The percent error is 53.3 %
<em><u>Solution:</u></em>
<em><u>The formula for percent error is given as:</u></em>
![Percent\ Error = \frac{\text{ l Experimental value - theoretical value l }}{\text{Theoretical value}} \times 100](https://tex.z-dn.net/?f=Percent%5C%20Error%20%3D%20%5Cfrac%7B%5Ctext%7B%20%20l%20Experimental%20value%20-%20theoretical%20value%20l%20%7D%7D%7B%5Ctext%7BTheoretical%20value%7D%7D%20%5Ctimes%20100)
From given,
A political analyst predicts Mr. Smith will only get 122 votes for mayor
Mr. Smith only gets 57 votes
Therefore,
Theoretical = 122
Experimental = 57
Thus we get,
![\text{Percent Error } = \frac{ | 57-122 | }{122} \times 100\\\\\text{Percent Error } = \frac{65}{122} \times 100\\\\\text{Percent Error } = 0.5327 \times 100\\\\\text{Percent Error } = 53.28 \approx 53.3](https://tex.z-dn.net/?f=%5Ctext%7BPercent%20Error%20%7D%20%3D%20%5Cfrac%7B%20%7C%2057-122%20%7C%20%7D%7B122%7D%20%5Ctimes%20100%5C%5C%5C%5C%5Ctext%7BPercent%20Error%20%7D%20%3D%20%5Cfrac%7B65%7D%7B122%7D%20%5Ctimes%20100%5C%5C%5C%5C%5Ctext%7BPercent%20Error%20%7D%20%3D%200.5327%20%5Ctimes%20100%5C%5C%5C%5C%5Ctext%7BPercent%20Error%20%7D%20%3D%2053.28%20%5Capprox%2053.3)
Thus percent error is 53.3 %

The function is: g ( x ) = 6^x
Section A: from x = 1 to x = 2
g ( 1 ) = 6, g ( 2 ) = 36
Average rate of change:
( 36 - 6 ) / ( 2 - 1 ) = 30 / 1 = 30
Section B : from x = 3 to x = 4
g ( 3 ) = 6^3 = 216, g ( 4 ) = 6 ^4 = 1296
Average rate of change:
( 1296 - 216 ) / ( 4 - 3 ) = 1080 / 1 = 1080
1080 : 30 = 36
Average rate of change of Section B is 36 times greater than the Section A.
This is because the function is exponential.
Answer:
18. 28 cm*2
19. 24 m
Step-by-step explanation:
18. length × l = 16
l*2= 16
l = 4
RQ = 4 cm
PR =7cm
Area of parallelogram = b×h
= 7×4
=28cm*2
19. 8 +8 + (6-2) +( 6- 2)
=24 m
