Question

At midnight, the temperature in a city was 5 degrees Celsius. The temperature was dropping at a steady rate of 2 degrees Celsius per hour. Write an inequality that represents h, the number of hours past midnight, when the temperature was colder than -7 degrees Celsius. *

Answer 1

:Mode

You can't use mean because there is no number

You can't also use median because it makes no sense at all

Answer 2

An inequality that represents h, the number of hours past midnight, when the temperature was colder than -7 degrees Celsius is 5 - 2t < -7.

In Mathematics, an inequality is a relation that compares two or more numbers and variables in an algebraic equation based on any of the following inequality symbols:

• Less than or equal to (≤).
• Greater than (>).
• Greater than or equal to (≥).
• Less than (<).

Based on the information provided above, we can logically deduce the following parameters;

The temperature at midnight is 5 degrees Celsius,

The rate of change in temperature per hour is 2 degrees.

The variable t represents the hours past midnight.

In this context, an inequality that represents h, the number of hours past midnight, when the temperature was colder than -7 degrees Celsius can be written as follows;

5 - 2t < -7.
