What statement best describes the earth ocean

The last part is function but need help asap The following model is a simplified version of the multiple regression model used by Biddle and Hamermesh (1990) to study the tradeoff between time spent sleeping and working and to look at other factors affecting sleep:sleep = 0 + 1totwrk + 2educ + 3age + u,where sleep and totwrk (total work) are measured in minutes per week and educ and age are measured in years. (See also Computer Exercise.)(i) If adults trade off sleep for work, what is the sign of 1?(ii) What signs do you think 2 and 3 will have?(iii) Using the data in SLEEP75.RAW, the estimated equation is= 3,638.25 - .148 totwrk - 11.13 educ + 2.20 age n = 706, R2 = .113.If someone works five more hours per week, by how many minutes is sleep predicted to fall? Is this a large tradeoff?(iv) Discuss the sign and magnitude of the estimated coefficient on educ.(v) Would you say totwrk, educ, and age explain much of the variation in sleep? What other factors might affect the time spent sleeping? Are these likely to be correlated with totwrk?Use the data in SLEEP75.RAW from Biddle and Hamermesh (1990) to study whether there is a tradeoff between the time spent sleeping per week and the time spent in paid work. We could use either variable as the dependent variable. For concreteness, estimate the modelsleep =0+ 1totwrk+u, where sleep is minutes spent sleeping at night per week and totwrk is total minutes worked during the week.(i) Report your results in equation form along with the number of observations and R2. What does the intercept in this equation mean?(ii) If totwrk increases by 2 hours, by how much is sleep estimated to fall? Do you find this to be a large effect?

Marc eats an egg sandwich for breakfast and a big burger for lunch every day. The egg sandwich has 250 calories. If Marc has 5,250 calories for breakfast and lunch for a week in total, how many calories are in one big burger. The two lines graphed below are not parallel. How many solutions are there tothe system of equations? A ticket to see your favorite baseball team costs $30.08. That price decreases by $0.42 for every game lost during the regular season. What equation could you use to find the cost C of a ticket after L losses? Represent the total change in the cost of a ticket after the team loses 27 games. What is the price of a ticket after the team loses 27 games? Find the slope of the line that passes through the points (2,6 ) and ( 4 , 12) Bird Corp.'s trademark was licensed to Brian Co. for royalties of 15% of the sales of the trademarked items.
