Answer:
x = 3
Step-by-step explanation:
You can use cross multiply.
8x = 6 x 4
8x = 24
x = 3
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

Step-by-step explanation:
Hi there!
Looking at the graph, we can see zeroes at x = -4, 0 (bounce, degree of 2) and 3. The graph is also face up, so it is positive. We can write an equation in factored form:
f(x) = x²(x + 4)(x - 3)
Find the equation of g by translating each zero left. The new zeros would be:
x = -6, x = -2, and x = 1
Write the polynomial:
g(x) = (x + 2)²(x + 6)(x - 1)
