both had differences in geometry
Answer:
C. The principal randomly selects homeroom classes and surveys each student in the chosen classes.
Step-by-step explanation:
Middle school is 6-8th. Surveying only the eighth-grade students won't give a representative sample of the whole school only the eighth-graders. Option A is incorrect.
Surveying only the students in detention represents a very small amount of students compared to the school, therefore it is not a representative sample. Option B is incorrect.
Yet again, the students in the math club is a small amount of students compared to the school. It does not represent the entire, or majority of the population. Option D is incorrect.
Picking students from homeroom classes and surveying each will give a wider variation of opinions from each grade and therefore a representative sample. Option C is the correct answer.
The easiest way to calculate this, since you don't need to know what the discount is, if the decrease is 4% you still have 96%.
Multiply 29,000 x .96= $27,840.
If you do it the other way, .04 x 29000= 1160. Then subtract 29000-1160=27850.
Answer:
-3-i is the correct answer.
Step-by-step explanation:
Answer:
m = y-b/x
Step-by-step explanation:
y = mx + b
0 = - y + mx + b
-mx = -y + b
m = -y + b / -x
m = y - b / x
