Answer:
Probability of tractor do not start = 7.67%
Explanation:
Given data:
Probability of not start at red = 6%
Probability of not start at white = 11%
Probability of not start at Blue = 8%
Percentage of tractors produced in red line = 48%
Percentage of tractors produced in white line = 31%
hence Percentage of tractors produced in white line = 1 - 0.48 - 0.31 = 0.21
Probability of tractor do not start 
Probability of tractor do not start = 0.0288 + 0.0231 + 0.0248 = 0.0767
Probability of tractor do not start = 7.67%
Answer:
Alcohol is a depressant, which means it slows the function of the central nervous system. Alcohol actually blocks some of the messages trying to get to the brain. This alters a person's perceptions, emotions, movement, vision, and hearing.
Explanation:
True
Answer:
sweat and vasodilation
Explanation:
Hyperthermia is when the body is too hot. (Not to be confused with hypothermia, when the body in too cold).
When we sweat, we are releasing moisture, like little bits of water, onto our skin. The water uses up heat energy from the body to evaporate. Because the body loses heat energy, it cools.
Vasodilation is when blood vessels widen. When this happens, the blood vessels are closer to the surface of the skin, allowing heat to escape through and exit the body.
Shivering and vasoconstriction would help to keep a person warm. Shivering makes the muscles on the body move, which increases heat. (Think of exercise, but on a small scale).
Vasoconstriction keeps blood vessels away from the surface of the skin.
