Mean is 30,median is 30.5,mode is 31.
Answer:
1,215 i think please be right
I hope this picture helps. I'll elaborate if needed!
If the number is n then
square of 2 times a number
square of 2n
(2n)²
that was your mistake, because (2n)²=4n², not 2n²
the result is 81
(2n)²=81
square root both sides
remember positive and negative roots
2n=+/-9
divide by 2
n=+/-4.5
n=4.5 or -4.5
The correct answer for this statement would be TRUE. Yes,it is true that the identity function is a linear function. <span>A linear function is a map between two vector spaces that preserves vector addition and scalar multiplication.
</span>this means f(x + y) = f(x) + f(y) and f(xy) = f(x)f(y))
<span>The identity function is the function such that f(x) = x
</span>So by using this example, we can conclude that it is a linear function.
