Tan (x + π/2) = [sin (x + π/2) / cos (x + π/2)] = [sin x cos π/2 + sin π/2 cos x] / [cos x cos π/2 - sin x sin π/2] = cos x / - sin x = -cot x

Answer:
HDTV Converters
a. The probability that the driver will have enough working converters = 80% (100 - 20%).
b. The driver should load 10 boxes (or specifically 9.5 boxes) to ensure a 95% probability of having enough working converters.
Step-by-step explanation:
a) Data and Calculations:
Probability of HDTV converters known to not work property = 20%
This implies that 80% (100 - 20%) will work properly.
Number of converters to install today in an apartment building = 8
Number of converters placed in the truck = 10
b) The probability that the driver will have enough working converters = the probability of having properly working converters, which is 80%. To ensure a 95 percent probability of having enough working converters, out of 10 converters, the number of boxes to load on the truck is 9.5 (10 * 95%) boxes. Since there are no half boxes, it means that 10 boxes must be loaded, approximated to the nearest convenient number.
Answer:Always put the image on top when you are trying to make it into a fraction, and put the pre-image on the bottom. Since the image is 18 we put the it on top and the 8 (pre-image) on the bottom 18. 18/8. Divide it. 18 ÷ 8.
