Here is the solution...
This is a proportional relationship.
A proportional relationship is nothing the two quantities vary directly with each other.
The proportional equation<em> y = k x</em>. where k is the constant proportionality.
This means that as <em>x</em> increases, <em>y </em>increases and as <em>x</em> decreases, <em>y</em> decreases.
Here we use the proportional relationship to find the equation.
The number of miles driven is proportional to the number of gallons of gas.
Therefore, the equation is Miles = k Gallons
That is <em>M = k G, </em>where k represents the number of miles driven per gallon of gas.
Higher the watts means the highest the intensity of that light bulb. also, the slope would be 1.1 which is positive and directly related to the watts. if watts goes up, then the function value will also go up.
The frequency of revision times is given by the product of the frequency
density value and the class width.
Correct response:
- The number of students are <u>72 students</u>
<h3>Methods of calculation using a histogram</h3>
The estimate of the number of students who revised for less than 45
minutes is given by the area, <em>A,</em> under the histogram to the left of the 45
minute mark as follows;
Frequency, f = Frequency density × Class width
Number of students = ∑f
Therefore;
A = 5 × 2 + 10 × 2.2 + 20 × 1.6 + 10 × 0.8 = 72
- The number of students that revised for less than 45 minutes = <u>72 </u>students
