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 .
The formatting was a bit confusing, so please do let me know if this isn't the correct equation for the sequence.
The first term is given, which is
Now, use the equation for the next terms:
Thus, the first 4 terms are -9, -8, -6, and -3. Let me know if you need any clarifications, thanks!
The answer is (-1,2). Choise B
Put both values into a ratio
P:B
28:79
95°.
Since the angle inside of a triangle equal 180° we need to find the angles inside of the triangle. The two angles on a line add up to 180° or are supplementary, so we can find the inside angle x by doing 180-150=30°.
Now that we know inside x is 30, if we add 30+65, we get 95, and 180-95=85°. Then to find angle xzw, just do 180-85 to get 95°.
Hope this helps :)
