SEND HELP YO Find and simplify the area (You need to completely multiply it out and include units in your answer):

Ad libitum [116K]

Answer:

$Area = 2m^8 - 6m^4 + 4.5$

Step-by-step explanation:

Given

$Base = 2m^4 - 3$

$Height = 2m^4 - 3$

Required

The area

This is calculated as:

$Area = 0.5 * Base * Height$

$Area = 0.5 * (2m^4 - 3) * (2m^4 - 3)$

Open brackst

$Area = 0.5 * (4m^8 - 6m^4 - 6m^4 + 9)$

$Area = 0.5 * (4m^8 - 12m^4 + 9)$

Open bracket

$Area = 2m^8 - 6m^4 + 4.5$

The number of typing errors made by a typist has a Poisson distribution with an average of three errors per page. If more than t

damaskus [11]

Answer:

0.6472 = 64.72% probability that a randomly selected page does not need to be retyped.

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 interval.

Poisson distribution with an average of three errors per page

This means that $\mu = 3$

What is the probability that a randomly selected page does not need to be retyped?

Probability of at most 3 errors, so:

$P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)$

In which

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

$P(X = 0) = \frac{e^{-3}*3^{0}}{(0)!} = 0.0498$

$P(X = 1) = \frac{e^{-3}*3^{1}}{(1)!} = 0.1494$

$P(X = 2) = \frac{e^{-3}*3^{2}}{(2)!} = 0.2240$

$P(X = 3) = \frac{e^{-3}*3^{3}}{(3)!} = 0.2240$

Then

$P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.0498 + 0.1494 + 0.2240 + 0.2240 = 0.6472$

0.6472 = 64.72% probability that a randomly selected page does not need to be retyped.
