Suppose that 24% of the students in the first group answered yes and that 73% of the students in the second group answered yes.
Lera25 [3.4K]

Answer:

Price Discrimination OR Law of Demand; according to the complete question.

Step-by-step explanation:

24% of the students in the first group answered yes.

73% of the students in the second group answered yes.

More students in the second group were willing to pay $75 for the pair of jeans BECAUSE they were told that the normal price was much higher.

From this information, I guess that the first group was told (by the jeans vendor probably) that the $75 was higher than the normal price of the jeans. This will be the reason why a lesser percentage of students in Group A are willing to purchase the pair of jeans.

This is an example of PRICE DISCRIMINATION effect on decision making. Price discrimination is used in product marketing.

The same pair of jeans in Situation A cost higher than the normal price while in Situation B it cost lower than the normal price. Even though the figure given is static at $75 in both cases, the data that follows in the question tells it as 2 different prices; one favourable to the buyers and another not so favourable to the buyers.

The LAW OF DEMAND also applies here. The higher the price, the lesser the quantity demanded (by a group of students) and the lower the price, the higher the quantity demanded.

Help with 9 and 10 and show your work plz and thanks
worty [1.4K]
For number 9 you have to convert from fraction to precent, the way i do this is by multiplying my denominator by a variable to get 100.
in this instance my denominator is 5 so 5x=100 in this case we are multiplying by 20. so 1(20)=20. it is important to recognize that 1/5 is equal to 20/100. now that we have an equivilent fraction we can use the numerator to be our precent. so the answer is A.20%

for number 10 we use the same idea. we know that 20 percent of people are for the visiting team so the rest of the pie chart would mean 80 percent of people were for the home team. We take the total number of people  which is 64,000 and multiply our 80 percent, so we move the decimal
 64,000(.80)=51200
so the answer for 10 is D.51200

The probability of not choosing a black shirt is...? please explain!
AleksAgata [21]

Answer:

80% or 8/10.

Step-by-step explanation:

Assuming the shirts in the bottom right are the "black" shirts, there is ten total shirts (1 red, 4 blue, 2 green, 1 white,  2 black.) Out of the ten shirts, 8 are not black. This means that there is an 80% chance that you will select a shirt that is NOT black.
