rocky???
Step-by-step explanation:
5/2 3/8
Given:
The matrix multiplication
To find:
The order of resulting matrix.
Solution:
We know that, if order of first matrix is 
and the order of second matrix is 
, then the order of these two matrices is 
.
We have,
Here, the order of first matrix is 
and the order of the second matrix is 
. So, the order of the second matrix is 
. It is also written are 2 by 1.
Therefore, the correct option is A.
If the mean is 32 and there is 4 numbers
then the numbers add to 32x4 which is 128
128-15-21-75=17
fourth number is 17
Answer:
Age of ben = n years
Age of Chloe = 2n years
Age of Dan = (n - 5) years
Now,
Sum of ben, Chloe and Dan's age = t years
or, n +2n + n - 5 = t
or, 4n - 5 =t
This is the required formula
Answer:
no it is not, A
Step-by-step explanation:
functions are things which u can draw vertical lines through and it never intersects(one x value leads to exactly one y value) at more than one point so A because x=7 is infinite y values for one x value.
