Answer:
The probability that at most 6 will come to a complete stop is 0.7857.
Step-by-step explanation:
Let <em>X</em> = number of drivers come to a complete stop at an intersection having flashing red lights in all directions when no other cars are visible.
The probability of the event <em>X</em> is, P (X) = <em>p</em> = 0.25.
The sample of drivers randomly selected is of size, <em>n</em> = 20.
The random variable <em>X</em> follows a binomial distribution with parameters <em>n</em> = 6 and <em>p</em> = 0.25.
The probability function of Binomial distribution is:

Compute the probability that at most 6 will come to a complete stop as follows:
P (X ≤ 6) = P (X = 0) + P (X = 1) + P (X = 2) + P (X = 3)
+ P (X = 4) + P (X = 5) + P (X = 6)

Thus, the probability that at most 6 will come to a complete stop is 0.7857.

Answer:
6
Step-by-step explanation:
The length form -1 to 2 is 3
The length from -3 to 2 is 5
√3²+5² = √9+25 =√36=6
The Domain (x-values and independent variable) would be the time of day
The Range (y-values and dependent variable) would be the amount of people in a movie theater
Answer:
To get the x-intercepts of the function, f(x) = 4x2 – 24x + 20
It has to be equated to zero and the values of x are the x-intercepts. So,
4x2 – 24x + 20 = 0
The resulting equation is a quadratic equation which can be solved by different methods. The solution is
x = 5, 1
The average therefore is:
(1+5/)2 = 3
