Answer:
4004
Step-by-step explanation:
The number of combinations of choosing r objects from a group of n is nCr.
So the number of ways to get 7, 8, 9, or 10 heads from 13 coin tosses is:
₁₃C₇ + ₁₃C₈ + ₁₃C₉ + ₁₃C₁₀
= 1716 + 1287 + 715 + 286
= 4004
Answer:
$6
Step-by-step explanation:
Divide 1.80 by 3, then multiply that answer by 10.
8-the formula to find an exterior angle of a polygon is:
360/n
(n is the number of sides of the polygon)
so the answer is 40
![\frac{360}{9} = 40](https://tex.z-dn.net/?f=%20%5Cfrac%7B360%7D%7B9%7D%20%20%3D%2040)
9 - the formula to find an interior angle of polygon is:
![\frac{(n - 2) \times 180}{n}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%28n%20-%202%29%20%5Ctimes%20180%7D%7Bn%7D%20)
so the answer is 135
![\frac{(8 - 2) \times 180}{8} = \frac{6 \times 180}{8} = \frac{1080}{8} = 135](https://tex.z-dn.net/?f=%20%5Cfrac%7B%288%20-%202%29%20%20%5Ctimes%20180%7D%7B8%7D%20%20%3D%20%20%5Cfrac%7B6%20%5Ctimes%20180%7D%7B8%7D%20%20%3D%20%20%5Cfrac%7B1080%7D%7B8%7D%20%20%3D%20135)
good luck
