Yes she has enough money to buy both. 1.98+15.98=17.96 if you subtract that from 20 you get $2.04 back in change
This Question is actually for 44 points not 80 :(
M to millimetres is 3 steps. m > dm > cm > mm. since it is 3 steps down, the comma goes 3 places left. 4 > 0,4 > 0,04 > 0,004. so 4 m is equal to 0,004 mm
The answer is 310 because the total amount of miles is 650. So, you will subtract 340 from 650 giving you 310 miles to go.
In finding this value you average lower and upper bound
(0.6+0.82)/2 = 0.71
=0.71 estimated
margin of error = distance from estimate point lower/ upper bound
This interval will be twice margin error
(0.82-0.6)/2 = 0.11
How far is 0.82 from 0.71 ??
=0.11=11%
