The 4th option is correct
        
             
        
        
        
Step-by-step explanation:
For 4.
4b + 2b + 3b = 180°< Sum of angles of triangle >
9b = 180°
b = 180° / 9
b = 20°
4b = 4* 20° = 80°
2b = 2* 20° = 40°
3b = 3 * 20° = 60°
For 5.
x = 64° + 45° <Exterior angle of a triangle is equal to the sum of two opposite interior angles>
x = 109°

6 sides on a dice 1-6 numbers probability is 4/6 or 2/3
        
             
        
        
        
26 would be the correct answer because 2/3 X 40 = 26.667 but you cant serve a little bit of soup so the total would be 26   Hoped this helped
        
                    
             
        
        
        
5, 5, 9, 12, 18, 22, 25 put numbers in order least to greatest
25 -5 = 20 that is the range
12 is the middle number this is the median
5 is the mode, it is the number that is repeated the most
