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:
Slope: = 3/10x
y-intercept: = -7/10
Step-by-step explanation:
10y = -3x - 7
y = -3/10x - 7/10
Slope: = 3/10x
y-intercept: = -7/10
Answer:
Option B

Step-by-step explanation:
we know that
The measure of the interior angle is the semi-sum of the arcs comprising it and its opposite
so
![m\angle PTR=\frac{1}{2}[arc\ PR+arc\ QS]](https://tex.z-dn.net/?f=m%5Cangle%20PTR%3D%5Cfrac%7B1%7D%7B2%7D%5Barc%5C%20PR%2Barc%5C%20QS%5D)
substitute the given values
![m\angle PTR=\frac{1}{2}[140^o+106^o]](https://tex.z-dn.net/?f=m%5Cangle%20PTR%3D%5Cfrac%7B1%7D%7B2%7D%5B140%5Eo%2B106%5Eo%5D)
