1. A challenging final exam yields the following results: 10, 15, 20, 20, 25, 25, 25, 30, 30, 100. Which type of measure would best represent the center of the results and what is its value? (2 points)

10, 15, 20, 20, 25, 25, 25, 30, 30, 100

And we want to find the best represent the center of the results and for this case we can see the range given by:

And if we find the mean we got:

But since the range is a large value it's better to use the median as a central measure tendency and we got:

And this would be the best measure of centra tendency for this case

Step-by-step explanation:

For this case we have the following info given:

10, 15, 20, 20, 25, 25, 25, 30, 30, 100

And we want to find the best represent the center of the results and for this case we can see the range given by:

And if we find the mean we got:

But since the range is a large value it's better to use the median as a central measure tendency and we got:

And this would be the best measure of centra tendency for this case

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
