The Earth is approximately 8.0 × 103 miles in diameter, from pole to pole. What number is the distance equivalent to?

The table respent two linear functions the equation respented by the first tables is given

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

(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.)
