The number of accidents that occur at a busy intersection is Poisson distributed with a mean of 4.5 per week. Find the probabili
Mariana [72]

Answer:

a) 0.01111

b) 0.4679

c) 0.33747

Step-by-step explanation:

We are given the following in the question:

The number of accidents per week can be treated as a Poisson distribution.

Mean number of accidents per week = 4.5

\lambda= 4.5

Formula:

P(X =k) = \displaystyle\frac{\lambda^k e^{-\lambda}}{k!}\\\\ \lambda \text{ is the mean of the distribution}

a) No accidents occur in one week.

P(x =0)\\\\= \displaystyle\frac{4.5^0 e^{-4.5}}{0!}= 0.01111

b) 5 or more accidents occur in a week.

P( x \geq 5) = 1-\displaystyle \sum P(x

c) One accident occurs today.

The mean number of accidents per day is given by

\lambda = \dfrac{4.5}{7} = 0.64

P(x =1)\\\\= \displaystyle\frac{0.64^1 e^{-0.64}}{1!}= 0.33747

An angle measures 29.2° less than the measure of its supplementary angle. What is the measure of each angle?
kiruha [24]

Answer:

104.6 deg, 75.4 deg

Step-by-step explanation:

One angle measures x.

The other angle measures 29.2 deg less than x, so it measures x - 29.2.

They are supplementary angles, so the sum of their measures is 180 deg.

x + x - 29.2 = 180

2x - 29.2 = 180

2x = 209.2

x = 104.6

x - 29.2 = 75.4

Answer: 104.6 deg, 75.4 deg
