Answer:

120

Step-by-step explanation:

First subtract 3/5 and 2/5, which gives you 1/5 or 0.2.

Next, divide 6 by 0.2 or 1.5, giving you 30.

Multiply 30 by 4, which gives you 120.

Suppose rain is falling at an average rate of 30 drops per square inch per minute. What is the chance that a particular square i

borishaifa [10]

Answer:

Therefore the chance that a particular square inch is not by any drops during a given 10 second period is $e^{-5a}$ .

Step-by-step explanation:

Poisson distribution:

$P(X=x)= \frac{e^{-\lambda t} (\lambda t)^x}{x!}$

Given that rain is falling at an average rate 30 drops per square inches per minutes.

A reasonable choose of this distribution is Poisson distribution $(\lambda t)$ .

Let the area be a square inch.

Here $\lambda$ = average rate of rain drop × area

=(30×a)= 30 a

t = 10 second $= \frac{10}{60} \ minutes$ $=\frac16\ minutes$ .

Therefore,

$P(\textrm {no rain drop in }\frac16 \ minutes) =P(X=0)$

$=\frac{e^{-\frac{30a}{6}}.(\frac{30a}{6})^0}{0!}$

$=e^{-5a}$

Therefore the chance that a particular square inch is not by any drops during a given 10 second period is $e^{-5a}$ .

For the function f defined b f(x)=x^2+2x+3 find f(-x), -f(x), and -f(-x).

Rom4ik [11]

Answer:

see explanation

Step-by-step explanation:

To evaluate f(- x) substitute x = - x into f(x)

f(- x) = (- x)² + 2(- x) + 3 = x² - 2x + 3

-----------------------------------------------------

- f(x) = - (x² + 2x + 3) ← distribute parenthesis by - 1

= - x² - 2x - 3

-----------------------------------------------------------

- f(- x) ← substitute f(- x) from above

= - (x² - 2x + 3) ← distribute parenthesis by - 1

= - x² + 2x - 3
