A manufacturer of ovens tests 10 ovens by cooking in each a 20 pound turkey. The turkeys are placed in 325 degrees Fahrenheit oven until a thermometer probe indicates that the turkey is “done” (when internal temperature reaches 165 degrees). The amount of time this takes is recorded for each oven. A 95% confidence interval for the time it takes is (246 ; 310) minutes. Which of the following would result in a smaller (narrower) confidence interval?

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

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
