The mean represents the central value of a data set and is calculated by summing all the numbers and dividing by the count of numbers. In this problem, the given numbers are <strong>18, 1, 24, and 18<\/strong>.<\/p>\n\n\n\n<p>We start by adding them together:<br>[<br>18 + 1 + 24 + 18 = 61<br>]<br>Next, we count how many numbers there are: <strong>4<\/strong>. To find the mean, we divide the sum by this count:<br>[<br>61 \\div 4 = 15.25<br>]<br>Rounding to the nearest tenth follows a simple rule:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>If the hundredths digit (second decimal place) is <strong>5 or more<\/strong>, round up.<\/li>\n\n\n\n<li>If it is <strong>less than 5<\/strong>, round down.<\/li>\n<\/ul>\n\n\n\n<p>In <strong>15.25<\/strong>, the hundredths digit is <strong>5<\/strong>, so we round <strong>15.25 up to 15.3<\/strong>.<\/p>\n\n\n\n<p>Thus, the correct answer is <strong>B) 15.3<\/strong>.<\/p>\n\n\n\n<p>Understanding how to calculate and round the mean is useful in real-life applications such as analyzing data in business, finance, and research. It helps summarize large data sets into a single representative number, making it easier to compare different groups or trends over time.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>18, 1, 24, 18 (Round to the nearest tenth, if necessary.)A) 20.7B) 15.3C) 13.8D) 15.8 The correct answer and explanation is : To determine the correct answer, we first find the mean (average) of the given numbers: 18, 1, 24, and 18.
