emmy is tossing bean bags at a target. she hit the target on 9 out of her last 18 tries. considering this data, how many hits would you expect emmy to get during her next 16 tosses? hits
Answer
Explanation:
Step1: Calculate the hit - rate
The hit - rate is the number of hits divided by the number of tries. The hit - rate $r=\frac{9}{18}=\frac{1}{2}$.
Step2: Predict the number of hits
Multiply the hit - rate by the number of future tries. Let $n$ be the number of expected hits in 16 tries. Then $n = r\times16$. Substitute $r=\frac{1}{2}$ into the formula, we get $n=\frac{1}{2}\times16 = 8$.
Answer:
8
