Suppose the population of a town is 8,200 and is growing 3% each year. write an equation to model the population growth. predict the population after 3 years. y = 8,200 ∙ 3x; about 8,960 people y = 3 ∙ 8,200x; about 73,800 people y = 8,200 ∙ 3x; about 221,400 people y = 8,200 ∙ 1.03x; about 8,960 people

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)

(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.)

Hi i’m not sure how to do question 20 if u could explain how to do it that’d b great
