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
The number is irrational, which means those y values in the table are irrational as well. So there's no way to get exact fractions for any of the decimal values.
The next best thing is to get approximate fractions.
A number like 4.1548 is the same as
Then we can say:
Optionally we can reduce that if you wanted.
So the fraction 41548/10000 turns into the decimal 4.1548
The other decimal values are handled in a similar fashion.
I'm not sure why your teacher wants you to work with fractions. It's better if somehow you can type in the coordinate values as they appear in decimal form.
