Answer:
x = 7
Step-by-step explanation:
The equation can be rewritten to ...
8x = 13n +4 . . . . for some integers x and n
x = (13n +4)/8
For x to be an integer, 13n must be an odd multiple of 4. Since 13 is an odd number, n=4 will do.
x = (13·4 +4)/8 = 56/8
x = 7
__
The graph shows a "trial and error" method of solution. Only values of x less than 13 need to be examined.
Answer: 0.14
Step-by-step explanation:
Given: Mean :
In minutes , Mean :
The exponential distribution function with parameter is given by :-
The probability of waiting more than 30 seconds i.e. 0.5 minutes is given by the exponential function :-
Hence, the probability of waiting more than 30 seconds = 0.14
