1 cup of cool water (in a glass tumbler) took about 3 hours to freeze in my freezer.
Answer:
D is the correct option
Step-by-step explanation:
The roulette can land in any possibly slot and their are 38slots
i.e the total possible event is 38
Green slot = 2
Red slot =18
Black slot =18
P(G)=2/38 =1/19
P(R)=18/38=9/19
P(B)=18/38=9/19.
The roulette will be spun twice and they are independent i.e. the occurrence of one event does not affect the occurrence of the other.
We are looking for the probability of red first and probability of black
P(R n B)=P(R)P(B), since they are independent
P(R n B)=9/19×9/19
P(R n B)= 0.2244
D is the correct option
Answer:
steps below
Step-by-step explanation:
f(x) = 5x³ - x² - 5x + 1
Local extremes: 15x²-2x-5=0 .. gradient=0
x = (2 ± √2²-4*(15)*(-5)) / (2*15)
= (2 ± √304) / 30
= (2 ± 4√19) / 30
= (1 ± 2√19) / 15
= (1 ± 8.718) / 15
local maximum: (1 + 8.718) / 15 = 0.648
local minimum: (1 - 8.718) / 15 = - 0.515
the interval(s) where the graph is increasing: x < - 0.515 or x > 0.648
the interval(s) where the graph is decreasing: - 0.515 < x < 0.648
