The lifespans of meerkats in a particular zoo are normally distributed. The average meerkat lives 13.113.113, point, 1years; the standard deviation is 1.51.51, point, 5 years.
Use the empirical rule (68−95−99.7%)(68−95−99.7%)left parenthesis, 68, minus, 95, minus, 99, point, 7, percent, right parenthesis to estimate the probability of a meerkat living longer than 14.614.614, point, 6 years.

A 33.153 mg sample of a chemical known to contain only carbon, hydrogen, sulfur, and oxygen is put into a combustion analysis apparatus, yielding 59.060 mg of carbon dioxide and 24.176 mg of water. In another experiment, 21.223 mg of the compound is reacted with excess oxygen to produce 9.1726 mg of sulfur dioxide. Add subscripts below to correctly identify the empirical formula of this compound (use this order of elements: CHSO)
