Answer:
The answer is A
Step-by-step explanation:
You should set "I" as
1 0 0
0 1 0
0 0 1
then replace "a" to 0.5 and "b" to 0.1
then finally you multiply matrice C and D
If your answer is
1 0 0
0 1 0
0 0 1
then the answer will be A
Answer:
2/3
Step-by-step explanation:
1-(-7)=8 8/12 simplify= 2/3
9-(-3)=12
Answer:
-54
Step-by-step explanation:
8a + 7b + c = 9
We want -6c, but we have c in the equation so multiply by -6
-6(8a + 7b + c) = 9*-6
-48a -42b -6c = -54
Rearranging the equation
-6c - 48a - 42b = -54
The median is 7.
——————————
Arrange data in numerical order
1 3 3 6 8 10 10 15
Total number are 8, N = 8
Take the middle two numbers 6 and 8 and take their average
6+8/2 = 14/2 = 7
Therefore the median is 7.
