Qualitative with 2 possible outcomes of variable is required to construct a confidence interval for a population proportion.

The goal of qualitative research is to collect and analyze non-numerical (descriptive) data in order to comprehend people's attitudes, beliefs, and motivations in relation to their social reality. In-depth interviews, focus groups, or observations are frequently used in this kind of study to gather the information that is rich in context and detail.

To investigate complicated phenomena or to learn more about people's viewpoints and experiences on a certain subject, qualitative research is frequently used. It is especially helpful for academics who wish to comprehend the meaning that individuals attribute to their experiences or who want to identify the fundamental causes of people's conduct. Ethnography, grounded theory, discourse analysis, and interpretative phenomenological analysis are examples of qualitative approaches.

The estimate for the instantaneous rate of change at I = 2 is 30, with an error margin of 10%.

To estimate the instantaneous rate of change at I = 2, we need to know the function that describes the relationship between the variables. Let's assume we have a function f(I) and we want to estimate the derivative of f with respect to I at I = 2.

One way to estimate the instantaneous rate of change at I = 2 is to use the limit definition of the derivative

f'(2) = lim h->0 (f(2+h) - f(2))/h

here h is a small value close to zero. We want our estimate to be within 10% of the exact answer, so we can choose h to be 10% of the distance from 2 to the nearest data point in the function. For example, if the function is given by a table of values and the nearest data point to 2 is at I = 1.8, we can choose h to be 0.02.

Using this value of h, we can calculate the estimate of the derivative:

f'(2) ≈ (f(2+0.02) - f(2))/0.02

We can then use the actual function values to compute the estimate. For example, if f(2+0.02) = 4.6 and f(2) = 4.0, then the estimate would be:

f'(2) ≈ (4.6 - 4.0)/0.02 = 30

Step-by-step explanation:

The prism would have a capacity of about 2598 cubic units, which should be enough to hold about 1000 beads assuming each bead has a volume of 1 cubic unit.

To determine what measurements Angela could choose for the prism base and height, we need to consider the formula for the volume of a hexagonal prism, which is:

Volume = (3/2) × (sqrt(3)/2) × s² × h × n

where:

s = length of one side of the hexagon base

h = height of the prism

n = number of sides of the base polygon (in this case, n = 6 for a hexagon)

We know that Angela wants the prism to hold about 1000 beads, but we don't know the volume of a single bead. Let's assume for the sake of simplicity that each bead has a volume of 1 cubic unit. Therefore, to hold 1000 beads, the prism needs to have a volume of 1000 cubic units.

We can use this information to set up an equation:

1000 = (3/2) × (sqrt(3)/2) × s² × h × 6

Simplifying this equation, we get:

1000 = 4.59808 × s² × h

We can use this equation to find different combinations of s and h that satisfy the equation and result in a prism with a volume of about 1000 cubic units. Here are a few possible combinations:

s = 10 units, h = 4.34 units

s = 12 units, h = 3.06 units

s = 15 units, h = 2.05 units

Note that there are many other possible combinations of s and h that could result in a prism with a volume of about 1000 cubic units.

To find the prism's volume or capacity, we can use the formula for the volume of a hexagonal prism that we used earlier:

Volume = (3/2) × (sqrt(3)/2) × s² × h × n

For example, if Angela chooses a base with a side length of 10 units and a height of 4.34 units, the volume of the prism would be:

Volume = (3/2) × (sqrt(3)/2) × 10² × 4.34 × 6

Volume ≈ 2598 cubic units

Therefore, the prism would have a capacity of about 2598 cubic units, which should be enough to hold about 1000 beads assuming each bead has a volume of 1 cubic unit.

The second is kinda blurry, so it's a little hard to explain.

The expression (-9x)^4 can be represented as -6561x^3 without using exponents.

To express the expression (-9x)^4 without using exponents, we can expand it by multiplying the base (-9x) four times using the multiplication property.

(-9x)^4 = (-9x) * (-9x) * (-9x) * (-9x)

To simplify this expression, we can multiply the terms together, taking care to apply the rules of multiplication:

(-9x) * (-9x) = (-9 * -9) * (x * x) = 81 * x^2 = 81x^2

So, by substituting this result back into the original expression, we get:

(-9x)^4 = 81x^2 * (-9x) = -6561 x^3

Therefore, the expression (-9x)^4 can be represented as -6561x^3 without using exponents.

Answer:

1191 cm²

Step-by-step explanation:

Area of parallelogram = base X vertical height.

Call the vertical line h.

h/ sin 80  =  7/ sin 10

h = (7 sin 80) / sin 10

= 39.7.

Area of parallelogram = 30 X 39.7

= 1191 cm²

The Area of Parallelogram whose side length is 30 cm is 1,190.952 square cm.

Given:

Side length = 30 cm

Using Trigonometry

tan 80 = P / Base

5.6712 = P / 7

P = 39.6984 cm

Using the formula for Area of parallelogram

= Base x height

= 30 x 39.6984

= 1,190.952 square cm.

Therefore, the area is 1,190.952 square cm.

Step-by-step explanation:

27000×0.21=5670

a) The algebraic fraction \(\frac{{x + 2}}{{(x - 1)^2}}\) is proper. b) The algebraic fraction \(\frac{{4x^2 - 31x + 59}}{{(x - 4)^2}}\) can be expressed as \(-\frac{{31}}{{x - 4}} - \frac{{25}}{{(x - 4)^2}}\).

Let's solve each part step by step and determine whether the fraction is proper or improper, and then express it accordingly.

a) \(\frac{{x + 2}}{{(x - 1)^2}}\):

Step 1: Determine the degree of the numerator and the denominator:

  - Degree of the numerator = 1 (linear term)

  - Degree of the denominator = 2 (quadratic term)

Since the degree of the numerator is less than the degree of the denominator, the fraction is proper.

Step 2: Express the proper fraction in partial fractions:

\(\frac{{x + 2}}{{(x - 1)^2}} = \frac{A}{{x - 1}} + \frac{B}{{(x - 1)^2}}\).

Step 3: Find the values of A and B:

Multiply both sides of the equation by \(((x - 1)^2)\) to eliminate the denominators:

  (x + 2) = A(x - 1) + B.

Expand the equation and collect like terms:

  x + 2 = Ax - A + B.

Equate the coefficients of like terms:

  Coefficient of x: 1 = A.

  Constant term: 2 = -A + B.

Solve the system of equations to find the values of A and B:

From the coefficient of x, A = 1.

Substituting A = 1 into the constant term equation: 2 = -1 + B, we find B = 3.

Therefore, the partial fraction decomposition is:

  \(\frac{{x + 2}}{{(x - 1)^2}} = \frac{1}{{x - 1}} + \frac{3}{{(x - 1)^2}}\).

b) \(\frac{{4x^2 - 31x + 59}}{{(x - 4)^2}}\):

Step 1: Determine the degree of the numerator and the denominator:

  - Degree of the numerator = 2 (quadratic term)

  - Degree of the denominator = 2 (quadratic term)

Since the degree of the numerator is equal to the degree of the denominator, the fraction is proper.

Step 2: Express the proper fraction in partial fractions:

  \(\frac{{4x^2 - 31x + 59}}{{(x - 4)^2}} = \frac{A}{{x - 4}} + \frac{B}{{(x - 4)^2}}\).

Step 3: Find the values of A and B:

Multiply both sides of the equation by \(((x - 4)^2)\) to eliminate the denominators:

  (4x^2 - 31x + 59) = A(x - 4) + B.

Expand the equation and collect like terms:

  4x^2 - 31x + 59 = Ax - 4A + B.

Equate the coefficients of like terms:

Coefficient of \(x^2\): 4 = 0 (No \(x^2\) term on the right side).

Coefficient of x: -31 = A.

Constant term: 59 = -4A + B.

Solve the system of equations to find the values of A and B:

From the coefficient of x, A = -31.

Substituting A = -31 into the constant term equation: 59 = 4(31) + B, we find B = -25.

Therefore, the partial fraction decomposition is:

  \(\frac{{4x^2 - 31x + 59}}{{(x - 4)^2}} = -\frac{{31}}{{x - 4}} - \frac{{25}}{{(x - 4)^2}}\).

The above steps provide the solution for each part, including determining if the fraction is proper or improper and expressing it in partial fractions.

Neither of the equation represent the a line that passes through (0, 5) and (4, 15)

The equation of a line can be represented in slope intercept form and point slope form as follows:

slope intercept form:

y = mx + b

where

Therefore,

m = 15 - 5 / 4 - 0

m = 10 / 4

m = 5 / 2

let's find y-intercept using (0, 5)

y = 5 / 2 x + b

5 = 5 / 2(0) + b

b = 5
