Many track runners believe that they have a better chance of winning if they start in the inside lane that is closest to the field. for the data below, the lane closest to the field is lane 1, the next lane is lane 2, and so on until the outermost lane, lane 6. the table displays the starting positions for the winners of 240 competitions. calculate the chi-square test statistic x2 used to test the claim that the probability of winning is the same regardless of starting position.

starting position 1 2 3 4 5 6

number of wins 33 44 32 36 45 50

a.12.592

b.15.541

c.9.326

d.6.750

The highest point on earth is the peak of mount everest if you climb to the top you would be approximately 29,035 feet above sea level at remembering that amount is 5280 feet percentage of the height of the mountain would you have to climb to reach a point 2 miles above sea level

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
