In a recent survey, 64 % of the community favored building a police substation in their neighborhood. If 14 citizens are chosen,

kozerog [31]

Answer: 0.1840

Step-by-step explanation:

The binomial probability formula :-

$P(X)=^nC_x\ p^x(1-p)^{n-x}$ , here n is the number total of trials , p is the probability of getting success in each trial and P(x) is the probability of getting success in x trial.

Given : The probability of the community favored building a police substation in their neighborhood = 0.64

If 14 citizens are chosen, then the probability that exactly 8 of them favor the building of the police substation will be :-

$P(8)={14}^C_{8}\ (0.64)^{8}(1-0.64)^{14-8}\\\\=\dfrac{14!}{8!6!}\times(0.64)^8(0.36)^{6}\\\\0.183996740126\approx0.1840$

Hence, the probability that exactly 8 of them favor the building of the police substation = 0.1840

What is the general form of the equation for the given circle centered at O(0, 0)?

eduard

The general form of such an equation is
x^2 + y^2 = r^2 where r = radius

In this case r^2 = 4^2 + 5^2 = 41

So the required equation is x^2 ^ y^2 = 41

Point Z is translated right 1,done 8. Which is the coordinate pair for the translated point Z. A.(1.4) B.(1,-4) C.(4,-1) D.(-8,1

nikdorinn [45]

Assuming point Z is at the origin (0,0), you move from the origin over to the right one, and go down 8.
Therefore you would be at point (1,-8) answer D
