Matilda purchased a plot of land in a nearby rural area. The following function models the value of the land for the first 5 years, where t is the number of years since Matilda purchased the land. The value of the land increases by 7% every year. Find the value of r, and state what it represents. f(t) = a(1 + r)

Anew test for ra is being developed. the test is administered to 750 patients with ra and 750 without ra. for the sake of the question, assume the prevalence of ra in this population is 50%. of the 750 patients with ra, 575 have a positive result. of the 750 patients without ra, 150 have a positive result. what is the positive predictive value of the new test? a575/(575+150) b. 600/(600+ 150) c. 575/(575+125) d. 600/(600+ 125)

Combine like terms to create an equivalent expression. make sure to simplify coefficients and constants as well. -6/5-2/3v+4/15+1/3v
