What is the measure of an interior angle of a regular 12-gon?
gavmur [86]

Answer:

The measure of an interior angle of a regular 12-gon is 150°.

Hence, option 'C' is correct.                          

Step-by-step explanation:

We need to determine the measure of an interior angle of a regular 12-gon.

  • We know that the number of sides in a regular 12-gon = n = 12

Thus,

Using the formula to determine the measure of an interior angle of a regular 12-gon is given by

(n - 2) × 180° = n × interior angle

substitute n = 12

(12 - 2) × 180 = 12 × interior angle

10 × 180 = 12 × interior angle

Interior angle = (10 × 180) / 12

                      = 1800 / 12

                      = 150°

Therefore, the measure of an interior angle of a regular 12-gon is 150°.

Hence, option 'C' is correct.

5) 1,512 is 5 because 12,600× .12 leaves you 1512$ dollars off the original price.

6) 15.38 or 15.4% if you round to the nearest tenth. 32,800÷ 2132 leaves you the % additional of the raise can also be written as 32,800 = 2132x divide both sides and x being the percent is 15.4%.

7) the discount is 49.90$ another one like 5. multiply 499.00 x .10 = 49.9 also said as 49.90.

You are given that claims are reported according to a homogeneous Poisson process. Starting from time zero, the expected waiting
maxonik [38]

Answer:

1.732

Step-by-step explanation:

You are given that claims are reported according to a homogeneous Poisson process

LetX be the waiting time from 0 to second claim

X is Poisson with averageof 3 hours.

We know in a Poisson distribution the mean = variance

Hence average waiting time = mean = 3

This will also be equal to var(x)

Var(x) = mean of Poisson distribution= 3

Hence standard deviation = square root of variance

=\sqrt{3} \\=1.732
