Find the measure of each exterior angle of a regular pentagon

lyudmila [28]

Answer:

360

Step-by-step explanation:

The sum of the exterior angles of a regular polygon, irrespective of the number of sides is 360 degrees. If N is the number of sides, each exterior angle will be 360/N degrees. In the present case there 5 sides in a regular pentagon, hence each exterior = 360/5 or 72 degrees.

Answer:

The sample size to obtain the desired margin of error is 160.

Step-by-step explanation:

The Margin of Error is given as

$MOE=z_{crit}\times\dfrac{\sigma}{\sqrt{n}}$

Rearranging this equation in terms of n gives

$n=\left[z_{crit}\times \dfrac{\sigma}{M}\right]^2$

Now the Margin of Error is reduced by 2 so the new M_2 is given as M/2 so the value of n_2 is calculated as

$n_2=\left[z_{crit}\times \dfrac{\sigma}{M_2}\right]^2\\n_2=\left[z_{crit}\times \dfrac{\sigma}{M/2}\right]^2\\n_2=\left[z_{crit}\times \dfrac{2\sigma}{M}\right]^2\\n_2=2^2\left[z_{crit}\times \dfrac{\sigma}{M}\right]^2\\n_2=4\left[z_{crit}\times \dfrac{\sigma}{M}\right]^2\\n_2=4n$

As n is given as 40 so the new sample size is given as

$n_2=4n\\n_2=4*40\\n_2=160$

So the sample size to obtain the desired margin of error is 160.

Tasha was finding the area and perimeter of a square. The length of the square is 12 inches. What is the area and perimeter of t

krok68 [10]

Answer:

Area of square=144 square inche

Perimeter of square=48 inche

Step-by-step explanation:

length =12

Area of square=length x length

Area of square=12 x 12

Area of square=144

Area of square=144 square inche

Perimeter of square=4 x length

Perimeter of square=4 x 12

Perimeter of square=48

Perimeter of square=48 inche
