Solution:
The probability of a boy or a girl being born is . The probability of boys and girl being born is (0.5)^2(0.5)^1 =(0.5)^3 and the number of ways this can happen is C(2,1).
Therefore the probability of exactly boys and girl being born is C(2,1)(0.5)^3
.
C(2,1)(0.5)^3
since or %

Solved by pluggable solver: FIND a line by slope and one point

What we know about the line whose equation we are trying to find out: it goes through point (0, 9) it has a slope of -6 First, let's draw a diagram of the coordinate system with point (0, 9) plotted with a little blue dot: Write this down: the formula for the equation, given point and intercept a, is (see a paragraph below explaining why this formula is correct) Given that a=-6, and , we have the equation of the line: Explanation: Why did we use formula ? Explanation goes here. We are trying to find equation y=ax+b. The value of slope (a) is already given to us. We need to find b. If a point (, ) lies on the line, it means that it satisfies the equation of the line. So, our equation holds for (, ): Here, we know a, , and , and do not know b. It is easy to find out: . So, then, the equation of the line is: . Here's the graph:

Theorem 3.5 If two parallel lines are intersected by a transversal, then corresponding angles are congruent.

Given: line AB is parallel to line CD
Prove: Corresponding angles are congruent
Proof:


you have already learned vertical angles are congruent and corresponding angles are
congruent if they are formed by parallel lines
using this information we can go on to prove alternate interior angles are also congruent if they are formed by parallel lines

since the lines are parallel, than
< 1 and < 3 are congruent,
< 2 and < 3 are vertical angles
you have studied a theorem that states all vertical angles are congruent, so
that means < 1 congruent to < 3 because they are corresponding angles,
and < 2 congruent to < 3 because they are vertical angles,
that means < 1 must be congruent to < 3

The domain is all the values that x is allowed to take on.
The range is the set of all possible output values (usually y), which result from using the function formula.
example:
the domain and range of the following relation:
(–3, 5), (–2, 5), (–1, 5), (0, 5), (1, 5), (2, 5)
I'll just list the x-values for the domain and the y-values for the range:
domain: –3, –2, –1, 0, 1, 2
range: 5
Is the relation a function?

Yes, this is an example of a "boring" function:
every x-value (each is different) goes to the exact same y-value, but even so
this relation is a function that represents the horizontal line
