Determine the standard deviation (SD)
The standard deviation of a binomial distribution is calculated as thus:
Substitute values for n and p
Convert to decimals
--- <em>approximated</em>
<em>Hence, the calculated standard deviation is approximately 8.4932</em>
The distance between the boats after 1 minute would be 130 ft.
Given that a lake is 200ft wide, and two boats start to move towards one another from opposite shores, and in one minute, the first boat goes 40 ft and the second one goes 30 ft, to determine what would be the distance between the boats after 1 minute the following calculation must be performed:
- Total width - boat distance 1 - boat distance 2 = Distance after 1 minute
- 200 - 40 - 30 = X
- 130 = X
Therefore, the distance between the boats after 1 minute would be 130 ft.
