Lori Cook has developed the following forecasting model: ModifyingAbove y with caret = 36.0 + 4.50x, where ModifyingAbove y with caret = demand for Kool Air conditioners and x = the outside temperature (degrees Fahrenheit) a) When the temperature outside is 70degrees F, demand forecast = ??? air conditioners(enter your response as an integer).

351 unit

Explanation:

From Lori cook's model, we have that

y=36.0+4.5x

Where y is the demand for cool air conditional and

x is the outside temperature (degrees Fahrenheit)

This relationship can be used to derive the demand for cool air conditional when some outside temperatures are known.

For x= 70⁰F

y=36.0 +4.5(70)

y= 36.0+ 315

y= 351.0 or 351 units demand for cool air conditional

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
