1 answer:
Effectus [21]4 years ago
7 0

Answer:

it's 70°

Step-by-step explanation:

well first by vertical angles we know that

\angle BAC = \angle DAE\\\\\angle DAE = 4x+6 ( I don't know how to put the symbol xd)

and given we know that

\angle EAF = \angle EAD = 4x+6

solving for x

we know that

\angle CAD = 180\\\\\angle CAB + \angle ABD = 180\\\\4x+6+6x+14=180\\\\10x+20=180\\\\10x=160\\\\x=16

and now for \angle EAF

\angle EAF = 4x+6\\\\\angle EAF = 4(16)+6\\\\\angle EAF = 64+6\\\\\angle EAF = 70

New probabilities that have been found using Bayes' theo- rem are called a. prior probabilities. b. posterior probabilities. c.
Sphinxa [80]

Answer:

b). posterior probabilities.

Step-by-step explanation:

Posterior Probabilities are described as the updated probabilities which are estimated employing the theorem proposed by Baye. According to his theorem, an association is developed between probability and the newly received information. <u>When the previously existing probabilities are amalgamated with this updated information, it gives the existing probabilities' value a correction, update, or revision namely 'posterior probabilities</u>.' Thus, it is the probability that asserts the truth of a hypothesis and hence, <u>option b</u> is the correct answer.

Semmy [17]

Answer:

Step-by-step explanation:

-5f=-3(8-f)

Opening bracket

-5f = - 24 + 3f

Collecting like terms

-5f - 3f = -24

-8f = -24

Dividing by -8

f = -24/-8

f = 3
