<h3>
Answer:  13/28</h3>
========================================================
Reason:
The table shows he got 26 heads out of 26+30 = 56 coin flips.
26/56 = (2*13)/(2*28) = 13/28 is the empirical or experimetnal probablity of getting heads. 
Side note: 13/28 = 0.4643 = 46.43% approximately which is fairly close to 50%
 
        
             
        
        
        
Answer:
Step-by-step explanation:
The applicable formula is ...
   s = rθ
where s is the arc length, r is the circle's radius, and θ is the central angle in radians.
Filling in the given values, we find ...
   15 = 6θ
   θ = 15/6 = 2.5 . . . radians
Pi (π) radians is 180°, so the angle in degrees is ...
   2.5(180°/π) ≈ 143.24°
 
        
             
        
        
        
Given:
The expression is:

To find:
The value of the given expression when 
.
Solution:
We have,

Substituting 
 in the above expression, we get




Therefore, the value of given expression at 
 is 59.
