You have set up a webpage for your company. your logo took up 2/7 of your allotted space on the main page and the location infor
Maksim231197 [3]
So we want to find how much more space the logo took up.

So just subtract the location info from the logo space.

2/7 - 1/10

To subtract, you just want to find a common denominator. In this case it would be 70.

2/7 * 10/10 - 1/10 * 7/7

20/70 - 7/70

Then just subtract.

13/70

So that's the fraction. For the percent, just divide.

13/70 = 0.186 ish

Or, 18.6% ish

The number of Apple iPods sold in 2009 was 54.13 million. That number decreased approximately linearly to 26.38 million iPods so
AleksandrR [38]

Answer:

A(t) = -6.9375t + 81.88 is the amount, in millions, for the number of Apple iPods sold in t years after 2005.

Step-by-step explanation:

Linear function:

A linear function has the following function:

y = mx + b

In which m is the slope(the value that y changes by when x changes by 1) and b is the y-intercept(the initial value of the output).

Finding the value in 2005:

This is b.

The number of Apple iPods sold in 2009 was 54.13 million. That number decreased approximately linearly to 26.38 million iPods sold in 2013.

So in 4 years, it decreased from 54.13 - 26.38 = 27.75 million.

So the value in 2005 should also be 27.75 million more than in 2009, that is 54.13 + 27.75 = 81.88. So

y = mx + 81.88

Using A for y and t for x

A(t) = mt + 81.88

Finding the slope:

When we have two points, the slope is given by the change in the output divided by the change in the input.

In 4 years, the amount decrease by 27.75 million. So

m = -\frac{27.75}{4} = -6.9375

So

A(t) = -6.9375t + 81.88 is the amount, in millions, for the number of Apple iPods sold in t years after 2005.

A disadvantage of the contention approach for LANs, such as CSMA/CD, is the capacity wasted due to multiple stations attempting
sammy [17]

Answer:

The overview of the given problem is outlined in the following segment on the explanation.

Step-by-step explanation:

The proportion of slots or positions that have been missed due to numerous concurrent transmission incidents can be estimated as follows:

Checking a probability of transmitting becomes "p".

After considering two or even more attempts, we get

Slot fraction wasted,

= [1-no \ attempt \ probability-first \ attempt \ probability-second \ attempt \ probability+...]

On putting the values, we get

= 1-no \ attempt \ probability-[N\times P\times probability \ of \ attempts]

= 1-(1-P)^{N}-N[P(1-P)^{N}]

So that the above seems to be the right answer.
