In one city, there are a total of 1704

5 year old children of whom 598

live with one parent only. Among a sample of 606

of the 5 year old children from this city, 225

live with one parent only. Find the population proportion of 5 year olds who live with only one parent, rounded to two decimal places as needed.

The population proportion of 5 year old's who live with only one parent, for city & sample is 0.350 & 0.371 respectively.

Step-by-step explanation:

We have , In one city, there are a total of 1704 ,  5 year old children of whom 598  live with one parent only. Among a sample of 606  of the 5 year old children from this city, 225  live with one parent only.

Population proportion is the ratio of Number of 5 year old child's with one parent only to Total Number of 5 year old children. i.e.

Population proportion for city:

⇒

⇒

Population proportion for sample:

⇒

⇒

∴ The population proportion of 5 year old's who live with only one parent, for city & sample is 0.350 & 0.371 respectively.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

i got 86 for this

hope this !
