A committee of five people is to be formed from six lawyers and seven teachers. Find the probability that none are lawyers.
thirty animals are to be used in a medical experiment on diet deficiency: 3 male and 7 female rhesus monkeys, 6 male and 8 female dogs. If one animal is selected at random, what is the probability of getting a chimpanzee or a dog?
There is a woman that has a 40% chance of being in Casper recently, a 30% chance of being in Denver and a 27% chance that she has been to both. Find the probablility that she has been to Casper if she has been to Denver.
There is a woman that has a 40% chance of being in Casper recently, a 30% chance of being in Denver and a 27% chance that she has been to both. Find the probablility that she has been to Casper or Denver recently.
If you are given odds of 3 to 4 in favor of winning a bet, what is the probability of winning the bet?
F=4000sin(20)= 1368.1 FF= 0.3*4000cos(20)= 1127.6 FR= 4000sin(20) + 0.3*4000cos(20)= 2495.7 So 2495.7 N required to move it up the slope 1127.6 N is required to prevent the load from sliding back
W=mg= 4000 or do i multiply this by 9.81
A 4000N block is moved up a slope that is 20 degrees to the horizontal. If the coefficient of friction is 0.3, find the force parallel to the slope to: a) move the load up the slope b) prevent the load from sliding back
The graph below shows the expected monthly temperature of a certain city from April to August; the readings that correspond to the vertical lines are taken on the first day of each month. (For example, the expected temperature on April 1 is 70 degrees.)
To test H0: = 80 versus H1: < 80. a simple random sample of size n = 22 is obtained from a population that is known to be normally distributed. a) If ¯x = 76.9 and s = 8.5, compute the test statistic.
