Anything with a zero denominator is undefined.
Answer:
Therefore Rotten Tomato ratings explain about 75% of the variation in Metascore ratings is the correct answer here.
Step-by-step explanation:
The R2 value for regression or the coefficient of determination represents the proportion of variation in dependent variable that is explained by regression ( the rest of it is residual variation )
Answer:
7 times p
7 multiplied by p
The product of 7 and p
Step-by-step explanation:
The question is <em>7p</em>. Usually, when a number and a variable is placed side by side, it means you are multiplying:
7 times p
7 multiplied by p
The product of 7 and p
are all your answer choices, for they all deal with multiplying 7 with <em>p</em>.

Question: If the subspace of all solutions of
Ax = 0
has a basis consisting of vectors and if A is a matrix, what is the rank of A.
Note: The rank of A can only be determined if the dimension of the matrix A is given, and the number of vectors is known. Here in this question, neither the dimension, nor the number of vectors is given.
Assume: The number of vectors is 3, and the dimension is 5 × 8.
Answer:
The rank of the matrix A is 5.
Step-by-step explanation:
In the standard basis of the linear transformation:
f : R^8 → R^5, x↦Ax
the matrix A is a representation.
and the dimension of kernel of A, written as dim(kerA) is 3.
By the rank-nullity theorem, rank of matrix A is equal to the subtraction of the dimension of the kernel of A from the dimension of R^8.
That is:
rank(A) = dim(R^8) - dim(kerA)
= 8 - 3
= 5
