Which question will give data that has a measure of center and variation?

what is the height of my teacher?

how many students in my class like algebra?

what is the weight of each student in my class?

how long was the winter vacation for each student in my class?

answer:   second and third option are correct.

step-by-step explanation:

measure of center and variation means

measure of center would contain mean, median and mode which is also known as central tendency.

and measure of variation would contain "range", difference between highest and lowest.

so, those questions which will give data that has a measure of center and variation would be

1) how many students in my class like algebra?

2) what is the weight of each student in my class?

hence, second and third option are correct.

answer: it is a.,b.,d.

step-by-step explanation:

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
