Answer:
g(f(2)) = 9
Step-by-step explanation:
Evaluate f(2) and substitute the value obtained into g(x)
f(2) = 2 + 1 = 3 , then
g(3) = 3² = 9
Answer:
The given statement is true.
Step-by-step explanation:
Regression Analysis:
- Regression analysis is a technique that help us to find or define a relationship between a dependent and an independent variable.
- It helps us to predict the dependent variables with the help of independent variables.
- Various techniques are used for the prediction of independent variable.
- It is a type of predictive statistical technique and helps us to find whether there is a significant relationship between the dependent and the independent variable.
Correlation analysis:
- Correlation is a technique that help us to find or define a relationship between two variables.
- It is a measure of linear relationship between two quantities.
- It is not necessary that the that out of the two variable one needs to be dependent and the other to be independent.
- Correlation can be positive, negative or zero correlation.
Thus, the given statement is true.
Answer:
k=3
Step-by-step explanation:
The given system of equations are
We need to find the value of k if the given system of equation have infinite number of solutions.
If two equations 
and 
have infinite number of solutions, then
Using this we get
Therefore, the value of k is 3.
