Answer: Mean = 760
Standard deviation = 6.16
Step-by-step explanation:
Given : The number of trials: 
The probability that a certain protection system will be recovered :
We know that the mean and standard deviation of binomial distribution is given by :_
, where n is the number of trials and p is the probability of success.
Now, the mean and standard deviation of the number of cars recovered after being stolen is given by :-
Hence, the mean is 760 and standard deviation is 6.16 .
You take turns plugging in each number for your answers. I’ll list them below.
6(0) - (0)2 = 0
6(1) - (1)2 = 4
6(2) - (2)2 = 8
6(3) - (3)2 = 12
6(4) - (4)2 = 16
6(5) - (5)2 = 20
6(6) - (6)2 = 24
The pattern I’ve noticed is every time you increase the value from the previous meaning for x, the solution increases by 4. I hope this helps and let me know if I’m right.
290 m2 you just have to add all of them
Separating the integral, we get the integral of 1/x minus the integral of 4/(x^2+1). From memory, I know that the integral of 1/x is ln(x). Next, I can separate the 4 from 4/(x^2+1), and I know from memory that the integral of 1/(x^2+1) is arctan(x). Therefore, your answer is ln(x)+C-4arctan(x)+C=ln(x)+4arctanx+C (Since C simply represents any number, we don't need to make it 2C. In addition, the C after 4arctan(x) and ln(x) could be different, so C-C would be some constant C too in this case)
NR = NS + SR = 18 + 45 = 63 m
If NPS~NQR then we can find QR:
Answer: C.
