Answer:
x^2 +y^2 -40x -24y -81 =0
Step-by-step explanation:
We can write the equation of a circle in the form
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
Assuming that Pamela's cabin is the center
( x-20)^2 + (y- 12)^2 = 25^2
We want to get to general form
x^2 + y^2 + Dx + Ey + F = 0,
Distributing
x^2 -40x +400 + y^2 -24y +144 = 625
x^2 +y^2 -40x -24y +544 -625 =0
x^2 +y^2 -40x -24y -81 =0
This will be false because that’s not the average winter temperatures in 45 states
So we have to put the value of 1:3 in a ratio
1 : 3
= 3:y
Ask yourself what do I have to multiply one by to get three ( the answer is three)
Because one side is multiplied by three, you have to multiply the right hand side by three to get y
3*3 is 9
Therefore, the y for 3 hours is 9
Then, we have to make another ratio
1:3
= 5:x
Ask yourself what do I have to multiply by one to get five (the answer is five)
So you multiply the other side by five as well
3*5=15
Therefore, the y for five hours is 15
I honestly don't know if this is right but it may make sense:
x is the event of picking up a rotten orange.
Probability that x is more than or equal to 1
= 1 - p(x=0)
so use binomialpdf on calculator
where trial is 4, p = 1/12(5/60), x = 0
1 - binoomialpdf(4, 1/12, 0)
and u get 0.294
In order to have a great experiment and great data for analyzing you must have the best experiment design possible.Experiment design is the process of organizing the experiment properly to ensure that the right type and amount of data are available to answer the questions of interest. Some of the tips to follow in order to have good experimental design are:
-Choose a topic that will interest and challenge you.<span>Do not pick a broad topic.
</span>- Spend a lot of time gathering background research.
<span>- Predict the outcome of your experiment with the help of equation.
</span>-Keep a detailed and up-to-date lab notebook with the results.
<span>- Do as many trials as possible .
</span><span>- During the experiment, do not get discouraged if you run into a lot of problems..</span>
