Can somebody please help me with this.!
densk [106]

Answer:

1260

Step-by-step explanation:

First you will need to find the amount of sides of the polygon:

(After looking it is 9)

Each angle of the side of a nonagon is 140 degrees.

Multiply by 9 since you can make 9 triangles:

140 x 9 = 1260

GUYS PLEASE HELP ME I WILL GIVE BRAINLIEST, 5 STARS, AND EVERYTHING! THANKS!
vekshin1

Answer:

3

Step-by-step explanation:

C(n) = 5n, 0 ≤ n ≤ 10       You would use this equation for finding the cost of 10 shirts. Since 10 is equal to 10.

C(n) = 5n, 0 ≤ n ≤ 10 ← You can ignore the 0 ≤n ≤10 part.

C(10) = 5(10)                 Input the value 10 as x.

C(10) = 50                    Simplified

Next,

C(n) = 4n + 5, n > 10      You would use this equation for finding the cost of 12shirts. Since 12 is greater than 10.

C(n) = 4n + 5, n > 10  ←  You can ignore the n>10 part.

C(12) = 4(12) + 5, n > 10  Input the value of 12 as x.

C(12) = 48 + 5                 Simplify

C(12) = 53    

Finally,

The question is asking you to find the difference between the cost of 12 shirts and the cost of 10 shirts. So the formula would be C(12) - C(10).

C(12) - C(10)

(53) - (50)                       Input the values of C(12) and C(10).

= 3                                  Simplify.

The answer is 3.

Suppose the number of residents within five miles of each of your stores is asymmetrically distributed with a mean of 25 thousan
ohaa [14]

Answer:

P(\bar X\:>27.8\:thousand)=3.07\%

Step-by-step explanation:

Since the number of residents within five miles of each of your stores is asymmetrically distributed, the distribution of the sample means will be approximately normal with a mean of 25 thousand.

The standard deviation of the sample means is:

\sigma_X=\frac{\sigma}{\sqrt{n} }

\implies \sigma_X=\frac{10.6}{\sqrt{50} }=1.4991

The z value is z=\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n}} }

We plug in the values to get:

z=\frac{27.8-25}{1.4991}=\frac{2.8}{1.4991}=1.87

The area to the right of 1.87 is 1-0.96926=0.03074.

The probability that the average number of residents within five miles of each store in a sample of 50 stores will be more than 27.8 thousand is 3.07%
