A fair coin is flipped 10 times and lands on heads 8 times. Why is there a difference between the experimental and theoretical probabilities of observing 8 heads in 10 coin flips?
A.
Since the number of heads in the 10 coin flips is 8, the theoretical probability of observing a head in a coin flip increases from 0.5 to 0.8.
B.
Since 10 is a large enough number of trials, there is probably some error in the recording of the coin flip outcomes.
C.
The theoretical probability has no basis in reality, so the new probability of flipping heads is now 0.8.
D.
There should be a larger number of trials. With 500 flips of the coin, the experimental probability will likely approach the theoretical probability of 0.5.

HELP ME PLEASE The roots of a quadratic equation can be found using the graph what are the roots of these equations?
Answer:
the roots of this quadratic expression are: x = -1 and x = 4
Step-by-step explanation:
You need to find at which x-values the graph crosses the x-axis (this is when y = 0, and therefore the roots of the quadratic equation represented via the graph).
In our case notice that the graph crosses the x-axis at the points:
x = -1 (on the left), and x = 4 (on the right)
Therefore the roots of this quadratic expression are: x = -1 and x = 4.

11 more than x is less than. 3 (please)
Answer:
(11+x)-3
Step-by-step explanation:
11 more than x is another way of saying 11+x
And "less than 3" means subtracting 3 from the terms
So if you put that together it would be
(11+x) -3

Enter your answer in the box
39
X=
102°
Answer:
x=39
Step-by-step explanation:
The interior angles add up to 180 degrees so you do 39+102, which is 141. Then you subtract 141 from 180 and then you get 39 degrees.
The triangles are similar. Solve for x. Hint - draw the triangles separately.
Answer:
The answer is 18
Step-by-step explanation:
All you have to do is look at the length the left side of the triangle and see what you have to divide the larger number by to get the smaller number.
Then you have to divide the number on the bottom by the number that you had to divide the larger number by the side by.

change 4 and 4 on 9 to an improper fraction
Answer: 40/9
Step-by-step explanation:
First multiply the number 4 and the denominator 9 together which is 36 in this case. Then add the remaining 4 which takes you to 40 then the denominator will stay the same so the answer will be 40/9
