Answer:

B) 0.06

Step-by-step explanation:

This will make the fourth child; we want the probability that all 4 children are girls.

The probability of having a girl with each child is independent; this means that having 1 girl does not affect your chances of having another girl.

This means the probabilities can be multiplied:

0.5(0.5)(0.5)(0.5) = 0.0625

What is the exact radian measure of an angle of 132
Pepsi [2]
Since we know that in π radians there are 180°, thus how many radians in 132°?

\bf \begin{array}{ccll}
de grees&radians\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
180&\pi \\
132&x
\end{array}\implies \cfrac{180}{132}=\cfrac{\pi }{x}\implies x=\cfrac{132\cdot \pi }{180}\implies \stackrel{simplified}{\cfrac{11\pi }{15}}

When 142 is added to a number, the result is 64 more than 3 times the number. Find
dmitriy555 [2]
X+142 =3x+64

subtract x from each side

142 = 2x+64

subtract 64 from each side

142-64 = 2x

78=2x

divide by 2

78/2 = x

x=39

The number is 39
