Aset of data is described as: the data is around 7. if another measurement were taken it would probably be around 7. which group of measures would lead to this conclusion? range—10 mode—7 median—9 mean—5 range—4 mode—6 median—7 mean—8 range—12 mode—9 median—9 mean—9 range—5 mode—9 median—9 mean—7

easy math just plug in a and b

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

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
