Question

lonnie threw 50 free throws and missed 16 of them. if lonnie throws 75 free throws, what can be predicted about the number she will make successfully?
lonnie will make 24 free throws.
lonnie will make 51 free throws.
lonnie will make 59 free throws.
lonnie will make 66 free throws.

Explanation:

Step1: Calculate success - rate for 50 throws

First, find the number of successful throws out of 50. The number of successful throws out of 50 is $50 - 16=34$. The success - rate $r$ is $\frac{34}{50}=0.68$.

Step2: Predict successful throws for 75 throws

Multiply the success - rate by the number of throws. If the number of throws is $n = 75$, the predicted number of successful throws $s$ is $s=r\times n=0.68\times75 = 51$.

Answer:

B. Lonnie will make 51 free throws.
