Return on investment (ROI) is calculated using the formula (Net income / Cost of investment) x 100.
<h3>What is return on investment?</h3>
A return on investment or return on costs is a ratio between net income and investment.
The formula for return on investment (ROI) is given as;
ROI = (Net income / Cost of investment) x 100
A high return on investment means the investment's gains compare favorably to its cost. It is often used to measure the performance of an investment.
Thus, Return on investment (ROI) is calculated using the formula (Net income / Cost of investment) x 100.

Answer: 99.7% of babies learn to walk within 3 standard deviations from the mean in a normal distribution.
Explanation: In the normal distribution given here, that breaks down to about 68.2% between 7.5 and 10.5 months, 13.6% between 6 and 7.5 months, 13.6% between 10.5 and 12 months, 2.1% between 4.5 and 6 months and 2.1% between 12 and 13.5 months.
This is applying the percentages for the Standard Deviations shown on a Gaussian Curve.
The bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates.
<h3>What is a slope?</h3>
A slope is also referred to as gradient and it's typically used to describe both the ratio, direction and steepness of the function of a straight line.
<h3>How to calculate the slope of a line?</h3>
Mathematically, the slope of a line can be calculated by using this formula;
In conclusion, we can logically deduce that the bicycle function has the greater slope, which shows that the cost per hour is greater than that of the in-line skates.
