Answer:
$300,000
Step-by-step explanation:
To find 8% of 100,000 all you need to do is multiply 100,000 by .08.
100,000 (.08) = 8,000
The 8,000 accounts for one year, so now you have to multiply 8,000 by 25.
8,000 (25) = 200,000
Now add the initial amount to the additional 200,00 that will be paid to the retirement account.
100,000 + 200,000 = 300,000
The answer is $300,000.

Answer: 10,000
Step-by-step explanation: here's how I got my answer:
Since we are finding the decrease from 2005-2015, we need to multiply 1/20 by 10, since the timespan is 10 years worth of decreasing.
So, 1/2 * 10 =1/2
So, since we have 1/2 as the overall decrease in the population within the 10 years, we divide 20,000 by 1/2 or 20,000 by 2, and we get 10,000. I hope this helps.

How did the United States' entry into World War I change the culture and
international political policies of the country?
The United States' entry into World War I led to a rise in nationalism and patriotism, as well as a shift towards a more interventionist foreign policy. This had a lasting impact on the culture and international political policies of the country.
Explanation:The United States' entry into World War I marked a significant shift in the culture of the country. Prior to the war, the United States had maintained a policy of isolationism, with a focus on avoiding involvement in foreign conflicts. However, the country's entry into the war marked a shift towards a more interventionist foreign policy, as the United States began to take a more active role in international affairs.
HOPE IT HELPS!Donna wants to draw a right triangle. She wants the hypotenuse to be 1.5 inches long and one of the legs to be 1.2 inches long. Enter the length that she must use for the second leg to form a right triangle.
Answer:
0.9 inches
Step-by-step explanation:
The sides of right triangles follow the Pythagorean Theorem:
a² + b² = c²
"a" and "b" are the two shorter sides and "c" is the hypotenuse, the longest side.
Let's plug in what we know.
a² + b² = c²
(1.2)² + b² = (1.5)²
Let's solve the exponents.
1.44 + b² = 2.25
Subtract 1.44 from both sides.
b² = 0.81
Take the square root of both sides.
√b² = √0.81
b = 0.9
The second side will be 0.9 inches.

The members of a consulting firm rent cars from three rental agencies. It is estimated that 0.42 percent of cars come from agency 1, 0.08 percent of cars come from agency 2, and 0.5 percent of cars come from agency 3. It is also estimated that 0.08 percent of cars from agency 1 need a tune-up, 0.02 percent of cars from agency 2 need a tune-up, and 0.02 percent of cars from agency 3 need a tune-up. Answer the following questions, rounding your answers to two decimal places where appropriate.
The probability that a rental car delivered to the firm will need a tune-up is 0.05% and the conditional probability is 0.04%
How to determine the probabilitiesThe probability that a rental car delivered to the firm will need a tune-up
From the question, we have the following parameters that can be used in our computation:
Agency 1 = 0.42%, Tune up from agency 1 = 0.08%
Agency 2 = 0.08%, Tune up from agency 2 = 0.02%
Agency 3 = 0.5%, Tune up from agency 3 = 0.02%
Using total probability, we have the following equation
P(tune-up) = P(tune-up | agency 1) * P(agency 1) + P(tune-up | agency 2) * P(agency 2) + P(tune-up | agency 3) * P(agency 3)
Substitute the known values in the above equation, so, we have the following representation
P(tune-up) = 0.08% * 0.42% + 0.02% * 0.08% + 0.02% * 0.5%
Evaluate the sum of products
P(tune-up) = 0.000452
Express as percentage and approximate
P(tune-up) = 0.05%
(b) The probability that it came from agency 2
This is a conditional probability, and it calculated as
P(Agency 2| Tune up) = P(Tune up and Agency 2)/P(Tune up)
Substitute the known values in the above equation, so, we have the following representation
P(Agency 2| Tune up) = (0.02% * 0.08%)/0.0452%
Evaluate
P(Agency 2| Tune up) = 0.0003539823
Express as percentage
P(Agency 2| Tune up) = 0.03539823%
Approximate
P(Agency 2| Tune up) = 0.04%
So, the probability is 0.04%

The price of an item has risen to $387 today. Yesterday it was $180. Find the percentage increase
Answer:
115%
Step-by-step explanation:
Given that,
The initial price of an item = $180
The final price of an item = $387
We need to find the percentage increase. It can be calculated as follows :
[tex]\%=\dfrac{\text{Change in price}}{\text{initial price}}\times 100[/tex]
Put all the values,
[tex]\%=\dfrac{387-180}{180}\times 100\\\\=115\%[/tex]
So, the required percentage increase is 115%.
Researchers at the National Cancer Institute released the results of a study that investigated the effect of weed-killing herbicides on house pets. The randomly sampled 400 dogs from homes where an herbicide was used on a regular basis, diagnosing lymphoma in 230 of them. Of 200 dogs randomly sampled from homes where no herbicides were used, only 25 were found to have lymphoma. For this problem, let p1 be the population proportion of dogs that get lymphoma from homes where herbicides are used and p2 be the population proportion of dogs that get lymphoma from homes where herbicides are not used. Researchers are interested in learning about the difference in the proportion of cancer diagnoses between the two groups. What is the 95% confidence interval for the difference in the proportion of cancer diagnoses between the two groups
Answer:
The 95% confidence interval for the difference in the proportion of cancer diagnoses between the two groups is (0.3834, 0.5166).
Step-by-step explanation:
Before building the confidence interval, we need to understand the central limit theorem and subtraction between normal variables.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
Subtraction between normal variables:
When two normal variables are subtracted, the mean is the difference of the means, while the standard deviation is the square root of the sum of the variances.
The randomly sampled 400 dogs from homes where an herbicide was used on a regular basis, diagnosing lymphoma in 230 of them.
This means that:
[tex]p_h = \frac{230}{400} = 0.575, s_h = \sqrt{\frac{0.575*0.425}{400}} = 0.0247[/tex]
Of 200 dogs randomly sampled from homes where no herbicides were used, only 25 were found to have lymphoma.
This means that:
[tex]p_n = \frac{25}{200} = 0.125, s_n = \sqrt{\frac{0.125*0.875}{200}} = 0.0234[/tex]
Distribution of the difference:
[tex]p = p_h - p_n = 0.575 - 0.125 = 0.45[/tex]
[tex]s = \sqrt{s_h^2+s_n^2} = \sqrt{0.0247^2 + 0.0234^2} = 0.034[/tex]
Confidence interval:
The confidence interval is:
[tex]p \pm zs[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The lower bound is [tex]0.45 - 1.96(0.034) = 0.3834[/tex]
The upper bound is [tex]0.45 + 1.96(0.034) = 0.5166[/tex]
The 95% confidence interval for the difference in the proportion of cancer diagnoses between the two groups is (0.3834, 0.5166).

1. The ratio of fiction books to the non fiction books, if there are 4 fiction books to 5 non fiction books
2. The ratio of marker to crayon , if there are 4 markers and 5 crayons. ( option A and D)
What is ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls.
For a scenario that will give ratio of 4:5, it means the first entity will be 4 and the second entity will be 5.
Therefore the two statements that obey this in the option are
1. The ratio of fiction books to the non fiction books, if there are 4 fiction books to 5 non fiction books
2. The ratio of marker to crayon , if there are 4 markers and 5 crayons.
