Wayne Gretsky scored a Poisson mean six number of points per game. sixty percent of these were goals and forty percent were assi
BartSMP [9]

Answer:

a) The mean for the total revenue he earns per game is of 13.2K while the standard deviation is of 3.63K.

b) 0.05 = 5% probability that he has four goals and two assists in one game

Step-by-step explanation:

In hockey, a point is counted for each goal or assist of the player.

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

In which

x is the number of sucesses

e = 2.71828 is the Euler number

\mu is the mean in the given interval. The standard deviation is the square root of the mean.

(a) Find the mean and standard deviation for the total revenue he earns per game.

60% of six are goals, which means that 60% of the time he earned 3K.

40% of six are goals, which means that 40% of the time he earned 1K.

The mean is:

\mu = 6*0.6*3 + 6*0.4*1 = 13.2

The standard deviation is:

\sigma = \sqrt{\mu} = \sqrt{13.2} = 3.63

The mean for the total revenue he earns per game is of 13.2K while the standard deviation is of 3.63K.

(b) What is the probability that he has four goals and two assists in one game

Goals and assists are independent of each other, which means that we find the probability P(A) of scoring four goals, the probability P(B) of getting two assists, and multiply them.

Probability of four goals:

60% of 6 are goals, which means that:

\mu = 6*0.6 = 3.6

The probability of scoring four goals is:

P(A) = P(X = 4) = \frac{e^{-3.6}*(3.6)^{4}}{(4)!} = 0.19122

Probability of two assists:

40% of 2 are assists, which means that:

\mu = 6*0.4 = 2.4

The probability of getting two assists is:

P(B) = P(X = 2) = \frac{e^{-2.4}*(2.4)^{2}}{(2)!} = 0.26127

Probability of four goals and two assists:

P(A \cap B) = P(A)*P(B) = 0.19122*0.26127 = 0.05

0.05 = 5% probability that he has four goals and two assists in one game

Geometric mean <br> Pls help thank u
quester [9]

Answer:

Step-by-step explanation:

1). Geometric mean of a and b = \sqrt{a\times b}

   Therefore, geometric mean of 2 and 50 = \sqrt{2\times 50}

                                                                       = 10

2). By geometric mean theorem,

   \frac{JM}{KM}=\frac{KM}{ML}

   \frac{6}{e}=\frac{e}{24}

   e² = 6 × 24

   e = √144

   e = 12

  Similarly, \frac{JL}{KJ}=\frac{KJ}{JM}

   \frac{6+24}{d}=\frac{d}{6}

   d² = 6 × 30

   d = √180

   d = 6√5

   And \frac{JL}{KL}=\frac{KL}{ML}

   \frac{6+24}{c}=\frac{c}{24}

   c² = 30 × 24

   c = √720

   c = 12√5

The perimeter of the triangle below is 97 cm.
Sloan [31]

Answer:

The length of EF = x = 18 cm

Option A is correct.

Step-by-step explanation:

Ware given perimeter of triangle = 97 cm

We need to find length of EF = x = ?

The length of EG = x+7

The length of EF = x

The length of GF = 3x

The formula used is: Periemter \ of \ triangle= Sum \ of \ all \ sides \ of \ triangle

Putting values and finding x i.e length of EF

Periemter \ of \ triangle= Sum \ of \ all \ sides \ of \ triangle\\97=x+7+x+3x\\97-7=5x\\5x=90\\x=\frac{90}{5}\\x=18 \ cm

So, value of x=18 cm

The length of EF = x = 18 cm

Option A is correct.
