Match each verbal description to its equivalent function rule as applied to the given function below. f(x) = 7x + 5 g(x) = 14x + 7 g(x) = 21x+17 g(x) = 7x – 18 g(x)-7x-16 g(x)=-7x-16 g(x)=7x+14 The function f reflected about the y-axis and translated 3 units left. The function f stretched vertically by a factor of 3 and translated up by 2 units. The function f translated 2 units down and 3 units right. The function f stretched vertically by a factor of 2 and translated down by 3 units.​

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
