Answer:
Probability that a randomly selected student plays sport and is in band = 1/50
Step-by-step explanation:
Total number of students= 1900
Percentage of those that play sport and are in band = 2%
Hence those that play sport and are in band = 2/100 x 1900 = 38 students
Probability that a randomly selected student plays sport and is in band = 38/1900 = 1/50

Answer:
y=8x-23
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Given that the slope is 8, m=8.
subst. m=8 into the equation:
y= 8x +c
To find c, substitute a coordinate.
When x=3, y= 1,
1= 8(3) +c
1= 24 +c
c= 1 -24
c= -23
Thus, the equation of the line is y= 8x -23.
