"and" means summe
P(coin)+P(cube)=1/2+1/6=0,666667
The chance to get head is always 1/2 no matter how often you toss the coin
And the chance to get a number when you roll a number cube is always 1/6

Did you mean that?

 <span>there are 12 possible outcomes. 
Heads - 1 
Heads - 2 
Heads - 3 
Heads - 4 
Heads - 5 
Heads - 6 
Tails - 1 
Tails - 2 
Tails - 3 
Tails - 4 
Tails - 5 
Tails - 6 

You want heads AND an even number, so that narrows it down to three. 
Heads - 2 
Heads - 4 
Heads - 6 

So thats 3/12 chance, which is simply a 25.00 percent chance. 


Much simper way to do so is that are 4 outcomes if you don't count the numbers. 
Heads - Even 
Heads - Odd 
Tails - Even 
Tails - Odd 

so you can also get 25.0% that way.</span>

Consider the inequality -5(x+7)&lt;-10 Write an inequality representing the solution for x
Naddik [55]
-5(x+7)<-10
-5x-35<-10
+35. +35
-4x<25
both divided by-4
x> -6.25
i flipped the sign because I divided with a negative number. and I hope you can make -6.25 into a fraction, I can't because I don't have a calculator with me :(

Hello, how was your day, help? ^ ^<br> solve for x
Natali5045456 [20]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

\boxed{x=100}

»»————- ★ ————-««  

Here’s why:  

  • Recall the Triangle Angle Sum Theorem: The three angles of all triangles add up to a sum of 180°.
  • We will set up an equation based on this and then solve.

⸻⸻⸻⸻

\boxed{\text{Solve for 'x':}}\\\\58 + 22 + x = 180\\-----------\\\rightarrow 80 + x = 180\\\\\rightarrow 80 - 80 + x = 180 - 80\\\\\rightarrow \boxed{x=100}

⸻⸻⸻⸻

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.

For any number n&gt;1 is |(3/4+2/3i)^n|
sasho [114]

The for any number n>1 is |(3/4+2/3i)^n| greater than 1 after simplifying the complex number.

<h3>What is a complex number?</h3>

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

We have a complex number:

= \rm |(\dfrac{2}{3}+\dfrac{3}{4}i)^n|\\\\\\= \rm |(\dfrac{8+9i}{12})^n|\\\\\\= \rm |\dfrac{(8+9i)^n}{12^n}|\\\\

Here n>1

Plug n = 2

= \rm |\dfrac{(8+9i)^2}{12^2}|\\\\

= 145/144

= 1.0069

Which is greater than 1.

Thus, the for any number n>1 is |(3/4+2/3i)^n| greater than 1 after simplifying the complex number.
