To get the indicated values we re-arrange the set of numbers in ascending order:
<span>2 6 12 8 3 9 14 20
rearranging gives us:
2,3,6,8,9,12,14,20
Minimum-2
First quartile-5.25
Median-8.5
Third quartile-12.50
Maximum-20

Answer:

Given data set is : 2 6 12 8 3 9 14 20

We shall re-arrange the set of numbers in ascending order to get a clear concept:

2 3 6 8 9 12 14 20

1. Minimum: The minimum is the least value of the data set that is 2.

First quartile: The first quartile value is the median for the numbers before the median. 2 3 6 8 the value is \frac{2+3+6+8}{4}= 4.75

Median: The average of the center two numbers. \frac{8+9}{2}=8.5

Third quartile: The third quartile is the same as first but take last 4 values, 9 12 14 20 the value is \frac{9+12+14+20}{4}= 13.75

Maximum: The highest value number in the data set which is 20.

How much of a radioactive kind of thorium will be left after 14,680 years if you start with
babymother [125]

Answer:

8978 grams

Step-by-step explanation:

The equation to find the half-life is:

N(t)= N_{0}e^{-kt}

N(t) = amount after the time <em>t</em>

N_{0} = initial amount of substance

t = time

It is known that after a half-life there will be twice less of a substance than what it intially was. So, we can get a simplified equation that looks like this, in terms of half-lives.

N(t)= N_{0}e^{-\frac{ln(\frac{1}{2}) }{t_{h} } t} or more simply N(t)= N_{0}(\frac{1}{2})^{\frac{1}{t_{h} } }

t_{h} = time of the half-life

We know that N_{0} = 35,912, t = 14,680, and t_{h}=7,340

Plug these into the equation:

N(t) = 35912(\frac{1}{2})^{\frac{14680}{7340} }

Using a calculator we get:

N(t) = 8978

Therefore, after 14,680 years 8,978 grams of thorium will be left.

Hope this helps!! Ask questions if you need!!
