Probability of getting HH
1 answer:
<u>Answer:</u>
The experimental probability is 3% greater than the theoretical probability.
<u>Step-by-step explanation:</u>
We are given the results of flipping two coins with their outcomes and number of times they were tossed.
We are to compare the experimental and theoretical probability of getting HH.
The theoretical Outcomes are: HH HT TH TT
So theoretical probability of getting HH = = 25%
Total number of outcomes = = 100
So experimental probability of getting HH = = 28%
Therefore, the experimental probability is 3% greater than the theoretical probability.

Answer:
1. x=3 x=1
2. x=0
Step-by-step explanation:
We want f(x) to equal g(x)
f(x)=g(x)
1/(x-2) = (x-2)
Using cross products
1 = (x-2) * (x-2)
1 = x^2 -2x-2x+4
Subtract 1 from each side
1-1 = ^2 -2x-2x+4-1
0 = x^2 -4x+3
Factoring
What number multiplies to 3 and adds to -4
-3*-1 = 3
-3+-1 = -4
0= (x-3) (x-1)
Using the zero product property
x-3 =0 x-1=0
x=3 x=1
2. f(x)=x^2+4x+2
g(x)=(1/2)^ x+1
From the graph,we can see they intersect at x=0
