<h2>Answer:</h2>

The answers are as follows:

Biases samples are those where some members of the population are not included in the survey. These samples produce biases results.

The statements that could lead to biased results are :

1. Giving a standardized test to a class of at-risk students : Only at risk students are biased samples here.

2. Asking players on a school football team how much they study : The school football team will have a very few students as compared to the whole school.

3. Asking Republicans for their opinion about a Democrat-sponsored bill : The republicans here are a part of all the population that contains democrats, liberals and republicans. So sample is biased.

Using complete sentences, explain how to find the quotient of 8 2/3 ÷ 1 3/5. Make sure to include the quotient in your answer.​
White raven [17]

Answer:

6 over 1/24

Step-by-step explanation:

You can find the quotient of 9 2/3 divided by 1 3/5 by first making the two terms into improper fractions.

To make the improper fractions, you can turn 9 2/3 into 29/3 by multiiplying 9 by the denominator (bottom number in fractions)  and adding that to the numerator of 2 which gives 29.

1 3/5 can turn into 8/5.

Then you can divide using a simple trick of first organizing the data.

Currentlly it should be

29/3 divided by 8/5

Then you can flip the second fraction over.

29/3 divided by 5/8

Then you change the sign into multiplication.

29/3 times 5/8

Then you multiply like normal.

29 times 5 over 3 times 8

145 over 24

You can simplify now

6 over 1/24

Hope this helps!
