Im unsure about g(f(4)) though.
Answer:
$26.3 night-time rest days
Range is $33.19
Step-by-step explanation:
We need to find the mean of the standard cost to find the night-time rest days:

So, the required mean is : 



After simplification we will get the night-time rest days price which is: $26.3
Now, we will find the range in cost of stays in standard price and with breakfast price which is difference between the maximum cost minus the lowest cost
So, the sum of Standard cost is: $103
And the sum of Breakfast price cost is: $136.19
So, the required range is: $136.19-$103=$33.19
Answer:
Positive linear.
Step-by-step explanation:
The points are gradually rising as x increases.
1700000000You see there is no decimal... so we have to put one. Whenever there is no decimal, its just add the end ;)
Now our number has to be greater then 1 but less than 0.
So as you can see 17 is greater then 10. So what about 1.7? Yes thats greater then one but less than 0!
So lets see how many spaces it takes to move the decimal there.
I got 9.
So then we do this:
1.7*10^9
Got it?
9.71
so round up
to
10..............................................
