Answer:
Step-by-step explanation:
2(4z+3+3z)=174

7z=87-3=84
z=84/7=12
WX=3z=3×12=36 units
I do not know the values of the numbers so I cannot give u a direct answer.
1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21
Q1 (quartile 1) = take the 5th and 6th number and divide it by 2
Q2 (quartile 2, median) = the 11th number
