Answer:4
Step-by-step explanation:
64 divided by 16 is 4.y-step explanation
Answer: or (1,1)
Step-by-step explanation:
You can apply the Method of substitution.
Knowing that (second equation), you can substitute it into the first equation and solve for the variable y:
Now you need to substitute into the second equation to calculate the value of the variable x. Then:
Then, the solution is:
or (1,1)
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
