Answer:

The four pieces cut off can be arranged into two squares with sides of length b feet and hence the area of the octagon is w 2 - 2 b 2 square feet. Since w = 12 feet, all that is needed is to find b. square feet which is approximately 119 square feet.

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

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 is the distance between (0, -2) and (9, 10) ? please show your work so i can understand thank you

Setler [38]

Given:

The two points are (0, -2) and (9, 10).

To find:

The distance between the given points.

Solution:

Distance between the two points is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Using the above distance formula, the distance between given points is

$d=\sqrt{(9-0)^2+(10-(-2))^2}$

$d=\sqrt{(9)^2+(10+2)^2}$

$d=\sqrt{81+(12)^2}$

On further simplification, we get

$d=\sqrt{81+144}$

$d=\sqrt{225}$

$d=15$

Therefore, the distance between the given points (0,-2) and (9,10) is 15 units.
