Question Solved1 Answer 7. A fruit grower claims that 20 % of his peach crop has been contaminated by medfly infestation. Find the probability that among 10 peaches inspected by this grower not more than 9 was contaminated by the medfly.

Sales performance. A chain that specializes in healthy and organic food would like to compare the sales performance of two of its primary stores in the state of Massachusetts. These stores are both in urban, residential areas with similar demographics. A comparison of the weekly sales randomly sampled over a period of nearly two years for these two stores yields the following information: Does it appear that one store sells more on average than the other store?

6 A can of cat food has volume V = 300 cm?. The radius of the can is r сm and the height is h cm. a Show that ar2h = 300. b Find an expression for the total surface area S of the can. c Substitute an expression for h (from part a) into your expression for s (from part b) and hence show that 600 S = 27er+ ds d Find dr e Find the minimum value of S and the values of r and h when this occurs and show that it is a minimum value.

Q2: An AM signal \( S_{A M}(t)=10 \cos \left(2 \pi 10^{6} t\right)+\sin \left(4 \pi 10^{3} t\right) \cos \left(2 \pi 10^{6} t\right) \). Determine: a) Carrier frequency b) Kind of AM e) Modulation index d) Total power e) Frequency spectra.

3. Draw both single-sided and double-sided frequency spectra of the following signals a) \( x_{1}(t)=2+\cos \left(100 \pi t+\frac{\pi}{6}\right)-\sin \left(150 \pi t-\frac{\pi}{3}\right) \) b) \( x_{2}(t)=3-4 \cos \left(2 \pi 10^{5} t-\frac{\pi}{6}\right)+3 \sin \left(5 \pi 10^{5} t-\frac{\pi}{3}\right) \)
