What is the area of the regular polygon?

Mathematics
1 answer:
BartSMP [9]3 years ago
6 0

Answer:

You could use the polygon area formula OR here's an easier solution

We draw the lines DC and DE

Angle ADC = 120°

Triangle ADC is a 30 60 90 triangle

In such a triangle Line AE = hypotenuse * sq root (3) /2

Line AE = 3 * 0.8660254038  = 2.5980762114

Line DE = 1.5

Area of Triangle ADE = .5 * 1.5 * 2.5980762114 =

1.9485571586   square meters and entire area of Triangle

ABC = 6 * 1.9485571586

which equals 11.6913429513  square meters

In 1980 and again in 2010, a Gallup poll asked a random sample of 1000 US citizens people "Are you in favor of the death penalty
Digiron [165]

Answer:

H0: p(1980) = p(2010) ; H1 : P(1980) > P(2010)

0.02

Step-by-step explanation:

Given that:

Sample size in both 1980 and 2010 = 1000 samples :

Proportion in favor :

P(1980) = 0.66

P(2010) = 0.64

To test the hypothesis :

Null hypothesis :

Proportion in favor are the same in both years

Null hypothesis = H0 = p(1980) = p(2010)

Alternative hypothesis :

Proportion in favor in 1980 is greater than that in 2010

Alternative hypothesis = H1 : P(1980) > P(2010)

The sample statistic :

P(1980) - p(2010)

0.66 - 0.64

= 0.02
