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

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
