Correct result:
a = 100
c = 800
t = 300
Solution:
6a + 5t + 4c = 5300
a + t + c = 1200
(8/3)t = c
6•a + 5•t + 4•c = 5300
a + t + c = 1200
(8/3)•t = c
6a+4c+5t = 5300
a+c+t = 1200
3c-8t = 0
a = 100
c = 800
t = 300
Number of exams per semester = 5
Average of first four exams = 90
Therefore,
Total of first four exams = 90*4 = 360 marks
Based on 5 exams,
Average = 360/5 = 72
is an irrational number i.e. it cannot be written in the form of
where p and q are integers and q is never equal to 0.
By multiples of
, we can write like:
1
=
= 3.14
2
= 2*3.14 = 6.28
3
= 3*3.14 = 9.42
In the same way, any integer n when multiplied by
, is a multiple of
The slope of the line is 2
The line which is having same y intercept as the line which passes through points (-4,0) and (0,3) is y=2x+3.
Given Points through which the line passes through are (-4,0) and (0,3)
We have to find the equation whose y intercept is equal to the y intercept of the line whose points given above.
First of all we have to find the y intercept of the line which passes through (-4,0) and (0,3). Equation of line is :
y-y1=(y2-y1)/(x2-x1)*(x-x1)
y-0=(3-0)/(0+4) *(x+4)
y=3/4(x+4)
y -intercept exists where x=0
put x=0
y=3
So the options are:
By putting the value of x in all options we will find
y=-4
y=-3
y=3
y=4
So the third option is correct.
Hence the line whose y-intercept matched with the given line is y=2x+3.
