The percent of error can be found by dividing the difference in weights by the predicted weight.
290 - 258 = 32 pounds
32/258 = 0.124
0.124 = 12.4% approximately was the percent of error
Answer:
4−2x<−3
Step-by-step explanation:
check:
now --- 4°
after 1 hr --- 2°
after 2 hrs--- 0°
after 3 hrs--- -2°
after 4 hrs--- -4°
so between 3 and 4 hrs it will reach -3°
4-2x < -3
-2x < -7
x > 3 1/2
Answer: All heights could be the same based on probability
Step-by-step explanation:
Hello,
Let's assume t the time for counting one step
V the girl velocity in t
v the escalator velocity in t
d the length to go upstairs
going up: V*60+v*60=d
walking down: V*90-v*90=d
so
V+v=d/60
V-v=d/90
2V=d*5/180
V=d*5/360
V=d/72
V*72=d The girl must count to 72 steps.(here v=0)
