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
Kiran earns $8.50 per hour.
Let x represent Kiran's pay. He worked 23 hours last week, so his pay would be given by 23x.
Kiran's cousin is paid 30% more. 30% = 30/100 = 0.3. We add this to the x per hour that Kiran is paid:
x + 0.3x = 1.3x
This is multiplied by 27, since Kiran's cousin works 27 hours:
27(1.3x)
This gives us the following equation:
23x + 27(1.3x) = 493.85
23x + 35.1x = 493.85
58.1x = 493.85
Divide both sides by 58.1:
58.1x/58.1 = 493.85/58.1
x = 8.5
Thus Kiran earns 8.50 per hour.
