Question

step 1 of 5: determine the missing value on the vertical axis represented by ?.
nba player scoring averages: 1999

Explanation:

Step1: Identify axis scale range

The vertical axis ranges from 0 to 30, with 5 evenly spaced intervals (including 0 and 30).

Step2: Calculate interval size

Divide total range by number of intervals:
$\frac{30 - 0}{5} = 6$

Step3: Find missing values

Each mark increases by 6 from the previous:
0, $0+6=6$, $6+6=12$, $12+6=18$, $18+6=24$, 30
The missing ticks (from bottom to top after 0) are 6, 12, 18, 24. Assuming [?] is the top missing tick before 30, it is 24.

Answer:

24
