1. What are the mean, median, mode, and range of the data set 18, 19, 20, 21, 23, 26.26.26? a. mean = 22.4, median = 22: mode = 26 b. mean = 22.4: mellan 26 mode = 22 c. mean = 26: median = 22.4: mode = 24 d. mean = 23.4: median 22: mode = 26 ​

a) is right

Step-by-step explanation: Mode is 26 because there are more numbers 26 than others. Median is average of two numbers in middle because there are even amount of numbers, also 0.5·(21+23)= 22. Average is 22.4

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

translate k to n and reflect across the line containing jk.
