Anyone know how to do this?

Determine the difference: 3.2 × 1010 – 1.1 × 1010. write your answer in scientific notation.

How do you create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1?

Ialready asked this but i never got an answer. will give a high rating and perhaps brainliest. choose the linear inequality that describes the graph. the gray area represents the shaded region. y ≤ –4x – 2 y > –4x – 2 y ≥ –4x – 2 y < 4x – 2
