Answer:
0.4494
Step-by-step explanation:
Given :
marks number of students
20-29 8
30-39 12
40-49 20
50-59 7
60-69 3
The range Coefficient is obtained thus :
Range Coefficient = (Xm - Xl) / (Xm + Xl)
Where ;
Xm = Mid value of highest class = (60+69)/2 = 64.5
Xl = Mid value of lowest class = (20+29)/2 = 24.5
Range Coefficient = (64.5 - 24.5) / (64.5 + 24.5)
Range Coefficient = 40 / 89 = 0.4494
Answer:
The answer is 3rd point
Step-by-step explanation:
By looking at the table :
10-10.99,
$15.95 (1 dot)
20-29.99,
$21.52, $25.55, $27.78, $29.90 (4 dots)
30-39.99,
$33.98, $36.77 (2 dots)
40-49.99,
$43.44 (1 dot)
50-59.99,
$51.25 (1 dot)
60-69.99,
$60.54, $64.56, $67.89 (3 dots)
Then you can determine number of dots in each range.
Answer:idk
Step-by-step explanation:
A) From the given graph, we can see that the point where graph functions p(x) and f(x) intersect is seen to be;
x = 1, y = 5.0125
B) The possible solutions of the given equation will be; x = 3.11 or -3.11
C) The solution to p(x) = g(x) is; x = 0 and y = 0
<h3>How to find the solution to simultaneous equations graphically?</h3>
When we are trying to solve two simultaneous equations, there are three methods we can use namely;
1) Elimination Method
2) Substitution Method
3) Graphical Method
Now, we see that we are to use the graphical method from the given graph.
Now, the solution to the given pair of equation will be the coordinates of the points where both graphs intersect.
A) From the given graph, we can see that the point where graph functions p(x) and f(x) intersect is seen to be;
x = 1, y = 5.0125
B) The possible solutions of the given equation will be the point where f(x) = 0 which is where the line crosses the x-axis and so we have;
x = 3.11 or -3.11
C) The solution to p(x) = g(x) is the coordinate;
x = 0 and y = 0
