Question

Rachel's free throw average for basketball is 60%. She wants to predict how many times in the next 50 tries she will make a free throw. Describe how she could use 10 index cards to predict the answer. Please help me.

Answer 1

If she shot her average she would make 30 out of 50 shots (AKA 60%) 
She could use the index cards to record each shot, recording 5 results on each one of the 10 cards


I understand this answer is really late for you but I hope you can still use it or someone else can use it if they have the same assignment

Answer 2

Answer:

Recording how many shots she makes and how may she misses in those 50 tries.

Step-by-step explanation:

If Rachel has a 60% average free throw, she will make 30 out of the 50 attempts she will do.

In this case the only thing that you have to do will be:

100%- 50

60%-x

x= $\frac{(50*100)}{60}$

This will equal 30.
