Answer:
P(2)=0.256
Step-by-step explanation:
We know that Nancy has noticed that 20 trucks pass by her apartment daily (24 hours). We conclude that for 1 hours, pass 20/24=5/6 trucks.
We calculate how many trucks pass for 3 hours:
3 · 5/6= 15/6=2.5=λ
We use a Poisson distribution:
P(k)=\frac{λ^k · e^{-λ}}{k!}
For 2 trucks we have that is k=2. We know that is λ=2.5
We caclulate the probability
P(2)=\frac{2.5² · e^{-2.5}}{2!}
P(2)=0.256
If you divide the 2 in 3 you get .6 and if you divide 2 in 5 ou get ,4 now add them you and get 1 now add that 1 to 30 your answer should be 31
P is True (x+x does indeed = 2x)
q is False ((3x)(-2y)=-6xy)
pVq is True (TvF is True)
p->q is False (p->q) equiv ~(p^~q) equiv ~(T^~F) equiv ~(T^T) = F
p^~q is True ((T^~F) = T^T = T)
p->~q is True (T->~F)
We can find the slope from (y2-y1)/(x2-x1) . So (-3-6)/(6+2) = -9/8
