To find the critical value for a two-tail test with a sample standard deviation, an n-value of 36, and an alpha of 0.05, you will need to use the t-distribution table (as the population standard deviation is not given). However, since you have only provided the sample standard deviation and not its actual value, I cannot calculate the specific critical value for you.

Here are the general steps to find the critical value:
1. Calculate the degrees of freedom: df = n - 1 = 36 - 1 = 35
2. Divide the alpha (0.05) by 2 for a two-tail test, resulting in 0.025 in each tail.
3. Look up the t-value corresponding to the degrees of freedom (35) and the given alpha level (0.025) in the t-distribution table.
4. The t-value you find in the table is your critical value.

To calculate the receivable days, divide the trade receivables (RM63,000) by the average daily sales (RM1,400) to get approximately 45 days.



To calculate the receivable days, we need to determine the average daily sales and then divide the trade receivables by that figure.

First, we calculate the average daily sales by dividing the total sales by the number of days in the year:

Average daily sales = Total sales / Number of days

Since the year ended on 30th June 2019, there are 365 days in total.

Average daily sales = RM511,000 / 365 = RM1,400

Next, we divide the trade receivables by the average daily sales to find the receivable days:

Receivable days = Trade receivables / Average daily sales

Receivable days = RM63,000 / RM1,400 ≈ 45 days

Therefore, Alice's receivable days on 30th June 2019 is approximately 45 days.

The correct model that represents the money in Anna's savings account (y) after x months, given that she adds $30 every month, is option d) y = 30x.

In this model, the variable x represents the number of months, and the variable y represents the amount of money in Anna's savings account. The equation y = 30x indicates that for each month (x), Anna adds $30 to her savings.

This linear equation represents a direct relationship between the number of months and the total savings accumulated. For example, after 1 month, Anna will have $30 in her account (30 × 1). After 2 months, she will have $60 (30 × 2), and so on.

Option d) is the most appropriate choice because it reflects Anna's consistent monthly deposit of $30 and provides a simple and straightforward representation of her savings growth over time.

The clock starts on the age of volcanic rock basalt at the time the lava solidifies into a rock.

When magma rises to the Earth's surface and erupts as lava, it is exposed to the cooler temperature of the environment. As the lava cools, it solidifies and forms the volcanic rock basalt. This solidification process is when the clock starts on the age of the rock. Basalt is an igneous rock that forms from the cooling and solidification of lava. It is typically dark in color and can have a fine-grained or glassy texture. The solidification of basalt occurs relatively quickly, as lava cools and hardens rapidly upon reaching the Earth's surface.

The clock on the age of basalt starts ticking at the moment it solidifies because from that point onwards, the rock is no longer undergoing any significant changes. By studying the minerals and isotopes present in basalt, scientists can determine its age through radiometric dating techniques. It's important to note that the age of the crust melting or the time the melted rock made it to Earth's surface as lava are not directly related to the age of the volcanic rock basalt. The age of the basalt refers specifically to the time when it solidified from lava.
In summary, the clock starts on the age of volcanic rock basalt at the time the lava solidifies into a rock. This is when the rock is considered to have formed, and from there, scientists can determine its age using various dating methods.

Step-by-step explanation:

The rate by distance from the second base decreasing when he is halfway to the first base is -53.7 ft/s.

The rate by distance from the third base increased at the same moment  53.7 ft/s

Let x be the distance between the runner and the first base.

Let s be the hypotenuse of a right triangle or the distance from the second base to the runner.

1)

s2 = x2 + 902

Taking the derivative of both sides of the equation:

2ss' = 2xx' + 0

s' = xx'/s

When x = halfway, 45 ft, s  = √(452 + 902) = = √(452(1+22)) =45√5

x' is negative because the difference is decreasing between the runner and first base.

s' = 45(-24)/(45√5) = -24√5  ft/s = -53.7 ft/s

2) Assume that z is the runner's distance from the third base. It's a right angle at home.

Since x is taken from the home to the runner and the velocity is positive due to the increasing distance between the two, z' differs from the answer for part 1 in this regard.

z' = 24√5 ft/s = 53.7 ft/s

Matrix-vector multiplication is a linear operation because it satisfies the properties of scalar multiplication and vector addition, which are a(u+v) = au + av and a(cu) = cau, where a is a scalar and u and v are vectors.

Matrix-vector multiplication is a fundamental operation in linear algebra, where a matrix is multiplied by a vector to produce another vector. This operation is considered linear because it adheres to certain properties.

The first property is scalar multiplication, which states that multiplying a vector u by a scalar a and adding it to another vector v (a(u+v)) is equivalent to multiplying u by a (au) and v by a (av) separately and then adding the results (au + av). In other words, the operation distributes over vector addition.

The second property is the distributive property of scalar multiplication, which states that multiplying a vector u by a scalar c and then multiplying the resulting vector (cu) by another scalar a is equivalent to multiplying u by the product of the two scalars (cau). This property allows the scalar multiplication to be distributed over scalar multiplication.

These properties ensure that matrix-vector multiplication preserves the linearity of the underlying vector space. They enable the manipulation and analysis of systems of linear equations, transformations, and other mathematical operations involving matrices and vectors.

Definition of asymptote

a straight line associated with a curve such that as a point moves along an infinite branch of the curve the distance from the point to the line approaches zero and the slope of the curve at the point approaches the

slope of the line

\(f(x)=\sqrt{4x^2+9x}-\sqrt{4x^2+x} \\\\f(x)=2x(1+\frac{9}{4x}) ^{\frac{1}{2} } -2x(1+\frac{1}{4x})^\frac{1}{2}\)

\(f(x)=2x( 1+\frac{1}{2} .\frac{9}{4x} +...... -1 -\frac{1}{2} .\frac{1}{4x} - ......)\)

To evaluate the double integral ∫∫R x³\(e^{(x^2y)}\) dA, where R = {(x, y) | 0 ≤ x ≤ 1, 0 ≤ y ≤ 1}, we can integrate with respect to x and y using the limits defined by the region R.

Let's first integrate with respect to x:

∫(0 to 1) x³\(e^{(x^2y)}\)dx

To evaluate this integral, we can use a substitution. Let u = x²y, then du = 2xy dx. Rearranging, we have dx = du / (2xy).

Substituting these values, the integral becomes:

∫(0 to 1) (1/2y) \(e^u\) du

Now, we integrate with respect to u:

(1/2y) ∫(0 to 1) \(e^u\) du

The integral of \(e^u\) is simply \(e^u\). Evaluating the integral, we get:

(1/2y) [\(e^u\)] from 0 to 1

(1/2y) [\(e^{(x^2y)}\)] from 0 to 1

Now, we substitute the limits:

(1/2y) [(\(e^{y}\)) -( \(e^{0}\))]

(1/2y) [\(e^{y}\) - 1]

Finally, we integrate with respect to y:

∫(0 to 1) (1/2y) [\(e^{y}\)- 1] dy

Evaluating this integral will yield the final result.

The probability of getting a head or a tail when flipping a coin is 1/2.  

Therefore, the probability of getting two heads when tossing two coins is 1/2 x 1/2 = 1/4.

The probability of getting three heads when tossing three coins is 1/2 x 1/2 x 1/2 = 1/8.

Since each person is tossing three coins, the probability that they both obtain the same number of heads is 1/8.

The probability of getting n heads when tossing n coins is 1/2^n. Therefore, the probability of getting the same number of heads when two people toss n coins is 1/2^n. This means that if two people each toss a coin, the probability that they both get heads is 1/4; if they each toss two coins, the probability that they both get two heads is 1/16; if they each toss three coins, the probability that they both get three heads is 1/64; and so on.

We can use the Pythagorean theorem to find the diagonal distance across the rug. According to the theorem, the sum of the squares of the two shorter sides of a right triangle is equal to the square of the longest side (the hypotenuse).

In this case, the length and width of the rug form the two shorter sides of a right triangle, and the diagonal distance is the hypotenuse. So we can use the formula:

diagonal^2 = length^2 + width^2

Plugging in the values given in the problem, we get:

diagonal^2 = 8^2 + 5^2

diagonal^2 = 64 + 25

diagonal^2 = 89

To solve for the diagonal, we take the square root of both sides:

diagonal = sqrt(89)

The formula for the uncertainty of x, Δx, is given by: Δx = √(\(b^2\) * Δ\(c^2\)/\(a^2\) + \(c^2\) * Δ\(a^2\)/\(a^4\) + \(c^2\) * Δ\(b^2\)/\(a^2\)). To derive the formula for the uncertainty of x when x = c/a * b, we can use partial derivatives.

The uncertainty in x can be determined by considering the uncertainties in c, a, and b and their respective contributions to the overall uncertainty. By applying the rules of error propagation, we can derive a formula that expresses the uncertainty in x based on the uncertainties in c, a, and b.

To derive the formula for the uncertainty of x, we start by considering the relationship between x, c, a, and b: x = c/a * b. Let's denote the uncertainties in c, a, and b as Δc, Δa, and Δb, respectively.

Using the rules of error propagation, we can express the uncertainty in x, Δx, as:

Δx = √\(((\partial x/\partial c * \Delta c)^2 + (\partial x/\partial a * \Delta a)^2 + (\partial x/\partial b * \Delta b)^2)\)

Taking partial derivatives of x with respect to c, a, and b, we have:

∂x/∂c = 1/a * b

∂x/∂a = -c/\(a^2\) * b

∂x/∂b = c/a

Substituting these derivatives into the formula for Δx, we get:

Δx = √\(((1/a * b * \Delta c)^2 + (-c/a^2 * b * \Delta a)^2 + (c/a * \Delta b)^2)\)

Simplifying further, we can rewrite this as:

Δx = √(\(b^2\) * Δ\(c^2\)/\(a^2\) + \(c^2\) * Δ\(a^2\)/\(a^4\)+ \(c^2\) * Δ\(b^2\)/\(a^2\))

Therefore, the formula for the uncertainty of x, Δx, is given by:

Δx = √(\(b^2\) * Δ\(c^2\)/\(a^2\) + \(c^2\)* Δ\(a^2\)/\(a^4\) + \(c^2\) * Δ\(b^2\)/\(a^2\))

This formula allows us to calculate the uncertainty in x based on the uncertainties in c, a, and b.
