Answer:
Prob.3
Denote r: radius of circle O
Formula for calculating AOB sector:
Area = pi*r^2*angle/360
Area = pi*r^2*45/360 = 18 pi
=> r^2 = 18*360/45 = 144
=> r = 12
For prob.4, give it a try, follow the formula I gave. Good luck !
(answer : r = 6)
The correct answer would be A. x=20/3 because it is proportional.<span />
Answer:
A. The standard deviation is np(1 - p).
Step-by-step explanation:
The variance of the number of successes/failures is measured by (σ2x) is n * P * ( 1 - P ).
The standard deviation (σx) is square root of [ n * P * ( 1 - P ) ]
The mean is np.
