Show your work and steps. If your answer is not an integer, explain what two integers your answer is between.





What is the mean change in the forecasted low temperatures over the next 7 days? Remember, this can be found by averaging the values in the Difference column for the low temperatures. If your answer is not an integer, explain what two integers your answer is between.

Answer 1

you have to subtract all of the negatives from high temp and then tur it into a fraction ex: -4 + (-2) + (-1) + (-2) + 1 + 3 =15 -15/6 =-2 the answer is -2

and simplify the fraction

now you do that for both of them and ur done :)

87+87+81+86+89+83+89= 602. Divided by 7 because that’s how many numbers there were is 86 and that is your mean/average.
