Answer:
75 miles
Step-by-step explanation:
If the bird flies for 90 minutes at 50 mph (miles per hour), we need to calculate how many hours 90 minutes is.
One hour is 60 minutes. Our equation will be: 90/60 = 1.5
This mean the bird flies 1.5 hours at 50 mph. To find the distance, we multiply 1.5 by 50.
1.5 × 50 = 75
The bird has flown 75 miles.

Standard deviation is used to determine how the values in a group differs from the mean of the values in the group.
In order to determine the standard deviation, take the following steps:
• Determine the mean of the observation: 14
Determine the difference between each value and the mean and then square the result: (12 - 14)² + (14 - 14)² + (9 - 14)² + (21 - 14)² = 78
Determine the mean of the sum of the squared differences and then find the square root of the mean: √78/(n - 1) = 5.1

To find the median, put all numbers into ascending order and work into the middle by crossing off numbers at each end. If there are a lot of items of data, add 1 to the number of items of data and then divide by 2 to find which item of data will be the median.
