An artifact originally had 16 grams of carbon-14 present. The decay model A = 16e-0.000121t describes the amount of carbon-14 present after t years. How many grams-14 will be present in 5715 years?

I've never been good at math he told he loves but he keeps cheating on me, so it ain't adding up sis

Based on the figures as marked, /\rqs = —

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
