82. Meteorology: See the table and answer:
| Year | 1958 | 1964 | 1965 | 1978 | 2002 |
|---|---|---|---|---|---|
| Difference from Base | 0.10°C | −0.17°C | −0.10°C | (1/50)°C | 0.54°C |
(a) Order the five years from coldest to warmest.
(b) In 1946, the average temperature varied by −0.03°C. Between which two years should 1946 fall when the years are ordered?
(a) 1964, 1965, 1978, 1958, 2002
(b) Between 1965 and 1978
Coldest = smallest difference. Order ascending: −0.17 (1964), −0.10 (1965), 0.02 (≈1/50, 1978), 0.10 (1958), 0.54 (2002). −0.03 lies between −0.10 and 0.02, so between 1965 and 1978.
