Aprogram is seeded with 30 faults. during testing, 21 faults are detected, 15 of which are seeded faults and 6 of which are indigenous faults. what is the mill's estimate of the number of indigenous faults remaining undetected in the program?

Acompressor compresses a gas, a pump compresses a liquid. for a given pressure ratio, why does it take more work to compress a gas in a compressor than a liquid in a pump? a)- for a given pressure ratio the average specific volume for a gas is much higher than the average specific volume for a liquid. b)- there is no difference. the only difference is the amount of heat generated (not work) c)- for a given pressure ratio the average volurge for a gas is much higher than the average volume for a liquid. d)-there is no difference
