Answer: 16
Step-by-step explanation:
Total number of laptops ordered= 650
Number of laptops tested= 40
Number of laptops that takes more than 30 seconds to start up= 1
To get the number of laptops that will take 30 seconds to start in the whole shipment goes thus:
Let the number of laptops that will take more than 30 seconds be represented by y.
1 : 40 = y : 650
1/40 = y/650
Cross multiply
40y = 650
y= 650/40
y= 16.25 which approximately gives 16.
There are expected to be 26 laptops that takes more than 30 seconds to start.
