The distribution of images on the pages of a 350-page catalog is found to follow normal distribution with a mean of 32 images pe
r page and a standard deviation of 8 images per page. Which conclusion does this information best support? Approximately 238 pages fall within the first standard deviation of the mean. Approximately 238 pages fall within the second standard deviation of the mean. Approximately 238 pages fall within the third standard deviation of the mean. Approximately 346 pages fall within the second standard deviation of the mean. Approximately 332 pages fall within the third standard deviation of the mean. NextReset
<span>Approximately 238 pages fall within the second standard deviation of the mean. The 68-95-99.7 rule gives that in a normal distribution, about 68% of the data fall within the first standard deviation, and 350*0.68=238. 350*0.95=332, so about 332 pages fall within the second standard deviation, and 350*99=348.95 pages fall within the third standard deviation.</span>
the actual way of writing sin inverse is arcsine, not sin⁻¹
since the output of sin is from -1 to 1, the domain of arsince is from -1 to 1. This is different than 1/sin(x), whose domain is all real numbers. we now write sin⁻¹ to fit it on the tiny buttons on our calculators
