Question

15 multiple choice 1 point attendance at museum x: age distribution the graph shows the percent distribution of visitors to museum x by age. if 553 people aged 20 years and older visited museum x, then how many total people visited the museum x? 700 2633 437 116

Explanation:

Step1: Find percentage of 20+ visitors

From the bar graph, the age groups 20 - 29, 30 - 39, 40 - 49, 50+ have percentages 19, 27, 25, 8 respectively. Sum these: \(19 + 27 + 25 + 8 = 79\%\).

Step2: Set up equation for total

Let total visitors be \(x\). Then \(79\%\) of \(x\) is 553, so \(0.79x = 553\).

Step3: Solve for x

\(x=\frac{553}{0.79}=700\).

Answer:

700
