Answer:
2.6i
Step-by-step explanation:
undo the - by making it: √-6.76= √6.76 x √-1
then, √-1 would be converted to imaginary number -> i
now rewrite it as √6.76 x i or i√6.76 which is the same as the squareroot of 6.76 which is 2.6 times i.
Then just write your final answer as 2.6i
Answer:
In economics, a portfolio is a term for a specific set of stocks, bonds, shares, and other securities owned by an investor. In general, the investor seeks to compile and diversify a portfolio of securities that offers maximum profitability and at the same time is diverse, in order to minimize possible risks. In general, these types of portfolios are considered efficient, as they do not leave the investment risk tied to a single factor. However, these two goals often go against each other, so the composition of the portfolio means a certain compromise.
Answer:
663
Step-by-step explanation:
ratio of Malay = 5
ratio of Indian= 4
ratio of Chinese= 8
Total number of Indian + Chinese= 468
Total ratio= 5+4+8= 17
Let the total number of students= X
Ratio of India= 4/17 × X=
Ratio of Chinese= 8/17 × X=
Addition of ratio of both India and Chinese=
4X/17 + 8X/17= 468
(4X +8X)/17 = 468
12X/17= 468
X= 663
Hence, total number of students is 663
Answer:
2
Step-by-step explanation:
We are given that Ticket writing on campus follows a Poisson process.
Last year the campus police wrote 1460 tickets
So, 
1 year = 365 days
So, E(Y) =
So, the standard deviation of the number of tickets written per day by the campus police = 
Hence the standard deviation of the number of tickets written per day by the campus police is 2
The answer for 9 and 10 is B
