The measurement problems that exist in the radar equipment are accuracy
, reliability
<u>Explanation:</u>
There are two different kinds of Radar that is being used such as rotating- antenna radar and traffic radar. The type of radar that is being used by police contains a stationary single antenna. this will be pointing in one direction. The signal that is modulated will not be sent. There will not be any cathode ray screen for displaying the collected information.
As the antenna points only one direction it can measure only the speed of those object that is either moving towards or away from the radar. It cannot sense the kind of object that it is measuring and it could not also tell the direction in which the object is travelling. Hence, the reliability and the accuracy are the main measurement problems.
Answer:
a)
Explanation:
Phishing is a type of deception in which an intruder disguises himself in email or other means of communication as a reputable individual or person. Attackers would normally use phishing e-mails to spread a range of malicious links or attachments. Some people will gather login credentials or victims' account details.

Answer:
23.25%; 62.01%
Explanation:
(a) Amount received:
= No. of shares × selling price
= 100 × $43
= $4,300
Sales deposit = 60% of Amount received
= 0.6 × $4,300
= $2,580
Amount paid = No. of shares × Purchase price
= 100 × $49
= $4,900
Therefore, Loss = $4,900 - $4,300
= $600
(b) If buys at $27, then
Amount paid = $27 × 100
= $2,700
Profit = $4,300 - $2,700
= $1,600
Loss on investment:
= ($600 ÷ $2,580) × 100
= 23.25%
Profit on investment:
= ($1,600 ÷ $2,580) × 100
= 62.01%
<u>Solution and Explanation:</u>
As the utility function is concave in shape, so person is risk averse. Thus, he will not accept the gamvle.
The difference between utility at point A&C = 70 minus 65 = $5, is less than a the difference between A&B = 65 minus 55 = $10
<u>MCQ:
</u>
Answer is option a&d - risk averse people fear a lot for losing money, thus they overestimate the probability of loss
Since, shape of utility function is concave, hence the double derivative of utility with respect to wealth is negative, so utility falls at an decreasing rate , as wealth increases
