Answer:

Change in temperature = -9 degrees

Step-by-step explanation:

Given

Start Temperature = 10 deg

Change = 3 deg/hr

Time= 3hr

Required

Change in temperature;

First, the total change in 3 hours has to be solved for. This is done as follows:

Total Change = Change* Time

Total Change = 3 deg/hr * 3 hr

Total Change = 9 deg

From the question, we understand that the temperature dropped.

So,  we can conclude that the temperature changed by -9 degrees;

This means that at the end of the third hour is temperature is 1 degrees

A disc jockey has 20 songs to choose from and can only play 8 in the next half hour. how many different playlists are possible?
motikmotik

This problem is a combination problem since it did not indicate that there is a specified order of songs to be played. The type of combination problem is without repetition. Thus the working equation would be n!/r!(n-r)! wherein n is the total number of songs to choose from and r is the number of songs you can choose at a given time. The answer would be 125970.
