Answer:
categorical ordinal
Step-by-step explanation:
The variable is categorical because not important, somewhat important and very important are three different categories and these categories are assigned numerical value 1,2 and 3 still numerical value assigning cannot lead to quantitative variable because 1 still means category not important. The scale of measurement in the variable is ordinal because it has meaningful order from category 1 not important to category 3 very important.
A matrix is diagonal if

In other words, you want non-zero elements only when the indices of the row and the column are the same: the first element of the first row must be non zero, the second element of the second row must be non-zero, and so on. All other elements must be zero.
Answer:
16
Step-by-step explanation:
Given that:
Length of two sides of the triangle = 1 and 16 ;
The largest possible whole-number length of the third side would be ;
Recall from triangle inequality theorem; the length of any two sides of a triangle is greater than the third side. Therefore. The largest possible whole number value the third side could have is:
Assume the third side is the largest :
Then, the third side must be less than the sum of the other two sides ;
Third side < (16 + 1)
Third side < 17
Therefore, the closest whole number lesser than the sum of the other two sides is (17 - 1) = 16
The answer of the question is C
