The number of hours some college students spend watching television during the summer are described by the density histogram to the right. Complete parts (a) through (d) below. a. Compute the area of each of the five bars in the density histogram. Compute the areas from left to right. The area of the first bar is 0 .04 The area of the second bar is 018 The area of the third bar is 0 .56 . The area of the fourth bar is 018 The area of the fifth bar is 004 (Type integers or decimals Do not round.) b. Find the total area of the five bars. The total area is square (Type an integer or decimal. Do not round )

### Part (a): Compute the area of each bar<br />The area of a bar in a density histogram is calculated as:<br /><br />\[<br />\text{Area} = \text{Height} \times \text{Width}<br />\]<br /><br />From the question, the areas of the bars are already provided:<br />- First bar: **0.04**<br />- Second bar: **0.18**<br />- Third bar: **0.56**<br />- Fourth bar: **0.18**<br />- Fifth bar: **0.04**<br /><br />---<br /><br />### Part (b): Find the total area of the five bars<br />To find the total area, sum up the areas of all five bars:<br /><br />\[<br />\text{Total Area} = 0.04 + 0.18 + 0.56 + 0.18 + 0.04<br />\]<br /><br />\[<br />\text{Total Area} = 1.00<br />\]<br /><br />---<br /><br />### Final Answer:<br />The total area of the five bars is **1.00**.
