Answer: ( 5, 2 )
Step-by-step explanation:
If the original image is Q ( -7, -6 ) and you are looking for Q' ( A translated version of the original image )
If the translation is ( x, y ) --> ( x + 12, y + 8 )
If coordinates are ( x , y ) and the original image is ( - 7, -6 )
Then that means:
x = -7
y = -6
Use the original coordinates you have and add them with the translation given to you
( - 7 + 12 ) and ( -6 + 8 )
The coordinates of Q' is ( 5, 2 )
Hope this helps!!
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:
4% per annum
Step-by-step explanation:
Recall :
Simple interest = principal * rate * time
Given that :
Time = 3 ; simple interest = 84 ; principal = 700
84 = 700 * rate * 3
84 = 2100 * rate
Rate = 84 /2100
= 0.04
= 0.04 * 100% = 4% per annum
