Answer:

5.104%

Step-by-step explanation:

Given:

The accepted value for the mass density = 4.80 g/cc

Observed values:

5.13 g/cc

4.98 g/cc

5.06 g/cc

5.01 g/cc

Total number of observed values = 4

Mean of the observed values = ( 5.13 + 4.98 + 5.06 + 5.01 ) / 4 = 5.045 g/cc

Now,

The percentage error is calculated as:

\textup{Percent Error}=\frac{\left |\textup{Accepted value-Mean value} \right |}{\left |\textup{Accpeted value} \right |}\times100%

on substituting the values, we get

\textup{Percent Error}=\frac{\left |4.80-5.045\right |}{4.80}\times100%

or

Percentage error = 5.104%

If f (1)= -2, then the point is on the graph of f
Komok [63]
<h3>Answer:  (1, -2)</h3>

Explanation:

Writing f(1) = -2 means x = 1 and y = f(x) = -2 pair up together

So we have (x,y) = (1, -2) as the point on the f(x) curve.
