1/6 is approximately 0.167
Represent the length and width by L and W. Then L = W + 4.
Using the perimeter formula: P = 2L + 2W = 68 ft = 2W) + 2(W+4).
Solve for W: 68 = 2W + 2W + 8, or 4W = 60. Thus, W = 15 and L = 19.
The dimensions of the rectangle are 15 by 19 feet.
45 black dogs because 2/3 of 60 is 45
The guarantee which should be given by the manufacturer in years is; 0.405years
<h3>Percentages and Averages</h3>
Since the average life of a scooter is 12 years with a standard deviation of 1.5 years.
Hence, the maximum life of any electric scooter is 13.5 years.
On this note, to offer a guarantee with the intention to replace only 3% of the scooters;
We must evaluate 3% of 13.5 years as follows;
- Guarantee offer = 3% of 13.5 years
