Answer:
400,000 gallon's of fuel oil
200,000 gallon's of gasoline
Explanation:
Constraint 1: you must produce at least 2 gallons of fuel oil for every gallon of gasoline
So for every three gallons you must have 2 fuel oil and one gasoline.
Thus 600,000/3 = 200,000
200,000 × 2 = 400,000 fuel oil 200,000 × 1 = 200,000 gasoline
Constraint 2: is that at least 150,000 gallons of fuel oil must be produced. 400,000 is greater than 150,000
Answer:
This is a stratified random sample because a separate random sample is selected from each class
Explanation:
Stratified random sampling is an appropriate method when the population consists of mixed characteristics and you would like to ensure that every characteristic is proportionally represented in the sample. In this example, the population is the students from Central High School and the mixed characteristics are the different classes such as Freshman students, Sophomore students, Juniors and Seniors.
After the population is divided into subgroups based on characteristics, from the overall proportion of the population, you calculate how many people should be sampled in each subgroup. Random or systematic sampling can then be used to select a sample from each subgroup.
Assuming that the amount of money he buys the car for + gas, maintenance, etc. costs outweighs the cost saved by biking or public transportation (if he's OK with doing those two), he should probably consider walking, biking, or using public transportation for those few years
Answer:
Effect on income= -$2,100
Explanation:
Giving the following information:
Contribution margin $ 98
Increase in variable cost= $5
Increase in sales= 300 units
<u>To determine the effect on income, we need to use the following formula:</u>
Effect on income= increase in contribution margin for new sales - increase in variable costs
Effect on income= 300*93 - 6,000*5
Effect on income= -$2,100
