Answer: 31
Step-by-step explanation:
Formula to find the sample size is given by :_

, where z*= critical value corresponds to confidence level.
= population standard deviation.
E= Margin of error.
As per given , we have

E=1
We know that critical value corresponding to 95% confidence level = z*=1.96
Then, the required sample size would be :



Hence, the required minimum sample size = 31
Answer:V=0.027 and 0.027<v
Step-by-step explanation:
So, 260 degrees is in the 3rd quadrant, only 10 degrees away from being straight down at 270 degrees....if you have a xy axis, and draw a line segment from the origin into the 3rd quadrant, then at the endpoint of that segment, draw back up to the x-axis, your reference angle is the angle that the line segment makes with the x-axis (in this case, the negative portion of the x-axis), which is 80 degrees....since 260 degrees is 80 degrees past 180.
So your answer is 80 degrees.

The third side cannot be 16 or greater than 16.
also it must be greater than 8 ( because 4+8 = 12 = the other sde)
The answer is B 8 < x < 16
