Answer:
Step-by-step explanation:
Given that A is a square matrix and A is idempotent
Consider I-A
i) 
It follows that I-A is also idempotent
ii) Consider the matrix 2A-I
So it follows that 2A-I matrix is its own inverse.
Use the binomial expansion theorem to find and simplify each term.
x^6 + 24x^5 + 240x^4 - 1280x^3 + 3840x^2 - 6144x + 4096

Answer:
1. 228 parents
Step-by-step explanation:
I will do number 1 for you. I'll let you or someone else do the others.
Let 10x = no. of girls
5x = no. of boys
4x = no. of parents
Now, 10x + 5x + 4x = 1083
19x = 1083
x = 57
(10)(57) = 570 girls
(5)(57) = 285 boys
(4)(57) = <u>228 parents</u>
1083 total

Answer:
5
Step-by-step explanation:
The answer is 5. The median is the middle number in a list of sorted numbers. Here when sorted we get 2, 3, 4, 6, 8, 8. However, we have an even number of terms so the answer is in between the two middle numbers. Here that is 5.
