Formulate the situation as a system of inequalities. (Let x represent the number of goats the farmer can raise and y represent the number of llamas.) A rancher raises goats and llamas on his 800-acre ranch. Each goat needs 4 acres of land and requires $70 of veterinary care per year, while each llama needs 10 acres of land and requires $56 of veterinary care per year. If the rancher can afford no more than $9,240 for veterinary care this year, how many of each animal can he raise?Find the vertices. (Order your answers from smallest to largest x, then from smallest to largest y.)

Let x represent the number of mountain climbers killed each year. The long-term variance of x is approximately σ2 = 136.2. Suppose that for the past 6 years, the variance has been s2 = 116.9. Use a 1% level of significance to test the claim that the recent variance for number of mountain-climber deaths is less than 136.2. Find a 90% confidence interval for the population variance. (a) What is the level of significance? State the null and alternate hypotheses....
