Which of the following statements describes an application of the 80-20 rule in the field of sport marketing? Eighty percent of team revenue should come from tickets, and 20 percent should come from sponsorship. Eighty percent of sport event attendees should purchase their tickets before the event, and 20 percent will be walk-up buyers. Eighty percent of market consumption comes from 20 percent of the consumers. Eighty percent of the marketing budget should be spent on targeted efforts, and 20 percent should be spent on mass-marketing initiatives.

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

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.'

the correct option is c
