1. use the table below to determine a reasonable prediction of the number of votes for ice cream out of the next 270 votes.\n| dessert | votes |\n| ---- | ---- |\n| pie | 4 |\n| ice cream | 11 |\n| cake | 8 |\n| cookies | 7 |
Answer
Explanation:
Step1: Calculate total votes
$4 + 11+8 + 7=30$
Step2: Find proportion of ice - cream votes
The proportion of ice - cream votes is $\frac{11}{30}$.
Step3: Predict number of ice - cream votes in 270 votes
Let $x$ be the number of ice - cream votes in 270 votes. We set up a proportion: $\frac{11}{30}=\frac{x}{270}$. Cross - multiply gives $30x = 11\times270$. Then $x=\frac{11\times270}{30}=99$.
Answer:
99
