Question

the table to answer the questions.
checkpoint\taltitude
\t\t(feet above sea level)
1\t521
2\t2370
3\t-175
4\t3417
5\t-62
(a) compare the altitudes of checkpoint 3 and checkpoint 5 using <, >, or =.
-175 square -62
what is the meaning of the inequality above?
checkpoint 3 is higher than checkpoint 5.
checkpoint 3 is lower than checkpoint 5.
(b) compare the altitudes of checkpoint 1 and checkpoint 4 using <, >, or =.
521 square 3417
what is the meaning of the inequality above?
checkpoint 1 is higher than checkpoint 4.
checkpoint 1 is lower than checkpoint 4.

Explanation:

Step1: Analyze Checkpoint 1 and 4 altitudes

Checkpoint 1 altitude: \( 521 \)
Checkpoint 4 altitude: \( \frac{3417}{4} = 854.25 \)? Wait, no, wait the table: Checkpoint 1 is 521, Checkpoint 4 is 3417? Wait no, the table: Checkpoint 1: 521, Checkpoint 2:2370, Checkpoint3:-175, Checkpoint4:3417, Checkpoint5:-62. Wait, no, the user's table:

Checkpoint | Altitude (feet above sea level)
--- | ---
1 | 521
2 | 2370
3 | -175
4 | 3417
5 | -62

So (b) Compare Checkpoint 1 (521) and Checkpoint 4 (3417) using <, >, or =.

Step2: Compare 521 and 3417

Since 521 is less than 3417, so \( 521 < 3417 \).

Answer:

\( 521 < 3417 \) (so the symbol is <)
