Answer: C. Stratification
Step-by-step explanation: There are diverse samping techniques employed for statistical purposes depending on the tipe and nature of data available or other factors. When a data population is sampled in sects such that the entire data is divided into a equals groups at a fixed intervals based on a certain criteria, it is called stratified sampling. Here, data is divided into strata, with each stratum containing a fixed amount of samples with each partition taking place at regular interval. In the scenario stratification process is employed by sampling at a fixed and regular interval, however, the random nature of the data is not violated.
<span>1x + 2x = 15
3x = 15
3x/3 = 15/3
x = 5
Gemma = 1x, Zak = 2x therefore Gemma = 5 and Zak = 10</span>
The answer to that question is
C. transitive
The post is on the first quadrant at the coordinates (3, 2).
Step-by-step explanation:
Step 1; First we need to determine which quadrant the point (-3, 2) is on. The coordinate has a negative value of x which denotes it could be located on either the second or third quadrant. The y coordinate has a positive value so out of the second and third quadrant, it is located in the second quadrant.
Step 2; The fence post is reflected over the y-axis which means the coordinate values remain the same but the symbols are in accordance with the first quadrant. In the first quadrant, both x coordinates and the y coordinates are positive. So the co-ordinate for the reflected fence post is (3, 2).
