The temperature of the furnace is 1200 and cool at a rate of 15 per minute the temperature of another furnace is 900 and is heat

Hunter-Best [27]

Answer:

After 15 minutes, the temperature of both the furnaces will be same.

Step-by-step explanation:

Let $x$ be the minutes when the temperature of both becomes same.

Now, as per question:

Temperature of the furnace after $x$ minutes that is cooling at the rate of 15 degree per minute is given as:

$T=1200-15x$

Temperature of the furnace after $x$ minutes that is heating at the rate of 5 degree per minute is given as:

$T=900+5x$

Now, equating both the temperatures, we get

$1200-15x=900+5x\\1200-900=15x+5x\\300=20x\\x=\frac{300}{20}=15\ min$

Therefore, after 15 minutes, the temperature of both the furnaces will be same.

110 and 294 are the outliers because their difference in value from other data is large.

<h3>What are outliers?</h3>

An outlier is an observation that lies an abnormal distance from other values in a random sample from a population.

<h3>sample of data</h3>

Given the sample data 110, 196, 197, 199, 205, 208, 209, 210, 210, 294, we need to get the outliers that are an observation that lies an abnormal distance.

From the data, we can see clearly that 110 and 294 are the outliers. Their difference in value from other data is large.
