Five distinct numbers are randomly distributed to players numbers 1 through 5. Whenever two playerscompare their numbers, the on

ad-work [718]

Answer:

Observe that the first and the second player have equal probability to get any of number. Using the principle of that symmetry, we have that

$P(X=0)=\frac{1}{2}$

Event X = 1 means that the first player has got greater number than the second player, but not than the third player. So, choose any three numbers out of five of them and say that the minimal number out of these three goes to the second player, mean number to the first one and the largest to the third one. Permute remaining two numbers on remaining two people. Hence

$P(X=1)=\frac{1}{6}$

Event X = 2 means that the first player has got greater number than the second and the third player, but not than the fourth player. So, choose any four numbers out of five of them and say that the minimal number and the next minimal out of these four go to the second and the third player (and permute them), third number to the first one and the largest to the fourth player. Give remaining number to the last person. Hence

$P(X=2)=\frac{1}{12}$

Event X = 3 means that the first player has got greater number than the second, the third, and the forth player, but not than the fifth player. So, permute these five numbers as follows: give the highest to the last person, the second highest to the first, and permute remaining numbers on the remaining people. Hence

$P(X=3)=\frac{1}{20}$

Event X = 4 means basically the first player has won all the battles i.e, he has got the greatest number. Hence

$P(X=4)=\frac{1}{5}$

Choose the equation that models the following statement: The current, I amps, produced by a battery is inversely proportional to

Anika [276]

By definition we have to:
V = I * R
Where,
V: Voltage.
I: Current.
R: Resistance.
The current, I amps, produced by a battery is inversely proportional to the resistance, R ohms. Clearing I have:
I = V / R
rewriting:
I = V * (1 / R)
answer:
The equation that models the statement is:
I = V * (1 / R)

Find the exact area of a circle with a dimeter of 5 yards. Use 3.14 for pi

kenny6666 [7]

Answer:

$A = 6.25(pi)$

$A$ ~ $19.63495$

Step-by-step explanation:

The formula for finding the area of a circle is;

$A = (pi)r^2$

Where ( $A$ ) represents the area of the circle, ( $pi$ ) represents the value ( $3.1415...$ ) and ( $r$ ) represents the radius of the circle. As per its definition, the diameter is the largest cord or line segment that can be drawn through a circle, the diameter always passes through the center of a circle. The radius ( a line segment that can be drawn from the center of the circle to any side of the circle) is always half of the diameter.

This means that the radius for the given circle is ( $2.5$ ), since ( $5$ ÷ $2=2.5$ )

Substitute these values into the equation and solve for the area of the circle.

$A = (pi)r^2\\\\A = (pi)(2.5)^2\\\\A = (pi)6.25\\$

$A$ ~ $19.63495$
