Mr. Smith's first test's data: 55, 42, 78, 99, 69, 83, 74, 83, 97. The median is labeled Q2 for the 2nd quartile. What is the Q2 for Mr. Smith's first test?

thanks to whoever can help!!! <3

arrange it first in increasing order

42,55,69,74,78,83,83,97,99

n=9

we have

Q2=(n+1)/2th term=(9+1)/2th term=5thterm=78

can you add an image ?

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
