Which two triangles are congruent? Complete the congruence statement.

anygoal [31]

Answer:

△ VUW = △ KJI

Step-by-step explanation:

In △ VUW, △ KJI,

UW = JI ( Sides are equal )

∠ VUW = ∠ KJI ( From the diagram )

∠ UWV = ∠ KIJ ( From the diagram )

By ASA rule of congruency,

△ VUW is congruent to △ KJI.

What are the mean and mode of the following data set? 59 16 57 46 58 21 36 41 23 64 20 66 40 51 28 46 a. mean: 43.5, mode: 46 b.

Dvinal [7]

Answer:

$\boxed{ \bold{ { \boxed{ \sf{mean \: = \: 42 \: , \: mode = 46}}}}}$

Option B is the correct option.

Step-by-step explanation:

Given data:

59 , 16 , 57 , 46 , 58 , 21 , 36 , 41 , 23 , 64 , 20 , 66 , 40 , 51 , 28 , 46

Σx ( sum of the items ) = 672

N ( total number of items ) = 16

Finding the mean

$\boxed{ \sf{mean = \frac{sum \: of \: the \: items}{total \: number \: of \: items}}}$

$\longrightarrow{ \sf{ \frac{672}{16} }}$

$\longrightarrow{ \sf{42}}$

Mean = 42

Finding the mode

In the given data , 46 has the highest frequency.

So, mode = 46

Hope I helped!

Best regards! :D
