Question

A. Write an expression to represent the average daily change in temperature over four days, given the changes: 153/100°C, -4/7°C, -13/20°C, 5/8°C.

b. Calculate the average daily change in temperature. Round your answer to the nearest hundredth.

Answer 1

The average daily change in temperature over four days is approximately -0.0825°C.

Step-by-step explanation:

To find the average daily change in temperature over the four days, we need to add up all the changes and divide by 4. The expression is:

(153/100 + -4/7 + -13/20 + 5/8)/4

Simplifying the expression, we get:

(763/500 + -320/700 + -247/400 + 125/200)/4

Combining the fractions, we have:

(3052 - 1600 - 1735 + 1250)/4

Calculating this expression, we get:

-33/400

The average daily change in temperature is approximately -0.0825°C.
