Answer:
x=−2, 2.6666
Step-by-step explanation:
Let's solve your equation step-by-step.
4=(1/2(2x+4+x))(x−2)
Step 1: Simplify both sides of the equation.
4=3/2 x2−x−4
Step 2: Subtract 3/2x^2-x-4 from both sides.
4−(3/2 x2−x−4)=
3/2 x2−x−4−(3/2 x2−x−4)
−3/2 x2 +x+8=0
For this equation: a=-1.5, b=1, c=8
−1.5x2+1x+8=0
Step 3: Use quadratic formula with a=-1.5, b=1, c=8.
x=−b±√b2−4ac
2a
x=−(1)±√(1)2−4(−1.5)(8)
2(−1.5)
x=−1±√49
−3
x=−2,2.66666666666666666666666666666
Answer:
The experimental probability --> 
The theoretical probability --> 
Step-by-step explanation:
<u>Key skills needed: Experimental vs theoretical probability, Fractions</u>
1) The first thing you need to understand is experimental probability vs theoretical probability. (Do not include this in your work!!)
- Theoretical probability is based on simple reasoning
- Experimental probability is based on the results a person gets (so the experiment you did by flipping the coin)
2) Now with this, let's start solving:
- Experimental probability --->
--> You flipped the coin a total of 100 times, so the denominator would be 100. 65 of those would be heads so 65 is our numerator. - So our experimental probability is -->
--> Both have the factor of 5, so take the factor of 5 out of the numerator and denominator and you will get --> - Now onto theoretical probability --> --> There are 2 faces of a coin, 1 side is heads, and 1 side is tails --> The total number of faces is 2, so 2 is our denominator. There is only 1 side that is heads, so 1 is the numerator. This means --> Our theoretical probability is
<em>Hope you understood and have a nice day!! :D</em>
To solve for x, you simplify both sides of the equation and then isolate the variable.
<em>10x + 12 = $72.00</em>
<em>x = 6</em>

Hello there!
The square root of 100 is 10
√100 = 10
As always, it is my pleasure to help students like you!
Will there's
5.5 x 2 = 11
hope that helped
