The model height and range of heights 1.35, 1.25, 1.35, 1.40, 1.35, 1.50, 1.35, 1.50, and 1.20 are m and r respectively. Find m+2r.
Answer Details
To find the value of m+2r, we first need to find the value of m and r.
m is the model height, which is simply the average of the given heights:
m = (1.35 + 1.25 + 1.35 + 1.40 + 1.35 + 1.50 + 1.35 + 1.50 + 1.20) / 9
m = 1.35
r is the range of heights, which is the difference between the highest and lowest height:
r = 1.50 - 1.20
r = 0.30
Now we can calculate m+2r:
m+2r = 1.35 + 2(0.30)
m+2r = 1.95
Therefore, the value of m+2r is 1.95.
