Number of ones = 60
Number of twos = 62
Number of threes = 59
Number of fours = 64
Number of fives = 63
Number of sixes = 75

Total even outcomes = total number of two, four and sixes = 62 + 64 + 75 = 201

Total outcomes = 60+62+59+64+63+75= 383

Probability if rolling an even number = 201/383

percentage= 201/383 × 100 = 52.48% ~ 52.5%

A ball is thrown from a height of 49 meters with an initial downward velocity of 2 m/s. The ball's height (in meters) after t se
horsena [70]

The height of the ball at ground level would be 0 feet.

Set h to 0 and solve for t:

Rewrite the equation as  

-5t^2 -2t +49 = 0

Factor -1 out of the equation to get:

5t^2 + 2t -49 = 0

Use the quadratic formula:

-b +/- sqrt(b^2 -4(ac) / 2a

Where a = 5, b = 2 and c = -49

The quadratic formula becomes:

-2 +/-sqrt(2^2 – 4(5*-49) / (2*5)

Simplify to get :

T = -2 +/-sqrt246 / 10

T = 2.936 and – 3.336

Since the time has to be a positive value t = 2.936 seconds.

Rounded to the nearest hundredth = 2.94 seconds.
