Let Are the vectors $x^{(1)}(t)$, $x^{(2)}(t)$ and $x^{(3)}(t)$ linearly independent? choose If the vectors are independent, enter zero in every answer blank since those are only the values that make the equation below true. If they are dependent, find numbers, not all zero, that make the equation below true. You should be able to explain and justify your answer. $x^{(1)}(t) = \begin{bmatrix} 3e^t \\ e^t \end{bmatrix}$, $x^{(2)}(t) = \begin{bmatrix} 0 \\ 4e^t \end{bmatrix}$, $x^{(3)}(t) = \begin{bmatrix} 3e^t \\ 21e^t \end{bmatrix}$ $\begin{bmatrix} 0 \\ 0 \end{bmatrix} = \boxed{\phantom{X}} \begin{bmatrix} 3e^t \\ e^t \end{bmatrix} + \boxed{\phantom{X}} \begin{bmatrix} 0 \\ 4e^t \end{bmatrix} + \boxed{\phantom{X}} \begin{bmatrix} 3e^t \\ 21e^t \end{bmatrix}$

A study indicates that CB radio use slows down activity in the brain. As part of a randomized crossover study, 60 participants were fitted with a CB radio device on each ear and then underwent two positron emission topography, or PET, scans to measure brain glucose metabolism. During one scan, the CB radios were both turned off. During the other scan, an automated 50 -minute muted signal was sent to the radio on the right ear. The order of when the signal was received (for the first or second scan) was randomized. Comparison of the PET scans showed a significant decrease in activity in the part of the brain closest to the antenna during the transmisslon of the automated signal. Complete parts a and b . a. Identify the response variable and the explanatory variable. What is the response variable? A. Whether a signal was sent to the radio or not B. Brain activity during the scan C. The 60 participants D. The length of the signal

A research company polled a random sample of 799 U.S. teens about Internet use. 49% of those teens reported going online several times a daylong dash—a fact of great interest to advertisers. The 95% confidence interval for this number is from 45.6% to 52.5%. Complete parts a and b below. Question content area bottom Part 1 a) Interpret the interval in this context. A. One is 95% confident that, if one were to ask all teens whether they go online several times a day, between 45.6% and 52.5% of them would say they do. B. There is a 95% chance that, if one were to ask all teens whether they go online several times a day, 49% of them would say they do. C. There is a 95% chance that, if one were to ask all teens whether they go online several times a day, between 45.6% and 52.5% of them would say they do. D. One is 95% confident that, of the 799 teens polled, between 45.6% and 52.5% of them said that they go online several times a day. Part 2 b) Explain the meaning of "95% confident" in this context. A. If one were to collect many random samples of 799 teens, about 95% of the confidence intervals one constructs would contain the true proportion of all teens who admit to going online several times a day. B. There is about a 95% chance that the true proportion of all teens who admit to going online several times a day is contained within the bounds of the confidence interval. C. If one were to collect many random samples of teens, about 95% of the confidence intervals one constructs would contain the true sample proportion of teens who admit to going online several times a day. D. If one were to collect many random samples of teens, about 95% of the confidence intervals one constructs would contain the true proportion of all teens who admit to going online several times a day.

(a) Your answer is correct. Prepare a Computation and Allocation Schedule for the difference between book value and the value implied by the purchase price in the consolidated statements workpaper on the acquisition date. (Round present value factor calculations to 5 decimal places, eg. 1.25136 and final answers to 0 decimal places, eg. 5,125) (b) Your answer is partially correct. Prepare the workpaper entries necessary on December 31, 2013, to allocate and depreciate the difference between book value and the value implied by the purchase price.
