Two transmitters are prepared to send signals from a control tower to a receiver at a station a few miles away. To save on costs, the transmitters are not used equally. Transmitter A is used 30% of the time, and transmitter B is used 70% of the time. The receiver module is 90% effective at decoding the signal for transmitter A but only 60% effective for decoding the signal for transmitter B. The intelligence agency needs to be assured that the signals will be received and decoded at least 40% of the time so it doesn’t need to waste energy and money resending. Will this happen in this scenario?

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
