Answer :
Answer:
Mariana has better performance.
Step-by-step explanation:
We are given that in a training session, Mariana made 12 of the 15 shots on goal that she kicked and Carla had an effectiveness of 75%.
And we have to find which girl's performance is better.
Since it is stated that Carla had an effectiveness of 75%.
Similarly, we will find the effectiveness of Mariana;
Total shots available to Mariana = 15 shots
Number of shots on goal = 12
So, her effectiveness = [tex]\frac{12}{15} \times 100[/tex]
= [tex]4 \times 20[/tex] = 80%
This shows that Mariana has a better performance as compared to Carla as 80% > 75%.
