Answer:
Area of sector = 84.861
Step-by-step explanation:
Given
The radius of the circle = 9
central angle of sector = 
value of pi π = 3.143
To find : the area of sector = ?
We know that the formula to calculate area of sector is given as:
area of sector = (π 
Θ)/ 
where, r is radius and Θ is the central angle of the sector
Substituting the known values in above formula, we get
area of sector = (3.143 x 
x ) /
= 84.861
Hence area of sector is 84.861
If you round, it’ll be 7,0
Answer:
76.75 is 25% of 307
Step-by-step explanation:
Answer:
-0.0526
Step-by-step explanation:
Let X be the random variable denoting the net gain(in dollars) for a single trial(one bet).
Assuming that each number in the wheel is equally likely, probability of the outcome being a victory is 
and probability of failure is 
. For a win, X takes value 35 and for a loss X takes value -1. So the model is,
The mean for one bet is 
7, you divide the 14 by 2 because the qr is two times the length of gh, therefore 7 is two times the length of fh
