This is done by adding the hours for each day, making sure to include days when she didn\u2019t dance (in this case, Wednesday, which contributes 0 hours).<\/p>\n\n\n\n<p>Next, since the average is the total amount spread evenly over the whole time period, we divide the total hours by the number of days in the week \u2014 7. This division tells us how many hours she danced per day on average.<\/p>\n\n\n\n<p>After division, we get a decimal number representing the average hours. Because the question asks for rounding to the nearest tenth, we look at the decimal places to round correctly. Here, the average is approximately 1.64 hours per day, which rounds to 1.6 hours.<\/p>\n\n\n\n<p>This average helps us understand Jenna\u2019s dancing habits over the whole week as a single number, smoothing out the days when she danced more or less. Even though she had days with no dancing, the average gives a good summary measure of her overall dancing activity across the seven days.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Jenna dances for 3 hours on Sunday, 2 hours on Monday and Tuesday, 1 hour on Thursday, 1.5 hours on Friday, and 2 hours on Saturday.
