2. In the data set below, what is the median? 9, 4, 9, 2, 8, 2,1
a. 9 b. 1 с. 2 d. 4​

d

Step-by-step explanation:

it's 4 because I'd you put the numbers from least to greatest its in the middle

2

Step-by-step explanation:

arrange the numbers in order

count how many numbers you have

if have ood number divide by 2 and round up to get the position of the median number

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
