a chef knows that ground beef used for hamburger is safe to eat once it reaches 160 degrees fahrenheit. for optimized taste and safety, he will not allow a hamburger cooked to a temperature under 160 degrees or over 170 degrees to be served. which graph represents the conditions under which the chef will not allow the hamburger to be served?\n156 160 164 168 172\n156 160 164 168 172\n156 160 164 168 172\n156 160 164 168 172

Answer

Answer:

First option (with open circles at 160 and 170, shading left of 160 and right of 170)

Explanation:

Step 1: Define the temperature conditions

The chef does not allow temperatures under 160°F or over 170°F: ( T < 160 ) or ( T > 170 ).

Step 2: Represent inequalities on a number line

Use open circles at 160 and 170 (not included) with shading to the left of 160 and right of 170.

Step 3: Match the correct graph

The first option depicts open circles at 160/170 with shaded regions for ( T < 160 ) and ( T > 170 ), which matches the conditions.
