(0, 2, 15, 16, 17) 0+2+15+16+17 = 50 50/5 = 10 The median is 15, the mean is 10.
13 - if there is no "middle" number then you take the average of the 2 either side of where the middle would have lain.
2/5 + 2/3 = 6/15 + 10/15 = 16/15 = 1 1/15
To find the average or mean - Add all the numbers together and divide by the amount of numbers you added: So 16 + 29 + 15 = 60 (1) (2) (3) <- So 3 numbers added together 60 / 3 = 20. So the average of 16, 29, and 15 is 20.
add them all up and divide by 2 ! 7+14+10+14+29+16+15=? ?/2=? Answer:52.5->53
The mean (average) is 8. 6+10= 16 16/2(numbers being added)= 8
-15/10 + 16/10 = 1/10
The series 1 6 10 13 15 (1+5=6; 6+4=10, 10+3=13; 13+2=15) is completed by 15+1=16. The answer is 16.
2/3 + 3/5 =10/15 + 9/15= 19/15(19/15) / 2 = 19/3019/30
10 30 15 16 48 24 25 x3 1/2 +1 x3 1/2 +1
5 + 10 = 15. To take the average, add all the units to be averaged, then divide that number by the number of units, in this case, 2. So, 15/2 = 7-1/2 or simply, 7.5.
If you go 2 miles in 5 mins and then 2 miles in 10 mins, you have gone 2 + 2 = 4 miles in 5 + 10 = 15 mins 60 min = 1 hours → 15 min = 15/60 hr = 1/4 hr speed = distance ÷ time → speed = 4 miles ÷ 1/4 hr = 4 × 4/1 mph = 16 mph.
