The following data was collected on a cheetah. it ran 1/2 mile in 2/3 min, 1/4 mile in 1/3 min, and 3/4 mile in 1 minute

1. explain how you know that this is a proportional relationship.

2 identify the constant of proportionality, and write an equation for the proportional relationship.

3. make a table and a graph of proportional relationship.

4. identify a point on a the graph that gives the constant of proportionality as the y-coordinate.

(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.)

Solve for x and select the correct answer

Find the unit rate. enter your answer as a mixed number. a fertilizer covers 2/3 square foot in 1/2 hour.
