Answer:
b. Binomial distribution.
Step-by-step explanation:
As a manufacturer is interested in the number of blemishes or flaws occurring every 100 feet of material which shows that only two possible outcomes with fixed number of trials are present here, so the probability distribution that has the greatest chance of applying to this situation is a binomial distribution that summarizes the possibility that a value will take one of two independent values under a provided set of parameters.
180 books because there's 6 shelves with 30 books on each shelf. 6×30=180 I believe that is the answer we are looking for.
Uhh, answer choices?
In any case, since
is inscribed in a semicircle, it is a right triangle (due to the inscribed angle theorem). Thus, by the Pythagorean theorem,
Now, the circumradius of a right triangle (the radius of the circle passing through all three of its vertices) is simply half its hypotenuse, so ![OJ=OK=OL=\frac{\sqrt{157}}{2}\approx \boxed{6.265}.](https://tex.z-dn.net/?f=OJ%3DOK%3DOL%3D%5Cfrac%7B%5Csqrt%7B157%7D%7D%7B2%7D%5Capprox%20%5Cboxed%7B6.265%7D.)
