<h3>What is database?</h3>
A database is a structured information collection which is often stored electronically in a computer system. Generally, a database management system is in charge of managing a database (DBMS). A database system, frequently abbreviated to just database, is the collective term for the data, the DBMS, and the applications that are connected to it.
The most popular forms of databases in use today typically describe their data in rows and columns in a collection of tables to facilitate processing and data querying. The information can then be accessed, managed, changed, updated, regulated, and organized with ease. SQL is a structured query language that is used by the majority of databases to write and query data.

Answer:
Expected return is: 7.37% and the Standard deviation is: 24.96%
Explanation:
Correlation between fund S&B=0,0667
Standard Deviation of Fund S=41%
Standard Deviation of Fund(B)=30%
E(R) of Stock Fund S=12%
E(R) of Stock Fund B=5%
Covariance between the funds = Standard Deviation of Fund(B) × Standard Deviation of Fund S × correlation between these funds
Cov = 0.41 × 0.30 × 0.0667 = 0.008204
Now minimum variance portfolio is found by applying:
W min(S)=(SDB)^2-Cov(B,S) / ((SDS)^2+(SDB)^2-2Cov(B,S)
W min(S) = 0.338431
W min(B) = 1-0.338431=0.661569
1) E(r)min= 0.338431 × 12% + 0.661569 × 5% = 7.37%
2) Standard Deviation:
SD Min = (Ws^2XSDs^2+Wb^2XSDb^2+2XWsWb*Cov(s,B)^1/2
SDmin=(0.338431^2 × 0.41^2 + 0.661569^2 × 0.3^2 + 2 × 0.338431 × 0.661569 × 0.008204)^1/2
SDmin=24.96%
Answer: d. path–goal
Explanation:
The Path-goal theory of leadership espouses that leaders should be dynamic and use whichever leadership style would be best suited to the abilities of their subordinates and the work environment that they are in.
It is then divided into four styles with the relevant style here being the "directive path-goal clarifying leader behavior". Under this style, the manager specifies exactly what it is that they want from the employees and then rewards them when they meet the required objectives.
Answer:
E decrease the product price
Explanation:
Maturity stage of the product is the stage where the product has already saturated in the market and sales begin to peak and slow down. Many companies will want to maintain this stage when it peaks but when the decline starts showing up it is a great challenge for them due to competition that cuts in from other companies. so companies at maturity stage would want to adopt the method of decreasing the price of the product in order to fight off competition.
