What is the median for the boys plot?

ollegr [7]

Answer:

Step-by-step explanation:

first you put the numbers in order from least to greatest

1,1,1,1,2,2,2,4,12,13,15,15,15,16,16

next find the middle number(s)

1,1,1,1,2,2,2,4,12,13,15,15,15,16,16

the middle number is your median

*if you have 2 middle numbers just add the then divide it by 2 to find the median

Find the midsegment of triangle ABC so that it is parallel to side BC and label it as segment EG on the graph.

Lelechka [254]

Answer:

Coordinate of E:(-2,3) Coordinate of G: (2.5,1.5)

Parallel: slopes both = -1/3

1/2 segment: EG length= 3 BC length=6: This is the only one I'm not sure about.

I will show the work for both the problems down below.

Step-by-step explanation:

Finding coordinates:

1+(-5)/2=-2 5+1/2=3

(-2,3)

1+4/2= 2.5 5+(-2)/2= 1.5

(2.5,1.5)

Show work verifying the EG and BC are parallel:

You can do this by finding the slope

Slop formula (y2-y1)/(x2-x1)

(1.5-3)/(2.5-(-2))

Then simplify

-1.5/2/5= -1/3 which i your slope. You use the same formula and follow thee same steps for the points of BC and both will come up as -1/4 meaning they are parallel.

Show work verifying that EG and BC are parallel:

Use distance formula to find how long each line is

√(x2-x1)^2+(y2-y1)^2

√(2.5-(-2)^2)+(1.5-3)^2

Simplify

√4.5+(1.5)=3

Do the same thing with BC and you will get 6

Write y+4=2/3(x+7) ...?

iragen [17]

y+4=2/3(x+7)

Multiplying both sides by the denominator which is 3:
3(y+4) = 3(2/3) * (x+7)
3y+12=2x+14

Subtract 3y:
12 = 2x - 3y + 14

Subtract 14
-2 = 2x - 3y

The difference between the solutions to the equation x2 =a is 30 what is a ?

Mademuasel [1]

Given equation is $x^2 = a$

In general solution of $x^2 = b$ is $x = + \sqrt{b}$ and $x = - \sqrt{b}$

So the solution of given equation is $x = + \sqrt{a}$ and $x = - \sqrt{a}$

Now difference between them is 30.
So we can write
$\sqrt{a} - (- \sqrt{a}) = 30$
$\sqrt{a} + \sqrt{a} = 30$
$2 \sqrt{a} = 30$
$\sqrt{a} = 15$

On squaring both side
$( \sqrt{a})^2 = (15)^2$
$a = 225$
