Answer:

0.18203 = 18.203% probability that exactly four complaints will be received during the next eight hours.

Step-by-step explanation:

We have the mean during a time-period, which means that the Poisson distribution is used to solve this question.

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

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

In which

x is the number of sucesses

e = 2.71828 is the Euler number

[tex]\mu[/tex] is the mean in the given interval.

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

This means that [tex]\mu = 0.6h[/tex], in which h is the number of hours.

Determine the probability that exactly four complaints will be received during the next eight hours.

8 hours means that [tex]h = 8, \mu = 0.6(8) = 4.8[/tex].

The probability is P(X = 4).

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

[tex]P(X = 4) = \frac{e^{-4.8}*4.8^{4}}{(4)!} = 0.18203[/tex]

0.18203 = 18.203% probability that exactly four complaints will be received during the next eight hours.

Henry cut 1.5 m of the wire.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Henry cut 12.5% of the 12 m wire, which is:

= 0.125 x 12 m

= 1.5 m

Therefore,

Henry cut 1.5 m of the wire.

Answer:

The best measure of center for a set of data is the median value.

To find the median list the values from

Smallest to largest:

0, 0, 1, 1, 2,2, 2, 14

Since there is an even number of values, find the middle two numbers, add them together and divide by 2:

1+2 = 3

3/2 = 1.5

The answer is median 1.5

Answer:

  QT = 16

  VQ = 24

Step-by-step explanation:

The centroid divides each median into parts that have the ratio 1:2. The short length is the one from the centroid to the side (VT); the long length is the one from the centroid to the vertex (QT).

VT : QT = 1 : 2 = 8 : 16

VQ = VT +QT = 8 + 16 = 24

QT = 16

VQ = 24

Answer:

A= 30 sq feet

? = 5 feet

Step-by-step explanation:

if the total area is 104 square feet and we know where 44 square feet of that is accounted for that leaves 60 square feet so both A sections are equal so we can divide 60 by 2 to get 30 square feet. So "A" is 30 square feet.

to get "?" we need to find the other measurement for the 10 square foot sections, the easiest way to find that is 10 divided by 2 ( which is the measurement we already have), once we do this we get 5 feet, and because 5 feet is the height measurement for that part of the net diagram we know that the "?" will need to be 5 as well because it is also a height measurement.
