Answer: The value of n is 321.
Step-by-step explanation:
Since we have given that
Sample size = 321
Percentage of them developed headaches = 7%
So, the value of p would be
Now, the value of q would be
And the mean for the number of subjects who develop headaches would be
and the standard deviation would be
Hence, the value of n is 321.

Their are 6 equilateral triangles in a regular hexagon:
The area of one triangle = (x²√3)/4, then:
1st answer: The area of the hexagon base: is 6 TIMES the area of one equilateral triangle [or, needed for 2nd, question, TOT AREA:(6x²√3)/4] = (3x²√3)/2] unit²
2nd answer: :
Volume of pyramid: (base area)(height)/3
Volume of pyramid: (3x²√3).(3x)/3 (because height = 3x, given)
Then Volume of pyramid= 3x³√3 unit³.
3 is the answer for the second question
