How to solve standard deviation

How to Calculate Standard Deviation:

Collect your data

Calculate the mean of the data set

Subtract the mean from each number; square result

Add squares together; divide by number of items

Take the square root to find standard deviation

Hope this Helps and works, Good Luck!!!

Step-by-step explanation:

How to Calculate Standard Deviation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
