Answer:
45 degrees
Step-by-step explanation:
The formula to find the sum of all the interior angles in an "n-gon" (n is a variable that stands for the numbers of sides, ex) 20-gon --> 20 sided polygon) is .
Let's plug in 100 to find the sum of all the interior angles in a 100-gon.
I would rather distribute than simplify the parentheses and have to multiply 180 by 98.
So:
= degrees
[REMEMBER, IT WAS NOT GIVEN THAT THIS POLYGON IS REGULAR, SO <u>DO NOT</u> DIVIDE 17640 BY 100]
Now to find the last angle, we can just subtract since we are given the value of 99 of the 100 angles (17595 degrees).
So the last angle is degrees
Answer:
6
Step-by-step explanation:
5+1
a negative and a negative make a positive.
=6
Let the price before increase be Rs.100
Then , as the tpercentage increase =25%
Therefore, increase in price =
100
25
×100
=Rs.25
Therefore increased price =Rs.125
Therefore the percentage by which house wife should decrease the consumption be(
125
25
×100)%
=20%
I believe its C. Hope it helps lad
Answer:
b. We are 95% confident that the proportion of coworkers who went on a vacation last year away from home for at least a week is between 50% and 66%.
Step-by-step explanation:
A confidence interval at the level of x% for a proportion being between a and b means that we are x% sure that the true proportion of the population is between a and b.
In this problem, we have that:
95% C.I is (0.5, 0.66)
Interpretation: 95% confident that the true proportion is between 0.5 and 0.66.
The correct answer is:
b. We are 95% confident that the proportion of coworkers who went on a vacation last year away from home for at least a week is between 50% and 66%.
