Answer:
Probability, P(X=3)=0.05371
Step-by-step explanation:
The experiment consists of 12 Bernoulli trials,n=12
Where sucess is defined with difference between the speakers and failure is defined with no difference between the speakers
Since people are guessing,the Probability P of sucess= 1/2
Therefore P(X=3) = b(3; 12, 0.5) = (12/3) (0.5)^3× (0.5)^9
P( X=3) = 0.0537
Answer:
x = 0, y = 2
Step-by-step explanation:
Substitute the first equation into the second equation so 3x + 3(x+2) = 6. Simplify this to get x = 0. Plug x = 0 back into the first equation to get y = 2.

Answer:
Hyperbola
Step-by-step explanation:
Lets write variables in square form using completing the square method
LEts group x and y terms
y^2 terms should be positive always, so we pull out negative sign from y^2
We have negative sign in the middle. so we will get equation in the form of
If we have negative sign in the middle then it is an hyperbola
