Which measure of central tendency is MOST EASILY affected by outliers

Mathematics
1 answer:
Serjik [45]3 years ago
5 0
The average can be easily affected by outliers because an outlier can bring the average much higher or lower depending on the value. For example, if this was the data set

0,50,51,52
 the average would be 38.25

But without the 0, the average would be 51.<span />

Answer:

y = 0.55 or 5 / 9

Step-by-step explanation:

here's the solution :-

=》y + 7 = 19y - 3

=》7 + 3 = 19y - y

=》18y = 10

=》y = 10 ÷ 18

=》y = 5 ÷ 9

In 2003 a town’s population was 1431. By 2007 the population had grown to 2134. Assume the population is changing linearly.How m
sergiy2304 [10]

We will have the following:

First, we will have that the population change by:

\Delta P=2134-1431\Rightarrow\Delta P=703

So, the population changed by 703 people.

It took the follwoing number of years to change from 1431 to 2134:

\Delta y=2007-2003\Rightarrow\Delta y=4

So, it took 4 years to changes from 1431 to 2134.

m=\frac{2134-1431}{2007-2003}\Rightarrow m=175.75

The average population growth per year is of 175.75 people per year.

The population in 2000 would have been:

P_{2000}=\frac{2000\cdot1431}{2003}\Rightarrow P_{2000}=1428.856715\ldots

\Rightarrow P_{2000}\approx1429

So, the population in 2000 would have been approximately 1429 people.

We will have that the equation for the population would be:

P=(\frac{2134-1431}{2007-2003})t+1429\Rightarrow P=\frac{703}{4}t+1429

So, the equation would be:

P=175.75t+1429

Now, we predict the number of people of the town in 2014:

P_{2014}=175.75(14)+1429\Rightarrow P_{2014}=3889.5

\Rightarrow P_{2014}\approx3890

So, there will be approximately 3890 people of the town in 2014.

Solve this system of linear equations. Separate
Tems11 [23]

Answer:

(-7,-4)

Step-by-step explanation:

There are 2 different ways to solve a system of equations and the one I'm going to show you will work for all systems.  To start we will solve one of the equations for either X or Y it doesn't matter which one so I will choose the second one.  Divide both sides by negative 4 and you will have the solved equation.  x=1+2y Now we know what x equals so we can plug "1+2y" into the other equation where we see an X and we will get -8(1+2y)=24-8y and since we only have one variable now we can solve to get what Y is.  The first step is distributing -8-16y=24-8y now lets put the Y's together on one side and the numbers together on the other -32=8y and just divide both sides by 8 to get the value of Y -4=y  Now that we have Y we can plug -4 into either equation as Y to get the value of X I will use the second equation.  -4x=-4-8(-4) and solve for X -4x=-4+32  -4x=28  x=-7 So now we have x and y and we can write it as out solution (-7, -4)

I hope this helps and please don't hesitate to ask if there is anything still unclear!
