A Celsius thermometer with a range of -10°C cannot be used to determine when the soft ball stage is reached in the candy mixture.
Temperature is most commonly measured with a thermometer that has two different scales: Fahrenheit and Celsius. Water freezes at 0°C and boils at 100°C on the Celsius scale and freezes at 32°F and boils at 212°F on the Fahrenheit scale.
Temperature of 236°F corresponds to 113.3°C. Now a Celsius scale has a maximum of 100°C on the thermometer. Hence a Celsius thermometer cannot be used to measure a temperature that corresponds to 236°F.

Answer:
9.1 mg/dL
Explanation:
A normal distribution is symmetrical, the area below the curve of negative Z-scores is equal to the area below the curve of positive Z-scores, Z measures the statistic observed and the parameter of the population.
And it is:
Z = (x - μ)/σ
where μ is the mean (9.5 mg/dL), x is the borderline, and σ is the standard deviation, which is 0.3 mg/dL.
The Z-score can be calculated in excel by the function =NORMSINV, and the factor will be the percente considered (10% = 0.1)
NORMSINV(0.1) = -1.28155
So,
-1.28155 = (x - 9.5)/0.3
x - 9.5 = -0.384465
x = 9.1 mg/dL

<em>What type of system is best used to observe conservation of matter because all of the mass stays in one place?</em>
<em />
A closed system Would be The Correct Answer!
Explanation:
In a closed system, matter does not enter or leave And it Says In one place.
Therefore, making A Closed System the Correct Answer.
