Question

Suppose the MATLAB variable exampleArray is defined by:

exampleArray = [4, 6, 10; 11, 7, 6; 0, -1, -4];
Click on the array that shows the results of the MATLAB command: x = mean(exampleArray)

Options:
A) [5, 4, 4]
B) [5, 4, 1]
C) [5, 4, 4.6667]
D) [5, 4, 2]

Answer 1

The MATLAB command 'x = mean(exampleArray)' calculates the mean of the elements in the array 'exampleArray'. The mean values for the columns of 'exampleArray' are [5, 4, 4.6667].

Step-by-step explanation:

The MATLAB command 'x = mean(exampleArray)' calculates the mean of the elements in the array 'exampleArray'. The mean is the sum of all the elements divided by the total number of elements in the array. In this case, the array 'exampleArray' has 9 elements, so the mean is calculated by adding up all the elements and dividing by 9. The result of the calculation is an array with the mean values for each column of 'exampleArray'.

In this case, the mean values for the columns of 'exampleArray' are [5, 4, 4.6667]. Therefore, the correct answer is C) [5, 4, 4.6667].
