Answer:
The median height of Sam and his brothers is 135.
Step-by-step explanation:
First, let's find the age of Sam's brothers:
[tex] B_{1} = 140 cm - 5 cm = 135 cm [/tex]
[tex] B_{2} = 140 cm - 7 cm = 133 cm [/tex]
The median height of Sam and his brothers is given by the middle number of the three values arranged from lowest to highest:
133 135 140
Since the middle number is 135, then the median height is 135.
Therefore, the median height of Sam and his brothers is 135.
I hope it helps you!
