X +9 x +3 (x+9)(x+2) - 8(x+3)
------ - --------- = ---------------------------
8 x +2 8(x+2)
do you think it in this way or more simplified ?
(x - 1)2 - 4(X + 1) + 2 = 0
2x - 2 - 4x - 4 + 2 = 0
(2x - 4x) - 4 = 0
-2x = 4
x = 4/-2
x = -2
the diameter of two tortillas would be 6, since 12+12=24. the diameter of 24 is 6, so that would be your answer....
Systematic sampling is a type of probability sampling method in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval. This interval, called the sampling interval, is calculated by dividing the population size by the desired sample size.
