Answer:

Largest possible rank =6

Minimum possible rank=0

Step-by-step explanation:

We are given that A is a matrix of order 6\times 9

We have to find the maximum possible rank and minimum possible rank of A.

In given matrix we have 6 rows and 9 columns.

Rank: Rank is defined as the number of non zero rows or columns of matrix and any row or column is not a linear  combination of other two or more rows or columns

Rank of matrix of order m\times n

Where m< n

Then largest possible rank is m

We are given a matrix of order6\times 9 where 6< 9

Therefore, the largest possible rank is 6.

The minimum possible rank  is zero because a  given matrix can be zero matrix therefore, the rank of zero matrix is zero.

Largest possible rank =6

Minimum possible rank=0

In order to make a service for four 1 3/4 cups of chopped vegetables are needed. Based on this information, determine the amount
Mila [183]

For this case we propose a rule of three according to the data of the statement. To do this, we convert the mixed number into an improper fraction:

1 \frac {3} {4} = \frac {4 * 1 + 3} {4} = \frac {7} {4}cups

4 ----------> \frac {7} {4}

10 ----------> x

Where the variable "x" represents the amount of chopped of vegetables needed for 10 people.

x = \frac {10 * \frac {7} {4}} {4}\\x = \frac {\frac {70} {4}} {4}\\x = \frac {70} {16}\\x = \frac {35} {8}

This is equivalent to 4 \frac {3} {8}cups.

Answer:

4 \frac {3} {8} cups
