The equation that is equivalent is -2+(-7).
1/40 of 2,000 is 500.
Divide 2,000 by 40 to figure out what 1/40 of 2,000 is.
A quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression (e.g. 3 in 23 = 2 × 2 × 2).
Answer: See below.
You would sketch a traditional bell curve. For middle line (the highest point of the circle), you would label it with the mead of 50.
Going to the right, you would draw 3 vertical lines. The lines would count up by 2 for each standard deviation. 52, 54, 56
Going to the left, you would draw 3 vertical lines. The lines would count down by 2 for each standard deviation. 48, 46, 44
Yes.
Proof: Consider x, y in R^m. Then since T is linear, we have:
T(a*x + b*y) = a*T(x) + b*T(y)
But since L is linear, we have:
L(a*T(x) + b*T(y)) = a*L(T(x)) + b*L(T(y))
So:
L(T(a*x + b*y)) = a*L(T(x)) + b*L(T(y))
and the composition is linear.
