C. The way the sample was chosen may overrepresent or underrepresent students taking certain language classes.
The samples he chose may not be a representative sample because the number of students per foreign language class may not be the same. Since classes have different numbers of students, one may have a very large number of students while another may have only a few. Taking equal number of students per class is not a representative sample because it doesn't represent the students correctly.
The common ratio is 8
example:
-3 x 8 = -18
-18 x 8= -108
so on so on
Answer:
QUIT CHEATING JK THE ANSWER IS y = 2/3x + 3
Step-by-step explanation:
= 2/3(-3) + b Solve for b
1= -6/3 + b
1 = -2 + b
+2 +2
b = 3
The equation will be y = 2/3x + 3
You have to find out what 15% of $78 dollars is. If you have to do this in your head and not on a calculator you can find 10%, then cut that number in 1/2 and add it to the answer. So 10% of $78 is 7.8 so $7.80. You can divide 7.80 by 2 and get 3.9 and add that to 7.8 which is 11.70. So 15% of $78 is $11.70.
