a horse’s body tempera T is considered to be normal if it is within at least o.9 degrees F of 99.9 degrees F Find the range of normal body temperatures for a horse.
Since the horse’s temperature T is normal within 0.9 degrees Fahrenheit, you simply need to find the greatest and least possible values. After this, you can subtract the lowest from the highest to get the range.
99.9 + 0.9 = 100.8
99.9 - 0.9 = 99
100.8 - 99 = 1.8
Range = 1.8 degrees Fahrenheit
