You might think that increasing the resources available would elevate the number of plant speciesthat an area could support, but the evidence suggests otherwise. the data in the accompanyingtable are from the park grass experiment at rothamsted experimental station in the u. k., wheregrassland field plots have been fertilized annually for the past 150 years (collated by harpoleand tilman 2007). the number of plant species recorded in 10 plots is given in response to thenumber of different nutrients types added in the fertilizer treatment (nutrient types include nitrogen, phosphorus, potassium, and so number of nutrients added number of plant species1 0 362 0 363 0 324 1 345 2 336 3 307 1 208 3 239 4 2110 4 16what is the correlation between the number of nutrients added and the number of plant species?

Runners run around the school's football field. the cross country coach determines that the width of the field is seventy yards shorter than the length. part a write an expression that represents the perimeter of the football field. let x represent the length of the football field. include parentheses in your expression. next, write an equivalent expression that does not include parentheses. what property or properties did you use to simplify? explain. part b the cross country coach later determines that the length of the football field is 120 yards. all students must run five laps. using your answer from part a, determine the actual number of yards that each athlete must run in the tryouts. in order to make the team, students must complete the laps in 6 minutes. how quickly must they run each lap?
