General Maths External Exam with all Correct & 100%
Verified Answers| Guaranteed to Pass
Correlation Coefficient Measuring Scale ✔Correct Answer-0.90-1.00 very strong
0.70-0.89 strong
0.40-0.69 moderate
0.10-0.39 weak
0.00-0.09 no relationship
What variable goes on the Y axis ✔Correct Answer-response variable
Least Squares Regression Equation ✔Correct Answer-y=a+bx
Calculating Seasonal Indices using average percentage method ✔Correct Answer-1) calculate the
average for each YEAR
2) divide: each value for that year OVER the average for that year
Calculating the distance between two places on the same meridian (e.g. Melb (47s, 153e) BNE (27n,
153e) ✔Correct Answer-D = 111.2 x angular distance
calculate angular distance between two places on
earth on the same parallel of latitude (e.g. Melb (23s, 116e) BNE (23s, 110e) ✔Correct Answer-D =
111.2 x cosθ x angular distance
How many degrees in 1 hour ✔Correct Answer-15 degrees
GMT (Greenwich Mean Time) ✔Correct Answer-The time at the Prime Meridian (0° longitude) in
Greenwich, London. It was used as the world's time standard before UTC
UTC (Coordinated Universal Time) ✔Correct Answer-The modern standard for timekeeping, nearly
identical to GMT but more precise because it's based on atomic clocks. It doesn't adjust for daylight
savings
Compound Interest Recurrence Relation ✔Correct Answer-An+1= rAn, t1=500
simple graph ✔Correct Answer-no loops and no multiple edges
complete graph ✔Correct Answer-each vertex is connected to all other vertices
bipartite graph ✔Correct Answer-split the edges into two groups
planar graph ✔Correct Answer-where no edges cross each other or intersect
connected graph ✔Correct Answer-every pair of vertices can be joined by a path
walk ✔Correct Answer-a sequence of edges from a vertex to another
trail ✔Correct Answer-a walk with no repeated edges
