The height, in meters, of a machine piston can be modeled by the regression equation y = 4.4sin(0.4x - 1.7) +2.3, where x represents time, in seconds. To the nearest tenth of a meter, what is the height of the piston after 10 seconds? a) 1.6 m
b) 2.5 m
c) 3.3 m
d) 5.6 m

step-by-step explanation:

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
