The table below summarizes the number of children per household for a sample of 37 families.

What is the mean number of children per household for these families? Round your answer to the nearest tenth.

2.9

Step-by-step explanation:

the mean number is (total number of children / number of households)

to find the total number of children, multiply the number of households by the number of children per household in each row and add them together

total number of children = (9*4)+(14*2)+(14*3) = 106

number of households = 9+14+14 = 37

mean = 106/37 = 2.86486

which rounds to 2.9

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
