Davis used a drawing and a scale factor of 4 to design
his triangular yard. The area of the yard is 400 ft. He
wants to find the area of the scale drawing.
Davis knows that the original area times the square of
the scale factor will equal the enlarged area. What is
the area of the scale drawing?
(Scale drawing)(Scale factor)? = Enlarged Area
Area = x
(x)(4)2 = 400
16x = 400
Area = 400 ft?

Find the zeros of each function. f(x) = x^2 + 5x - 6

Acell phone company offers two plans to its subscribers. at the time new subscribers sign up, they are asked to provide some demographic information. the mean yearly income for a sample of 40 subscribers to plan a is $45,000 with a standard deviation of $9,200. for a sample of 25 subscribers to plan b, the mean income is $64,300 with a standard deviation of $7,100. at the 0.025 significance level, is it reasonable to conclude the mean income of those selecting plan b is larger? assume unequal population standard deviations. hint: for the calculations, assume the plan a as the first sample. what is the decision rule? (negative amount should be indicated by a minus sign. round your answer to 3 decimal places.) compute the value of the test statistic. (negative amount should be indicated by a minus sign. round your answer to 2 decimal places.) what is your decision regarding h0 ? reject h0 fail to reject h0 compute the p-value. less than 0.01 between 0.01 and 0.025 between 0.025 and 0.05 between 0.05 and 0.10 greater than 0.10
