Asurvey asked a group of people the size of their household play the. aw something

The right answer is 2.36

first of all, we need to find "fx" where x is the Household size.

fx is the multiplication of "f" (that we called "frequency")and x, so we have:

Household size (x)                 Frequency (f)                    fx

           1                                           4                                 1 × 4 = 4

           2                                          12                              2 × 12 =24                   3                                           6                              3 × 6 = 18

           4                                            2                                4 × 2 = 8

           5                                            1                                5 × 1 = 5

now we need to far the total of frequency and fx or the "summation."

Total of fx (Σfx) = 4 + 24 + 18 + 8 + 5 = 59

Total frequency (Σf) = 3 + 4 + 6 + 7 + 5 = 25

and the final step to get the answer is to divide the Σfx and Σf

so,

Σfx/Σf=

59/25= 2.36

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
