Here is a set of data. 2.4 1.6 3.2 0.3 1.5 a) calculate the mean b) each piece of data is increased by ten. calculate the new mean. c) each new piece of data is doubled. calculate the new mean.

C= 23.6

Step-by-step explanation:

I was also struggling with this but I worked it out

step-by-step explanation:

∠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.
