Question

A newspaper reports the following changes in the temperature of a city over 4 days:

1.34 degrees Celsius, negative 5 over 7 degrees Celsius, −0.75 degrees Celsius, 4 over 9 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. (10 points)

Answer 1

So to find the average, let's start off by adding all degrees together and dividing by the amount of values, 4.

\(\dfrac{1.34+ -\dfrac{5}{7}+-0.75+\dfrac{4}{9}}{4}\) = ?

When added all together and divided, gives you roughly \(-8.50\).

Answer 2

thats it?

Answer 3

Assuming you gave the correct values, yeah.

Answer 4

Yeah.
