Answer:
25.14% probability that his score is at least 582.5.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
If 1 of the men is randomly selected, find the probability that his score is at least 582.5.
This is 1 subtracted by the pvalue of Z when X = 582.5. So
has a pvalue of 0.7486
1 - 0.7486 = 0.2514
25.14% probability that his score is at least 582.5.

The volume of a cylinder refers to the number of cubic units that will exactly fill a cylinder. The volume of a cylinder can be found or calculate by using the formula V=πr^2(h), where r represents the radius of the figure.
In this exercise is given that the radius of a cylinder is 3 millimeters and the height is 7 millimeters, and it is asked to find its volume. In order to find the volume of the given cylinder, you should substitute the values for the radius and height into the previous mention formula.
V=πr^2(h)
V=(3.14)(3mm)^2(7mm)
V=(3.14)(9mm^2)(7mm)
V=(3.14)(63mm^3)
V=197.82 mm^3
The volume of the cylinder is 197.82 cubic millimeters.
I’m pretty sure it’s 2911/9700 if not than it’s... 2426/9700+1/70+1/28 not EXACTLY sure but if I were you I’d go with the first one, or not listen to me at all... that’s perfectly fine. You’re welcome!
