False ....a parameter is something YOU can change, like asking magazines if they are interested in sports, or interested in photography, or something else. So the 12% is a statistic.
Let the unknown number be y.
We can list the equation out by the clues given.
5y + 12 = 52
Then solve this as simple algebra!
Shift +12 to the other side and be - 12
5y = 52-12
5y = 40
Shift x5 to the other side and be ÷5
y = 40 / 5
y = 8
Therfore the unknown number is 8.
R. It is not in the same plane as C, D and E
I think we’re talking about the 15, the smallest number for 15 would be 3. Because 3 x 5 = 15
n² + 1 = 2 5 10 17 26. So the nth term of the sequence is n²+1.
