We are given with
x = 15%
n = 14

and asked to get the probability that none are turned to the show
u = 0

Using the formula for the z-score
z = x - u / s
where x and u are given
s is supposed to be given as well

If there is a value of s, substitute the values and solve for z
Then, refer to the z-score table (one-tailed) to determine probability basin on the z-score.

Tell me the answer of these question.

Nonamiya [84]

$16. \ \ V= \pi r^2h \ \to \ r^2= \cfrac{V}{ \pi h} \ \to \ \boxed{r= \sqrt{ \frac{V}{ \pi h} } } \\ \\ \\ 17.\ \ d= \frac{1}{2} at^2 \ \to \ 2d= at^2 \ \to \ t^2= \cfrac{2d}{a} \ \to \ \boxed{t= \sqrt{\frac{2d}{a}}} \\ \\ \\ 18. \ \ S=180(n-2) \ \to \ \cfrac{S}{180}=n-2 \ \to \ \boxed{n= \frac{S}{180}+2 }$
