A political candidate has asked his/her assistant to conduct a poll to determine the percentage of people in the community that
Alexxandr [17]

Answer:

The size of the sample needed = 67.65

Explanation:

Given that :

The margin of error = 10% = 0.10

The confidence level = 90% = 0.90

Level of significance = 1 - 0.90 = 0.10

At ∝ = 0.10

Z_{\alpha/2}= Z_{0.10/2} = 1.645

Since the proportion of people that supported him/her is not given, we assumed p = 0.50

The margin of error formula can be expressed as:

M.O.E = Z_{\alpha/2} \times \sqrt{\dfrac{p(1-p)}{n}}

0.10 = 1.645 \times \sqrt{{\dfrac{0.5(1-0.5)}{n}

Squaring both sides; we have:

0.10^2 = 1.645^2 \times {\dfrac{0.5(1-0.5)}{n}

0.01 = 2.706025 \times \dfrac{0.25}{n}

n= 2.706025 \times \dfrac{0.25}{0.01 }

n = 67.65

Therefore, the required sample size = 67.65

PHYSICAL SECURITY
Kitty [74]

We can see that within a secure area, you see an individual who you do not know and is not wearing a visible badge. This is a potential security breach that could compromise the safety and integrity of the secure area and its assets.

<h3>What is physical security?</h3>

Physical security is the protection of personnel, hardware, software, networks, and data from physical actions and events that could cause serious loss or damage to an organization, agency, or institution. This includes protection from fire, flood, natural disasters, burglary, theft, vandalism, and terrorism.

Within a secure area, you see an individual who you do not know and is not wearing a visible badge. This is a potential security breach that could compromise the safety and integrity of the secure area and its assets. Thus, the follows measures should be taken to address the situation stated above:

1. Approach the individual in a polite and professional manner and ask for their name, purpose, and authorization to be in the secure area. If they have a valid badge, ask them to display it visibly. If they do not have a badge, ask them to accompany you to the nearest security checkpoint or office.

2. If the individual refuses to cooperate, becomes hostile, or tries to evade you, do not attempt to physically restrain or confront them. Instead, alert the security personnel or supervisor immediately and provide a description of the individual and their location. Keep a safe distance and observe the individual until security arrives.

3. If the individual claims to have a valid reason to be in the secure area but does not have a badge, verify their identity and authorization with the appropriate personnel or department. For example, if they are a contractor, vendor, or visitor, check their credentials and contact their sponsor or host. If they are an employee, check their employee ID and contact their manager or supervisor.

4. If the individual is authorized to be in the secure area but does not have a badge, escort them to the security office or checkpoint and request a temporary or replacement badge. Explain the importance of wearing a badge at all times and the consequences of violating the security policy.

5. If the individual is not authorized to be in the secure area, detain them in the security office or checkpoint and notify the security personnel or supervisor. Follow the security procedures and protocols for handling unauthorized intruders or trespassers. Report the incident and provide any relevant information or evidence to the security personnel or supervisor.

karen performs a transformation on parallelogram syntax error from line 1 column 49 to line 1 column 73. unexpected 'mathsize'.
Travka [436]

The transformation performed by Karen is 90 degrees counterclockwise rotation across the origin.

The table is given as:

<u>Original  point ---- Image</u>

A (-4,-1)                  (1,-4)

B (-7,-6)                 (6,-7)

C (-14, -6)              (6,-14)

D (-11, -1)               (1,-11)

From the table, we can see that;

The coordinates are swapped, and the new x-coordinate is negated.

This represents 90 degrees counterclockwise rotation across the origin.

The rule of this transformation is:

(x,y) \to (-y,x)

i.e.

(-4,-1) \to (1,-4)

(-7,-6)      \to           (6,-7)

(-14, -6)  \to            (6,-14)

(-11, -1)            \to   (1,-11)

Hence, the transformation performed by Karen is 90 degrees counterclockwise rotation across the origin.
