QUESTION 9 TOVA is a computerized attention test used to help diagnose ADHD. An objective test could be a useful diagnostic tool since, according to the U.S. Centers for Disease Control, ADHD affects 7% of all school-age children. In trials the TÓVA test was found to have a sensitivity of 85% and a specificity of 709%. Suppose a group of researchers test 796 randomly chosen volunteers. Fill in the blanks in the chart to show the number of people that fall into each category. Round all values to the nearest whole number of people. Step 9: Reality Negative Positive Total Positive Test Negative Results Total

In a closed coiled helical spring the mean diameter of each coil is to be 10 times that of wire of the spring and the maximum shear stress is not to exceed 60 N/mm^2. Maximum permissible defelction under a load of 400 N is 10 cm. Taking the shear modulus as 9x104 N/mm^2, determine the number of coils, the diameter of coil and energy stoed in the coil.please solve this problem because tommorow is my exam

For the circuit below, use the node voltage method to create a system of equations for solving V1 and V2. 12? 2A 6? 4A 6? 3A Figure P3.6 Circuit for Problem 3.6. Enter the coefficient matrix of the system of equations, assuming: $\begin{bmatrix} x1 & y1 \\ x2 & y2 \end{bmatrix} \begin{bmatrix} V1 \\ V2 \end{bmatrix} = \begin{bmatrix} 72 \\ -12 \end{bmatrix}$ Using simultaneous solution of the equations you created, Find V1: Number Units Find V2: Number Units Find the current Ix: Number Units Given the circuit below with the following values: V1 = 16 V V2 = -12 V R1 = 2 ? R2 = 3 ? R3 = 2 ? R4 = 4 ? Determine an equation to define the node voltage V. Note: You need not simplify your mathematical formula. You can leave the KCL equation th from analyzing the node, as long as the only unknown variable is V. +V1 R1 R2 R3 R4 +V2 Calculate the node voltage V Number Units Calculate the current through R1 Number Units
