Answer:
Of the 777 rounds of the game in about 368 the ball will land in a red slot.
Step-by-step explanation:
Since a roulette wheel has 383838 slots, of which 181818 are red, 181818 are black, and 222 are green, and in each round of the game, a ball is tossed in the spinning wheel and lands in a random slot, supposing we watch 777 rounds of this game, to determine the approximate number of rounds where the ball lands in a red slot, the following calculation must be performed:
383838 = 100
181818 = X
181818 x 100/383838 = X
18,181,800 / 383838 = X
47.3684 = X
100 = 777
47.3684 = X
47.3684 x 777/100 = X
36,805.24 / 100 = X
368.05 = X
Therefore, of the 777 rounds of the game in about 368 the ball will land in a red slot.
Finish the equation given for x:
10x +15 = 9(9)
= 10x +15 = 81
Subtract 15 from both sides:
10x = 66
Divide both sides by 10:
x = 66/10
X = 6.6
Now replace x with 6.6 in the equation for DE:
DE = 2(6.6) +3
Simplify:
DE = 13.2 + 3
DE = 16.2
