Answer:
Step-by-step explanation:
h(x) = 7 - x - 2x^5
h(-1) = 7 + 1 - 2(-1)^5
h(-1) = 7 + 1 + 2
h(-1) = 10
Now differentiate h(x)
h'(x) = -1 - 2*5*x^4
h'(x) = -1 - 10x^4
h'(x) = -1 - 10(x)^4
h'(x) = -1 - 10 (x)^4
h'(-1) = -1 - 10(10000)
h'(-1) = -1 - 100000
h'(-1) = - 99999
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.
