A Family has five children . The probability of having a girl is 1/2. What is the probability of having 2 girls followed by 3 bo

NeTakaya

Probability of having a girl: 1/2
Probability of having another girl right after: 1/2
Probability of having a boy right after: 1/2
Then another boy: 1/2
And a third boy: 1/2

To find compound probabilities, just multiply them together.

$\frac{1}{2}*\frac{1}{2}*\frac{1}{2}*\frac{1}{2}*\frac{1}{2} = \frac{1}{2*2*2*2*2} =\frac{1}{32} = \boxed{0.031}\ in\ decimal\ form$

How do you do this? -5x+y=-3 3x-8y=24

Katena32 [7]

$-5x+y=-3 \ \ \ |\times 8 \\
3x-8y=24 \\ \\
-40x+8y=-24 \\
\underline{3x-8y=24 \ \ \ \ \ \ \ } \\
-40x+3x=24-24 \\
-37x=0 \ \ \ |\div (-37) \\
x=0 \\ \\
3x-8y=24 \\
3 \times 0 -8y=24 \\
-8y=24 \ \ \ |\div (-8) \\
y=-3 \\ \\
\boxed{(x,y)=(0,-3)}$

Can someone pls explain how to do this

Rama09 [41]

The polynomial A is represented as x - 2, making option A the right choice.

In the question, we are asked to find the correct representation of A, when the algebraic expression (x² + x)/(x + 3) can be rewritten as the algebraic expression A + 6/(x + 3), where A is a polynomial.

Thus, we can write an equation,

A + 6/(x + 3) = (x² + x)/(x + 3),

or, A + 6/(x + 3) - 6/(x + 3) = (x² + x)/(x + 3) - 6/(x + 3) {Subtracting 6/(x + 3) from the both sides of the equation}

or, A = (x² + x)/(x + 3) - 6/(x + 3) {Simplifying},

or, A = (x² + x - 6)/(x + 3) {Subtracting the two fractions with the same denominator (x + 3)},

or, A = (x² + 3x - 2x - 6)/(x + 3) {Mid-term factorization},

or, A = {x(x + 3) - 2(x + 3)}/(x + 3) {Taking common},

or, A = {(x - 2)(x + 3)}/(x + 3) {Taking (x + 3) common},

or, A = x - 2 {Cancelling (x + 3) from the numerator and the denominator}.

Thus, the polynomial A is represented as x - 2, making option A the right choice.

What is the solution, vertex, and y-intercept of the graph? Please answer ASAP.

inna [77]

Graph is accurate enuf so that you can determine immed that the vertex / minimum is at (3,-4) and that the y-intercept is at (0,5).

If by "solutions" you mean "roots," the roots are {1, 5} (where y=0).
