A lab at the DeBakey Institute orders 150 rats a week for each of the 52 weeks in the year for experiments that the lab conducts
FromTheMoon [43]

Answer:

a. The expected or average costs for all weekly rat purchases is $20.00

Step-by-step explanation:

a. A mean value of $20.00 means that over a period of 52 weeks, the company can expect to spend $20.00 per week on rat purchases.

b. This is incorrect since individual values don't interfere in the mean. For instance, if half the weeks had a cost of $19.00 and the other half had a cost of $21.00, the mean cost would still be $20.00 even though no particular week had a $20.00 cost

c. Incorrect. The median is the central value in a distribution; the median and the mean are not necessarily the same.

d. Incorrect, same as item b.

How do you solve this?? Please help!
Aleks04 [339]

f = (f1 f2) / (f1 + f2)

f(f1 + f2) =  f1 f2

f f 1 + f  f 2 = f1 f 2

f1 f2 - f f2 = f f1

f2 (f1 - f)  = f f1

f2 = (f f1) / (f1 - f) <==== solution
