Answer:
TP = 5. greater than
Step-by-step explanation:
1. Out of the 4 options, HH, HT, TH, TT, there is one option we want (HT) which is one our of the four options. that means that the theoretical probability is 1/4 = 25%. Since there were 20 flips, the theoretical probability is 25% of 20 which is 5.
2. For experimental probability, its what actually happenned. Out of the 20 flips, 6 were HT so comapared to the Theoretical probability, the experimental probability was higher.
((x+2)(x+2))-((x-5)(1))=A
x^2+4x+4-x+5=A
x^2+3x+9=A
Answer:
D,1

Answer:
<em>i: </em>x=-2, x=1
<em>ii: </em>x=-1/2
Step-by-step explanation:
Quadratic form:
You solve <em>i </em>by using FOIL (First, Outside, Inside, Last) because it is a multiplication problem.

<em>"first"</em> would be
, which would equal 
<em>"outside"</em> would be
, which would equal 
<em>"inside"</em> would be
, which would equal 
<em>"last" </em>would be
, which would equal 
Now you need to combine the terms so that they are one after the other

Combine like terms, and you should get:

i Solution
<em>You need to get the variable by itself.</em>
<em>Subtract two from both sides</em>

<em>Add one to both sides.</em>

ii Solution
<em>Add all the terms.</em>

Two events are mutually exclusive if they cannot occur in the same trial of an experiment.
