There might just be 1. try multiplying percentage by the number of people

Empirical formula

0.33

0.33

A^c = event B or event C

Step-by-step explanation:

A = roommate A wins the game

P(A) = (Rock A and Scissors B) + (Scissors A and paper B) + (paper A and rock B)

P(A) = (0.36*0.53) + (0.32*0.25) + (0.32*0.22) = 0.3412

C = game ends in a tie :

P(C) = (RockA and rockB) + (ScissorsA and ScissorsB) + (ScissorsA and ScissorsB)

P(C) = (0.36*0.22) + (0.32*0.53) + (0.32*0.25) = 0.3288

P(B) = 1 - P(A) - P(C)

P(B) = 1 - 0.3412 - 0.3288

P(B) = 0.33

Complement of event A =event B or event C

A port and a radar station are 3 mi apart on a straight shore running east and west. A ship leaves the port at noon traveling at

Brums [2.3K]

Answer:

The answer is $34.37 deg/h$ .

Step-by-step explanation:

Use the image provided here for clarification purposes. It helps so much to make a drawing in this sort of questions. The tracking angle here is drawn as $\theta$ .

<em>Law of sines </em>is applied to the vertical side (ship's trayectory) and the horizontal side (shore line). Here, time must be expressed in hours:

$\frac{sin \theta}{18t}=\frac{sin(\pi /2 - \theta)}{3}=\frac{cos\theta}{3}$

$tan(\theta)=\frac{18t}{3} = 6t$ .

$\theta=arctan(6t)$ .

So, the rate of change of our tracking angle, $\theta$ , can be obtained by deriving this expression:

$\frac{d \theta}{dt}=6\frac{1}{1+(6t)^2}$ .

At 12:30 PM, i.e., half an hour after departure, t = 1/2, so:

$\frac{d \theta}{dt}(t=1/2)=6\frac{1}{1+(3)^2}=6/10=0.6$ rads/h.

Please note this is the actual rate of change of the tracking angle at this very moment, but not for the rest of moments. It is a function, variable with time, applied to a specific instant. For a value in degrees,

$0.6\frac{180deg}{\pi}=34.37 deg/h$
