What is the data set's level of measurement? a. ratio, because the differences in the data can be meaningfully measured, and the data have a true zero point. b. nominal, because the data are categories or labels that cannot be ranked. c. ordinal, because the data are categories or labels that can be ranked. d. interval, because the differences in the data can be meaningfully measured, but the data do not have a true zero point.

answer: the common difference is -0.10

m a t h w a y. c o m

step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

it has changed from the width and the height.
