The table below shows field goal statistics for three different kickers
FromTheMoon [43]

Answer:

<h2>From least to greatest: C, B and A</h2>

Step-by-step explanation:

To order each Kicker correctly, we have to find the success rate of each one, which is obtained by dividing and then multiplying by 100 to obtained the percentage:

R=\frac{made}{attempted}

<h3>Success rate of A:</h3>

R_{A}=\frac{12}{14}.100=86\%

<h3>Success rate of B:</h3>

R_{B}=\frac{15}{18}.100=83\%

<h3>Success rate of C:</h3>

R_{C}=\frac{19}{24}.100=79\%

So, comparing all three, from least to greatest we have:

C with 79%, then B with 83%, and A with 86%.
