Good evening

Answer:

<h2>75</h2><h2 />

Step-by-step

let c be the total number of cartoons

Cost of purchase = 50c

total sale price = 100(c-15)

profit = total sale price - cost of purchase    

        = 100(c-15) - 50c = 2250 cents

Then (100c-50c) - 1500 = 2250

then 50c = 3750

Then c = 3750/50 = 75

Answer:

A. principal interviewed the 25 students who scored highest on a reading test.

D. For a report on the exercise habits of adults, Sergio talked to 30 adults at a local fitness center.

E. Josh asked the first 25 people he met at the dog park if they preferred dogs or cats.

Step-by-step explanation:

Biased means if the selection of every unit does not have an equal chance of being selected in a sample.

The sample is said to be good if choosing the unit is unbiased. The sample is said to be unbiased if the selection of each unit is independent.

Option A is an example of data selected in a biased way because principal chose only those student who scored the highest marks on reading test.

Options B and C are unbiased as here a selection of each number and name of the student has an equal chance of being selected.

Option D is biased because Sergio talked adults at a local fitness center where people go for maintaining their health. So, there is a chance of the selection of fitted adults more than unfitted adults.

Option E is biased because Josh met people at the dog park where dog lovers are more than a cat lover.
