Answer:
12
Step-by-step explanation:
The range is the difference from the greatest data point and the least data point. By looking at the box plot, the lowest value would be 0 while the highest would be 12. You use the definition of range to find it:
12 - 0 = 12
F(2)=4(2)-3=5
f(6)=4(6)-3=21
X is a variable to find it you need to isolate it(get it by itself)
Answer:
x=-12
Step-by-step explanation:
because 8-12 geta you -4
Answer: The answer is (D)
