Answer: D) At the next school assembly, choose one student from each of 20 randomly selected rows.
Step-by-step explanation:
A wouldnt be correct because it is all students from the spots program
B isnt correct because it is 10 girls and 10 boys from the girls' and boys' soccer teams
C wouldnt be correct because it would be the first 20 students she sees once she leaves statistics class
D is the only unbiased, completely random selection choice.
So a number (x because unknown) divided by 40 (x divided into 40 parts or x/40) has a quotient of 6 with a remainder of 16 (answer=6 with 16 remainder)
remember that remainder is not involved in division, just leftover
x/40=6+16 remainder
to get rid of the fraction, multiply the whole equation by 40 and add the remainder (since it wasn't involved in division)
x=240+16
x=256

number=256
