Create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1.

Arefrigeration system at your company uses temperature sensors fixed to read celsius (°c) values, but the system operators in your control room understand only the fahrenheit scale. you have been asked to make a fahrenheit (°f) label for the high temperature alarm, which is set to ring whenever the system temperature rises above –10°c. what fahrenheit value should you write on the label?

Cos^2x+cos^2(120°+x)+cos^2(120°-x)i need this asap. pls me
