Answer:

8 = x

Step-by-step explanation:

all three sides are equal, so it is an equilateral triangle

if it is an equilateral triangle, each angle is 180/3 = 60 degrees

therefore

60 = 7x+4

subtract 4 from each side

60-4 = 7x+4-4

56 = 7x

divide by 7 on each side

56/7 = 7x/7

8 = x

Suppose you are given a fair coin and an unfair.com, which
horrorfan [7]

Answer:

9/25 or 36%

Step-by-step explanation:

The probability of selecting the fair coin is 1/2, and the probability of getting heads with the fair coin is 1/2.

P(fair) = 1/2, P(heads | fair) = 1/2

The probability of selecting the unfair coin is 1/2, and the probability of getting heads with the unfair coin is 2/3.

P(unfair) = 1/2, P(heads | unfair) = 2/3

P(fair and 2 heads) = 1/2 (1/2)²

P(fair and 2 heads) = 1/8

P(2 heads) = 1/2 (1/2)² + 1/2 (2/3)²

P(2 heads) = 1/8 + 2/9

P(2 heads) = 25/72

Therefore, the probability that you selected the fair coin, given that you flipped 2 heads, is:

P(fair | 2 heads) = (1/8) / (25/72)

P(fair | 2 heads) = (1/8) (72/25)

P(fair | 2 heads) = 9/25

Is any of this correct??
galina1969 [7]

2) you should put it in fraction terms, your answer is right, but it looks better as y/22

4) you don't need the dot, you can just write 2/3 x

7) same thing as 2, 2z/8

11) same thing as 2, c/4

They're all right :)
