Answer:
14.5 =x
Step-by-step explanation:
Since this is a right triangle we can use trig functions
sin theta = opposite side/ hypotenuse
sin A = BC / AB
sin 65 = x /16
Multiply each side by 16
16 sin 65 =x
14.50092459 =x
14.5 =x
<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>
