A water tank has a density of 1000 kg/m3 and a mass of 100 kg.Calculate the volume of the water tank.l
Answers
\(D=m/V\)
D = densitym = massV = volumeSolutionWe're given:
D = 1000 kg/m³m = 100 kgV = ?Plug these values into the equation and solve for V:
\(D=m/V\\1000=100/V\\V=100/1000\\V = 0.1\)
The volume of the water tanks is 0.1 m³.
Answer:
0.1
Step-by-step explanation:
To calculate the volume of the tank, we will use the formula D = m ÷ V.
Here: D = density, m = mass, and V is the volume.
The formula rearranged for the volume is V = m ÷ d.
Here are the formulae:
\(\boxed{\boxed{\begin{aligned}\sf{d=m\div V}\\\sf{d\times V=m}\\\sf{V=m\div d\end{aligned}}}}\)
Insert the values into the appropriate formula, i.e., V = m ÷ d:
V = 100 ÷ 1000V = 0.1 m³Hence, the volume of the water tank is 0.1 cubic meters

Answers
The linear approximation of sin(9x) at x = 0 is A + Bt, where A = sin(0) = 0 and B = f'(0) = 9 that is sin(9x) ≈ 0 + 9x = 9x
The linear approximation of a function at a point is given by its first-order Taylor polynomial, which can be expressed as f(a) + f'(a)(x-a). In this case, we have a = 0 and f(x) = sin(9x), so we need to find f'(x) and evaluate it at x = 0.
Taking the derivative of sin(9x) with respect to x, we get:
f'(x) = 9cos(9x)
Evaluating this at x = 0, we get:
f'(0) = 9cos(0) = 9
So the linear approximation of sin(9x) at x = 0 is given by:
sin(9x) ≈ 0 + 9x = 9x

Answers
The function $f(x, y) = 11x - 5y$ has a global maximum of $105$ at $(0, 6)$ and a global minimum of $-54$ at $(0, -9)$, the first step is to find the critical points of the function.
The critical points of a function are the points where the gradient of the function is equal to the zero vector. The gradient of the function $f(x, y)$ is: ∇f(x, y) = (11, -5)
```
The gradient of the function is equal to the zero vector at $(0, 6)$ and $(0, -9)$. Therefore, these are the critical points of the function.
The next step is to evaluate the function at the critical points and at the boundary of the region. The boundary of the region is given by the inequalities $y \ge x - 9$, $y \ge -x - 9$, and $y \le 6$.
The function $f(x, y)$ takes on the value $105$ at $(0, 6)$, the value $-54$ at $(0, -9)$, and the value $-5x + 54$ on the boundary of the region.
Therefore, the global maximum of the function is $105$ and it occurs at $(0, 6)$. The global minimum of the function is $-54$ and it occurs at $(0, -9)$.
The first step is to find the critical points of the function. The critical points of a function are the points where the gradient of the function is equal to the zero vector. The gradient of the function $f(x, y)$ is: ∇f(x, y) = (11, -5)

The next step is to evaluate the function at the critical points and at the boundary of the region. The boundary of the region is given by the inequalities $y \ge x - 9$, $y \ge -x - 9$, and $y \le 6$.
We can evaluate the function at each of the critical points and at each of the points on the boundary of the region. The results are shown in the following table:
Point | Value of $f(x, y)$
$(0, 6)$ | $105$$(0, -9)$ | $-54$$(x, x - 9)$ | $11x - 45$ for $x \ge 9$$(x, -x - 9)$ | $-5x + 54$ for $x \ge 9$$(x, 6)$ | $11x - 30$ for $-9 \le x \le 6$The largest value in the table is $105$, which occurs at $(0, 6)$. The smallest value in the table is $-54$, which occurs at $(0, -9)$. Therefore, the global maximum of the function is $105$ and it occurs at $(0, 6)$.

Question 3 Let X1, X2,..., Xn be independent random variables, each having a uniform distri- bution over (0,1). Let M = maximum (X₁, X₂,..., Xn). Show that the distribution function of M, FM(-), is given by FM(x)=x, 0≤x≤1 What is the probability density function of M?
Answers
The distribution function of M, FM(-), is given by FM(x) = x, 0 ≤ x ≤ 1.
The probability density function of M is\(fM(x) = n * x^(^n^-^1^)\), 0 ≤ x ≤ 1.
In order to understand the distribution function of M, we need to consider the probability that M is less than or equal to a given value x. Since each Xi is uniformly distributed over (0,1), the probability that Xi is less than or equal to x is x.
For M to be less than or equal to x, all of the random variables Xi must be less than or equal to x. Since these variables are independent, their joint probability is the product of their individual probabilities. Therefore, the probability that M is less than or equal to x can be expressed as the product of n x's: P(M ≤ x) = x * x * ... * x = \(x^n\).
The distribution function FM(x) is defined as the probability that M is less than or equal to x. Therefore, FM(x) = P(M ≤ x) = \(x^n\).
To find the probability density function (PDF) of M, we differentiate the distribution function FM(x) with respect to x. Taking the derivative of \(x^n\)with respect to x gives us \(n * x^(^n^-^1^)\). Since the range of M is (0,1), the PDF is defined only within this range.
The distribution function of M is FM(x) = x, 0 ≤ x ≤ 1, and the probability density function of M is \(fM(x) = n * x^(^n^-^1^)\), 0 ≤ x ≤ 1.

Answers
A university surveys its student-athletes about their experience in college sports. The survey only includes student-athletes with scholarships. This is an example of sampling bias.
In the field of statistics, sampling bias is a type of bias in which a sample is collected in such a way that some members of the intended population have a lower or higher sampling probability than others. It results in a biased sample of the population where all individuals, or instances, were not equally likely to have been selected. If this is not corrected, results can be erroneously attributed to the phenomenon under study rather than to the method of sampling. Here as the sample of the survey only includes the student athletes with scholarship, it becomes biased.

Answers
a) Amplitude: 2
b) Period: 2π
c) Phase Shift: 0
d) Vertical Translation: None
e) Graph: y = -2cos(x)
Function: y = -2cos(x)
a) Amplitude:
The amplitude of a cosine function is the absolute value of the coefficient of the cosine term. In this case, the coefficient is -2. Therefore, the amplitude is 2.
b) Period:
The period of a cosine function is given by 2π divided by the coefficient of the x term. In this case, there is no coefficient of the x term, which implies that the period is the default period of a cosine function, which is 2π.
c) Phase Shift:
The phase shift determines the horizontal shift of the graph. In this case, there is no additional horizontal shift, so the phase shift is 0.
d) Vertical Translation:
The vertical translation determines the vertical shift of the graph. In this case, there is no additional vertical translation, so the function remains centered on the x-axis.
e) Graph:
The graph of the function y = -2cos(x) is a cosine function with an amplitude of 2, a period of 2π, no phase shift, and no vertical translation. It oscillates above and below the x-axis symmetrically.

Answers
The correct statement is: "Designed experiments usually proceed sequentially - first with a lot of screening variables, then with a magnifying glass on a few important ones."
In the design of experiments, it is common to start with a screening phase where a large number of variables are tested to identify the most influential ones. This initial phase helps to narrow down the focus and identify the key factors that have a significant impact on the response variable. Once the important variables are identified, a more detailed and focused experiment can be conducted to study those variables in greater depth.
The other options are incorrect:
"We can use the same level of replications and detail on all variables at the same time with a fractional factorial design for all levels of experimentation, large and small" is incorrect. Fractional factorial designs are typically used when there are many factors to be studied, and it is not feasible to test all possible combinations. They involve selecting a subset of the factors to be studied at different levels, which allows for a more efficient use of resources. It does not imply using the same level of replications and detail on all variables simultaneously.
"Only when there is no retrospective data to be had" is incorrect. Retrospective data refers to existing data that has been collected in the past. The decision to use designed experiments is not dependent on the availability of retrospective data. Designed experiments are valuable even when retrospective data exists as they provide a controlled and systematic approach to study the factors and their effects.
"None of these" is also incorrect as the first statement mentioned is the correct one.

a watermelon breeder has two garden plots with different varieties of watermelons. in garden plot 1, the mean fruit weight is 25 lbs and the narrow-sense heritability is estimated at 12%. in garden plot 2, the mean fruit weight is 20 lbs, and the narrow-sense heritability is estimated at 88%. in which garden plot do you expect that the environment is playing a larger role in the inheritance of fruit mass?
Answers
In garden plot 1 we can expect that the environment is playing a larger role in the inheritance of fruit mass.
Based on the information provided, it seems that the environment is playing a larger role in the inheritance of fruit mass in garden plot 1 since the narrow-sense heritability (a measure of the proportion of variation in a trait that is due to genetic factors) is lower in this plot compared to garden plot 2. This suggests that the fruit mass of watermelons in garden plot 1 is more influenced by environmental factors such as temperature, soil quality, and other conditions. In contrast, the higher narrow-sense heritability in garden plot 2 suggests that the fruit mass of watermelons in this plot is more influenced by genetic factors.
It is important to note that narrow-sense heritability only measures the proportion of variation in a trait that is due to genetic factors and does not take into account the influence of environmental factors. Therefore, the environment can still play a significant role in the inheritance of fruit mass in both garden plots, even if the narrow-sense heritability is higher in one plot compared to the other.

Step-by-step explanation:
evaluate the following expression given the function below when f(-2) f(x)=x²+7
Answers
we are given the following function:
\(f(x)=x^2+7\)We are asked to find:
\(f(-2)\)This means the value of the function when x = -2, therefore, in the function where ever we find "x" we replace it with -2, like this:
\(f(-2)=(-2)^2+7\)Solving the operations:
\(f(-2)=4+7=11\)Therefore, f(-2) = 11

Identify the correct explanation for why △ABC
and △DEC
are similar, and find EC
.
The figure shows two triangles A B C and D E C with common vertex C. Sides A B and E D are parallel. The length of segment A C is 18 units. The length of segment B C is 24 units. The length of segment D C is 24 units.
What is ec's value and how can I know?
Answers
Answer:
△ABC and △DEC are similar because they both have the same angle at vertex C, and corresponding sides are proportional. To find EC, we use the similarity ratio of the two triangles, which is equal to the ratio of the lengths of corresponding sides. In this case, the ratio of AC to EC is 18/24, so EC = (24 x 18)/24 = 18 units.
C
As show.
Because AB//ED, so <B=<e, <A=<D
and <ABC=<ECB {to triangle with tree equal angles are alike}
and AC/CD=BC/EC
so 18/24=24/EC EC=24 times 24/18=32
2) what is the perimeter of the kite shown above? (Hint: there are 4 right angle triangles here
Answers
You have to use the Pythagorean theorem to find the missing side length
So it would be 10 squared plus 12 squared equals 15.62
Then you double it because of the two top side lengths
Then you use the Pythagorean theorem for the bottom
12 squared plus 30 squared which equals 32.31
And you double that as well
31.24 plus 64.62 equals 95.86 and you just round to 95.8
