Answer:

0.375

Step-by-step explanation:

The probability of having at least one girl out of 3 children can be calculated as;

P(1 girl, 2 boys) or P(2 girls, 1 boy) or P(3 girls)

Since the P(b) = P(g) = 1/2

Then the probability at any point in time is 1/2 * 1/2 * 1/2 = 1/8

So we have ;

1/8 + 1/8 + 1/8 = 3/8 = 0.375

Graph the functions as transformations of f ( x ) = x
ivolga24 [154]
Since the functions are not included, I can help you with some examples and a  general explanations which will help you to solve this kind of problems.


1) Assumption: all the functions that are considered are linear.


That means that f(x) = x is the parent function, and you can obtain the other functions by a set of transformations (translation and scalation) of the parent function.

2) Example 1: y = x + a


This is a special case of adding a constant to the function.

In this case, the graph of the new function is the graph of the parent function shifted a units upward.

3) Example: y = 5x

This is a special case of multiplying the function times a constant.

The result is streching the graph vertically by the same scale factor.

4) Example: y = (1/5)x - 8

In this case, the graph of y is obtained by scaling the parent function f(x) = x by 1/5 (which results in compressing the parent function vertically) and shifting the parent function 8 units downward.

Which expression is equivalent to the following complex fraction?
mamaluj [8]

The equivalent expression of 1 - \frac{1}{x} \div 2 is \frac{2x - 1}{2x}

<h3>How to determine the equivalent expression?</h3>

The expression is given as:

1 minus StartFraction 1 Over x EndFraction divided by 2

Rewrite properly as:

1 - \frac{1}{x} \div 2

Express the division as product

1 - \frac{1}{x} \times \frac 12

Evaluate the product

1 - \frac{1}{2x}

Take the LCM

\frac{2x - 1}{2x}

Hence, the equivalent expression of 1 - \frac{1}{x} \div 2 is \frac{2x - 1}{2x}

100 is 1/10 of what?
lawyer [7]

\boxed{ \ 100 \ is \ \frac{1}{10} \ of \ 1,000 \ }  

<h3>Further explanation  </h3>

The question can be rewritten to \boxed{ \ 100 \ is \ \frac{1}{10} \ of \ M \ }  

This case about equations with one variable. We have to solve this calculation to obtain the value of M. Our task is to isolate the variable M alone at the end of the process on one side of the equation until the variable will be equal to a value on the opposing side.  

Let's arrange it into an equation, i.e., \boxed{ \ 100 \ = \ \frac{1}{10} \times \ M \ }  

Turn this equation over so that the position of variable M is on the left side.  

\boxed{ \ M \times \frac{1}{10} = 100 \ }  

Both sides are multiplied by 10 to isolate M on the left side. The fraction are eliminated.  

\boxed{ \ M \times \frac{1}{10} \times 10 = 100 \times 10 \ }  

M = 1,000  

Therefore, we have calculated the number that was asked.  

Hence \boxed{ \ 100 \ is \ \frac{1}{10} \ of \ 1,000 \ }  

<u>Note:  </u>

The significant thing to carry out is how to manipulate both sides of the equation with the algebraic properties of equality such as:  

  • Adding  
  • Subtracting  
  • Multiplying, and/or  
  • Dividing both sides of the equation with a similar number

And the commutative property of multiplication, i.e., \boxed{ \ a \times b = b \times a \ }
