An unfair coin with Pr[H] = 0.75 is flipped. If the flip results in a head, a student is selected at random from a class of si

Agata [3.3K]

Answer:

72.73% probability of selecting a girl, given the flip resulted inheads

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Coin resulted in heads

Student is selected at random from a class of six boys and sixteen girls.

Desired outcomes:

16 girls, so $D = 16$

Total outcomes:

16+6 = 22, that is, 22 students, so $T = 22$

Probability:

$P = \frac{16}{22} = 0.7273$

72.73% probability of selecting a girl, given the flip resulted inheads

What would the answer to this question be? A. 40° B. 60° C. 80° D. 100°

Alex777 [14]

Answer:

D. 100°

Step-by-step explanation:

A straight line is 180°. Add 50° and 30° (which is 80°) and subtract the total from 180°.

50 + 30 = 80

180 - 80 = 100

Helppppppppppppp plzzzzzzzzzzzzzzzzzzzzzz

Answer:

These parallel lines cross 1 line. Because they are parallel they will form the same angles on that line. Therefore, x+50 = 3x-100 since those angles are corresponding angles made by a pair of parallels.

To find x we need to find what value of x gives the same answer for 3x-100 and x+50 since those 2 angles are equal.

x+50 = 3x-100 - now all we need to do is solve for x:

x+50 = 3x-100

50=2x-100

150=2x

75=x

x=75
