Step-by-step explanation:

5n-2

5(4) - 2

20-2=18

A= 18

5n - 2 =48

5n=48+2

5n=50

Lamar is writing a coordinate proof to show that a segment from the midpoint of the hypotenuse of a right triangle to the opposi

Zanzabum

1. N is a midpoint of the segment KL, then N has coordinates

$\left(\dfrac{x_K+x_L}{2},\dfrac{y_K+y_L}{2} \right) =\left(\dfrac{0+2a}{2},\dfrac{2b+0}{2} \right) =(a,b).$

2. To find the area of △KNM, the length of the base MK is 2b, and the length of the height is a. So an expression for the area of △KNM is

$A_{KMN}=\dfrac{1}{2}\cdot \text{base}\cdot \text{height}=\dfrac{1}{2}\cdot 2b\cdot a=ab.$

3. To find the area of △MNL, the length of the base ML is 2a and the length of the height is b. So an expression for the area of △MNL is

$A_{MNL}=\dfrac{1}{2}\cdot \text{base}\cdot \text{height}=\dfrac{1}{2}\cdot 2a\cdot b=ab.$

4. Comparing the expressions for the areas you have that the area $A_{KMN}$ is equal to the area $A_{MNL}$ . This means that the segment from the midpoint of the hypotenuse of a right triangle to the opposite vertex forms two triangles with equal areas.

Kate reads books that were 240, 450, 240, 160, 165, 170, 180 pages long. What are the mean median and mode and which one describ

ser-zykov [4K]

Order set...{160,165,170,240,240,450}

The "mean" is the arithmetic average of the elements...

mean=(160+165+170+240+240+450)/6=237.5

The "median" if the set has an odd number of terms is the middle term, if the set has an even number of terms, it is the average of the middle two terms.

In this case the number of elements is even and the middle two terms are 170 and 240 so:

median=(170+240)/2=205

The "mode" is the term which appears the most in the set, so in this case:

mode=240
