lengths of the semiaxes
Please notice that ellipse will be vertical if b > a, otherwise it will be horizontal. The graph exhibits a <em>vertical</em> ellipse centered at the origin and therefore we conclude that (h, k) = (0, 0) and b > a (b = 10, a = 2). Finally, the equation that represents the graph of the ellipse is x² / 4 + y² / 100 = 1. (Correct choice: D)
