The value that is used to estimate the value of the population parameter is the sample statistic. Hence, option (c) is the correct answer.

A sample statistic is a piece of statistical information that is obtained from a fraction of the population. Just as its name suggests, it is computed from our sample data to help provide us insight into the population parameters.

A sample is a fraction of a given population. Once one has a sample, one can calculate various statistics about the sample, like median, average, or deviation. This can help one draw inferences about large populations using small samples.

A sample statistic is a random variable. Thus, it has an associated probability distribution, called the sampling distribution. The nature of the sampling distribution is essential in determining the properties of the sample statistic.

Hi there! In order to determine if A and B are inverses of each other, we need to check if \(AB = BA = I\), where I represents the identity matrix. From the given equation,\((A+B)^2 = A^2 + 2AB + B^2\), we can expand it as:
\((A+B)(A+B) = A^2 + 2AB + B^2\)

Let's break it down step by step.
Expanding further, we get:
\(A^2 + AB + BA + B^2 = A^2 + 2AB + B^2\)
Now, let's simplify the equation:
\(AB + BA = AB + BA\)
Since the equation holds true, we can say that \(AB = BA\). However, this does not necessarily mean that A and B are inverses of each other.

Inverse matrices have the property that.

\(AB = BA = I,\) but the given equation only shows that\(AB = BA.\) To determine if A and B are inverses of each other, you need to check if

\(AB = BA = I.\) If they satisfy this condition, then A and B are inverses. Otherwise, they are not inverses.

Step-by-step explanation:

these are tough to solve  , don't feel bad.   soo part of the trick is that the two side set  up similar triangles, then  

16 / y  = y /9     ( the two triangles

16* 9 = \(y^{2}\)

The equation 0.05n + 0.10d = 3.65 is equivalent to the equation 0.05n + 0.1d + 3.65. This equation states that the total value of the nickles and dimes in Jada's coin jar is 3.65.

The equivalent equation  0.05n + 0.1d+3.65 is 5n + 10d = 365. This equation can be obtained by multiplying both sides of the original equation by 100 to eliminate the decimal points. This gives us:

100(0.05n + 0.1d + 3.65) = 100(3.65)
5n + 10d + 365 = 365

Next, we can subtract 365 from both sides of the equation to isolate the variables on one side:

5n + 10d = 365

Therefore, the equation 5n + 10d = 365 is equivalent to the original equation 0.05n + 0.1d+3.65 and can be used to represent the situation of Jada's coin jar.

The answer to this involves the relation between time, speed, and distance, as well as a couple of conversion factors.

_____

Using the above conversion factors with Jordan's time and speed, we can find the distance Jordan traveled to be ...

  distance = speed × time

  distance = (16 km/h) × (40 min) = (16×1000 m)/(60 min) × (40 min)

  distance = 32000/3 m = 10,666 2/3 m

Using Sarah's time and speed, we find Sarah's distance to be ...

  distance = (3 8/9 m/s) × (40 min) × (60 s)/(1 min) = (3 8/9)(2400) m

  distance = 9333 1/3 m

__

The difference between Jordan's distance and Sarah's is ...

  10,666 2/3 m -9,333 1/3 m = 1,333 1/3 m

Jordan cycled 1,333 1/3 meters farther than Sarah, about 1.33 km.

__

The two went in opposite directions, so their separation is the sum of the distances they traveled.

  10,666 2/3 m +9,333 1/3 m = 20,000 m = 20 km

The two cyclists were 20 km apart at the end of 40 minutes.

The general solution of the given differential equation expressed explicitly as a function of the independent variable, is:

w(x) = (1/16) * \(((3x + 2)^2 + 4Cx - 4x^2)^2\)

To obtain the solution, we can rewrite the given differential equation by separating the variables and integrating. First, we can divide both sides by √w and rearrange the terms:

√w dw = (3x + 2)/\(x^2\) dx

Then, with regard to the relevant variables, we integrate both sides. The integral of √w with respect to w can be computed using the power rule, while the integral of (3x + 2)/\(x^{2}\) with respect to x can be found using partial fractions. After integrating and simplifying, we obtain the general solution as:

w(x) = (1/16) * \(((3x + 2)^2 + 4Cx - 4x^2)^2\)

Here, C is the arbitrary constant that can take any real value.

This general solution represents a family of functions that satisfy the given differential equation. By choosing different values for the constant C, we can obtain specific solutions corresponding to different initial conditions or constraints imposed on the problem.

Answer:

x = 8 units.

Step-by-step explanation:

We'll begin by calculating the length of the two squares attached to the triangle.

From the question given above, the areas of the two square are the same i.e 32 units². Therefore, the length of the two square will be the same.

Now, we shall determine the length of the square as follow:

Area of square (A) = 32 units²

Length (L) =?

Area of square (A) = Length (L) × Length (L)

A = L × L

A = L²

32 = L²

Take the square root of both side

L = √32 units

Therefore, the length of the square is √32 units. This implies that the length of both side of the triangle is √32 units

Now, we shall determine the value of x using pythagoras theory.

From the diagram above we can see that x is the Hypothenus i.e the longest side. Thus, the value of x can be obtained as follow:

x² = (√32)² + (√32)²

x² = 32 + 32

x² = 64

Take the square root of both side

x = √64

x = 8 units.

Therefore, the value of x is 8 units.

TRUE. As one performs multiple separate hypothesis tests, the risk of committing a Type I error (rejecting a true null hypothesis) accumulates.

This overall risk is referred to as the experiment-wise alpha level or family-wise error rate (FWER). It represents the probability of making at least one Type I error among all the conducted tests.

When multiple hypothesis tests are performed simultaneously or sequentially, the individual alpha levels (typically set at 0.05) for each test may no longer be appropriate. This is because if we conduct, for example, 20 separate tests with an alpha level of 0.05 for each test, the cumulative chance of committing at least one Type I error can be much higher than the desired 5%.

To control the experiment-wise error rate, various multiple comparison procedures and adjustments can be employed, such as the Bonferroni correction or the Holm-Bonferroni method. These methods aim to maintain a desired level of significance for the entire set of tests, reducing the risk of accumulating Type I errors.

The equation of the quadratic function is: f(x) = 3x² - 18x - 48

To find the equation of a quadratic function in standard form, we need to use the zeros of the function and one additional point.

Given that the zeros are x = 8 and x = -2, we can write the equation in factored form as:

f(x) = a(x - 8)(x + 2)

To find the value of "a," we can use the fact that f(2) = -72.

Substituting x = 2 into the equation, we have:

-72 = a(2 - 8)(2 + 2)

Simplifying, we get:

-72 = a(-6)(4)

-72 = -24a

Dividing both sides by -24, we find:

3 = a

Now that we know the value of "a," we can rewrite the equation in standard form:

f(x) = 3(x - 8)(x + 2)

The marginal profit if you sell 150 pieces of pie is $1.20 per piece.E. The marginal profit if you sell 150 pieces of pie is the additional profit made by selling one more unit of a good.

Given,The cost to make x servings of apple pie is C(x) = 300+ 0.1x +0.003x².

The price to sell one piece of pie is $4.00.So, the revenue function, R(x) can be written asR(x) = price per unit × number of units soldR(x) = 4x.

The profit function, P(x) is given by the difference between the revenue function and cost function i.e.,P(x) = R(x) - C(x)

Substituting R(x) = 4x and C(x) = 300 + 0.1x + 0.003x² in P(x), we haveP(x) = 4x - (300 + 0.1x + 0.003x²)

P(x) = 4x - 300 - 0.1x - 0.003x²

P(x) = - 0.003x² + 3.9x - 300.

The marginal profit function is given by P'(x) = R'(x) - C'(x).Let's find R'(x) and C'(x).Differentiating R(x) = 4x with respect to x, we getR'(x) = 4Differentiating C(x) = 300 + 0.1x + 0.003x² with respect to x, we getC'(x) = 0.1 + 0.006x.

Substituting R'(x) = 4 and C'(x) = 0.1 + 0.006x in P'(x), we getP'(x) = 4 - (0.1 + 0.006x)P'(x) = 3.9 - 0.006x.

Now, let's find the marginal profit if we sell 150 pieces of pie.

Substituting x = 150 in P'(x), we getP'(150) = 3.9 - 0.006 × 150P'(150) = $1.20 per piece.

The marginal profit if we sell 150 pieces of pie is $1.20 per piece.

The marginal profit is the additional profit made by selling one more unit of a good.So, if we sell one more piece of pie, the profit will increase by $1.20.
