Brand X: median value is 13. Look carefully at the diagram so that you can spot and understand where that value comes from.
Brand Y; median value is 16.
We can conclude that the life of Brand Y batteries is always greater than that for Brand X, and that the medians differ by 3 hours.
Answer:
the 3rd
Step-by-step explanation:
because n^2+3n+2n simplifies to n(n+5), which is not equivalent to 6n
Answer:
Each factory should supply 100 units
x = 100 units
y = 100 units
Step-by-step explanation:
Since the total production must be 200 units, then x + y = 200.
The cost function can be rewritten as a function of 'x' as follows:

The value of 'x' for which the derivate of the cost function is zero, is the production level that minimizes cost:

In order to minimize production costs, each factory should supply 100 units
The fraction would be 7/9.
