Question

A newspaper reports the following changes in the temperature of a city over 4 days: 3.24 degrees Celsius, negative 3 over 8 degrees Celsius, −0.15 degrees Celsius, 7 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.

Answer 1

Answer:

• 0.87°C

Step-by-step explanation:

Given data:

• 3.24, -3/8, -0.15, 7/9

Sum up the data and find the average:

• (3.24 - 3/8 - 0.15 + 7/9)/4 ≈ 0.87°C

Answer 2

• Given Temperatures =3.24°C,-3/8°C,-0.15°C,7/9°C
• Total temperatures=4

Average=Sum of Temperatures/No of Temperatures

$\\ \sf\longmapsto \dfrac{3.24-\dfrac{3}{8}-0.15+\dfrac{7}{9}}{4}$

$\\ \sf\longmapsto 0.87°C$
