At UF, there are always a few days between the end of classes and the beginning of final exams. These days are meant as a study
Natalija [7]

Answer:

This sample is not representative of all UF students, since those who are not local are not considered.

Step-by-step explanation:

This is a common statistics practice, when we want to study something from a population, we find a sample of this population.

However, the sample has to be representative

For example:

I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So i ask, lets say, 1000 randomly selected Buffalo residents wheter they are Buffalo Bills fans, and expand this to the entire population of New York State residents. This is not representative of all New York State residents, just Buffalo residents.

In this problem, we have that:

They conduct a phone survey (with local numbers selected at random from the student directory) calling people during "dead week". Will this sample be representative of all UF students?

They only call those students with local numbers.

However, in an university, it is expected that there will be a good percentage of non local students.

So this sample is not representative of all UF students, since those who are not local are not considered.

It is recommended that adults consume at least 1,000 mg of calcium every day. One ounce of whole milk contains about 25 mg of ca
ohaa [14]

Answer:

20 ounces of milk and 3 ounces of cheddar cheese

30 ounces of milk and 4 ounces of cheddar cheese

40 ounces of milk and 5 ounces of cheddar cheese

Step-by-step explanation:

Consider the inequality 25x+200y\geq 1000

Here, x denotes ounces of whole milk and y denotes ounces of cheddar cheese.

To write: three different amounts of milk and cheese that a person could consume to meet the recommendation

Solution:

Take x=20,y=3

25(20)+200(3)\geq 1000\\500+600\geq 1000\\1100\geq 1000

So, x=20,y=3 satisfy the inequality 25x+200y\geq 1000

Take x=30,y=4

25(30)+200(4)\geq 1000\\750+800\geq 1000\\1550\geq 1000

So, x=30,y=4 satisfy the inequality 25x+200y\geq 1000

Take x=40,y=5

25(40)+200(5)\geq 1000\\1000+1000\geq 1000\\2000\geq 1000

So, x=40,y=5 satisfy the inequality 25x+200y\geq 1000

Therefore,

three different amounts of milk and cheese that a person could consume to meet the recommendation are as follows:

20 ounces of milk and 3 ounces of cheddar cheese

30 ounces of milk and 4 ounces of cheddar cheese

40 ounces of milk and 5 ounces of cheddar cheese
