Two forces act on an object. the first force has a magnitude of 400 newtons and acts at an angle of 30 degrees as measured from the horizontal. second force has a magnitude of 280 newtons in accident angle of 135 degrees is measured from the horizontal. determine the vector v that represents the resultant force. a. v=(200-140rtsq2)i+(200rtsq3+140rtsq 2)j b. v=(200+140rtsq2)i+(200rtsq3+140rtsq 2)j c. v=(200rtsq3+140rtsq2)i+(200+140rtsq 2)j d. v=(200rtsq3-140rtsq2)i+(200+140rtsq 2)j

(co 3) the times that customers spend in a book store are normally distributed with a mean of 39.5 minutes and a standard deviation of 9.4 minutes. a random sample of 25 customers has a mean of 36.1 minutes or less. would this outcome be considered unusual, so that the store should reconsider its displays? no, the probability of this outcome at 0.035, would be considered usual, so there is no problem yes, the probability of this outcome at 0.035, would be considered unusual, so the display should be redone no the probability of this outcome at 0.359 would be considered usual, so there is no problem yes, the probability of this outcome at 0.965 would be considered unusual, so the display should be redone
