Answer:
a) F(t) = R[P(t)]
b) the output units of the new function = F(t) in dollars per gallon
Step-by-step explanation:
a) There are two function R(t) which shows the average price in dollars of a gallon of regular unleaded gasoline and P(t) which shows the purchasing power of the dollar as measured by consumer prices based on 2010 dollars.
To write the function which gives the rice of gasoline in constant 2010 dollars ;
From the analysis , this is an example of a composition of function as such the relationship =
F(t) = R[P(t)]
b) the output units of the new function = F(t) in dollars per gallon
This shows that the value of F(t) is the dependent variable

3) Place the decimal point right under the placement of the decimal point of the problem
Answer:
0.2 then 2 then the graph
Step-by-step explanation:
Answer:
The 99% confidence interval for the mean distance from home to work for all residents of this state is between 8.49 and 9.19 miles.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Z-table as such z has a p-value of 
.
That is z with a pvalue of 
, so Z = 2.575.
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 8.84 - 0.35 = 8.49 miles.
The upper end of the interval is the sample mean added to M. So it is 8.84 + 0.35 = 9.19 miles.
The 99% confidence interval for the mean distance from home to work for all residents of this state is between 8.49 and 9.19 miles.
