- The electric power P of a direct current circuit is jointly proportional to the voltage V and the electric current I.Find a mathematical model for the verbal statement.arrow_forwardEquations: a) What is the solution to the following equation (give your answer to 4 decimal places): 7x+1 = 11. b) What are the solutions to the following equation: 4(2x)2 -17(2x) + 4 = 0arrow_forwardConsider an equation to explain the Academic Performance of students (AP) presented in equation 1.3. In the equation, S, T and A refer to the number of hours the student studies (S), the number of textbook the student buys (T) and class attendance (A). AP = 4.32 + 0.280S + 0.0174A + 0.00024T + µ (1.1) (0.32) (0.035) (0.0041) (0.00054) N = 209, R2 = 0.283 Using equation 1.1, test the hypothesis that T, the number of textbooks the student buys has no effect on Academic Performance (AP), against the alternative that it has a positive effect at the 5% significance level. At the 95 percent confidence interval, test the hypothesis that class attendance by the student has no effect on the student's academic performance.arrow_forward
