The given equation is a Quadratic equation, so it's graph must be a parabola, and the Coefficient of x² is positive that means the parabola must have an opening upward.
And 2 is added to the ideal equation, so the parabola must have shift 2 units up from x - axis.
From the above information, we can easily conclude that the Correct representation is done in graph 4
The equation in slope-intercept form is:
Further explanation:
The standard slope-intercept form is:
Given equation is:
In order to bring the equation in slope-intercept form we have to isolate y on left hand side of equation
So,
<u>Adding 2x on both sides</u>
<u>Dividing both sides by 3</u>
<u>Simplifying</u>
The equation in slope-intercept form is:

Answer:
Mean = 21.3
Standard Deviation = 2.48
Step-by-step explanation:
We are given the following in the question:
p = 71% = 0.71
Sample size, n = 30
We have to find the mean and the standard deviation of those that wear glasses.
Thus, the mean of those who wear glasses is 21.3
Thus, the standard deviation of those who wear glasses is 2.48
