Answer:
Sum of the interior angles = 2,880° Therefore, assuming a convex or regular polygon and using the summation formula (n - 2) 180°, we have
(n - 2) 180° = 2,880° Solve for n
n - 2 = 16 Add 2 to both sides of the equation
n = 18
Step-by-step explanation:
(n - 2) 180° = 2,880° Solve for n
n - 2 = 16 Add 2 to both sides of the equation
n = 18

Answer:
b) Chemistry
Step-by-step explanation:
To compare both scored we need to standardize the scores using the following equation:
![\frac{x-m}{s}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-m%7D%7Bs%7D)
Where x is the score, m is the mean and s is the standard deviation. So, 82 on chemistry is equivalent to:
![\frac{82-75}{15}=0.4667](https://tex.z-dn.net/?f=%5Cfrac%7B82-75%7D%7B15%7D%3D0.4667)
Because the mean of the scores on the chemistry final exam is equal to 75 and the standard deviation is 15
At the same way, 80 on Calculus is equivalent to:
![\frac{80-83}{13} =-0.2308](https://tex.z-dn.net/?f=%5Cfrac%7B80-83%7D%7B13%7D%20%3D-0.2308)
Because the mean of the scores on the calculus final exam is equal to 83 and the standard deviation is 13
Now, we can compare the values. So, taking into account that -0.2308 is lower than 0.4667, we can said that the student do better in Chemistry.
Answer:
Option 2
Step-by-step explanation:
Parallelograms have 2 parallel sides, and Option 2 proves that AB and DC are equal, which makes sides AD and BC Parallel according to lines AE and EC.
