oksian1 [2.3K]

Answer: C. the base period amount.

Explanation: While implementing a horizontal analysis on a given income statement, we compute a percentage change in any individual item by dividing the dollar amount of change from base to current time period with the base period amount.

i.e. % Change in Individual item = $\frac{Current\ Dollar\ - Base\ Dollar }{Base \ period \ amount}$

Therefore, the correct option in this case is (c)

The waiting time, in hours, between successive speeders spotted by a radar unit is a continuous random variable with cumulative

snow_lady [41]

Given the CDF

$F_X(x)=\begin{cases}0&\text{for }x$

we have PDF

$\dfrac{\mathrm dF_X(x)}{\mathrm dx}=f_X(x)=\begin{cases}0&\text{for }x$

Note that $X$ is wait-time given in hours, so we need to convert from minutes to hours:

$12\text{ min}\times\dfrac{1\text{ hr}}{60\text{ min}}=\dfrac15\text{ hr}$

so we're looking for $\mathbb P\left(X$ .

The CDF gives us this value right away, since $F_X(x)=\mathbb P(X$ for any continuous random variable $X$ with distribution function $F_X(x)$ :

$\mathbb P\left(X$

To use the PDF, we need to integrate:

$\mathbb P\left(X$
