Answer:

True

Step-by-step explanation:

When we represent a distribution we can analyze its level of symmetry: a distribution is symmetric if in relation to a central value the distribution is distributed 50% to the right and another 50% to the left, presenting a similar shape on both sides of the central value .

If, on the other hand, the distribution presents a more lean form to the left, we speak of positive asymmetry; and if it is more to the right, of negative asymmetry. In these cases, the asymmetry causes the z-score values of +1.0 to have a different value than the one corresponding to -1.0, since the precise figure of a bell is not obtained.

In conclusion, the statement is true.

Hope this helps!

Please help find surface area!!
NeTakaya

Answer:

138 cm.

Step-by-step explanation:

So first, we find the S.A. of the front and back.

The diagram says the side length of the front is 3 cm. and 3 cm.

3x3=9. So then, the back is also 9 cm, 9+9=18.

Now to find the S.A.'s of the four sides, you have to see the side lengths of each of them. The side lengths are 3 and 10.

3x10=30. This means each of them is 30 cm.

30x4=120. 120 is the total surface area of the four sides.

To find the total surface area of the whole rectangle, you add all the surface areas.

120+18=138 cm. (Not squared, since it's surface area and not area.)
