Asingle penny has a mass of 2.5 g. abbie and
james each measure the mass of a penny multiple
times. which statement about these data sets is
true?
abbie's measurements are both more
accurate and more precise than james'.
abbie's measurements are more accurate, but
less precise than james'.
o
abbie's measurements are more precise, but
less accurate than james'
abbie's measurements are both less accurate
and less precise than james'.

the answer is c

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
