Answer:
+ 3
+ 2x
Step-by-step explanation:
x(x^2 + x + 2x + 2)
x ( x^2 + 3x + 2)
+ 3
+ 2x
This is an linear equation, so
y=mx + b
m= money w=weeks
m= -20w +200
Answer:

And we can use the cumulative distribution function given by:

And for this case we can write the probability like this:

And then the final answer for this case would be 
Step-by-step explanation:
For this case we define our random variable X "price of gasoline for a city in the USA" and we know the distribution is given by:

And for this case the density function is given by:

And we want to calculate the following probability:

And we can use the cumulative distribution function given by:

And for this case we can write the probability like this:

And then the final answer for this case would be
