Answer:
0
Step-by-step explanation:
Well average means mean so we have to find the mean of the numbers in the data set. Our numbers are -12,12,-4, and finally 4. When we add all of them up we get 0 and we have to divide 0 by the 4 thermoters and your answer is 0. if this is confusing just leave a comment and ill try to explain better

(It's best to memorize the 30-60-90 and the 45-45-90 triangles during trigonometry. It helps a lot.)
Hope this helps!

Answer:
B(75) represents the percent of battery full after 75 minutes of game play
Step-by-step explanation:
Let m represent the number of minutes of game play. If 1% of the battery is drained every five minutes of game play, then after m minutes of game play
was drained.
The battery starts off at 80% full. After m minutes the battery will have

percent full.
When
minutes, then

-3x + 5 > 17 |subtract 5 from both sides
-3x > 12 |change the signs
3x < -12 |divide both sides by 3
<h3>x < -4</h3>
