Charles wants to find out if the students in foreign language classes spend more time in class speaking in english or in the foreign language they are studying. charles first gets class lists of all students taking foreign language classes. he then chooses 10 students from each different language class to survey. which best explains why the sample he chose may not be a representative sample?
a. the sample size is not large enough to represent the population.
b. the sample was not chosen at random.
c. the way the sample was chosen may overrepresent or underrepresent students taking certain language classes.
d. the way the sample was chosen does not sample students from each different language class.

Option A

Step-by-step explanation:

Given that Charles wants to find out if the students in foreign language classes spend more time in class speaking in English or in the foreign language they are studying. Charles first gets class lists of all students taking foreign language classes. He then chooses 10 students from each different language class to survey.

Option A is right since sample size of 10 is not a sufficient size

Option B is wrong because all languages were considered while drawing the sample

Option C is wrong because each student from each language taken

Option D is also wrong

Hence correct answer is option A

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
