Among coffee drinkers, men drink a mean of 2.8 cups per day with a standard deviation of 0.5 cups. Assume the number of drinking per day follows a normal distribution. What proportion drink 3 cups per day or more?

(y^2 + 10y + 25)/(y^2 - 9) * (y^2 + 3y)/(y + 5) (y+5)(y+5)/(y+3)(y-3) * y(y+3)/(y+5) (y+5)/(y-3) * y/1 y(y+5)/(y-3) or y^2+5y/y-3

A car is safely negotiating an unbanked circular turn at a speed of 17.2 m/s. The maximum static frictional force acts on the tires. Suddenly a wet patch in the road reduces the maximum static frictional force by a factor of three. If the car is to continue safely around the c...

A. m1a1=T-m1g and m2a2=T-m2g are your two equations, substitute and add and you get this --> T= (2xm1xm2)/(m1+m2) all multiplied by 9.8 (g). T= (2(3.0)(7.0))/(3+7) = 4.2(9.8) = 41.16 N B. Then just plug it in to one of your original equations. m1a1 = T-m1g (3.0)a = (41.16N)...
