Establish for which constants c the following function is a density.

Valentin [98]

By "density" I assume you mean "probability density function". For this to be the case for $f(x)$ , we require

$\displaystyle\int_{-\infty}^\infty f(x)\,\mathrm dx=1$

Since

$f(x)=\begin{cases}cx^{1/2}&\text{for }0$

you have

$\displaystyle\int_{-\infty}^\infty f(x)\,\mathrm dx=\int_0^2cx^{1/2}\,\mathrm dx=\dfrac{2c}3x^{3/2}\bigg|_{x=0}^{x=2}=\dfrac{2^{5/2}c}3=1$

which means

$c=\dfrac3{2^{5/2}}=\dfrac3{4\sqrt2}$

Fred is running on the school track. He can run 10 3 4 laps in 4 5 of an hour. How many laps can Fred run in one hour?

Triss [41]

Answer:

$13\frac{7}{16}$ laps can Fred run in one hour.

Step-by-step explanation:

Given Statement: Fred is running on the school track. He can run $10\frac{3}{4}$ laps in $\frac{4}{5}$ of an hour.

Unit rate are expressed as a quantity of 1, such as 3 feet per second or 7 miles per hour, they are called unit rates

From the given condition we have;

In $\frac{4}{5}$ he can run $\frac{43}{4}$ laps

Unit rate per hour = $\frac{\frac{43}{4} }{\frac{4}{5} }$

= $\frac{43}{4} \times \frac{5}{4} = \frac{215}{16}$ laps

Therefore, Fred can run in one hour is, $13\frac{7}{16}$ laps.
