describe how to sketch a normal curve with a mean of 50 and a standard deviation of 2 indicate how you would label the horizonta

Zepler [3.9K]

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

Consider two linear transformations y = T(x) and z = L(y), where T goes from R^m to R^p and L goes from R^p to R^n. Is the trans

lapo4ka [179]

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.
