Answer:
Step-by-step explanation:
The exponential distribution is "the probability distribution of the time between events in a Poisson process (a process in which events occur continuously and independently at a constant average rate). It is a particular case of the gamma distribution". The probability density function is given by:
And 0 for other case. Let X the random variable that represent "The number of years a radio functions" and we know that the distribution is given by:
We can assume that the random variable t represent the number of years that the radio is already here. So the interest is find this probability:
We have an important property on the exponential distribution called "Memoryless" property and says this:
Where a represent a shift and t the time of interest.
On this case then
We can use the definition of the density function and find this probability:
The slope is the change in Y over the change in X.
Change in Y = y2 - y1 = 1 - (-5) = 1+5 = 6
Change in X = x2 - x1 = 4 - 1 = 3
Slope = 6 /3 which simplifies to 2.
m = 2
Just remember that irrationals have to do with decimals; while rational numbers have to do with being completely whole numbers.
a) The value of as a function of "x" is
b) The rate of change of the angle with respect to x is -0.000308rad/m
Find the complete question and diagram attached
Form the right-angled triangle shown:
Adjacent side = x
Opposite side = 250m
angle of elevation =
Using the SOH CAH TOA identity
Hence the value of as a function of "x" is
b) If x = 450m
Differentiate both sides with respect to "x"
Substitute x = 450m and into the resulting expression to have:
Hence the rate of change of the angle with respect to x is -0.000308rad/m
