Consider a pole running from one corner to the farthest corner of a box. 
In 3D space the start of the pole would be at (0,0,0).
The endpoint would be at (12,2,1).
Use the distance formula:
D^2 = (x1-x2)^2 + (y1-y2)^2 + (z1-z2)^2
D^2 = (12-0)^2 + (2-0)^2 + (1-0)^2
D^2 = 144 + 4 + 1
D^2= 149
D = sqrt (149) 
D = (approx.) 12.21 ft
D = 12 ft

Have a nice day :D

What are the four arithmetic means between -10 and 35?
Nuetrik [128]

Answer:

-1, 8, 17, 26

Step-by-step explanation:

35 - (-10) = 45

45/5 = 9

-10 + 9 = -1

-1 + 9 = 8

8 + 9 = 17

17 + 9 = 26

Suppose the number of hits a webpage receives follows a Poisson distribution. The average number of hits per minute is 2.4. What
REY [17]

Answer:

The probability that the page will get at least one hit during any given minute is 0.9093.

Step-by-step explanation:

Let <em>X</em> = number of hits a web page receives per minute.

The random variable <em>X</em> follows a Poisson distribution with parameter,

<em>λ</em> = 2.4.

The probability function of a Poisson distribution is:

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

Compute the probability that the page will get at least one hit during any given minute as follows:

P (X ≥ 1) = 1 - P (X < 1)

             = 1 - P (X = 0)

             =1-\frac{e^{-2.4}(2.4)^{0}}{0!}\\=1-\frac{0.09072\times1}{1} \\=1-0.09072\\=0.90928\\\approx0.9093

Thus, the probability that the page will get at least one hit during any given minute is 0.9093.

6. A store orders 8 boxes of notebooks.
Tamiku [17]

Answer: 1,152 notebooks

Step-by-step explanation:

You just do 144 x 8. I’m not really sure what they mean when they say use breaking apart method. Maybe break them up into 8 group of 144. Then just add 144 together 8 times instead of multiplying hope this helps. :)
