Answer:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.
Answer:48.1897 = 48.2
Step-by-step explanation: cos P= 3.8/5.7
P= cos-1 (3.8/5.7)
P=48.1897 = 48.2
Should be 12.5
19.5 would come out to be greater than 20
17.5 would come out to be 20, but it must be less than
therefore, 12.5 is the answer
Answer:
The correct option is d)

Step-by-step explanation:
Sampling distribution is the process of getting sample through simple random techniques from the population.
