To answer this (specifically the first one) you have to count how many spaces each point moves. (How many spaces up/down does it go? Left/right?) then you put rise (up/down) over run (left/right) and you should get the slope!
I think the probability of picking an odd number is 7/15
Answer:
6d + 6 or 6(d + 1)
Step-by-step explanation:
4d + 6 + 2d
Collect like terms
4d + 2d + 6
= 6d + 6
It can also be written as
6(d + 1) by factorisation
6d + 6 or 6(d + 1)

Answer:
The probability density function for the average length of life of the two components is 
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following probability density:

In which
is the decay parameter.
Each missile has a length of life governed by the exponential distribution with mean 1 (with measurements in hundreds of hours). Find the probability density function for the average length of life of the two components.
2, each with mean 1 means that 
So the probability density function is:
