Help with this I don't know how to solve plz greatly appreciate

cos∅ = 16√481/481

Step-by-step explanation:

Pythagorean Theorem: a² + b² = c²

cos∅ = adjacent/hypotenuse

tan∅ = opposite/adjacent

Step 1: Find hypotenuse

15² + 16² = c²

c = √481

Step 2: Find cos∅

cos∅ = 16/√481

cos∅ = 16√481/481

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
