Dale drew the following box to represent the data set.​

Min 80,  Q1 82, Med. 85.5, Q3 93, Max 100.

90%.

Step-by-step explanation:

Percentage at least 82 =  100 *(100 - 82) / (100-80)

= 90%.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify
