A firm's average revenue function AR=−18−7,5Q+Q2.AR=−18−7,5Q+Q2.
Determine the number of units to be produced and sold to maximise revenue.
Edwill just purchased a new home costing R1107900,00 by paying R120000,00 cash on the purchase date, and agreeing to make payments at the end of the following eight years for the remainder owed; the first payment is due one year after the purchase date. The interest rate is 7,4 % per annum,compounded yearly. Considering the amortisation schedule, the percentage rounded to two decimal places, of the total payments made the first two years that will go forward repayment of interest, is
1/2 y² sin(x²)

f(c )= 9.8 * 68.1/c [1- e(-0.146813c) ] – 40. Search your answer between c values 12 to 16.Assume minimum error to be considered as 0.001.
In a study of inter spousal aggression and its possible effect on child behavior, the Behavior
Problem Checklist (BPC) scores were recorded for 47 children and whose parents were classified as
aggressive. The sample mean and standard deviation were 7.92 and 3.45, respectively. For a
sample of 38 children whose parents were classified as non-aggressive, the mean and standard
deviation of the BPC scores were 5.80 and 2.87, respectively. Do these observations substantiate
the conjecture that the children of aggressive families have lower mean BPC than those of non-
aggressive families? Use a significance level of 0.05.

A recreational motor manufactures golf carts and snow mobiles at its three plants.
Plant A produces 40 golf carts and 35 snow mobiles daily. Plant B produces 65 golf carts
daily but no snow mobiles and plant C produces 53 snow mobiles daily but no golf carts.
The cost of operating plants A, B and C are respectively Birr 12.6 million, 11.4 million
and 10.92 million per day. How many days (including Sundays and holidays) should each
plant operate during September to fulfill a production schedule of 1500 golf carts and
1100 snow mobiles at minimum cost? Assume that labour contracts require that once a
plant is opened, workers must be paid for entire day.
