Answer: The dependent variable depends on another variable for its value. For example, if y = 2x, setting x = 1 forces y= 2.; setting x = 10, forces y =20. There are no other possibilities for y once x ids chosen. So y is the dependent variable and x is the independent one. You can pick values for the independent variable (x) but no so for the dependent one.

15, 26, 48, 92, 180
26 - 15 = 13
48 - 26 = 22
92 - 48 = 44
180 - 92 = 88
26 ÷ 15 = 1.73
48 ÷ 26 = 1.84
92 ÷ 48 = 1.9167
180 ÷ 92 = 1.95
The recursive formula isn't arithmetic or geometric.
11. rectangle A and the original rectangle are similar because they are the same shape (rectangle A is scaled smaller)
12. the same answer as 11.
13. Rectangle C and rectangle B are not similar because they do not scale together and they are not the same shape.
Answer:
A) Range
Step-by-step explanation:
The original mean would be 4.889. But when you add another 10 to the set, the mean becomes 5.400.
The original mode would be 1, because there are two 1's and only one of every other number. But when adding another 10 the the original set, you end up with two 10's so now the mode is 1 and 10.
The median changes from 5 to 5.5
So the answer has to be range.
