Why does this not exist? I thought if you plugged in infinity, you would just get infinity. Do you not plug in infinity?
Answers
Answer:
See below
Step-by-step explanation:
It does not exist because the
[tex](-1)^x[/tex]
doesn't tend to some value it just loop around
[tex]-1, 1[/tex]
for ever
it exist when we have
[tex]\lim_{x\rightarrow \infty}[(\frac{1}{x})][/tex]
there when the value of x increasing the fractions tends to 0
so we can say that when x approaches infinity the value is 0.

Step-by-step explanation:
It was Robin's birthday and she knew she was going to have a good day. She was driving to work, and when she turned on the radio, her favorite song was playing. Besides, the traffic light at the main intersection she crossed to get to work was green when she arrived, something that seemed to happen less than once a week. When she arrived at work, rather than having to search as she usually did, she found an empty parking space right in front of the building. Identify three random circumstances in the story, and give the possible outcomes for each of them. (Select all that apply.)
Answers
Answer:
1.Random circumstance: Color of traffic light when Robin approaches the main intersection. Possible outcomes: Traffic light is green when Robin arrives, or Traffic light is not green when Robin arrives.
2.Random circumstance: Song on the radio when first turned on. Possible outcomes: Robin's favorite song is playing, or Robin's favorite song is not playing.
4.Random circumstance: Nearest available parking space. Possible outcomes: Robin finds an empty parking space in front of the building, or Robin does not find an empty parking space in front of the building.
Step-by-step explanation:
A random circumstance is one whose outcome cannot be predicted because we either do not have the full details of the matter or it has not been confirmed yet by a reliable source. In the short description of events provided above;
1.The color of the traffic light is unpredictable because it is not under the control of the drivers but is automated.
2. Robin's favorite song playing on the radio is a random circumstance because she has no control over what song is played. So, she might as well have tuned in and it would be her least favorite song playing.
3. Robin driving into the office and finding the parking space empty is a random circumstance because it is not predictable. She might have come in and found the entire space filled.

We know that the blue triangle is the image as it has the ' on the letters. For example G'.
To first start off, you can look at any points to help solve this problem. I used the point H to help me solve this
Since we know that the black triangle is our old image we know the distance in x values between the black triangle to the blue is -2 as it moves to the left 2 times. (Note: it's going more into the negatives, if it were going to the right it would be positive)
Now we do the same to find our y values, and we see that y value for h on the black triangle goes up +1.
Now we know that the X goes to the left two times to get -2 and that the Y goes up once to get +1.
Hope this helps! :)
Answer:
b. (x - 2, y + 1)
Step-by-step explanation:
You can make that determination visually. However, if you need numbers...
Pick a point on the black triangle, let's say F(0, 0) and the corresponding point on the blue tirangle F(-2, 1)
(y₁ + y₂) / (x₁ + x₂) = (0 + 1) / (0 + (-2)) = 1 / -2
[tex]\frac{rise}{run}[/tex] = [tex]-\frac{1}{2}[/tex]
So, from the F(0,0) position move -2 to the left then up 1 to land on F(-2, 1).
This translated to (x - 2, y + 1)
A large automobile insurance company selected samples of single and married male policyholders and recorded the number who made an insurance claim over the preceding three-year period.
Single Policyholders Married Policyholders
n1 = 500 n2 = 800
Number making claims = 95 Number making claims = 80
(a) Use a level of significance a = 0.05. Test to determine whether the claim rates differ between single and married male policyholders. Explain your determination.
(b) Provide a 95% confidence interval for the difference between the proportions for the two populations.
Answers
Answer:
a
The determination is
There is sufficient to conclude that proportion of the single policy
b
The 95% confidence interval is [tex] 0.0498 < p_1 - p_2 < 0.1302 [/tex]
holders is difference from the proportion of married policy holders
Step-by-step explanation:
From the question we are told that
The sample size for single policy holders is [tex]n_1 = 500[/tex]
The number of single police holders making claim is k = 95
The sample size for married policy holders [tex]n_2 = 800[/tex]
The number of double police holders making claim is u = 80
The level of significance is [tex]\alpha = 0.05[/tex]
Generally the critical value of [tex]\frac{\alpha }{2}[/tex] obtained from the
normal distribution table is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
The null hypothesis is [tex]H_o : p_1 = p_2[/tex]
The alternative hypothesis is [tex]H_a : p_1 \ne p_2[/tex]
The sample proportion of single police holders making claim is
[tex]\r p_ 1 = \frac{k}{n_1}[/tex]
=> [tex]\r p_ 1 = \frac{95}{500}[/tex]
=> [tex]\r p_ 1 = 0.19[/tex]
The sample proportion of married police holders making claim is
[tex]\r p_ 2 = \frac{u}{n_2}[/tex]
=> [tex]\r p_ 2 = \frac{80}{800}[/tex]
=> [tex]\r p_ 2 = 0.1[/tex]
Generally the pooled sample proportion is mathematically represented as
[tex]\r p = \frac{k + u}{n_1 + n_2}[/tex]
=> [tex]\r p = \frac{95 + 80}{500 + 800}[/tex]
=> [tex]\r p = 0.1346 [/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{\r p_1 - \r p_2 }{ \sqrt{ \r p (1 - \r p )* [\frac{1}{n_1} + \frac{1}{n_2} ]} }[/tex]
=> [tex]z = \frac{0.19 - 0.1 }{ \sqrt{0.1346 (1 - 0.1346 )* [\frac{1}{500} + \frac{1}{800} ]} }[/tex]
=>[tex]z = 4.6256 [/tex]
Generally the p-value is mathematically represented as
[tex]p-value = 2* P(Z >4.6256 )[/tex]
From the z table [tex]P(Z >4.6256 ) = 0 [/tex]
[tex]p-value = 2* 0 = 0[/tex]
From the calculation we see that the p-value < [tex]\alpha[/tex] so the null hypothesis is rejected
Hence there is sufficient to conclude that proportion of the single policy holders is difference from the proportion of married policy holders
Generally the standard error is mathematically represented as
[tex]SE = \sqrt{ \frac{\r p_1 (1 -\r p_1)}{n_1} + \frac{\r p_2 (1 -\r p_2)}{n_2} }[/tex]
=> [tex]SE = \sqrt{ \frac{0.19 (1 -0.19)}{500} + \frac{ 0.1 (1 - 0.1)}{800} }[/tex]
=> [tex]SE =0.0205012[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * SE[/tex]
=> [tex]E = 1.96 *0.0205012 [/tex]
=> [tex]E = 0.0402035[/tex]
Generally the 95% confidence level is mathematically represented as
[tex]\r p_1 - \r p_2 - E < p_1 - p_2 < \r p_1 - \r p_2 + E[/tex]
=> [tex]0.19 - 0.10 -0.0402035 < p_1 - p_2 < 0.19 - 0.10 + 0.0402035 [/tex]
=> [tex]0.09 -0.0402035 < p_1 - p_2 < 0.09 + 0.0402035 [/tex]
=> [tex] 0.0498 < p_1 - p_2 < 0.1302 [/tex]

To reduce laboratory costs, water samples from five public swimming pools are combined for one test for the presence of bacteria. Further testing is done only if the combined sample tests positive. Based on past results, there is a 0.007 probability of finding bacteria in a public swimming area. Find the probability that a combined sample from five public swimming areas will reveal the presence of bacteria. Is the probability low enough so that further testing of the individual samples is rarely necessary?
Answers
Answer:
Step-by-step explanation:
Given that:
The numbers of the possible public swimming pools are 5
From past results, we have 0.007 probability of finding bacteria in a public swimming area.
In the public swimming pool, the probability of not finding bacteria = 1 - 0.007
= 0.993
Thus;
Probability of combined = Probability that at least one public
sample with bacteria swimming area have bacteria
Probability of combined sample with bacteria = 1 - P(none out of 5 has
bacteria)
Probability of combined sample with bacteria = 1 - (0.993)⁵
= 1 - 0.9655
= 0.0345
Thus, the probability that the combined sample from five public swimming areas will show the presence of bacteria is 0.0345
From above, the probability that the combined sample shows the presence of bacteria is 0.0345 which is lesser than 0.05.
Thus, we can conclude that; Yes, the probability is low enough that there is a need for further testing.
