What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 7.5?

a rectangle is shown. the length of the rectangle is labeled as 8 cm, and the width is labeled as 6 cm.

perimeter = 58 cm, area = 209.25 cm2

perimeter = 58 cm, area = 2,700 cm2

perimeter = 210 cm, area = 2,700 cm2

perimeter = 210 cm, area = 209.25 cm2

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?
