Your initial post is due by Thursday, July 31st, 11:59pm ET. For full credit, your post must include the following items: The notation $y'(t) = \frac{dy}{dt} = \frac{d}{dt}y$ was devised to suggest that the derivative of a function $y$ is the result of operating on the function $y$ with the differentiation operator $\frac{d}{dt}$. Indeed, second derivatives are formed by iterating the operation: $y''(t) = \frac{d^2y}{dt^2} = \frac{d}{dt}\frac{d}{dt}y$. Commonly, the symbol D is used instead of $\frac{d}{dt}$, and the second-order differential equation $y'' + 4y' + 3 = 0$ is represented by $D^2y + 4Dy + 3y = (D^2 + 4D + 3)[y] = 0$. Question: is $(D + 8t)D$ the same as $D(D + 8t)$? Please show your work to support your conclusion. You may write your solutions on a scrap paper and then take a picture of it and then upload it. Or you may insert Math equation directly when you reply to the thread.

The admissions officer at a small college compares the scores on the Scholastic Aptitude Test (SAT) for the school's in-state and out-of-state applicants. A random sample of 9 in-state applicants results in a SAT scoring mean of 1165 with a standard deviation of 44 . A random sample of 13 out-of-state applicants results in a SAT scoring mean of 1220 with a standard deviation of 55 . Using this data, find the 98% confidence interval for the true mean difference between the scoring mean for in-state applicants and out-of-state applicants. Assume that the population variances are not equal and that the two populations are normally distributed. Step 3 of 3 : Construct the 98% confidence interval. Round your answers to the nearest integer.

1. (30 pts) A ferromagnetic core with a relative permeability of 1500 is shown in Figure. The dimensions are as shown in the figure, and the depth of the core is 5 cm. The air gaps on the left and right sides of the core are 0.050 and 0.070 cm, respectively. If there are 2000 turns in the coil wrapped around the center leg of the core and if the current in the coil is 1.02 A, what is the flux in center leg of the core? ($\mu_0 = 4 \pi 10^{-7}$)
