The frequency table represents data gathered about how much time some farmers spend tending to their land each week. complete the conditional relative frequency table by row by identifying the values for each letter.

a=0.6

b=0.4

c=0.2

d=0.8

Step-by-step explanation:

a = 0.6; b = 0.4; c = 0.2; d = 0.8

Step-by-step explanation:

The value of a represents the 180 out of 300 in the first row.  180/300 = 0.6.

The value of b represents the 120 out of 300 in the first row.  120/300 = 0.4.

The value of c represents the 40 out of 200 in the second row.  40/200 = 0.2.

The value of d represents the 160 out of 200 in the second row.  160/200 = 0.8.

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

it is b)
