Answer:
Step-by-step explanation:
Number of cats at veterinarian office = 2
Number of dogs at veterinarian office = 4
Total number of pets at veterinarian office = 2 + 4 = 6
Now, we need to find probability that 2 cats are seen in a row
⇒ No dog is seen between two cats
So, to find the required probability :
No. of favorable outcomes = 2
Total number of outcomes = 6

Answer:
Five
Step-by-step explanation:
Pivot columns are said to be columns where pivot exist and a pivot exist in the first nonzero entry of each row in a matrix that is in a shape resulting from a Gaussian elimination.
Suppose A = 5 × 7 matrix
So; if A columns span set of real numbers R⁵
The number of pivot columns that A must have must be present in each row. In a 5 × 7 matrix ; we have 5 rows and 7 columns . So , since A must be present in each row, then :
The matrix must have five pivot columns and we can infer that about the statements that "A has a pivot position in every row" and "the columns of A spans R⁵" are logically equivalent.
