Area = 3.14 * r^2
= 3.14 * 121 = 379.9
The ratios are 5/2 adn 25/4 for the perimeter and area respectively
Answer:
The probability that the difference between the sample mean
and the true population mean
is : ![P[|\bar{x}-\mu|\leq0.7]=0.9876](https://tex.z-dn.net/?f=P%5B%7C%5Cbar%7Bx%7D-%5Cmu%7C%5Cleq0.7%5D%3D0.9876)
Step-by-step explanation:
Given :
Population standard deviation
.
Sample size 
The sample mean standard deviation
To find :
The probability that the difference between the sample mean
and the true population mean 

Now, the probability that the difference between the sample mean
and the true population mean
is :
,
is large 



Therefore, the probability ![P[|\bar{x}-\mu|\leq0.7]=0.9876](https://tex.z-dn.net/?f=P%5B%7C%5Cbar%7Bx%7D-%5Cmu%7C%5Cleq0.7%5D%3D0.9876)
Law of sines,. a/sinA = b/sinB = c/sinC
25/sin44 = c/sin88. Angle C is 88° because the three angles of any triangle add to 180°
now a little Algebra gives us that
25(sin88)/sin44 =35.966 so B is our answer
