Please Help! What is the distance between points (2, 8) and (7, 5)? Round to the nearest tenth of a unit.

zavuch27 [327]

Distance formula is like pythagoren ahtoerem
D= $\sqrt{(7-2)^{2}+(5-8)^{2}}$
the distance between oints (x1,y1) and (x2,y2) is
D= $\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}$
(2,8) and (7,5)
D= $\sqrt{(7-2)^{2}+(5-8)^{2}}$
D= $\sqrt{(5)^{2}+(-3)^{2}}$
D= $\sqrt{25+9}$
D= $\sqrt{34}$
apxos
D=5.8309....

round
D=5.8 units

At a specific point on a highway, vehicles arrive according to a Poisson process. Vehicles are counted in 12 second intervals, a

morpeh [17]

Answer: a) 4.6798, and b) 19.8%.

Step-by-step explanation:

Since we have given that

P(n) = $\dfrac{15}{120}=0.125$

As we know the poisson process, we get that

$P(n)=\dfrac{(\lambda t)^n\times e^{-\lambda t}}{n!}\\\\P(n=0)=0.125=\dfrac{(\lambda \times 14)^0\times e^{-14\lambda}}{0!}\\\\0.125=e^{-14\lambda}\\\\\ln 0.125=-14\lambda\\\\-2.079=-14\lambda\\\\\lambda=\dfrac{2.079}{14}\\\\0.1485=\lambda$

So, for exactly one car would be

P(n=1) is given by

$=\dfrac{(0.1485\times 14)^1\times e^{-0.1485\times 14}}{1!}\\\\=0.2599$

Hence, our required probability is 0.2599.

a. Approximate the number of these intervals in which exactly one car arrives

Number of these intervals in which exactly one car arrives is given by

$0.2599\times 18=4.6798$

We will find the traffic flow q such that

$P(0)=e^{\frac{-qt}{3600}}\\\\0.125=e^{\frac{-18q}{3600}}\\\\0.125=e^{-0.005q}\\\\\ln 0.125=-0.005q\\\\-2.079=-0.005q\\\\q=\dfrac{-2.079}{-0.005}=415.88\ veh/hr$
