arsen [322]

Answer:

the data are inadequate

Explanation:

<u>If there are 15 people on the team, and only five have been asked about the mascot, </u><u>this means the data collecting is wrong, and the result doesn’t include thoughts of the majority</u>. If Diana and Kinsey want to have adequate data,<u> they should ask as many as possible, if not all players in the team</u>. This would truly show what the majority wants meaning it will show what the team wants. This kind of complete data correcting is the correct one.

"Carbon 14 (C-14), a radioactive isotope of carbon, has a half-life of 5730 ± 40 years. Measuring the amount of this isotope lef

Answer:

The age of the bones is approximately 14172 years.

Explanation:

The age of the bones can be determinated using the following decay equation:

N_{(t)} = N_{0}e^{-\lambda t}   (1)

<u>Where:</u>

N(t): is the quantity of C-14 at time t

No: is the initial quantity of C-14  

λ: is the decay rate      

t: is the time

First, we need to find λ:

\lambda = \frac{ln(2)}{t_{1/2}}

<u>Where:</u>

t(1/2): is the half-life of C-14 = 5730 y

\lambda = \frac{ln(2)}{5730 y} = 1.21 \cdot 10^{-04} y^{-1}

Now, we can calculate the age of the bones by solving equation (1) for t:

t = \frac{-ln(\frac{N_{(t)}}{N_{0}})}{\lambda}

We know that the bones have lost 82% of the C-14 they originally contained, so:

N_{t} = (1 - 0.82)N_{0} = 0.18N_{0}

t = \frac{-ln(0.18)}{1.21 \cdot 10^{-04} y^{-1}}

t = 14172 y

Therefore, the age of the bones is approximately 14172 years.

I hope it helps you!

What is the best countermeasure against social engineering?
Mkey [24]

Answer:

Hello Monk7294!

Answer:

Employee education

Explanation:

The most important countermeasure for social engineering is employee education. All the employees should be trained to keep confidential data safe. As a part of security education, organizations have to provide timely orientation about their security policy to new employees. The security policy should address the consequences of the breaches.
