Use the table to estimate how long it took Stella Pajunas to type 100 words

# of words: 36 72 108 144 180 216
# of sec: 10 20 30 40 50 60

Its a nice linear line, so no statistical estimation technique required.
For every 10 seconds, Stella can type 36 words. So 36 is to 10 as 100 is to X. That is (36/10)=(100/X). solve for X

To estimate how long it took Stella Pajunas to type 100 words based on the table, we need to find the corresponding time in seconds.

From the table, we can see that for every 10 seconds, Stella can type 36 words. So, we can set up a proportion to solve for the unknown time:

36/10 = 100/X

To solve for X (the time in seconds it took Stella to type 100 words), we can cross-multiply and then divide:

36X = 10 * 100

36X = 1000

X = 1000 / 36

X ≈ 27.78

Therefore, it would take approximately 27.78 seconds for Stella Pajunas to type 100 words based on the given data.
