Science formulas and statistics
Apply provided science formulas and use statistics such as range, mean, median, and mode.
Formulas are given to you — substitute the values carefully.
°F = °C × 9/5 + 32. For 20 °C: 20 × 1.8 = 36, plus 32 = 68 °F.
Question 1 of 4
A solution's temperature is recorded over 120 seconds: 0 s = 21.1 °C, 30 s = 19.4 °C, 60 s = 18.8 °C, 90 s = 18.3 °C, 120 s = 17.7 °C. Use °F = °C × 9/5 + 32.
What is the temperature of the solution in degrees Fahrenheit at 60 seconds?
