Answer:
option b is the correct i mean 10
Answer:
7/12
Step-by-step explanation:
-15/9+9/4
We need to make them have the same denominator:
9x4= 36 so that is our new denominator
-15x4= -60
9x9=81
(Sorry if i dont make sense)
Now we have -60/36+81/36 which is equal to 21/36.
Now we simplify:
21/36=7/12
Answer:
Carla is correct
Step-by-step explanation:
When you multiple or divide a negative the sign changes, or flips the other side.
ex:-4x≥12
-4x/-4≥12/-4
x≤-3
hope this helps!
Answer:
Step-by-step explanation:
The question says,
A roulette wheel has 38 slots, of which 18 are black, 18 are red,and 2 are green. When the wheel is spun, the ball is equally likely to come to rest in any of the slots. One of the simplest wagers chooses red or black. A bet of $1 on red returns $2 if the ball lands in a red slot. Otherwise, the player loses his dollar. When gamblers bet on red or black, the two green slots belong to the house. Because the probability of winning $2 is 18/38, the mean payoff from a $1 bet is twice 18/38, or 94.7 cents. Explain what the law of large numbers tells us about what will happen if a gambler makes very many betson red.
The law of large numbers tells us that as the gambler makes many bets, they will have an average payoff of which is equivalent to 0.947.
Therefore, if the gambler makes n bets of $1, and as the n grows/increase large, they will have only $0.947*n out of the original $n.
That is as n increases the gamblers will get $0.947 in n places
More generally, as the gambler makes a large number of bets on red, they will lose money.
