The unit rate in minutes per meter is 28.8 minutes per meter when David fills an aquarium to a depth of 3/8 meters in 3 3/5 minutes
The given Depth of the aquarium = 3/8 meters
Time taken to fill the aquarium = 3 3/5 minutes
To find the the unit rate in minutes per meter, we need to divide the time taken to fill the aquarium by the depth of the aquarium
So, Unit rate in minutes per meter = 3 3/5minutes ÷ 3/8 meters
= 18/5 ÷ 3/8
= 18/5 ×8/3
= 144/15
= 28.8 minutes per meter
Hence, the unit rate in minutes per meter is 28.8 minutes per meter when David fills an aquarium to a depth of 3/8 meters in 3 3/5 minutes
The correct question is David fills an aquarium to a depth of 3/8 meters in 3 3/5 minutes. What is the unit rate in minutes per meter?

Based on the knowledge of trigonometric expressions and properties of trigonometric functions, the value of the sine function is equal to - √731 / 30.
How to find the value of a trigonometric functionHerein we must make use of trigonometric expressions and properties of trigonometric functions to find the right value. According to trigonometry, both cosine and sine are negative in the third quadrant. Thus, by using the fundamental trigonometric expression (sin² α + cos² α = 1) and substituting all known terms we find that:
\(\sin \theta = -\sqrt{1 - \cos^{2}\theta}\)
\(\sin \theta = - \sqrt{1 - \left(-\frac{13}{30} \right)^{2}}\)
sin θ ≈ - √731 / 30

For the function f(x) = 2/x, the difference quotient is D: -2 / x(x + h).
What is a function?
In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.
The difference quotient for a function f(x) is given by -
(f(x + h) - f(x)) / h
Substituting f(x) = 2/x, we get -
(f(x + h) - f(x)) / h = [2 / (x + h) - 2 / x] / h
To simplify this expression, we need to find a common denominator -
2x / x(x + h) - 2(x + h) / x(x + h) = [2x - 2(x + h)] / x(x + h)
= -2h / x(x + h)
Multiplying both numerator and denominator by -1, we get -
(2h) / x(x + h) × (-1)
= -2h / x(x + h)
Therefore, the solution obtained is -2 / x(x + h).

Farmer Ed has 3,000 meters of fencing and wants to enclose a rectangular plot that borders on a river.The largest area that can be enclosed is 750,000 square meters.
What is the largest area that can be enclosed?To get the largest area that can be enclosed, we have to find the dimensions of the rectangular plot. Let's assume that the width of the rectangle is x meters.The length of the rectangle can be found by subtracting the width from the total length of fencing available:L = 3000 - x. The area of the rectangle can be found by multiplying the length and width:Area = L × W = (3000 - x) × x = 3000x - x²To find the maximum value of the area, we can differentiate the area equation with respect to x and set it equal to zero.
Then we can solve for x: dA/dx = 3000 - 2x = 0x = 1500. This means that the width of the rectangle is 1500 meters and the length is 3000 - 1500 = 1500 meters.The area of the rectangle is therefore: Area = L × W = (3000 - 1500) × 1500 = 750,000 square meters. So the largest area that can be enclosed is 750,000 square meters.

If the correlation coefficient is positive, then above-average values of one variable are associated with above-average values of the other.
a) true
b) false
The correct answer is A, true. When the correlation coefficient is positive, it indicates that there is a positive relationship between two variables.
This means that as one variable increases, the other variable also tends to increase. Therefore, above-average values of one variable are associated with above-average values of the other. However, it is important to note that a positive correlation does not necessarily mean that there is a strong relationship between the two variables or that one variable causes the other. It simply means that there is a tendency for the two variables to vary in the same direction.
In statistical analysis, understanding the correlation coefficient and the relationship between variables can help to make better decisions and predictions.

the brain volumes () of 50 brains vary from a low of to a high of . use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of , assuming the estimate is accurate if it is within 15
The estimated standard deviation from the range rule is 145.5 cm3.As it is 29.8 cm3 smaller than the exact standard deviation, we consider that the estimation is not accurate enough.
Generally, brain volumes which are smaller than 921.1 cm3 can be considered significantly low and bigger than 1417.5 cm3 can be considered significantly high. Hence, brain volume of 1457.5 cm3 is bigger than the expected maximum, so it can be considered significantly high.
The calculation goes like this,
According to the range rule, the standard deviation and range, or the distance between the maximum and smallest value, are roughly inversely proportional:
\(s=R/4\)
If we have a sample of 50 brains volumes, and they range from 910 cm3 to 1492 cm3, we can estimate the standard deviation as:
\(s=max-min/4\)
s=1492-910/4=582/4=145.5
The exact standard deviation is 175.3 cm3.The difference is 175.3-145.5=29.8 cm3, so the estimation is not accurate enough.
The range rule of thumb states that we should anticipate a maximum value that is approximately two standard deviations above the mean and a lowest value that is approximately two standard deviations below the mean. The expected ranges are as follows given our mean volume of 1169.3 cm3 and standard deviation of 124.1 cm3:
Min= M-2s=1169.3-2*124.1=921.1
Max=M+2s=1169.3+2*124.1=1417.5
The brain capacity of 1457.5 cm3 can be regarded as significantly high because it is higher than the predicted maximum.

The probability that a marksman will hit a target each time he shoots is 0. 89. If he fires 15 times, what is the probability that he hits the target at most 13 times?.
The probability that marksman will hits the target at most 13 times is 27.92%.
Explain the term binomial distribution?Let X be the quantity of times that target is hit and be a random variable. 15 rounds are fired, hence the number of trials ("n") is equal to 10 as a result. In a binomial distribution, "p" denotes the likelihood of success, and "q" is the likelihood of failure (where q = 1 - p). Since there is a 0.89 chance of striking the target, p = 0.89 and q = 0.11.The number of successes ("x") is the probability mass function for such binomial distribution.
P(X = x) = ⁿCₓ . pˣ . qⁿ⁻ˣ
We are interested in the likelihood that the target will be struck exactly five times, therefore the desired number of successes is five (i.e., x = 13).
P(X = 13) = ¹⁵C₁₃. (0.89)¹³ (0.11)²
P(X = 13) = 0.2792
P(X = 13) = 27.92%

A study of freely forming groups in bars throughout Europe examined the number of individuals found in groups who were laughing together. Let X be the number of individuals in laughing groups. Here is the probability distribution for X:
Number of individuals X 2 3 4 5 6
Probability 0. 51 0. 34 0. 10 0. 04 0. 01
(a) Find P(3
(b) Find the mean μ of X.
(c) Find the standard deviation σ of X
(a) To find P(3), we look at the probability distribution table and find the probability associated with X = 3. From the given information, P(X = 3) = 0.34.
(b) To find the mean μ of X, we multiply each value of X by its corresponding probability and sum the results.
μ = (2 * 0.51) + (3 * 0.34) + (4 * 0.10) + (5 * 0.04) + (6 * 0.01)
= 1.02 + 1.02 + 0.40 + 0.20 + 0.06
= 2.70
Therefore, the mean μ of X is 2.70.
(c) To find the standard deviation σ of X, we first calculate the variance. The variance is the sum of the squared differences between each value of X and the mean, weighted by their respective probabilities.
Var(X) = [(2 - 2.70)^2 * 0.51] + [(3 - 2.70)^2 * 0.34] + [(4 - 2.70)^2 * 0.10] + [(5 - 2.70)^2 * 0.04] + [(6 - 2.70)^2 * 0.01]
= 0.1764 + 0.0289 + 0.0324 + 0.0276 + 0.0144
= 0.2797
The standard deviation σ of X is the square root of the variance.
σ = √Var(X) = √0.2797 ≈ 0.5288
Therefore, the standard deviation σ of X is approximately 0.5288.
