Ben is 12 years older than Ishaan. Ben and Ishaan first met two years ago. Three years ago, Ben was 4 times as
old as Ishaan.
How old is Ishaan now?
Answer:
Ishaan is now 6.
Step-by-step explanation:
If Ben is 12 years older, and you have the info that three years ago, he was 4 times as old, then all you have to do is divide 12 by 4, giving you 3. You add 3 to that because it's been three years. You have your answer of 6.

(xy^2+x)dx + ( yx^2+y )dy =0
Answer:
(y^2+1)(x^2+1)=k
Step-by-step explanation:
It looks like it is possibly separatable.
Let's try.
Factor the x out on first term and factor the y out on second term:
x(y^2+1)dx+y(x^2+1)dy=0
Subtracting y(x^2+1)dy on both sides:
x(y^2+1)dx=-y(x^2+1)dy
Divide both sides by (y^2+1)(x^2+1):
x/(x^+2+1)dx=-y/(y^2+1)dy
Integrate both sides..
Use substitution u=x^2+1 and v=y^2+1...so du= 2x dx and dv=2y dy.
.5du/u=-.5dv/v
.5ln|u|=-.5ln|v|+c
Multiply both sides by 2:
ln|u|=-ln|v|+c
Plug in our substitutions :
ln|x^2+1|=-ln|y^2+1|+c
Absolute values unnecessary since insides are positive always.... also -ln(y^2+1)=ln(1/(y^2+1))
e^ on both sides:
x^2+1=k(1/y^2+1)
(y^2+1)(x^2+1)=k

2. mr. voss and mr. cull bowl every tuesday night. over the past few years, mr. voss's scores have
been approximately normally distributed with a mean of 212 and a standard deviation of 31.
during the same period, mr. cull's scores have also been approximately normally distributed with
a mean of 230 and a standard deviation of 40. assuming their scores are independent, what is the
probability that mr. voss scores higher than mr. cull on a randomly-selected tuesday night?
The probability that Mr. Voss scores higher than Mr. Cull on a randomly-selected Tuesday night can be calculated using the Normal Distribution.
To calculate the probability that Mr. Voss scores higher than Mr. Cull on a randomly-selected Tuesday night, we can use the Normal Distribution. First, we need to calculate the difference between their means, which is 18. Then, we need to calculate the standard deviation of the difference between their scores, which is the square root of the sum of the squares of their standard deviations (√(31²+40²) = 51.96). To calculate the probability, we use the z-score formula, which is (x - mean) / standard deviation. In this case, the z-score is (18 - 0) / 51.96 which is 0.35. Plugging this z-score into a z-table, we get a probability of 0.6379. Therefore, the probability that Mr. Voss scores higher than Mr. Cull on a randomly-selected Tuesday night is 0.6379.
The complete question: Mr. Voss and Mr. Cull bowl every Tuesday night. Over the past few years, Mr. Voss’s scores have been approximately Normally distributed with a mean of 212 and a standard deviation of 31. During the same period, Mr. Cull’s scores have also been approximately Normally distributed with a mean of 230 and a standard deviation of 40. Assuming their scores are independent, what is the probability that Mr. Voss scores higher than Mr. Cull on a randomly-selected Tuesday night?

Compute the population mean. (Round your answer to 1 decimal place.) b. Compute the standard deviation. (Round your answer to 2 decimal places.) c. If you were able to list all possible samples of size five from this population of 20, how would the sample means be distributed
Using the concepts of mean and standard deviation, and the central limit theorem, it is found that:
a. The mean is of: 3.3
b. The standard deviation is of: 1.23.
c. They would have a mean of 3.3 and a standard deviation of 0.55.
What are the mean and the standard deviation of a data-set?The mean of a data-set is given by the sum of all values in the data-set, divided by the number of values.The standard deviation of a data-set is given by the square root of the sum of the differences squared between each observation and the mean, divided by the number of values.For this problem, the mean is given by:
M = (2 + 3 + 2 + 3 + 3 + 4 + 2 + 4 + 3 + 2 + 2 + 7 + 3 + 4 + 5 + 3 + 3 + 3 + 3 + 5)/20 = 3.3
The standard deviation is:
\(S = \sqrt{\frac{(2 - 3.3)^2 + (3 - 3.3)^2 + \cdots + (3 - 3.3)^2 + (5 - 3.3)^2}{20}} = 1.23\)
What does the Central Limit Theorem states?It states that for distribution of sample means of size n:
The mean remains constant.The standard deviation is of S/sqrt(n).Hence, since 1.23/sqrt(5) = 0.55, the sample means would have a mean of 3.3 and a standard deviation of 0.55.

The equation for the axis of symmetry for the given parabolic graph is found as: x = 3.
Explain about the parabolic curve:A parabola is the graph of a quadratic function and features a vertical line passing through its vertex as its axis of symmetry.
A parabola, a U-shaped curve, is the shape of a quadratic function's graph. The graph's vertex, which is an extreme point, is one of its key characteristics. The vertex, or lowest point on the graph or minimal value of the quadratic function, is where the parabola will open up. The vertex is the highest location on the graph or the maximum value if the parabola opens downward. The vertex is a pivotal location on the graph in both scenarios.The graph is also symmetric, with the axis of symmetry being a vertical line that passes through the vertex.
Thus, the equation for the axis of symmetry for the given parabolic graph is found as: x = 3.

the mean age of instructors at widget college is 52.7 years. choose the correct null and alternative hypotheses based on the above claim.
Answer:
The null and alternative hypotheses can be formulated based on the claim about the mean age of instructors at Widget College. Let's define the null and alternative hypotheses:
Step-by-step explanation:
Null Hypothesis (H0): The mean age of instructors at Widget College is equal to 52.7 years.
Alternative Hypothesis (Ha): The mean age of instructors at Widget College is not equal to 52.7 years.
In statistical hypothesis testing, the null hypothesis typically assumes no significant difference or effect, while the alternative hypothesis suggests there is a significant difference or effect. In this case, the claim states a specific value of the mean age (52.7 years), so we can set the null hypothesis as the equality of the mean age to that value. The alternative hypothesis is then formulated as the negation of the null hypothesis, indicating that the mean age is not equal to 52.7 years.

If 33% of a man monthly salary is Birr of 6600, what is his total monthly salary? A. 23,200 B. 20,000 C. 9,850 D. 16,450
Answer:
The correct answer is B. 20,000
Step-by-step explanation:
To determine the man's total monthly salary, we can set up a simple equation using the given information. Let's denote the total monthly salary as "x."
According to the information provided, 33% of the man's monthly salary is equal to Birr 6600. We can express this relationship mathematically as:
0.33x = 6600
To solve for "x," we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 0.33:
x = 6600 / 0.33
Evaluating the right side of the equation gives:
x ≈ 20,000
Therefore, the man's total monthly salary is approximately Birr 20,000.
Hence, the correct answer is B. 20,000.

The board of directors of a corporation must select a president, a secretary, and a treasurer. In how many possible ways can this be accomplished if there are 24 members on the board of directors?
There are about 12,144 possible ways to select a president, a secretary, and a treasurer from a board of directors with 24 members.
The board of directors of a corporation needs to select a president, a secretary, and a treasurer. There are 24 members on the board of directors.
To find the number of possible ways this can be accomplished, we can use the concept of permutations.
First, we need to determine the number of choices for each position.
Since the president position can be filled by any of the 24 members, there are 24 options.
After the president is chosen, there are 23 remaining members who can be chosen for the secretary position.
Finally, for the treasurer position, there are 22 remaining members to choose from.
To find the total number of possible ways to fill all three positions, we can multiply the number of options for each position: 24 * 23 * 22 = 12,144.
Therefore, there are about 12,144 possible ways to select a president, a secretary, and a treasurer from a board of directors with 24 members.

Working together, arjun and maria can oil the lance ina bowling alley in 4.24 hours. had she done it alone it would have taken maria eight hours. how long would it take arjun to do it alone?
Arjun alone will take 9 hours to complete the work.
What is time and work concept?Work can be described as anything with an effect or outcome, which is often the desired or expected one. The fundamental concept of Time and Work is the same as it is in all Arithmetic topics, namely the principle of Proportionality.
Whenever the amount of work done remains constant, efficiency is inversely proportional to time.
Now, according to the question;
Let the total work done be 1 unit.
The work done by both Arjun and Maria in 1 hours = 1/4.24
The work done by Maria alone in 1 hours = 1/8
Thus, the work done by Arjun alone = 1/4.24 - 1/8.
= (8 - 4.24)/33.92
= 3.76/33.92 work in one hour
So, the total time by Arjun to finish the work alone is 33.92/3.76
Thus, the total time by Arjun to finish the work alone is 9 hours.
