I don't know so here's a meme, lol take a joke, it's 12am, I'm exhausted, and delaireus, and I need points.
Answer: y = 3x + 2
Step-by-step explanation:
we can start the equation as
y = 3x + b
To find b we plug in the points on the equation we already have
5 = 3(1) + b
5 = 3 + b
-3 -3
2 = b
Since b equals 2, the equation will be
y = 3x + 2
Answer:
x^2-x-12
Step-by-step explanation:
I used the box method its easier than foil method if that helps in the future
Answer:
Expected number of hours before the the group exits the building = E[Number of hours] = 3.2 hours
Step-by-step explanation:
Expected value, E(X) is given as
E(X) = Σ xᵢpᵢ
xᵢ = each variable
pᵢ = probability of each variable
Let X represent the number of hours before exiting the building taking each door. Note that D = Door
D | X | P(X)
1 | 3.0 | 0.2
2 | 3.5 | 0.1
3 | 5.0 | 0.2
4 | 2.5 | 0.5
E(X) = (3×0.2) + (3.5×0.1) + (5×0.2) + (2.5×0.5) = 3.2 hours
Hope this Helps!!!
