Answer:
Ir is impossible to tell.
Step-by-step explanation:
We are given that,
Stan earns $15 on Monday, $45 on Tuesday, Wednesday and Thursday and $60 from Monday to Friday this week.
Since, we do not have the individual earnings for each day, we are unable to plot the graph of the given relationship.
So, without graph it is impossible to state whether the relationship is linear or not.
Well, to write the definition of "Perpendicular lines form right angel" using "if and only if". the sentence would become :
<em>
</em><em>Two lines are perpendicular if and only if they form a right angle
</em><em>
</em><em />Hope this helps
Answer : The percentage error will be, 45.5 %
Step-by-step explanation :
To calculate the percentage error, we use the equation:
![\%\text{ error}=\frac{|\text{Experimental value - Accepted value}|}{\text{Accepted value}}\times 100](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20error%7D%3D%5Cfrac%7B%7C%5Ctext%7BExperimental%20value%20-%20Accepted%20value%7D%7C%7D%7B%5Ctext%7BAccepted%20value%7D%7D%5Ctimes%20100)
We are given:
Experimental value = 16 inches
Accepted value = 11 inches
Now put all the given values in above equation, we get:
![\%\text{ error}=\frac{|16-11|}{11}\times 100\\\\\%\text{ error}=45.5\%](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20error%7D%3D%5Cfrac%7B%7C16-11%7C%7D%7B11%7D%5Ctimes%20100%5C%5C%5C%5C%5C%25%5Ctext%7B%20error%7D%3D45.5%5C%25)
Hence, the percentage error will be, 45.5 %
