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.

A firm manufactures a commodity at two different factories. The total cost of manufacturing depends on the quantities x and y su
SVETLANKA909090 [29]

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:

y=200-x\\C=f(x,y) =2x^2+xy+2y^2+500\\C= f(x) = 2x^2+x(200-x)+2(200-x)^2+500\\C= f(x) = x^2+200x+500+2(x^2-400x+40,000)\\C= f(x) = 3x^2-600x+80,500

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

C= f(x) = 3x^2-600x+80,500\\C'= f'(x)=0 = 6x-600\\x=100\ units\\y = 200 -x = 100\ units

In order to minimize production costs, each factory should supply 100 units
