A.) Determine the value z* that separates the largest 10% of all z values from the others. b.) Determine the value of -z* and z* that separate the middle 86% of all z value

Def is a scalene triangle

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
