The first one is not a question. Rather it is the parameters in which the second question exists.

2.

49.85%

This is because the likelihood of a point being within 2 SDs of the mean is 99.7%. This leaves .15 above and .15 below that curve. Given that we are looking from the mean (50%) and the upper limit with the exception of that .15, we would get the answer above.

Which of the following statements uses the additive identity? 9 + 0 = 9 9 · 0 = 0 9 + 1 = 1 + 9 (9)(1) = (1)(9)

m_a_m_a [10]

<h3>Answer: 9+0 = 9</h3>

The additive identity is 0. If you add 0 to any number, then you get the same number as a result. In general, x+0 = x where x is a place holder for any number. For this problem, x = 9 so that's how 9+0 = 9.
