When testing for current in a cable with twelve color-coded wires, the author used a meter to test four wires at a time. how many different tests are required for every possible pairing of four wires?

The no of tests required shall be 495.

Explanation:

The possible pairing shall be the number of different ways in which 4 wires can be selected among a group of 12 different wires which is given by combinatorics as

Applying values we get

No of required ways are =

explanation:

allergens: overstimulate the nerve system

neurotics: attack nerve cells

mutagens: damage or otherwise alter dna sequence

generators: cause defects during growth and development  

carcinogens: cause unchecked cell growth

i hope you get the idea according to me these are the effects that happened.

swahili is an extremely rich and complex civilization, a set of ethnic groups articulated by a language and a series of cultural elements that fuse the african traditions, islam and indian culture. this growth was largely a result of the indian ocean trading network that brought in not just man-made riches, but also religious ideas, specifically islam, which had a significant impact on the local culture. furthermore, the development of the swahili language gave a common cultural unity to the people.
