Answer:
Step-by-step explanation:
Sorry, I could do only the first three questions
Well, an interior angle plus an exterior angle has to equal 180°. Also, the sum of the interior angles is represented by this formula: [-2 + n]180, whereas the sum of the exterior angles all add up to 360°, and is represented by this formula: 360/n [let "n" represent the number of sides in every polygon].
Where is the rest of the question?
Answer:
9 degrees celsius
Step-by-step explanation:
All you have to do is 7 - (-2) = 9.
Answer:
B) Yes, because the proportion of the sample whose favorite pizza is pepperoni is about 27%.
Step-by-step explanation:
From data of survey we can estimate the proportion of the sample whose favorite pizza is pepperoni. That is 40 (say pepperoni is the favorite) from 150 (total of sample).
Proportion would be
that is 27%.
Now we can calculate 27% of total of residents (2,800). We should multiply 27% by 2,800.
which is close to 750.
So we can conclude that yes, 750 is a reasonable estimate because the proportion of the sample whose favorite pizza is pepperoni is about 27%
