Me i don't know this i'm not good at math ☺️2 and3

me neither :c

Step-by-step explanation:

Problem 2

This is because it is the most frequent value in the list (ie it shows up the most). The value 40 shows up twice while every other value only shows up once.

Problem 3

To get the mean, you add up the time values to get 39+42+41+38+39+39+42 = 280

Then divide that result by 7 since there are 7 values, so we get 280/7 = 40

square root

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
