Answer:
Median = 2
Step-by-step explanation:
Median is basically what's the middle of a set of data.
There's a total of 9 numbers:
1.5, 1.5, 2, 2, 2, 2.5, 3, 3.5, 4
The repeated 2nd 2, is the median in this set of data.
Using the intersecting chord theorem:
15 x 2 = 5 x n
Simplify:
30 = 5n
Divide both sides by 5:
n = 30/5
n = 6 m
8 x n+8 = 16 x n+2
8n +64 = 16n +32
Subtract 8n from both sides:
64 = 8n +32
Subtract 32 from both sides:
32 = 8n
Divide both sides by 8:
n = 32 /8
n = 4
