A newspaper reports the following changes in the temperature of a city over 4 days: 2.64 degrees Celsius, negative 2 over 9 degrees Celsius, −0.35 degrees Celsius, 5 over 8 degrees Celsius

Write an expression to show the average daily change in the temperature of the city.

Write the steps to solve the expression. Round your answer to the nearest hundredth.

  a) (2.64 -2/9 -0.35 +5/8)/4

  b) perform the sum, then the division, then round as needed

Step-by-step explanation:

a) The average of a number of items is their sum, divided by the number of items. Here, we want the average of 4 changes, so we compute it as the sum of the changes divided by 4.

  average change = (2.64 -2/9 -0.35 +5/8)/4

b) My calculator is capable of adding these numbers directly. For a result rounded to the nearest hundredth, it can be a good idea to represent the fractions using at least 3 decimal digits.

So, the steps would be ...

Performing these steps, we get ...

  average change = (2.64 -0.222 -0.35 +0.625)/4 = 2.693/4

  average change ≈ 0.67 . . . degrees

The average daily temperature change of a city was 0.67 degrees.

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
