Alab at the debakey institute orders 150 rats a week for each of the 52 weeks in the year for experiments that the lab conducts. suppose the mean cost of rats used in lab experiments turned out to be $20.00 per week. interpret this value. a. the median cost for the distribution of rat costs is $20.00 b. the expected or average costs for all weekly rat purchases is $20.00 c. most of the weeks resulted in rat costs of $20.00 d. the rat cost that occurs more often than any other is $20.00 g

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

Step-by-step explanation:

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.

Suppose the mean cost of rats used in lab experiments turned out to be $20.00 per week.

Means means average. We can say that the average cost is $20 per week, that will give $20 as an average for the year.

Hence, the answer is : The expected or average costs for all weekly rat purchases is $20.00

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
