The high temperatures for five days in Alaska are given in the table below. Which statement is true regarding the daily temperatures?

\begin{tabular}{|c|c|c|c|c|}
\hline Mon & Tues & Weds & Thurs & Fri \\
\hline[tex]$-6^{\circ} F$[/tex] & [tex]$-3^{\circ} F$[/tex] & [tex]$2^{\circ} F$[/tex] & [tex]$-8^{\circ} F$[/tex] & [tex]$-11^{\circ} F$[/tex] \\
\hline
\end{tabular}

A. Wednesday < Thursday
B. Monday < Friday
C. Tuesday > Thursday
D. Thursday > Monday



Answer :

To determine which statement is true regarding the given daily temperatures in Alaska, let's analyze each statement step by step:

Given temperatures:
- Monday: [tex]\(-6^{\circ} F\)[/tex]
- Tuesday: [tex]\(-3^{\circ} F\)[/tex]
- Wednesday: [tex]\(2^{\circ} F\)[/tex]
- Thursday: [tex]\(-8^{\circ} F\)[/tex]
- Friday: [tex]\(-11^{\circ} F\)[/tex]

Statement A: Wednesday < Thursday

To verify this statement, we compare the temperatures on Wednesday and Thursday:
- Wednesday: [tex]\(2^{\circ} F\)[/tex]
- Thursday: [tex]\(-8^{\circ} F\)[/tex]

[tex]\(2^{\circ} F\)[/tex] is greater than [tex]\(-8^{\circ} F\)[/tex], hence Wednesday's temperature is not less than Thursday's temperature. Therefore, Statement A is false.

Statement B: Monday < Friday

To verify this statement, we compare the temperatures on Monday and Friday:
- Monday: [tex]\(-6^{\circ} F\)[/tex]
- Friday: [tex]\(-11^{\circ} F\)[/tex]

[tex]\(-6^{\circ} F\)[/tex] is greater than [tex]\(-11^{\circ} F\)[/tex], hence Monday's temperature is not less than Friday's temperature. Therefore, Statement B is false.

Statement C: Tuesday > Thursday

To verify this statement, we compare the temperatures on Tuesday and Thursday:
- Tuesday: [tex]\(-3^{\circ} F\)[/tex]
- Thursday: [tex]\(-8^{\circ} F\)[/tex]

[tex]\(-3^{\circ} F\)[/tex] is greater than [tex]\(-8^{\circ} F\)[/tex], hence Tuesday's temperature is indeed greater than Thursday's temperature. Therefore, Statement C is true.

Statement D: Thursday > Monday

To verify this statement, we compare the temperatures on Thursday and Monday:
- Thursday: [tex]\(-8^{\circ} F\)[/tex]
- Monday: [tex]\(-6^{\circ} F\)[/tex]

[tex]\(-8^{\circ} F\)[/tex] is less than [tex]\(-6^{\circ} F\)[/tex], hence Thursday's temperature is not greater than Monday's temperature. Therefore, Statement D is false.

Summarizing our analysis, the only true statement is:
- Statement C: Tuesday > Thursday

Thus, the correct answer is that statement C is true.
