Walter wants to learn more about the preferred salad ingredients of students in his
school. He surveys all students in his math class and finds that 4 prefer tomatoes,
14 prefer carrots, and 9 prefer cucumbers. What is the population and sample? Is
the sample a representative sample? Explain.

For example , If we want to calculate the average income of American data scientist , all American data scientists will be determine the population in this case,

Here, Walter surveys all students in his math class and finds that 4 prefer tomatoes, 14 prefer carrots, and 9 prefer cucumbers.

Population = All students in his School

Sample = Students in his class.

No, the sample is not a representative sample, it is the convenience sample.

It can be possible that his class has influence of him or students of other classes may like exactly different ingredients for salad like sprouts, fruit etc.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

answer
