Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.

andriy [413]

Binary values are used to denote the 'ON' and 'OFF' state of a computer. The 'ON' state is denoted by the binary value '1'

The 'ON' state of a computer represents the mode when the computer system is running and can be used to perform computing operations.

The binary values '0' and '1' are used to designate the ON and OFF state.

When the computer is ON, it is designated by the binary value 1 ; while the OFF state is designated by the binary value 0.

Therefore, the number which signifies the ON state of a computer is 1.

By changing the field size for text to the maximum number necessary,

Inessa05 [86]

Answer:

The correct option is;

A. The file will not take up as much space on the database

Explanation:

Changing the field size of a field that does not contain data limits the size of taken up by the data values added to the field. The field size for text field determines the disc space that each value of the field allowed to take up by Access

When the field size is changed for fields containing data, the data values in the field that have values higher than the maximum field size are truncated while the field size of subsequent data are limited as stated above.

Oxnard Casualty wants to ensure that their e-mail server has 99.98 percent reliability. They will use several independent server

sattari [20]

Answer:

The smallest number of servers required is 3 servers

<em />

Explanation:

Given

$Reliability = 99.98\%$

$Individual Servers = 95\%$

Required

Minimum number of servers needed

Let p represent the probability that a server is reliable and the probability that it wont be reliable be represented with q

Such that

$p = 95\%\\$

It should be noted that probabilities always add up to 1;

So,

$p + q = 1$ '

Subtract p from both sides

$p - p + q = 1 - p$

$q = 1 - p$

Substitute $p = 95\%\\$

$q = 1 - 95\%$

Convert % to fraction

$q = 1 - \frac{95}{100}$

Convert fraction to decimal

$q = 1 - 0.95$

$q = 0.05$

------------------------------------------------------------------------------------------------

<em>To get an expression for one server</em>

The probabilities of 1 servers having 99.98% reliability is as follows;

$p = 99.98\%$

Recall that probabilities always add up to 1;

So,

$p + q = 1$

Subtract q from both sides

$p + q - q = 1 - q$

$p = 1 - q$

So,

$p = 1 - q = 99.98\%$

$1 - q = 99.98\%$

Let the number of servers be represented with n

The above expression becomes

$1 - q^n = 99.98\%$

Convert percent to fraction

$1 - q^n = \frac{9998}{10000}$

Convert fraction to decimal

$1 - q^n = 0.9998$

Add $q^n$ to both sides

$1 - q^n + q^n= 0.9998 + q^n$

$1 = 0.9998 + q^n$

Subtract 0.9998 from both sides

$1 - 0.9998 = 0.9998 - 0.9998 + q^n$

$1 - 0.9998 = q^n$

$0.0002 = q^n$

Recall that $q = 0.05$

So, the expression becomes

$0.0002 = 0.05^n$

Take Log of both sides

$Log(0.0002) = Log(0.05^n)$

From laws of logarithm $Loga^b = bLoga$

So,

$Log(0.0002) = Log(0.05^n)$ becomes

$Log(0.0002) = nLog(0.05)$

Divide both sides by $Log0.05$

$\frac{Log(0.0002)}{Log(0.05)} = \frac{nLog(0.05)}{Log(0.05)}$

$\frac{Log(0.0002)}{Log(0.05)} = n$

$n = \frac{Log(0.0002)}{Log(0.05)}$

$n = \frac{-3.69897000434}{-1.30102999566}$

$n = 2.84310893421$

$n = 3 (Approximated)$

<em>Hence, the smallest number of servers required is 3 servers</em>

A disciplined, creative, and effective approach to problem solving is needed for project success. The nine-step approach to prob

KatRina [158]

Answer: Determine the most popular solution.

Explanation:

Some of the approaches to problem solving that are listed here include:

• Gather data and verify the most likely causes.

• Revise the project plan.

• Evaluate the alternative solutions

To solve a problem, one needs to gather the data and verify the likely causes of the problem. This can be done by asking questions, running test, interviewing people, running tests, reading reports, or analyzing data.

The project plan can also be revised. Likewise, when one comes with different solutions, one should weigh the cost and benefits of each in order to choose the best solution.

Determine the most popular solution isn't a correct option.
