Answers
The height of water in the tank in feet after t seconds can be expressed as h(t) = H - (Aw/Ah) 2gh t2, where Aw and Ah are the cross-sectional areas of the water and the hole in square feet respectively,
and g is the gravitational acceleration (32 ft/s2). The interval of definition for h(t) is 0 ≤ t ≤ H/2gh.
The graph of h(t) is a parabola with its vertex at (H/2gh, H) and is symmetric about the line t = H/2gh. It starts at (0, H) and gradually decreases to (H/2gh, 0).
Given the tank is 11 ft high, has radius 2 ft and the circular hole has radius in, and it is initially full, the time it will take to empty can be calculated as: t = √(2H/gAh) = √(22/(32 x π(0.52))) = 3.87 seconds. Therefore, it will take approximately 3.87 seconds to empty.

question 9 in r, which statistical measure demonstrates how strong the relationship is between two variables?
Answers
Correlation analysis is a statistical technique used to measure the strength of the relationship between two variables.
Correlation analysis in research is a factual strategy used to quantify the strength of the direct correlation between two factors and figure out their affiliation. It ascertains the degree of progress in one variable because of the change in the other. A high correlation focuses on a solid correlation between the two factors, while a low correlation implies that the factors are pitifully related.
With regard to statistical surveying, specialists use this strategy to break down quantitative information gathered through research strategies like reviews and live surveys. They attempt to recognize the correlation, designs, huge associations, and patterns between two factors or datasets.
There is a positive correlation between two variables when an increment in one variable prompts an increment in the other. Then again, a negative correlation implies that when one variable expands, different declines as well as the other way around.
Correlation analysis is used to study practical cases. Here, the researcher can't manipulate individual variables. For example, correlation analysis is used to measure the correlation between the patient's blood pressure and the medication used.
Marketers use it to measure the effectiveness of advertising. Researchers measure the increase/decrease in sales due to a specific marketing campaign.
Thus, Correlation analysis is a statistical technique used to measure the strength of the relationship between two variables.

Step-by-step explanation:
Answer:
\(\frac{5y}{16}\)
Step-by-step explanation:
Given
\(\frac{5y}{8}\) - \(\frac{5y}{16}\)
To subtract the fractions we require them to have a common denominator.
Multiply numerator/ denominator of \(\frac{5y}{8}\) by 2
= \(\frac{5y(2)}{8(2)}\) - \(\frac{5y}{16}\)
= \(\frac{10y}{16}\) - \(\frac{5y}{16}\)
Now subtract the numerators, leaving the denominator
= \(\frac{10y-5y}{16}\)
= \(\frac{5y}{16}\)

EXPLANATION
Given the system of equations:
(1) 3x + 5y = -17
(2) 2x + 4y = 6
Multiplying (1) by 2 and (2) by 3:
(1) 6x + 10y = -34
(2) 6x + 12y = 18
Subtracting (2) to (1):
(2) 6x + 12y = 18
-
(1) 6x + 10y = -34

16^-k -1= (1/64)^-k this is for solving for exponential functions in Algebra 2.
Answers
The value of k is -2/5. This is the value of K if \(16^{-k-1} = (\frac{1}{64})^{-k}\). Exponents are used in exponential functions, as the name suggests.
A constant serves as the exponent in an exponential function, but not the other way around (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).
\(16^{-k-1} = (\frac{1}{64})^{-k}\)
\((4^{2})^{-k-1} = (\frac{1}{4^{3} })^{-k}\)
\(4^{-2k-2} = (4^{-3})^{-k}\)
\(4^{-2k-2} = 4^{3k}\)
As the base are equal so the exponents are equal
Hence,
-2k-2 = 3k
-2 = 3k + 2k
-2 = 5k
-2/5 =k
Therefore the value of K is -2/5

when the entire 95% confidence interval is less than 1, the odds ratio is statistically significant.
Answers
The "correct" statement is that the odds ratio appears statistically significant when the whole 95% confidence interval is much less than 1.
Explain the meaning of the term confidence interval?In statistics, a confidence interval describes the likelihood that a population parameter would fall between a set of values a predetermined percentage of the time.
Confidence ranges that include 95% or 99% of anticipated observations are frequently used by analysts. Therefore, it can be concluded that there is a 95% probability that the true value falls within that range if a point estimate of 10.00 with just a 95% confidence interval = 9.50 - 10.50 is derived using a statistical model. Point estimates lack the information that confidence intervals do. The researchers reach at an upper as well as lower bound that 95% of the time contain the true mean by creating a 95% confidence interval to use the sample's mean plus standard deviation and presuming a normal distribution represented by the bell curve.Thus, the "correct" statement is that the odds ratio appears statistically significant when the whole 95% confidence interval is much less than 1.

According to the area of rectangle, the maximum area is given by a 300 × 500 ft rectangle that is being half of a square
The formula to calculate the area of square is written as

Here we have know that if there were no river then the maximum area would be given by a square configuration since increasing the length and decreasing the width of a square by the same value t will decrease the area by a square with sides of length t.
Here we have to add the river on one side.
As we all know that we need to fence in a rectangle on one side of the river and then here we have imagine an identical rectangle on the other side of the river.

Find the distance between the points (4,9) and (10,9).
Answers
Answer:
The distance between (4,9) and (10,9) is 6
Step-by-step explanation:
You need to follow this formula!
√x2 - x1^2 + y2 - y1^2
Your first point (4,9) is point 1
The other (10,9) is labeled as point 2
Take the 10 and subtract it from 4 to find the x coordinate.
10-4 = 6
Then you square it
36
Take the 9 and subtract it from the other 9.
0
So far we have √36
Simplify!
=6
Therefore, the distance between (4,9) and (10,9) is 6
The formula for the distance between point (x_1,y_1) and (x_2,y_2) is,
\(\text{d}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)
Determine the distance between points (4,9) and (10,9) by using distance formula.
\(\text{d}=\sqrt{(10-4)^2+(9-9)^2}\)
\(=\sqrt{36+0}\)
\(=\sqrt{36}\)
\(=6\)
So distance between the two points is 6.

The conveyor belts can move the 200 pounds of recyclable aluminum from the delivery truck to a storage area in minutes
Answers
It takes approximately 1.2 minutes to move the cans to the storage area when both conveyor belts are used.
We can begin the problem by using the formula:
work = rate x time
Let's denote the rate of the first belt as R1 and the rate of the second belt as R2. Then, we can write:
R1 = 200 pounds / 2 minutes = 100 pounds per minute
R2 = 200 pounds / 3 minutes ≈ 66.67 pounds per minute
When both belts are used, they work together to move the same 200 pounds of cans. Therefore, we can add their rates to get the total rate:
R = R1 + R2 = 100 + 66.67 = 166.67 pounds per minute
To find the time it takes to move the cans to the storage area, we can rearrange the formula:
time = work / rate
The total work is 200 pounds, so we have:
time = 200 pounds / 166.67 pounds per minute ≈ 1.2 minutes

g (b) show that among a group of 621 people, there are at least 21 who are born on the same day of the month (e.g., the 21st or the 12th, etc.). is the same fact true if there are only 620 people?
Answers
There would be 20 more of us (620-600). There would have been a day when more than 20 people would have been born.
A counting-based argument is known as a combinatorial argument or combinatorial proof. This line of reasoning has already been used, for instance in the section on Stirling numbers of the second sort.
It is mentioned that 620 persons shared the same month of birth. Assume that there were 30 days in the month to avoid losing generality. We'll demonstrate that through contradiction, assuming there were no more than 20 births on any one day throughout that month.
(Beyond that, we have the outcome.)
Now within Thirty Days, 30 * 20 births made up the total. However, since the population was 621 strong, another 21 persons had to be born on a day within that month. Note that the pigeon-hole principle was used in this instance. As a result, someday x, more than twenty people will be born. Consequently, there are at least 21 people who share a birthday.
The outcome would be the same whether there were 620 people. The discussion we had led to this. Keep in mind that in this scenario, we would have 20 more people (620-600). Therefore, a day when more than 20 people were born would have come.
