A local sandwich shop makes an Italian sandwich that contains ham, salami, and pepperoni meats. Let X represent the weight of ham, Y represent the weight of salami, and Z represent the weight of pepperoni for each Italian sandwich made. The mean of X is 2 ounces, the mean of Y is 1.25 ounces, and the mean of Z is 1.75 ounces. What is the mean of the sum, S = X + Y + Z?

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

sine

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
