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
R = d/t
r= 4/50
r = 0.08
A. 0.08 kilometers per minute
Let's change all of them into seconds so it is easier to compare:
Pamela: 51 seconds.
Lucy: 3/5 minute x 60 = 36 seconds
Kady: 8 minutes x 60 = 480 seconds
Thus, Kady can stay underwater the longest.
1/10 of 300 is 30 so June has $30. If June has 10 times as much as Marie then Maria has 1/10 of what June has and 1/10 of 30 is 3 so Marie has $3.
