I have chosen 1 playing card. what is the probability of being red or red ace?

1 answer:

3 0

Answer: 26/52 or 0.5 or 50%

Step-By-Step:
So since there are 52 cards in a deck and half of them are red which does include the red ace that means you have 26/52 probability. The red aces are already including in this half of the deck and sense it is an or statement we do not need to add it back into the probability.

What are the factors of 5^24 that are both square and cube. Leave answer In factorised index form

DaniilM [7]

Remember
$(x^a)^b=x^{ab}$
and

so maybe we want to find a and b such that $a^2=b^3=5^{24}$

24/2=12, so 12*2=24 so $5^{24}=5^{12*2}=(5^{12})^2$
24/3=8, so 8*3=24 so $5^{24}=5^{8*3}=(5^8)^3$
so
$(5^{12})^2=(5^8)^3=5^{24}$

I think those are in factored index form

Solve the following system of equations by substitution. Show all steps.

Alinara [238K]

Answer:

Given system of equations:

$\begin{cases}f(x)=-x^2+2x+3\\g(x)=-2x+3\end{cases}$

To solve by substitution, equate the equations and solve for x:

$\begin{aligned}f(x) & = g(x)\\\implies -x^2+2x+3 & = -2x+3\\-x^2+4x & = 0\\x^2-4x & = 0\\x(x-4) & = 0\\\implies x & = 0\\\implies x-4 & = 0 \implies x=4\end{aligned}$

Therefore, the x-values of the solution are $x = 0$ and $x = 4$ .

To find the y-values of the solution, substitute the found values of x into the functions:

$f(0)=-(0)^2+2(0)+3=3$

$g(0)=-2(0)+3=3$

$f(4)=-(4)^2+2(4)+3=-5$

$g(4)=-2(4)+3=-5$

Therefore, the solutions to the given system of equations are:

$(0, 3)$ and $(4, -5)$

(07. 01)How many solutions can be found for the equation 4x = 4x? Zero One Two Infinitely many.

AlexFokin [52]

The given equation have infinitely solution.

we have given that equation 4x=4x

<h3>What are the condition for solution no solution one solution infinite solution?</h3>

Zero solution:-No solution would mean that there is no answer to the equation

One solution:-There is only one value for the variable that makes the equation true.

Two solution:-A quadratic equation with real or complex coefficients has two solutions, called roots. These two solutions may or may not be distinct, and they may or may not be real.

infinitely solution:- Infinite solutions would mean that any value for the variable would make the equation true.(x=x)

Given equation have infinitely many solution because there are so many different ways that can be found.

Therefore we have the given equation have infinitely solution
