Explanation:

Step1: Analyze question 1

The stock market lost 15 points. Loss is represented by a negative integer.

Step2: Analyze question 2

A football team gained 27 yards. Gain is represented by a positive integer.

Step3: Analyze question 3

Mr. Voss decreased his speed. Decrease is represented by a negative integer.

Step4: Analyze question 4

The water temperature dropped. Drop is represented by a negative integer.

Step5: Analyze question 5

The opposite of 18 is -18. The absolute value of 18 is \(|18| = 18\).

Step6: Analyze question 6

The opposite of -24 is 24. The absolute value of -24 is \(|-24|=24\).

Step7: Analyze question 7

First calculate \(8 - 8=0\). The opposite of 0 is 0. The absolute value of 0 is \(|0| = 0\).

Step8: Analyze question 8

On the number line, -16 is to the left of -10. So -16 is smaller.

Step9: Analyze question 9

Negative numbers are less than positive numbers. So -128 is smaller.

Step10: Analyze question 10

First calculate \(|-16| = 16\). Then compare 12 and 16. 12 is smaller.

Step11: Analyze question 11

\(92+(-72)=92 - 72=20\).

Step12: Analyze question 12

\(-2+(-6)=-(2 + 6)=-8\).

Step13: Analyze question 13

\(6\times(-11)=-(6\times11)=-66\).

Step14: Analyze question 14

\((-10)\times(-28)=10\times28 = 280\) (product of two negative numbers is positive).
