Let the three numbers be x, y and z respectively, then
x + y + z = 62 . . . (1)
y = x - 4 . . . (2)
z = 4x . . . (3)
The above three expressions could be used to represent the numbers.
Solving the three equations, putting (2) and (3) into (1) gives
x + x - 4 + 4x = 62
6x - 4 = 62
6x = 62 + 4 = 66
x = 66/6 = 11
x = 11.
y = 11 - 4 = 7
z = 4(11) = 44
x = 11, y = 7, z = 44.
Es la segunda media es 1.65, mediana es 1.65, y modo es 1.61
Answer:
1.01 minutes
Step-by-step explanation:
The length of the roll is given to be 304 ft, and Bob's velocity is 5ft/s.
Velocity is defined as the rate of change of displacement over time t:
The function can be expressed to make t the subject to calculate time taken by Bob;
Hence, it takes Bob 1.01 minutes to walk the length of the roll.
Answer:
5/4, 1.3, 1 8/25
Step-by-step explanation:
5/4 is equal to 1 1/4, which is 1.25
1.3 is still 1.3
1 8/25 is equal to 1.32, which is sliglightly greater than 1.3
