Well the median is the middle number, so I would say whenever the mean is lower than the median
Answer:
486kg
Step-by-step explanation:
density = mass / volume
2.7 = m / (100 x 60 x 30) **** Note the conversion to cm as the density is given in g/cm.
2.7 = m / 180000
m = 486000g
Now convert to mass in kg:
486000 g x 1 kg / 1000 g = 486kg
Answer:
51.1 ≈ r
Step-by-step explanation:
"A bicycle wheel travels 321 in for each revolution"- means that 321 is the circumference of the wheel that is a circle.
C = 2· π· r
What is the radius of the wheel ?
321 = 2· π· r, divide both sides of the equation by 2 π
(321/2·π) = r , use calculator, solve and round the answer
51.1 ≈ r
Time = 11/2 = 5 1/2
Road = 4 1/2 miles
Speed = 5 1/2 : 4 1/2 = 1 2/9 <------------answer
