Jamie and sara went shopping at the mall. jamie spent $25 more than three times what sara spent. jamie spent $154.

which equation will us find how much sara spent?

x/3 + $25 = $154
x/3 - $25 = $154
3x + $25 = $154
3x - $25 = $154

Suppose a triangle has two sides of length 32 and 35, and that the angle between these two sides is 120°. which equation should you solve to find the length of the third side of the triangle?

(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.)
