The manager of a small park randomly surveyed residents in the community and asked whether they visited the park in the past year. The table shows the results.

What is the 95% confidence interval for the difference between the percent of residents who are younger than 50 and who are 50 and older that visited the park in the past year?

pi x^2

step-by-step explanation:

pi times x squared

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours

step-by-step explanation:

the answer to 1/4x+5/3x-4=2-1/12x is x=3
