Five whole numbers are written in order
xenn [34]

Answer:

The values of x and y is given by the equation 4x-y=20+y.

Step-by-step explanation:

Given : Five whole numbers are written in order  4 6 x y 10 , the mean and median of the five numbers are the same.

To find : The values of x and y ?

Solution :

Observations 4, 6, x, y, 10.

Mean is summation of observation divided by number of observation.

i.e. m=\frac{\sum x_n}{n}

m=\frac{4+6+x+y+10}{5}

m=\frac{20+x+y}{5}

Median is middle term of observations.

Median of odd terms M=\frac{n+1}{2}^{th} term

M=\frac{5+1}{2}^{th}

M=3^{rd} term

M=x

The mean and median of the five numbers are the same.

i.e. \frac{20+x+y}{5}=x

20+x+y=5x

4x-y=20+y

The values of x and y is given by the equation 4x-y=20+y.

weqwewe [10]

Answer:

D. SAS

Step-by-step explanation:

Given: ΔABC

Bisecting <ABC to create point D implies that BD is a common side to  ΔABD and ΔCBD.

Also,

m<ABD = m<CBD (angle bisector)

BA = BC (given property of the isosceles triangle)

Therefore,

ΔABD ≅ ΔCBD (Side Angle Side)

The reason for statement 5 in this proof is that ΔABD ≅ ΔCBD by SAS (Side-Angle-Side) relations of the congruent triangles.
