A regular polygon is equilateral (it has equal sides) and equiangular (it has equal angles). To find the area of a regular polygon, you use an apothem — a segment that joins the polygon's center to the midpoint of any side and that is perpendicular to that side (segment HM in the following figure is an apothem).

Hope this helps tho I cant help with #2 sorry

Answer: The employee's expected earnings is 78.5.

Step-by-step explanation:

Since we have given that

$ Probability

0 0.07

25 0.12

50 0.17

75 0.14

100 0.28

125 0.18

150 0.04

We need to find the employee's expected earnings.

As we know the formula for "Expectation":

$E(x)=0\times 0.07+25\times 0.12+50\times 0.17+75\times 0.14+100\times 0.28+125\times 0.18+150\times 0.04\\\\E(x)=0+3+8.5+10.5+28+22.5+6\\\\E(x)=78.5$

Hence, the employee's expected earnings is 78.5.

Step-by-step explanation:

$m \angle DBE = \frac{1}{2} \{m (arc\: AC) + m (arc\: DE) \} \\ \\ = \frac{1}{2} (130 \degree + 40 \degree) \\ \\ = \frac{1}{2} \times 170 \degree \\ \\ \huge \purple{ \boxed{\therefore m \angle DBE = 85\degree}}$

Hence, option A 85° is the correct answer.

How many movies are 120 minutes or less in length?

borishaifa [10]

The movies of 120 min or less than 120 mins are 100

Further explanation:

A histogram is a visual representation of data.

In the given histogram we can see that

5 movies are 0 to 30 minutes, 10 movies are 31 to 60 minutes, 30 movies are 61 to 90 minutes, 55 movies are 91 to 120 minutes, and 15 movies are over 120 minutes.

In order to find the number of movies which are 120 minutes long or less than 120 minutes we will add up all the number of movies with 120 length and less than that

So,

$No.\ of\ movies\ 120\ min\ long\ or\ less\ than\ that = 5+10+30+55\\=100\ movies$

The movies of 120 min or less than 120 mins are 100
