Answer:
240 - 5x and the candle will be at 0 mm in 48 seconds
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
A 240 mm candle is burning and shrinks in height 5mm per second
<em>240 - 5x</em>
<u>Step 2: If needed solve for x</u>
240 - 5x - 240 = 0 - 240
-5x / -5 = -240 / -5
<em>x = 48</em>
Answer: 240 - 5x and the candle will be at 0 mm in 48 seconds
Graph Below: (0, 240) shows the initial start and (48, 0) shows the ending point

Answer:
mean: 5.6 ; median: 5
Step-by-step explanation:
first order them:
2, 2, 3, 4, 4, 5, 5, 5, 6, 6, 7, 9, 10, 11
now we can see that the median is 5 since it's in the middle
and the mean is adding all and dividing by how many numbers we have (AKA 14) so 2+2+3+4+4+5+5+5+6+6+7+9+10+11 = 79 and now we divide 79 by 14 which is:
5.64285714
The answer is $11.25 because 110-8.75÷9

In this question:
Proportion .3852
0.3852*100% = 38.52%
The percentage score is 38.52%
