Answer:
N = 16 measurements
Step-by-step explanation:
A method produces a random error for each measurement of 4%
A percent error of equal to or less than 1% is required.
We want to find out the minimum number of measurements that must be collected.
The standard error is given by
Where s is the standard deviation and N is the number of measurements.
We are given standard deviation equal to 4% and SE equal to 1%
So re-arranging the above equation for N
Therefore, a minimum 16 number of measurements are needed.

Step-by-step explanation:
Part 1
<h3>Answer: -9</h3>
---------------------------
Explanation:
Let's focus on evaluating first. We need to look at the table and locate f(x) = 13. So we're looking in the f(x) row where 13 shows up. That's in the second to last column. Right above that we have x = 5
This means f(5) = 13 and . The inverse undoes the f(x) function. So the input x and output y values swap places. This is why we're reading the table in reverse.
We can replace all of with 5 to go from to
Then we repeat the process of using the table. Locate 5 in the f(x) row. This is in the last column. The value above that is x = -9
So f(-9) = 5 and
Overall,

Part 2
<h3>Answer: -13</h3>
---------------------------
Explanation:
Same idea as before. Locate 8 in the f(x) row. The value above this is x = -13
This means f(-13) = 8 and
