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
What?? what is the original price?
Answer:
-3
Step-by-step explanation:
You group the like terms together
6a+2a=24-8
8a=16
a=16÷8
a=2
Answer:
smaller x =-1/2
larger x = 7
Step-by-step explanation:
(x-7)(-4x - 2) = 0
Using the zero product property
(x-7)=0 (-4x - 2) = 0
x-7+7 = 0+7 -4x-2-2 =0+2
x=7 -4x =2
-4x/-4 = 2/-4
x = -1/2
