Perimeter = 4*(3*x+2) = 12*x +8
So 12x +8 is the answer.
It’s the replacement of the Lena and width of the x+y
Answer:
a) Simple random sample
b) Random sample
c) None of them.
Step-by-step explanation:
a) This would be a simple random sample given that the dice roll is a random method to select the students and the probability of each outcome of the dice is 1/6.
b) This would be a random sample, given that the cards are shuffled, this is a random event. However, there's a condition on how to select the cards (The top ones are chosen) and therefore this can not be a simple random sample since not all cards have the same probability of being selected.
c) This is not a random sample since there is an specific condition on how to choose the students (by their age)

f(x) = x^3 + x^2 + 3x^0 is neither even nor odd. Why? Because we have a mixture of even and odd powers of x here: x^3 (odd) and x^2 and x^0 (even).
Even functions: all component functions are even (e. g., x^2 and x^0).
Odd functions: all component functions are odd (e. g., x^5 and x^3.
Neither: There's a mixture of even ad odd functions.
Another way to test for even, odd or neither:
Even functions: f(-x) = f(x). Changing the sign of the input (x) doesn't change the sign of the output.
Odd functions: f(-x) = -f(x). Changing the sign of the input changes the sign of the output.
