3 kg because one year is approximately 3 half-lives of W-181. The amount remaining would be 1/23<span> or 1/8. That is 3 kg of W-181.</span>
For the manager's store
Population size: 15
Arithmetic mean (μ): 37.6
Standard deviation (σ): 11,056
For the competitor's store
Population size: 15
Arithmetic mean (μ): 48,533
Standard deviation (σ): 28,356
For the manager's store the average is a better representation of the data since it does not have Outlier points in the box diagram. Also the median is close to the average.
For the competition store the average of the data collected is not as good representation of the data since they are dispersed from the mean with a standard deviation of 28.35. It also presents Outliers points in the box diagram, such as 112 which is very far from the average
Answer:
67.3%
Step-by-step explanation:
Calculate profit = selling price - cost price
cost price = 50 × $28 = $1400
38 × $49 = $1862
12 × $40 = $480
selling price = $1862 + $480 = $2342
Profit = $2342 - $1400 = $942
% profit = 
× 100%
= 
× 100% ≈ 67.3% ( to 1 dec. place )
