The is a 50% chance of being a boy or a girl.....previous siblings do not matter. Every child is an independent event. So even if u had 2 siblings that were boys, the result of the next one being a boy is still gonna be 50%...just as the odds of it being a girl, is 50% as well.

Kim solved the equation below by graphing a system of equations. log base 2 (3x-1) = log base 4 (x+8)

kompoz [17]

Answer:

solution is

$x=1.353,y=1.613$

Step-by-step explanation:

We are given equation as

$log_2(3x-1)=log_4(x+8)$

Firstly, we will find equations

First equation is

$y=log_2(3x-1)$

Second equation is

$y=log_4(x+8)$

now, we can draw graph

and then we can find intersection point

we can see that

intersection point is (1.353,1.613)

so, solution is

$x=1.353,y=1.613$

Which of the following is a solution of x2 + 4x = −8?

Vladimir [108]

$x^{2}+4x = -8
\\\\
x^{2}+4x+8 = 0
\\\\
\Delta = b^{2}-4ac
\\\\
\Delta = (4)^{2}-4 \cdot (1) \cdot (8)
\\\\
\Delta = 16-32
\\\\
\Delta = -16$

There's no solution in the set of real numbers.

$\boxed{S = \{ \ \ \}}$

A number is randomly picked from this list: 10, 20, 30, 40, 50. what is the probability of picking an even number

ivanzaharov [21]

Hey there! :)

There are 5 numbers.

Even numbers end with 2, 4, 6, 8, or 0

All of the numbers end in 0

That means all the numbers are even

Your answer is: 5/5 = 1

Hope this helps :)
