a) mean: add all numbers and then divide them.. so:

3+9+10+5+8+5+9+11+10+3+10= 83

83 divided by 11 = 83/11 or 7 4/11

b) median: the middle number of the sequence but put in order first.. so:

smallest to largest: 3,3,5,5,8,9,9,10,10,10,11

so then middle number: 9

c) mode: most frequent (popular) figure/number.. so:

most frequent value: 10

d) range: difference between smallest number and largest number

so in this case: 11-3 = 8

e) positive direction

1. Find the sum of the measures of the interior angles of a convex 11-gon.

OleMash [197]

Answer:

The measure of the sum of interior angles of a 11-gon is $1620^{o}$ .

Each interior angle is approximately $147.273^{o}$ .

Step-by-step explanation:

A convex polygon has the measure of each interior angles to be less than $180^{o}$ .

But,

sum of interior angles of polygon = (n - 2) x $180^{o}$

where n is the number of sides of the polygon.

For a convex 11-gon, we have;

sum of angles of a 11-gon = (11 - 2) x $180^{o}$

= 9 x $180^{o}$

= $1620^{o}$

Sum of angles of a 11-gon = $1620^{o}$

To check: convex polygons' interior angles are less than $180^{o}$ .

so that,

each interior angle of 11-gon = $\frac{1620}{11}$

= $147.273^{o}$

Use a special right triangle to express sin 45 degrees as a fraction

Alekssandra [29.7K]

Answer:

Step-by-step explanation:

in a right angled triangle angles given are 45,90

Then third angle is also 45 °

as two angles are 45° each.

Then sides are also equal.

Let the equal sides be each =x

then hypotenuse=√(x²+x²)=√(2x²)=x√2

sin 45°=x/(x√2)=1/√2
