Answer:

1) Find the number of sides if the measure of an interior angle is 177o in a regular polygon. Remember that the sum of the angles is (n-2)*180. 2) Find the measure of each interior angle if a regular polygon has 15 sides. Remember that the sum of the angles is (n-2)*180.

Answer:

<u>Let the number of sides be x.</u>

One interior angle is 177°

One exterior angle is 180-177   (linear pair)

                                   = 3°

Exterior angle × Number of sides = 360

3*x = 360

x = 360/3

x = 120

Therefore, the polygon has 120 sides.

Answer:

Step-by-step explanation:

From Bayes' theorem is stated mathematically as the following equation:[2]

{\displaystyle P(A\mid B)={\frac {P(B\mid A)\,P(A)}{P(B)}},}

where A and B are events and P(B) ≠ 0.

P(A) and P(B) are the probabilities of observing A and B without regard to each other.

P(A | B), a conditional probability, is the probability of observing event A given that B is true.

P(B | A) is the probability of observing event B given that A is true.

At this point, go through the attached file before you continue with part B.

Part B)

P(silver) = P(silver from SS)+P(silver from GS)

note P(SS)=P(GG)=P(GS) = 1/3

P(silver from SS) = 1

P(silver from GS) = 1/2

hence

P(Silver from SS) = 1/3

P(Silver from GS) = 1/3 *1/2

P(Silver) = 1/3*1+1/3*1/2

required probability = P(Silver from SS)/P(Silver) = 2/3

Micheal is building an iron man from junk in his dad's yard: he starts with a prototype of 1.8m high:he wants to make it 120m hi
finlep [7]
Ok, so the first thing you need is how much taller the second model is than the first model the way we do that is we take the second model height and divide that by the first model height 120/1.8=66.667 or 66 2/3 Second now we need to multiply the length of the middle finger by 66.667
6*66.667=400 cm now we just need to convert 400 cm to meters and since there are 100 cm in a meter we can do this 400/100=4 me so the answer is the little finger needs to be 4 meters long.
