68% fall within +/- 1 SD, so men above that 1 SD (165) are: (100-68)/2
32/2 = 16% above 165 and also 16% below 135
The area of the trampoline is mathematically given as
a = 3.14
<h3>What is the area?</h3>
Question Parameters:
You found one online that has a circumference of 6.28 yards
Generally, the equation for the Circumference is mathematically given as
C = 2*pi*r
Thererfore
6.28 = 2*3.14*r
r = (6.28)/(6.28)
r = 1
In conclusion, where radius is
a = 3.14*1^2
a = 3.14

Answer:
y = (1/4)x² - (5/4)x + 1
Step-by-step explanation:
The x-intercepts of the quadratic equation are simply it's roots.
Thus, we have;
(x + 1) = 0 and (x - 4) = 0
Now, formula for quadratic equation is;
y = ax² + bx + c
Where c is the y intercept.
At y-intercept: (0,1), we have;
At (-1,0), thus;
0 = a(1²) + b(1) + 1
a + b = -1 - - - (1)
At (4,0), thus;
0 = a(4²) + b(4) + 1
16a + 4b = -1
Divide both sides by 4 to get;
4a + b = -1/4 - - - (2)
From eq 1, b = -1 - a
Thus;
4a + (-1 - a) = -1/4
4a - 1 - a = -1/4
3a - 1 = -1/4
3a = 1 - 1/4
3a = 3/4
a = 1/4
b = -1 - 1/4
b = -5/4
Thus;
y = (1/4)x² - (5/4)x + 1
