Suppose that, after measuring the duration of many telephone calls, a telephone company found their data was well-approximated by the density function p(x)=0.8−0.8x, where x is the duration of a call, in minutes. (a) What percentage of calls last between 1 and 2 minutes? Percent = 100(-e^(-1.6) + e^(-0.8)) percent (b) What percentage of calls last 1 minutes or less? Percent = 100(1-e^(-0.8)) percent (c) What percentage of calls last 4 minutes or more? Percent = 100(e^(-3.2)) percent (d) What is the cumulative distribution function, P()?

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )

the answer is: the length is 5/6 yards.

give me a or a 5 star rating if this is correct!

step-by-step explanation:

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
