Answer:
Students level of knowledge is higher in accountancy (Y) compared to statistics (X).
Step-by-step explanation:
The level of knowledge of the students in each subject can be known by comparing the mean score of the subjects.
Marks of the students in statistics (X) are: 63 64 62 32 30 60 47 46 35 28
mean = 
= 
= 46.7
The mean mark of students in statistics (X) is 46.7.
Marks of students in accountancy (Y) are: 68 66 35 42 26 85 44 80 33 72
mean = 
= 
= 55.1
The mean mark of students in accountancy (Y) is 55.1.
It can be inferred that students level of knowledge is higher in accountancy (Y) compared to statistics (X).
Answer:
equation 1: x-5=-8 <=> x=-3
equation 2: x-3=-6 <=> x=-3
equation 3: x.3=-9 <=> x=-3
equation 4: -9 : x=3 <=> x=-3
=> Four equations that have –3 as the solution: x=-3
