Question

the graph below shows the noon temperatures for five days. (a) what was the least noon temperature for the five days?
square^{circ} mathrm{f}
(b) when did the greatest decrease in noon temperature occur?
sunday to monday
monday to tuesday
tuesday to wednesday
wednesday to thursday

Explanation:

Step1: Find the least temperature

Look at the values on the graph. The temperatures are approximately: Sunday \(76^{\circ}F\), Monday \(77^{\circ}F\), Tuesday \(72^{\circ}F\), Wednesday \(73^{\circ}F\), Thursday \(71^{\circ}F\). The least value is \(71^{\circ}F\).

Step2: Calculate the temperature decreases

• Sunday to Monday: \(77 - 76=1^{\circ}F\) (increase)
• Monday to Tuesday: \(77 - 72 = 5^{\circ}F\) (decrease)
• Tuesday to Wednesday: \(73 - 72=1^{\circ}F\) (increase)
• Wednesday to Thursday: \(73 - 71 = 2^{\circ}F\) (decrease)

The greatest decrease is from Monday to Tuesday.

Answer:

(a) \(71\)
(b) Monday to Tuesday
