Answer:
49 is equal to 7 times 7
Explanation:
A "perfect square" is a number that is the product of a whole number that is multiplied by itself.
In the example above, 49 is a perfect square because <em>it is the product of the square of 7</em>. If you multiply 7 by itself, the product is 49.
Other examples of perfect squares are:
25 = <em>25 is equal to 5 x 5</em>
100 = <em>100 is equal to 10 x 10</em>
81 = <em>81 is equal to 9 x 9</em>
16 = <em>16 is equal to 4 x 4</em>
64 = <em>64 is equal to 8 x 8</em>

Explanation:
Previous concepts
The cumulative distribution function (CDF) F(x),"describes the probability that a random variableX with a given probability distribution will be found at a value less than or equal to x".
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".
Part a
Let X the random variable of interest. We know on this case that
And we know the probability denisty function for x given by:
In order to find the cdf we need to do the following integral:
Part b
Assuming that , then the density function is given by:
And for this case we want this probability:
And evaluating the integral we got:
