Given that
the weight of football players is distributed with a mean of 200 pounds and a standard deviation of 25 pounds.
And we need to find What is the minimum weight of the middle 95% of the players?
Explanation -
Using the Empirical Rule, 95% of the distribution will fall within 2 times of the standard deviation from the mean.
Two standard deviations = 2 x 25 pounds = 50 pounds
So the minimum weight = 200 pounds - 50 pounds = 150 pounds
Hence the final answer is 150 pounds.
Answer:
Ed used 39/60 of one hour to complete his tasks.
Step-by-step explanation:
Find the least common denominator (LCD), which would be 20
Then, find how to get from 5 to 20 and 4 to 20.
Use division.
20/5 = 4, 20/4 = 5
After this, multiply the numerator to the according number.
2*4 = 8 = 8/20
1*5 = 5 = 5/20
Make the denominator 60 to represent 60 minutes in one hour
5/20*3/3 = 15/60
8/20*3/3 = 24/60
Add the two results.
15/60 + 24/60 = 39/60
