PtichkaEL [24]

Yes; a triangle is formed:
<span>______________________________________________________</span>
m∡A = 17° ;
m∡B = 137° (given) ;
m∡C = 26° ;
   a = 6 ;
   b = 14 (given) ;
   c = 9 (given) .
______________________________________________________
Explanation:
______________________________________________________
Note:

The law of sines:

(sin A) / a = (sin B) / b = (sin C) / c ;
______________________________________________________
Given:
______________________________________________________
B = 137 ;
c = 9 ;
b =14 ;
______________________________________________________
(sin B) / b = (sin C) / c ;

(sin 137) / 14 = (sin C) / 9 ;

(0.681998360062) / 14 = 0.0487141685758571 = (sin C) / 9 ;
______________________________________________________

sin C = (0.0487141685758571) * (9) ;

sin C =  0.4384275171827139 ;

        Take the "arc sin" of each side of the equation; to isolate "C" on one side of the equation; and to solve for "C" ;

arc sin (C) = arc sin ( 0.4384275171827139) ;

           C = 26.003593520741 ; round to 26.

If all angles of a triangle add up to 180 degrees: then:

A + B + C = 180 ;

A + 137 + 26  = 180 ;

A + 163 = 180 ;

Subtract "163" from each side of the equation; to isolate "A" on one side of the equation; and to solve for "A" ;

A + 163 − 163 = 180 − 163 ;

      A = 17 ;

Now, to solve for "a" ;

(sin A) / a = (sin B)/ b ;

(sin 17) / a = 0.0487141685758571 ;

(0.0487141685758571) a = (sin 17) ;

Divide EACH SIDE of the equation by: "(0.0487141685758571)" ;
______________________________________________________
           to isolate "a" on one side of the equation; and to solve for "a" ;
______________________________________________________
[(0.0487141685758571)a ] / (0.0487141685758571) =

                   (sin 17) / (0.0487141685758571) ;
_________________________________________________________
                   a = (sin 17) / (0.0487141685758571) ;

                      = (0.292371704723) / (0.0487141685758571) ;

                   a = 6.0017796314787227112 ; round to "6" .

In a certain town in the united states, 40% of the population are democrats and 60% are republicans. The municipal government ha

Answer:

(a) 0.48, (b) 0.625, (c) 0.1923

Step-by-step explanation:

First define

Probability a person is a democrat: P(D) = 0.4

Probability a person is a republican: P(R) = 0.6

Probability a person support the measure given that the person is a democrat: P(SM | D) = 0.75

Probability a person support the measure given that the person is a republican: P(SM | R) = 0.3

Now for the Theorem of total probabilities we have

(a) P(SM) = P(SM | D)P(D)+P(SM | R)P(R) = (0.75)(0.4)+(0.3)(0.6) = 0.48

and for the Bayes' Formula we have

(b) P(D | SM) = P(SM | D)P(D)/[P(SM | D)P(D)+P(SM | R)P(R)] = (0.75)(0.4)/0.48 = 0.625

Now let SMc be the complement of support the measure, i.e.,

P(SMc | D) = 0.25 : Probability a person does not support the measure given that the person is a democrat

P(SMc | R) = 0.7: Probability a person does not support the measure given that the person is a republican,

and also for the Bayes' Formula we have

(c) P(D | SMc) = P(SMc | D)P(D)/[P(SMc | D)P(D)+P(SMc | R)P(R)] = (0.25)(0.4)/[(0.25)(0.4)+(0.7)(0.6)] = 0.1/(0.52)=0.1923
