Answer: 215.6 meters
Step-by-step explanation:
Formula of a polygon: A= 1/2ap
a = apothem
p = perimeter
Since the polygon has 7 sides, you need to multiply 7 by 7.7 (side length) to find the perimeter which would be 53.9
A= 1/2 x 8 x 53.9
A = 215.6 meters
Answer:
218 and 314 days
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 266
Standard deviation = 16
About 99.7% of all pregnancies last between what interval?
Within 3 standard deviations of the mean. So
266 - 3*16 = 218 days
266 + 3*16 = 314 days
218 and 314 days
Answer:
Answer is 
Step-by-step explanation:
It is 29 in place of 27 . and Its a geometric series with first term 27 and common ratio 
and general formula for given sequence is given by 
so plugging the value of a and r ,we get
![27 ([tex]\frac{1}{3}](https://tex.z-dn.net/?f=27%20%28%5Btex%5D%5Cfrac%7B1%7D%7B3%7D)
)^{n-1}[/tex]
Type in math papa it gives you all the answers I promise!!!....
