The probability density function of the length of a metal rod is f(x) = 2.0 for 2.3 < x < 2.8 meters. if the specifications for this process are from 2.25 to 2.75 meters, what proportion of the bars fail to meet the specifications? assume that the probability density function is f(x) = 2.0 for an interval of length 0.5 meters. over what value should the density be centered to achieve the greatest proportion of bars within specifications?

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

17

step-by-step explanation:

51/3=17

thus 17 is your answer.
