V=pi*r^2*h/3
=> h=3V/(pi*r^2)
V=6pi^2 cm^3
r=3 cm

h=3V/(pi*r^2)=6*pi^2 / (pi*3^2) = 2pi  cm

Height = 2 pi cm

KonstantinChe [14]

Answer:

The St. Louis Cardinals had the most total runs

The Texas Rangers had the most total hits

Step-by-step explanation:

From the given matrices, we have;

The total runs made by the St. Louis Cardinals is found by adding the runs obtained in each of the seven games as follows;

Total runs by St. Louis = 3 + 1 + 16 + 0 + 2 + 10 + 6 = 38

Similarly the total hits by the St. Louis Cardinals is given as follows;

Total hits by St. Louis = 6 + 6 + 15 + 2 + 7 + 13 + 7 = 56

For Texas Rangers, we have;

Total runs by Texas Rangers = 2 + 2 + 7 + 4 + 4 + 9 + 2 = 30

Total hits by the Texas Rangers = 6 + 5 + 13 + 6 + 9 + 15 + 6 = 60

Therefore, we have;

The St. Louis Cardinals has the most total runs with 38 runs which is more when compared to the Texas Rangers that have 30 runs

The Texas Rangers has the most total hits with 60 hits compared to the St. Louis Cardinals that have 56.

A service center receives an average of 0.6 customer complaints per hour. Management's goal is to receive fewer than five compla
Zolol [24]

Answer:

48.68% probability that managment is unhappy with the number of complaints in the next eight hours.

Step-by-step explanation:

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 time interval.

A service center receives an average of 0.6 customer complaints per hour.

This means that \mu = 0.6n, in which n is the number of hours.

Eight hours:

This means that n = 8, \mu = 0.6*8 = 4.8

Determine the probability that managment is unhappy with the number of complaints in the next eight hours.

They will be unhappy if they receive five or more complaints.

Either they receive less than five complaints, or they receive at least five. The sum of the probabilities of these events is 1. So

P(X < 5) + P(X \geq 5) = 1

We want P(X \geq 5).

Then

P(X \geq 1) = 1 - P(X < 5)

In which

P(X < 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)

So

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

P(X = 0) = \frac{e^{-4.6}*4.6^{0}}{(0)!} = 0.0101

P(X = 1) = \frac{e^{-4.6}*4.6^{1}}{(1)!} = 0.0462

P(X = 2) = \frac{e^{-4.6}*4.6^{2}}{(2)!} = 0.1063

P(X = 3) = \frac{e^{-4.6}*4.6^{3}}{(3)!} = 0.1631

P(X = 4) = \frac{e^{-4.6}*4.6^{4}}{(4)!} = 0.1875

P(X < 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) = 0.0101 + 0.0462 + 0.1063 + 0.1631 + 0.1875 = 0.5132

Finally

P(X \geq 1) = 1 - P(X < 5) = 1 - 0.5132 = 0.4868

48.68% probability that managment is unhappy with the number of complaints in the next eight hours.
