A circle has a radius of 3 An arc in this circle has a central angle of 20 what is the length of the arc
 
        
             
        
        
        
F(x)= -x + 1
You can also use y instead of the f(x) notation. 
I got this bc 1 is the y intercept. I know this because when x=0, the y value of that point is the y intercept. 
To get slope I chose two values and did y2-y1/x2-x1

Answer:
P(marks ≥ 20) = 0.4
Step-by-step explanation:
Marks gotten by the 5 students are;
15, 14, 20, 17, 25
Marks more than or equal to 20 are 2 in number namely 20 and 25.
Thus, probability of getting marks more than or equal to 20 is;
P(marks ≥ 20) = 2/5
P(marks ≥ 20) = 0.4
