Problem 8-12 The time between accidents at a congested intersectionhas an exponential distribution with unknown parameter , which mayassume values of (1) 1/hour, (2) 3/hour, or (3) 5/hour. Completethe following for each of these levels.

(a) Determine the probability that an accident will happen within1.5 hours.

a. lambda=1/hour probability=
b. lambda=3/hour probability=
c. lambda=5/hour probability=

(b) Find the expected time between accidents.

a. lambda=1/hour expectation=
b. lambda=3/hour expectation=
c. lambda=5/hour expectation=

(c) Find the variance in time between accidents.

a. lambda=1/hour variance=
b. lambda=3/hour variance=
c. lambda=5/hour variance=

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

345

step-by-step explanation:

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
