Explanation Given that, the combined surface area of the circular and square solar cell is 40.0 cm 2 . From the figure, it is noted that, the total length of the circular and square solar cell kept adjacent to each other is 7 cm. Let r be the radius of the circle and s be the side of the square. Then, 2 r + s = 7 s = 7 − 2 r Substitute s in the equation for the combined surface area. π r 2 + s 2 = 40 π r 2 + ( 7 − 2 r ) 2 = 40 π r 2 + 49 − 28 r + 4 r 2 = 40 ( π + 4 ) r 2 − 28 r + 9 = 0 Further obtain the solution as follows

Please help me with the following statistic question

To evaluate the success of a 1-year experimental program designed to increase the mathematical achievement of underprivileged high school seniors, a random sample of participants in the program will be selected and their mathematics scores will be compared with the previous year’s statewide average of 525 for underprivileged seniors. The researchers want to determine whether the experimental program has increased the mean achievement level over the previous year’s statewide average. If alpha=.05, what sample size is needed to have a probability of Type II error of at most .025 if the actual mean is increased to 550? From previous results, sigma=80.
