Solve the equation. Give a general formula for all the solutions. List six solutions.\\ cos \theta = -\frac{\sqrt{3}}{2}\\ Write the general formula for all the solutions to cos \theta = -\frac{\sqrt{3}}{2} based on the smaller angle.\\ \theta = \boxed{}\\(Simplify your answer. Use angle measures greater than or equal to 0 and less than 2\pi. Type an exact answer, using \pi as needed. Use integers or fractions for any numbers in the expression. Type an expression using k as the variable.)\\Write the general formula for all the solutions to cos \theta = -\frac{\sqrt{3}}{2} based on the larger angle.\\ \theta = \boxed{}\\(Simplify your answer.

#04-2020-1000-911 CSCI 150 5. (5pt) Datapath design. You are charged with the duty to design a datapath with eight 8-bit GPRs. The datapath has the following operations, upon receiving Instruction $M_{1:0}$: - $M_{1:0} = 00$: Load input $X_{7:0}$ into register with address $A_{2:0}$ - $M_{1:0} = 01$: Output register with address $A_{2:0}$ to output $F_{7:0}$ - $M_{1:0} = 10$: Add register $A_{2:0}$ with input $X_{7:0}$, store the results back into register $A_{2:0}$ - $M_{1:0} = 11$: Swap the values of register $A_{2:0}$ and $X_{2:0}$ Draw the circuit diagram of this datapath, with input $M_{1:0}$, $A_{2:0}$, $X_{7:0}$ output $F_{7:0}$. You may use any combinational func- tional blocks we've covered in class. You do not have to care about output $F_{7:0}$ in $M_{1:0} = 00, 10, 11$. Include the dia- gram in your submission PDF.

1. Below is a training set with 20 points. The lighter colored points have correct label -1, and the black points (the top-most point and the right-most point) have correct label +1. Give $\theta$, $j$, and $b$ for a decision stump that minimizes empirical risk (using equal weights $p = (1/20, 1/20,..., 1/20)$). State what the empirical risk of that decision stump is.

4. A number of studies in the labor economics literature have analyzed the relationship between income and education. We would expect, on average, higher levels of education to be associated with higher incomes. The simple regression model income = \beta_0 + \beta_1 education + \epsilon, however, neglects the existence of gender discrimination. A) (15 POINTS) What is the impact of omitting 'gender' from the equation on the estimated coefficient of 'education'? (Hint: Assume that women are more educated than men). B) (10 POINTS) It is often observed that income tends to rise less rapidly in the later earning years than in the early ones and then starts decreasing around the retirement age. How can you model such a theoretical relationship (i.e., write down the regression equation)? What would the expected signs of the estimated coefficients be?
