Answer:
Mean = 84.9
Median = 89
Mode = 89
Step-by-step explanation:
89 , 76 , 89 , 89 , 100 , 71 , 80
First, we need to arrange in either ascending or descending order. In this case, let us arrange in ascending order:
71, 76, 80, 89, 89, 89, 100
1. The mean is simply the sum of all the variables divided by the number of variables
Mean = (71+76+80+89+89+89+100)/7
Mean = 594/7
Mean = 84.9
2. Median is the middle term of the distribution
Median = 89
3. Mode is the variable with the highest frequency i.e the variable that appears the most
Mode = 89
This is a translation and it is most easily done with the vertex from of the equation. change vertex to (-1,6): y=a(x+1)+6
Answer: C
Step-by-step explanation:
If a line is perpen to another line, then the other line has the opposite reciprocal of the slope.
y=-(1/4)x+2
slope of the other equation is +4
oly answer with positive slope is C
