Hugh transferred a balance of $3050 to a new credit card at the beginning of
the year. The card offered an introductory APR of 6.7% for the first 4 months
and a standard APR of 32.8% thereafter. If the card compounds interest
monthly, which of these expressions represents Hugh's balance at the end of
the year? (Assume that Hugh will make no payments or new purchases
during the year, and ignore any possible late payment fees.)

Ascientist studied a population of workers to determine whether verbal praise and/or tangible rewards affect employee productivity. in the study, some workers were offered verbal praise, some were offered tangible rewards (gift cards, presents, and some were offered neither. the productivity of each participant was measured throughout the study by recording the number of daily tasks completed by each employee. which inference might the scientists make based on the given information? a.) the number of daily tasks completed by each employee may influence the dependent variable, which is whether the employee receives verbal praise, tangible rewards, or neither. b.) verbal praise and/or tangible rewards may influence the independent variable, which is the number of daily tasks completed by each employee. c.) verbal praise and/or tangible rewards may influence the dependent variable, which is the number of daily tasks completed by each employee. d.) the dependent variables, which are verbal praise and tangible rewards, may influence the number of daily tasks completed by each employee.
