Answer:
(A) There should have been 5 outcomes of HT
(B) The experimental probability is greater than the theoretical probability of HT.
Step-by-step explanation:
Given
-- Sample Space
--- Sample Size
Solving (a); theoretical outcome of HT in 20 tosses
First, calculate the theoretical probability of HT


Multiply this by the number of tosses


<em></em>
Solving (b); experimental probability of HT
Here, we make use of the table


---- Experimental Probability
In (a), the theoretical probability is:

---- Experimental Probability
By comparison;

Answer:
x = 27
Step-by-step explanation:
The angle at any point on a straight line is 180 degrees.
The middle line over there is creating a right angle which is 90 degrees.
This must mean that both sides are 90 degrees.
3x+9 = 90
3x = 81
x = 27
$78 for each tire
4,992 divided by 64 is 78
