The dance committee was given money to pay for a DJ and refreshments for the spring dance. After paying $125 to the DJ, the dance committee had $250 left to spend on refreshments. Which equation can be used to find a, the original amount of money the committee was given?

a−$125=$250

$125×a=$250

$250−$125 = a

$250÷a=$125

Akitchen floor is made up of tiles that are in the shape of the triangle shown there are 40 tiles on the kitchen floor what is the total area of the floor

(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.)
