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? the sample size is not large enough to represent the population. the sample was not chosen at random. the way the sample was chosen may overrepresent or underrepresent students taking certain language classes. the way the sample was chosen does not sample students from each different language class.

The way the sample was chosen does not sample students from each different language class.

I think this one but don’t hold me to it! Hope this helps!

The way the sample was chosen may over represent or under represent students taking certain language classes.

Step-by-step explanation:

Given is - Charles first gets class lists of all students taking foreign language classes. He then chooses 10 students from each different language class to survey.

In such selection, it is possible that students in each foreign language class may not be the same. One class can have a very large number of students as compared to others. Charles is selecting equal number of students per class and this is not a representative sample.

So, the option that is correct here is - The way the sample was chosen may over represent or under represent students taking certain language classes.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
