games won by the stamford baseball team
year games won
2016 30
2017 42
2018 46
2019 37
2020 3
according to the table, when was the rate of decrease greater?
between 2018 and 2019
between 2017 and 2020

Explanation:

Step1: Calculate the rate of decrease between 2018 and 2019

The formula for the rate of decrease is \(\frac{\text{Initial value}-\text{Final value}}{\text{Initial value}}\).
Initial value (2018) \(= 46\), Final value (2019) \(= 37\)
Rate of decrease \(=\frac{46 - 37}{46}=\frac{9}{46}\approx0.196\)

Step2: Calculate the rate of decrease between 2017 and 2020

Initial value (2017) \(= 42\), Final value (2020) \(= 3\)
Rate of decrease \(=\frac{42- 3}{42}=\frac{39}{42}\approx0.929\)

Answer:

between 2017 and 2020
