Pi times 0.8 = 2.513274123 ( one trip )
2 times 2.513274123 = 5.02654826

The true probability of a baby being a girl is 0.475. What is the probability that at least one is a boy?
alex41 [277]

Answer:

The probability that at least one is a boy is 0.525

Step-by-step explanation:

P(Baby being a girl) = 0.475

Now, if A is any arbitrary event . Then:

as we know P(A)+ P(not A) = 1

⇒ P(A not happening)  = 1 - P(A event happening)

Also,  P( baby not being a girl) = P(baby being a boy)

So,  P(baby being a boy)  = 1 - P( baby being a  girl)

                                          = 1 - 0.475   = 0.525

Hence,  the probability that at least one is a boy is 0.525

Worth 20 points, first answer gets brainliest!

Answer:

x = -7

Step-by-step explanation:

Simplifying

5x + 130 = 8x + 151

Reorder the terms:

130 + 5x = 8x + 151

Reorder the terms:

130 + 5x = 151 + 8x

Solving

130 + 5x = 151 + 8x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-8x' to each side of the equation.

130 + 5x + -8x = 151 + 8x + -8x

Combine like terms: 5x + -8x = -3x

130 + -3x = 151 + 8x + -8x

Combine like terms: 8x + -8x = 0

130 + -3x = 151 + 0

130 + -3x = 151

Add '-130' to each side of the equation.

130 + -130 + -3x = 151 + -130

Combine like terms: 130 + -130 = 0

0 + -3x = 151 + -130

-3x = 151 + -130

Combine like terms: 151 + -130 = 21

-3x = 21

Divide each side by '-3'.

x = -7
