Ответ:
T > -10 and T < -16
sample value at which of the cooling would turn on = -9
sample value of which of the cooling would turn off = -17
Step-by-step explanation:
Let the temperature be denoted by T
A freezer is set to turn on and start cooling if the temperature rises above -10 Celsius
T > -10 first inequality when the temperature is above -10
the cooling turns off when the freezer has reached the temperature of-16 Celsius
T < -16 inequality for switching off the freezer
From these two inequalities the acceptable temperatures are between -10 and -16
sample value at which of the cooling would turn on will be any value greater than -10 and -9 will be a good example.
sample value of which of the cooling would turn off would be any value smaller than -16 and -17 will be a good example.
