Answer:
Step-by-step explanation:
3 coins make for 8 possible outcomes {HHH,HHT,HTH,THH,HTT,THT,TTH,TTT}
4 Possible outcomes conatin 2 or more heads.
Probability (At least 2 Heads) = Favourable outcomes/Total possible outcomes
                                                = 4/8 = 1/2 = 0.5 (50%)
 
        
                    
             
        
        
        
7.4 is your final answer, hope that help, one decimal place is the first number after the decimal.
        
             
        
        
        
Answer:
   1.2 minutes
Step-by-step explanation:
The applicable relationship between speed, distance, and time is ...
   time = distance/speed
   = (3 km)/(150 km/h) = (3/150) h = 1/50 h 
   = (60 min)/50 = 1.2 minutes

<span>No, it doesn't. To find out if it's a right angled triangle, we use Pythagorean triple. It states that the square of the hypotenuse (the longest side) is equal to the sum of the squares of the opposite and adjacent sides. Obviously, the longest side, which is our hypotenuse is 24. So we want to find out whether the square of our hypotenuse is equal to the sum of the squares of the other two sides i. e 13 and 21.
24^ 2 = 576 ; 13^2 = 169 ; 21^2 = 441;
So is 576 = 169 + 441. An emphatic No: hence the triangle isn't right angled since it doesn't satisfy pythagorean triple.. A^2 is not equal to B^2 + C^2 where a is the hypotenuse and b and c the opposite and adjacent sides.</span>
