Answer:

3.6669

Step-by-step explanation:

Given is a frequency distribution and we are expected to find the mean of the distribution.

Let X be the no of total pets owned and f be the number of adults owning those pets.

Total

x 1 2 3 4 5 6 7

F 248 567 1402 728 419 456 203 4023

x*f 248 1134 4206 2912 2095 2736 1421 14752

Mean 3.666915237

Thus we find the total of all frequencies and then sum of product of x*f.

Mean = sum of f*x/sum of x

Here mean= 3.6669

The algebraic equation is 4(0.25)+2x=17

STEP 1: Simplify both sides of the equation

1+2x=17 or 2x+1

STEP 2: Subtract both sides

2x = 16

STEP 3: Divide both sides by 2

2x/2 = 16/2

x = 8
