These plots show the number of kilometers a group of students at Middleton Middle School and at Westwood Middle School travel to

vitfil [10]

Answer:

Middleton only

Step-by-step explanation:

Sometimes, in a data set, there is a number that is much larger or much smaller than the others generally tend to be. These numbers that are far away from the average are known as outliers

The data set for the students at Middleton Middle School:

1 2 2 2 2 3 3 3 3 3 4 4 4 4 5 5 5 5 6 9

We can note that most of data is between 1 and 6, the gap between them is 0 or 1, but there is one of the data which is 9, the gap between 9 and 6 is 3

So, 9 would be considered an outlier.

So, The shapes of plots shows an outlier is Middleton only

The data set for the students at Westwood Middle School:

2 2 2 2 3 3 3 3 3 4 4 4 4 5 5 5 5 6 6 6

We can note that all of data is between 2 and 6, the gap between them is 0 or 1

So, There is no outlier for the set of data.

I need to know q2 please help

Given that the half-life of uranium is $4.5\times10^9$ years, you know that after that amount of time you're left with half as much uranium as what you start with:

$\dfrac12=e^{-k\times4.5\times10^9}$

Solve this equation for $k$ to find the decay rate.

$\dfrac12=e^{-k\times4.5\times10^9}$
$\implies \ln\dfrac12=\ln e^{-k\times4.5\times10^9}$
$\implies -\ln2=-k\times4.5\times10^9\ln e$
$\implies k=\dfrac{\ln2}{4.5}\times10^{-9}$

Now you're looking to find the time it takes for the substance to decay to one eighth of its original amount, which is the time $t$ such that

$\dfrac18=e^{-kt}$
$\implies\ln\dfrac18=\ln e^{-kt}$
$\implies-\ln8=-kt\ln e$
$\implies t=\dfrac{\ln8}k=\dfrac{\ln8}{\frac{\ln2}{4.5}\times10^{-9}}=\dfrac{\log_28}{4.5}\times10^9\approx0.66\times10^9$
