Glenny is saying that these hackers' motivations for doing what they do are a result of their upbringing and other experiences that have shaped who they are. Refresh your knowledge of both new and ancient hacker kinds. In the field of information security, there are three well-known categories of hackers: black hats, white hats, and grey hats.
In an effort to set themselves apart from one another and distinguish the good hackers from the evil, hackers created these colored hat descriptors. The majority of cyberattacks target small and medium-sized businesses. Unlike huge corporations, which are financially and materially capable of funding cyber security.

Answer: Price decreased by 12%
Explanation:
Price elasticity = %Change in quantity / % change in price
0.5 = 6% / % change in price
0.5 * % change in price = 6%
% change in price = 6%/0.5
% change in price = 12%
Answer:
the client should wait 10 more years until the contract is worth $180,000 since he will earn a slightly higher interest rate
Explanation:
we must determine the effective interest earned by the client if he accepts the company's proposal:
future value = present value x (1 + r)ⁿ
121,000 = 100,000 x (1 + r)⁵
(1 + r)⁵ = 121,000 / 100,000 = 1.21
⁵√(1 + r)⁵ = ⁵√1.21
1 + r = 1.0389
r = 0.0389 = 3.89%
if the client waits 10 more years until he is able to annuitize the account, he should earn:
180,000 = 100,000 x (1 + r)¹⁵
(1 + r)¹⁵ = 180,000 / 100,000 = 1.80
¹⁵√(1 + r)¹⁵ = ¹⁵√1.80
1 + r = 1.03996
r = 0.03996 = 4%
Answer: Real estate
Explanation: Liquidity refers to the ability of a security to be converted into cash without having a major change in its price. In other words, liquidity is the relationship between the speed of sale of a security and its change in price.
Real estate refers to the land or other housing facilities etc. These assets require huge amount for purchase. It takes to find a buyer willing to make such a big investment, thus, they are not liquid.
Hence from the above we can conclude that the right option is C.
Answer:
1.08
Explanation:
The computation of the portfolio beta is shown below:
Portfolio beta is
= Invested stock percentage × beta of the stock + Invested stock percentage × beta of the stock + Invested stock percentage × beta of the stock
= 0.50 × 1.50 + 0.30 × 0.90 + 0.20 × 0.30
= 1.08
We simply applied the above formula so that the portfolio beta could come and the same is to be considered
