To find percent error, you subtract the actual number from your estimate, take the absolute value, and divide by the actual number.

l 96 - 118 l
l -22 l
l 22 l
l 22 l / 118
0.19% (this was rounded)

Hope this helps!

Helga [31]

Answer:

The equation representing the value of n is, $n=\frac{S}{180^{\text{o}}}+2$ .

Step-by-step explanation:

The formula to compute the sum of the degrees, S, of the interior angles of a polygon is:

$S=(n-2)\times 180^{\text{o}}$

Compute the equation of n as follows:

$S=(n-2)\times 180^{\text{o}}$

$\frac{S}{180^{\text{o}}}=(n-2)$

$n=\frac{S}{180^{\text{o}}}+2$

Thus, the equation representing the value of n is, $n=\frac{S}{180^{\text{o}}}+2$ .

Hi there! Can someone help me with this, i need a proper answer, i don't need LINKS or FILES for the explanations.

Answer:

Using below system of inequalities

y > 2x - 3
y < x + 1

Following the rules

1. Finding x- and y - intercepts
2. Connecting with dotted line for each as no equal symbol present in any inequality
3. Shade respective regions
4. Solution is the intersection of the shades regions
5. Select any three points in the solution region

Line 1

y > 2x - 3
x- intercept: y = 0 ⇒ 0 = 2x - 3 ⇒ 2x = 3 ⇒ x = 1.5
y - intercept: x = 0 ⇒ y = -3
Shaded region is above the line (or to the left)

Line 2

y < x + 1
x- intercept: y = 0 ⇒ 0 = x + 1 ⇒ x = -1
y - intercept: x = 0 ⇒ y = 1
Shaded region is below the line (or to the right)

Selected points are:

(-1, -1), (1, 1), (2, 2)
