There is a 50% chance a coin lands on heads and a 50% chance the coin lands on tails what is the probability that the coin lands

Olegator [25]

Since the probability of the coin landing leads is 1/2, simply cube 1/2 to arrive at your answer: 1/8.

You cube 1/2 because you must land heads three times in a row and each flip is independent from other flips.

1) Has zeros at -2 and 4, both being double roots<br><br> 2) As x→∞, y→−∞

irina1246 [14]

-(x+2)^2(x-4)^2

Not that if x= -2 and x=4 they will look like this in an equation: (x+2) and (x-4)
When (x+2) and (x-4) are set equal to zero and you solve for x, x will equal x= -2 and x=4

If they have double roots, they have a multiplicity of 2 (per root) meaning they will bounce off of the x-axis. Multiplicity can be found by using exponents.

The negative in front flips the function over the x-axis and holds true to the given limit.

How many solutions does the system of equations have? Pls help :(

goldfiish [28.3K]

Given the system of equations below:

$\large{ \begin{cases} y = 2x + 1 \\ - 4x + 2y = 2 \end{cases}}$

The first equation is y-isolated so we can substitute in the second equation.

$\large{ - 4x + 2(2x + 1) = 2}$

Use the distribution property to expand in and simplify.

$\large{ - 4x + 4x + 2 = 2} \\ \large{0 + 2 = 2 \longrightarrow 2 = 2}$

The another method is to divide the second equation by 2.

$\large{ \frac{ - 4x}{2} + \frac{2y}{2} = \frac{2}{2} } \\ \large{ - 2x + y = 1}$

Arrange in the form of y = mx+b.

$\large{y = 1 + 2x \longrightarrow y = 2x + 1}$

When we finally arrange, compare the equation to the first equation. Both equations are the same which mean that both graphs are also same and intersect each others infinitely.

For more information, when the both sides are equal for equation - the answer would be infinitely many. If both sides aren't equal (0 = 4 for example) - the answer would be none. If the equation can be solved for a variable then it'd be one solution.

Answer

Infinitely Many

Hope this helps. Let me know if you have any doubts!
