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
I don't get it, answer what???

Step-by-step explanation:
Where the line crosses the x- axis the y- coordinate is zero.
Substitute y = 0 into the equation and solve for x
x + 2 = 0 ( multiply through by 4 to clear the fraction )
x + 8 = 0 ( subtract 8 from both sides )
x = - 8 ← x- intercept ⇒ (- 8, 0 )
Where the line crosses the y- axis the x- coordinate is zero.
Substitute x = 0 into the equation and solve for y
y = 0 + 2, that is
y = 2 ← y- intercept ⇒ (0, 2 )

<em>Answer:</em>
<em>Not likely</em>
<em>Step-by-step explanation:</em>
<em>0.0 -- 0.32 = Not likely</em>
<em>0.33 -- 0.66 = Neither likely or unlikely</em>
<em>0.67 -- 1.0 = Likely</em>
