The purpose of maintaining a network of digital forensics specialists is to develop a list of colleagues who specialize in areas

Rudiy27

Answer:

True

Explanation:

Computer security is basically divided into three main areas:

Vulnerability/threat assessment and risk management refers to a process that requires the identification, quantification and ranking of a system's possible vulnerabilities.
network intrusion detection and incident response refers to software that detects malicious activity or policy violations, and blocks them
digital forensic investigation refers to the process of identifying, recovering and interpreting (or validating) electronic data.

Generally a single individual may specialize in one of these areas, that is why he/she may need help with the others.

What was one important academic skill the blogger learned?

denis23 [38]

An academic skill that the blogger learned, was to review the graded tests and quizzes to see which concepts he missed out on so that in the future he would be well prepared for it. Reviewing and comparing the tests and quizzes would give him an idea on which topics he needs to study.

Other than the academic skill, the blogger also learned that a person should never give up and he keeps on learning throughout his entire life, and that all of the improvements that the blogger made did not come all at once.

Simora [160]

Answer:

The answer is " $\bold{Brand \ A \ (35, 350, 18.7) \ \ Brand \ B \ (35, 50, 7.07)}$ "

Explanation:

Calculating the mean for brand A:

$\to \bar{X_{A}}=\frac{10+60+50+30+40+20}{6} =\frac{210}{6}=35$

Calculating the Variance for brand A:

$\sigma_{A}^{2}=\frac{\left ( 10-35 \right )^{2}+\left ( 60-35 \right )^{2}+\left ( 50-35 \right )^{2}+\left ( 30-35 \right )^{2}+\left ( 40-35 \right )^{2}+\left ( 20-35 \right )^{2}}{5} \\\\$

$=\frac{\left ( -25 \right )^{2}+\left ( 25 \right )^{2}+\left ( 15\right )^{2}+\left ( -5 \right )^{2}+\left ( 5 \right )^{2}+\left ( 15 \right )^{2}}{5} \\\\ =\frac{625+ 625+225+25+25+225}{5} \\\\ =\frac{1750}{50}\\\\=350$

Calculating the Standard deviation:

$\sigma _{A}=\sqrt{\sigma _{A}^{2}}=18.7$

Calculating the Mean for brand B:

$\bar{X_{B}}=\frac{35+45+30+35+40+25}{6}=\frac{210}{6}=35$

Calculating the Variance for brand B:

$\sigma_{B} ^{2}=\frac{\left ( 35-35 \right )^{2}+\left ( 45-35 \right )^{2}+\left ( 30-35 \right )^{2}+\left ( 35-35 \right )^{2}+\left ( 40-35 \right )^{2}+\left ( 25-35 \right )^{2}}{5}$

$=\frac{\left ( 0 \right )^{2}+\left ( 10 \right )^{2}+\left ( -5 \right )^{2}+\left (0 \right )^{2}+\left ( 5 \right )^{2}+\left ( -10 \right )^{2}}{5}\\\\=\frac{0+100+25+0+25+100}{5}\\\\=\frac{100+25+25+100}{5}\\\\=\frac{250}{5}\\\\=50$

Calculating the Standard deviation:

$\sigma _{B}=\sqrt{\sigma _{B}^{2}}=7.07$
