Answer:

the coordinates of the centroid of the triangle with the vertices A(-6,8), B(-3,1),andC(0,3).

={(-6-3-0)/3,(8+1+3)/3}=(-<em>3</em><em>,</em><em>4</em><em>)</em>

Answer:

<em>( - 3, 4 )  </em>

Step-by-step explanation:

The centroid of a triangle is the intersection of the three medians of the triangle.

A ( - 6, 8 )

C ( 0, 3 )

Coordinates of the midpoint of AC are D( - 3, 5.5 )

Median BD is x = - 3

Coordinates of midpoint of BC are E( - 1.5, 2 )

m_{AE} = - \frac{4}{3}

Equation of median AE is y = - \frac{4}{3} x

Solve system of equations:

y = - \frac{4}{3} x and x = - 3

<em>( - 3, 4 ) are coordinates of the centroid of the Δ ABC </em>

Oksi-84 [34.3K]
The histogram is especially useful in comparing mean and median values of a variable. We have that 5.5+6+7+10+7.5+8+9.5+9+8.5+8+7+7.5+6+6.5+5.5=111.5 Since there are 15 values, their mean is 111.5/15=7.43 which is very close to the mean. We also have that 7 onservations are lower than 7.4 while 8 are bigger than 7.4; hence, the diagram is rather balanced and not left-skewed. We cannot tell immediately which one is larger since the values are too close. Any such random process can usually be approximated to a greater or smaller degree by a normal curve; the more points, the better. The histogram shows this (it is kind of a discrete normal curve); all points except 4 will be in this interval of bars.

In the diagram ABC is equal to DEC what is the value of x?
Hatshy [7]
\begin{gathered} \frac{25}{5}=\frac{18-x}{x} \\ 25x=(18-x)\times5 \\ 25x=90-5x \\ 25x+5x=90-5x+5x \\ 30x=90 \\ \frac{30x}{30}=\frac{90}{30} \\ x=3 \end{gathered}
