If you are driving 110km and hour, how far do you travel in 2 seconds

1 answer:

4 0

60 seconds in 1 minute.....60 minutes in one hr....60 * 60 = 3600 seconds/hr

110/3600 = x / 2......110 km in 3600 sec = x km in 2 sec
cross multiply because this is a proportion
(3600)(x) = (110)(2)
3600x = 220
x = 220/3600
x = 0.0611 km/hr <==

An insurance salesman sells on average 10.4 life insurance policies per week. Find the probability that in a particular week he

Fittoniya [83]

Answer:

$P(X=x) =\lambda^x \frac{e^{-\lambda}}{x!}, X= 0,1,2,...$

$P(X=8) = \frac{e^{-10.4} 10.4^8}{8!}= 0.1033$

And that would be the solution for this case.

Step-by-step explanation:

Previous concepts

The Poisson process is useful when we want to analyze the probability of ocurrence of an event in a time specified. The probability distribution for a random variable X following the Poisson distribution is given by:

$P(X=x) =\lambda^x \frac{e^{-\lambda}}{x!}, X= 0,1,2,...$

Solution to the problem

Let X the random variable that represent the number of life insurance policies that the salesman person sells. We know that $X \sim Poisson(\lambda=10.4)$

And we want to find this probability:

$P(X =8)$

And we can use the probability mass function and we got:

$P(X=8) = \frac{e^{-10.4} 10.4^8}{8!}= 0.1033$

And that would be the solution for this case.

AysviL [449]

Answer:

interest rate is 38.68 %

Step-by-step explanation:

Given data

installment = $60

time = 36 months = 36/12 = 3 years

principal = $1000

to find out

interest rate

Solution

we know student pay $60 for 36 months

so he pay total = 60 × 36 = 2160

total amount pay by student = $ 2160

so we can find interest rate by given formula

rate = (1/time)(amount/Principal - 1)

put the value time amount and principal here

rate = (1/3)(2160/1000 - 1)

rate = 0.386667

interest rate is 38.68 %
