Given at 11 °C = 95 mL and at 21 <span>°C = 105 mL, then the rate of change of volume per degree rise in temperature is calculated as follows.
(V2 - V1)/(T2 - T1) = (105 mL - 95 mL) / (21</span>°C - 11°C) = 10 mL / 10<span>°C
= 1 mL / </span><span>°C
Therefore, the average rate of change of f(x) between x = 11 to x = 21 is 1 mL/</span><span>°C.</span>
Your Answer Is approximately 0.143
Since you mentioned the fundamental counting principle, I assume you are looking for the total number of possibilities.
If you are picking a month, there are 12 options.
If you are selecting a day of the week, there are 7 options.
If you are doing both, you multiply the two numbers together.
12 x 7 = 84
To get 2 to 5, you multiply 2 by 2.5. do the same to 2/3 to get your answer. 2/3 times 2.5 = 2/3 times 5/2 equals 10/6 or 5/3 cups of sugar (1 and 2/3 cups of sugar) i believe
