A  cold  wave  gripped  much  of  the  united  states  during  the  first  week  of  february  1996.    the  lowest temperatures  in  four  ohio  cities  those  weeks  were:   cleveland  ‐10 degrees f;   columbus -3 degrees f;   toledo  ‐8 degrees f;   cincinnati  ‐11 degrees f.  what  was  the  average  lowest  temperature  for  these  cities?

Add up your values and divide by the number of cities. So-32/4 = -8

Your average temperature would be -8, as -10, -8, -3, and -11 add to -32, which divides by four to become -8. This is the median.

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

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
