Answer:
1)The theoretical probability that a coin toss results in two heads showing is 25%.
2)The experimental probability that a coin toss results in two heads showing is 44%.
3) The theoretical probability that a coin toss results in two tails showing is 25%.
4) The experimental probability that a coin toss results in two tails showing is 34%.
5) The theoretical probability that a coin toss results in one head and one tail showing is 50%.
6) The experimental probability that a coin toss results in a head and a tail is 22%.
7) The experimental probabilities are slightly different from the theoretical probabilities because the number of experiments is relatively small. As the number of experiments increase, the experimental probabilities will get closer to the theoretical probabilities.
Step-by-step explanation:
Probability:
What you want to happen is the desired outcome.
Everything that can happen iis the total outcomes.
The probability is the division of the number of possible outcomes by the number of total outcomes.
Theoretical Probability:
The results you expect to happen.
Experimental Probability:
The probability determined from the result of an experiment.
1. What is the theoretical probability that a coin toss results in two heads showing?
In each toss, the theoretical probability that a coin toss results in a head showing is 50%.
So for two coins, the probability is:
The theoretical probability that a coin toss results in two heads showing is 25%.
2. What is the experimental probability that a coin toss results in two heads showing?
There were 100 flips, and it resulted in two heads 44 times, so:
The experimental probability that a coin toss results in two heads showing is 44%.
3. What is the theoretical probability that a coin toss results in two tails showing?
In each toss, the theoretical probability that a coin toss results in a tail showing is 50%.
So for two tails, the probability is:
The theoretical probability that a coin toss results in two tails showing is 25%.
4. What is the experimental probability that a coin toss results in two tails showing?
There were 100 flips, and it resulted in two tails 34 times, so:
The experimental probability that a coin toss results in two tails showing is 34%.
5. What is the theoretical probability that a coin toss results in one head and one tail showing?
In each toss, the theoretical probability that a coin toss results in a tail showing is 50% and in a head showing is 50%.
They can be permutated, as the tail can appear before the head, or the head before the tail. So:
The theoretical probability that a coin toss results in one head and one tail showing is 50%.
6. What is the experimental probability that a coin toss results in one head and one tail showing?
There were 100 flips, and it resulted in a head and a tail showing 22 times, so:
The experimental probability that a coin toss results in a head and a tail is 22%.
<u><em>a=1/100pt is the correct answer.</em></u> First you had to multiply by t from both sides of equation, and it gave us, ⇒ . And then you had to flip an equation, and it gave us, ⇒
. You can also divide by one-hundred (100) from both sides of equation, and it gave us,
. And finally, and it gave us the answer is a=1/100pt is the final answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
Answer:
A line passing through the points (-1,-4),(0,0) and (1,4)
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
<u><em>Verify each case</em></u>
Part 1) A line passing through the points (-4,0) and (0,-2)
This line not represent a direct variation, because the line not passes through the origin.
Part 2) A line passing through the points (-5,4) and (0,3)
This line not represent a direct variation, because the line not passes through the origin.
Part 3) A line passing through the points (-4,-6) and (0,3)
This line not represent a direct variation, because the line not passes through the origin.
Part 4) A line passing through the points (-1,-4),(0,0) and (1,4)
The line passes through the origin
Find out the value of k
For the point (-1,-4)
substitute
For the point (1,4)
substitute
The linear equation is
This line represent a direct variation
