For a weighted arithmetic mean wherew= (0.4,0.2,0.2,0.2) andx= (0.3,0.9,1,0), which of the following is true? Select all that apply.

(Note that if you select an incorrect answer in the MCQ, then you will anegativescore. Withoutnegativescoring, students can select all answers to get full marks.)

Options:

• The first input (for most vectorsx)has a relatively higher influence on the function than the other inputs, which are equally important.

• The output of the function will be zero because the fourth input is zero.

• The last input has no influence on the output of the function.

• Although it will not be the case this time, the function usually tends towards higher values.
