Fatima conducted an experiment where she asked people to estimate the temperature of glasses of water. she recorded how far the estimates were from the actual temperatures, using positive values for guesses that were too high and negative values for guesses that were too low. her results are in the table below.

what is the mean value in fatima's results in degrees celcius?

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

step-by-step explanation:

its 512 because parenthesis and to the 2nd power is 512 so it will be 512

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
