Answer:
Step-by-step explanation:
From the given information:
suppose, the total number of people = n
Thus, the percentage of people believe in high school = 53% = 0.53
= n × m
The poll also let us understand that the number of people falls in margin error.
= ±n × M.O.E
where;
M.O.E = margin of error = ±5%
∴
the number of people falls in margin error. = ±n × 0.05 = 0.05 n
Thus, we can posit that the greatest percentage of people think for highschool was:
However, the least percentage of people think for highschool was:
The result of the integral based on the <em>incomplete</em> graph of is approximately 35.943. (Choice C)
<h3>Determination of an integral based on a graph and a given expression</h3>
Based on the information given on the figure, we have a set of points which resembles a <em>second order</em> polynomial, whose expression can be found by the fact that coefficients can be found by know three <em>distinct</em> points: , ,
Then, we form the following system of linear equations:
(1)
(2)
(3)
The solution of this system is: , , . Then, the expression of the <em>first</em> derivative is:
(4)
And the <em>second</em> derivative is:
(5)
Then, we have the following integral equation:
This choice that is closest to this result is C.

Answer: Answer is x = 5, y = -3
(5, -3)
Step-by-step explanation: The instruction is to use the substitution method, and from the first equation,
y = x - 8
This means we replace the value of y in the second equation with x - 8. Hence;
2x + 3y = 1 can now be re-written as
2x + 3(x - 8) = 1
2x + 3x - 24) = 1
5x - 24 = 1
Add 24 to both sides of the equation
5x -24 + 24 = 1 + 24
5x = 25
Divide both sides of the equation by 5
x = 5
Having calculated x as 5, we can now substitute for the value of x in the first equation
y = x - 8 now becomes
y = 5 -8
y = -3
