The data set represents the number of rings each person in a room is wearing.

0, 2, 4, 0, 2, 3, 2, 8, 6

what is the interquartile range of the data?

4

Step-by-step explanation:

First arrange the given data in ascending order :-

Number of terms = 9

Second quartile =Median=

Now, the first quartile =The median for the lower half of data

= Mean of 2nd term and 3rd term

The third quartile =The median for the upper half of data

= Mean of 7th term and 8th term

Now, Interquartile range =

Hence, the interquartile range of the data =4.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
