In order to covert temperature from Kelvin to Celsius scale, we have to subtract 273 from the given value because K - 273 = °C
(a) 293 K - 273 = 20°C
(b) 470K - 273 = 197°C
Length (in hours) | Number of lamps |
|---|---|
300 − 400 | 14 |
400 − 500 | 56 |
500 − 600 | 60 |
600 − 700 | 86 |
700 − 800 | 74 |
800 − 900 | 62 |
900 − 1000 | 48 |
(i) Represent the given information with the help of a histogram.
(ii) How many lamps have a lifetime of more than 700 hours?
