Historical data for a local manufacturing company show that the average number of defects per product produced is 2. In addition

charle [14.2K]

Answer:

The probability that there will be a total of 7 defects on four units is 0.14.

Step-by-step explanation:

A Poisson distribution describes the probability distribution of number of success in a specified time interval.

The probability distribution function for a Poisson distribution is:

$P(X = x)=\frac{e^{-\lambda}\lambda^{x}}{x!}, x=0,1,2,3,...$

Let <em>X</em> = number of defects in a unit produced.

It is provided that there are, on average, 2 defects per unit produced.

Then in 4 units the number of defects is, $(2\times4)=8$ .

Compute the probability of exactly 7 defects in 4 units as follows:

$P(X = x)=\frac{e^{-\lambda}\lambda^{x}}{x!}\\P(X=7)=\frac{e^{-8}8^{7}}{7!}\\=\frac{0.0003355\times2097152}{5040}\\ =0.1396\\\approx0.14$

Thus, the probability of exactly 7 defects in 4 units is 0.14.

What did a the surface area of the square pyramid below?

Mamont248 [21]

Answer:

Area of the square pyramid = $156\,cm^2$

Step-by-step explanation:

The Surface area of the square pyramid :

Area of the four triangular faces+ Area of the square base

$=(2\times Base \times Height )+ (Side\times Side)$

For triangle:

$Base=6\,cm\\Height=10\,cm$

Side of the square base= $6\,cm$

Area of the figure is:

$=(2\times 6 \times10 )+(6\times 6)\\\\=120+36\\\\=156\,cm^2$

The area of the square pyramid is : $156\,cm^2$
