Answer:
Positive correlation
Step-by-step explanation:
Correlation:
- Correlation is a technique that help us to find or define a linear relationship between two variables.
- It is a measure of linear relationship between two quantities.
- A positive correlation means that an increase in one quantity leads to an increase in another quantity
- A negative correlation means with increase in one quantity the other quantity decreases.
- Positive correlation means that the data sets are directly related with each other.
Thus, the correct answer is
Positive correlation
Answer:
The standard deviation is 10.38
Step-by-step explanation:
Given;
Variance, v = 107.76
mean, x = 34.2
The standard deviation is given by;
standard deviation = √variance
standard deviation = √107.76
standard deviation = 10.381
standard deviation = 10.38 (two decimal places)
Therefore, the standard deviation is 10.38
Answer:
symmetric matrix is the square matrix and it is equal to its transpose
Step-by-step explanation:
solution
a symmetric matrix is the square matrix and it is equal to its transpose
As A is symmetric matrix then
A = 
here only square matrices will be symmetric
and matrix A is symmetric its mean its matrices have equal dimension
and every square diagonal matrix is also symmetric when all off diagonals element is zero
symmetric matrix for all indices i and j
A = aij = aji
You have to cancel out the variables and then you plug it into a calculator.
My first rectangle is 1 unit wide and 24 units long. Its area
is 24 square units and its perimeter is 50 units.
My second rectangle is 2 units wide and 12 units long. Its area
is 24 square units and its perimeter is 28 units.
My third rectangle is 3 units wide and 8 units long. Its area
is 24 square units and its perimeter is 22 units.
My fourth rectangle is 4 units wide and 6 units long. Its area
is 24 square units and its perimeter is 20 units.
