The length of HK is equal to: A. √768 units.

In Mathematics and Geometry, Pythagorean's theorem is represented by the following mathematical expression:

z² = x² + y²

Where:

x, y, and z represent the side length of any right-angled triangle.

Based on the diagram for right-angled triangle GHK, we can logically deduce that the height splits GK into 2 parts:

Hypotenuse = 8 units.

Hypotenuse = 32 - 8 = 24 units.

By applying the geometric mean theorem for right-angled triangles, we have:

Height = √(m × n)

Height = √(8 × 24) = √(192) units

In order to determine the length of HK in right-angled triangle GHK, we would have to apply Pythagorean's theorem:

HK² = 192² + 24²

HK² = 192 + 576

HK² = 768

HK = √(768) units.

The value of the probability of selecting a blue marble from the bag is 1/3

The probability of selecting a blue marble can be found by dividing the number of blue marbles by the total number of marbles in the bag.

From the given information, we know that there are 4 blue marbles out of a total of 12 marbles in the bag.

Therefore, the probability of selecting a blue marble is:

Probability of selecting a blue marble = Number of blue marbles / Total number of marbles

This gives

Probability of selecting a blue marble = 4/12

Simplifying the fraction by dividing both the numerator and denominator by 4, we get:

Probability of selecting a blue marble = 1/3

So, the probability of selecting a blue marble from the bag is 1/3 or 0.33 as a decimal.

The statement based on sample size representing true characteristics of qualitative methodology are smaller sample size, qualitative research and theoretical research of qualitative data.

Some general statements about sample size in qualitative methodology are as follow,

Qualitative research typically involves smaller sample sizes than quantitative research.

The sample size in qualitative research is not determined by statistical power calculations.

But rather by theoretical saturation and the quality of data collected.

The goal of qualitative research is to gain a deep understanding of the phenomenon being studied.

Rather than to generalize findings to a larger population.

Qualitative research often involves purposive or convenience sampling rather than random sampling.

All of these statements are generally true characteristics of qualitative methodology.

If any statement contradicts one of these characteristics,

If the number of drinks consumed by a small group is 4, 4, 6, 7, and 8, the number 6 would be the median for that group.

The median is a measure of central tendency in a set of data, and it represents the middle value of the data set when the values are arranged in order. To find the median of a set of data, we follow these steps:

Arrange the data in order from smallest to largest (or from largest to smallest).

If the number of data points is odd, the median is the middle value.

If the number of the data points is even, then the median is the average of the two middle values.

For example, if we have the data set {2, 4, 5, 7, 9}, we would arrange it in order to get {2, 4, 5, 7, 9}. Since there are an odd number of data points (5), the median is the middle value, which is 5.

If we have the data set {2, 4, 5, 7, 9, 10}, we would arrange it in order to get {2, 4, 5, 7, 9, 10}. Since there are an even number of data points (6), the median is the average of the two middle values, which are 5 and 7. Therefore, the median is (5 + 7)/2 = 6.

Explanation:

There are 3 ways to select the single math book and [tex]4\times3\div2 = 12\div2 = 6[/tex] ways to pick the two other books that are either physics or history (order doesn't matter). This is effectively because we have [tex]3+1 = 4[/tex] books that are either physics or history, and we're using the nCr combination formula.

Overall, there are [tex]3\times6 = 18[/tex] ways to select the three books such that one is math, and the other two are either physics or history.

-------------------

There are [tex]3+3+1 = 7[/tex] books total. Since we're selecting 3 of them, we use the nCr formula again and you should get 35.

Or you could note how [tex](7\times6\times5)\div(3\times2\times1) = 210\div6 = 35[/tex]

This says there are 35 ways to select any three books where we can tell the difference between any subject (ie we can tell the difference between the math books for instance).

-------------------

We found there are 18 ways to get what we want out of 35 ways to do the three selections. Therefore, the answer as a fraction is 18/35

Thus, the rectangular fence has a 15-meter width.

We must determine the fence's length. The equation A=lw, where l seems to be the length & w is the width, determines the surface area A of a rectangle.

Let the variable "w" stand in for the rectangular fence's width.

We are aware that the fence's perimeter measures 54 metres in total.

Since a rectangle's opposite sides are identical in length and the fence contains four sides, we may write the following equation to get the perimeter:

(Length + Width)2 = the perimeter

Inputting the values provided yields:

54 = 2(12 + w)

After simplifying and finding "w," we arrive at:

54 = 24 + 2w

2w = 30

w = 15

Hence, the rectangular fence's width is 15 meters.

Answer:

Therefore, for Ruhama's average to be less than 80, the value of x must be less than 80.

Step-by-step explanation:

Let's use the formula for the average (or mean) of a set of numbers: average = (sum of numbers) / (number of numbers)

To find the value of x that makes Ruhama's average less than 80, we need to solve the following inequality:

(75 + 80 + 85 + x) / 4 < 80

Multiplying both sides by 4 gives:

Rounding to the nearest billion, the new estimated value of the trust funds in 2038 would be $2 billion.

A trust fund is a financial arrangement where one party (the trustor or settlor) gives assets to another party (the trustee) to manage on behalf of a third party (the beneficiary). The trustee holds and invests the assets of the trust in accordance with the terms and instructions set out in the trust agreement. Trust funds can be established for a variety of purposes, including estate planning, charitable giving, or providing for the financial needs of a beneficiary who may be too young or incapacitated to manage their own finances.

Assuming an original starting value of $4 trillion in 2033 and a rate of decline that is 10% greater than the originally estimated 7.6% rate, the new rate of decline would be 7.6% + (10% * 7.6%) = 8.36%.

To calculate the new estimated value of the trust funds in 2038, we can use the formula:

Value in 2038 = Starting Value * (1 - Rate of Decline)ⁿ

Plugging in the values, we get:

Value in 2038 = $4 trillion * (1 - 0.0836)⁵

Value in 2038 = $4 trillion * 0.6002

The probability that less than 70 are dissatisfied with their vacation time is  approximately 0.000008.

The normal distribution can be used to approximate this binomial distribution.

The probability that less than 70 are dissatisfied with their vacation time is approximately 0.0082, using the normal curve approximation.

Using the binomial formula:

n = 500

p = 0.16

q = 1 - p = 0.84

We want to find P(X < 70), where X is the number of people out of 500 who are dissatisfied with their vacation time.

P(X < 70) = Σi=0^69 (500 choose i) * 0.16^i * 0.84^(500-i)

Using technology, we can find this probability to be approximately 0.000008.

To show that this distribution can be approximated by the normal distribution, we need to check if the conditions for the normal approximation are met:

np = 500 * 0.16 = 80 ≥ 10

nq = 500 * 0.84 = 420 ≥ 10

Since both conditions are met, we can use the normal distribution to approximate this binomial distribution.

To use the normal curve to approximate the probability that less than 70 are dissatisfied with their vacation time, we need to standardize the binomial distribution:

μ = np = 80

σ = sqrt(npq) = sqrt(500 * 0.16 * 0.84) ≈ 4.58

We want to find P(X < 70), which is equivalent to finding the probability that a standard normal variable Z is less than (69.5 - 80) / 4.58 = -2.37.

Using a standard normal table or technology, we find this probability to be approximately 0.0082.

To solve the inequality, we need to isolate the variable, x. First, we can simplify the expression by adding 3y to both sides:

-3y + 7x ≥ -3y - 14 + 3y

Simplifying the right side, we get:

-3y + 7x ≥ -14

Next, we can isolate x by subtracting 3y from both sides:

-3y + 7x - 3y ≥ -14 - 3y

Simplifying the left side, we get:

4x ≥ -14 - 3y

Finally, we can isolate x by dividing both sides by 4:

x ≥ (-14 - 3y) / 4

Therefore, the solution to the inequality is:

x ≥ (-14 - 3y) / 4

Note that the inequality sign remains the same because we did not multiply or divide by a negative number.

The required answers are 80.8, 79,and g(42) > f(42).

Part A:

To determine the test average for the math class after completing test 2, we need to evaluate the function f(x) at x=2. That is,

[tex]$$f(2) = 0.9(2) + 79 = 80.8$$[/tex]

Therefore, the test average for the math class after completing test 2 is 80.8.

Part B:

To determine the test average for the science class after completing test 2, we need to find the equation of the linear function g(x) that passes through the given points (1,78) and (2,79). The slope of the line passing through these points is

[tex]$m=\frac{y_2-y_1}{x_2-x_1}=\frac{79-78}{2-1}=1$$[/tex]

We can use the point-slope form of a line to find the equation of the line passing through the point (1,78) with slope m=1. That is,

[tex]$$y-78 = 1(x-1)$$[/tex]

Simplifying, we get

y = x + 77

Therefore, the test average for the science class after completing test 2 is

g(2) = 2 + 77 = 79

Part C:

To determine which class had a higher average after completing test 42, we need to evaluate f(42) and g(42) and compare the results. We have

[tex]$$f(42) = 0.9(42) + 79 = 117.8$$[/tex]

To find (42), we need to extend the linear function g(x) beyond the given data points by assuming that the function is linear and continues with the same slope m=1. That is,

g(x) = x + 77

for all [tex]$x\geq 1$[/tex]. Therefore,

[tex]$$g(42) = 42 + 77 = 119$$[/tex]

Since g(42) > f(42), we conclude that the science class had a higher average after completing test 42.

What do you mean by Taylor's series ?

The Taylor's series is a way to represent a function as a power series, which is a sum of terms involving the variable raised to increasing powers. The series is centered around a specific point, called the center of the series. The Taylor's series approximates the function within a certain interval around the center point.

The general formula for the Taylor's series of a function f(x) centered at [tex]x = a[/tex] is:

[tex]f(x) = f(a) + f'(a)(x-a) + f''(a)(x-a)^2/2! + f'''(a)(x-a)^3/3! + ...[/tex]

where [tex]f'(a), f''(a), f'''(a),[/tex] etc. are the derivatives of f(x) evaluated at [tex]x = a[/tex].

Finding the Taylor's series for [tex]1 + 3e^x + x^2[/tex] at [tex]x=0[/tex] :

We need to find the derivatives of the function at [tex]x=0[/tex]. We have:

[tex]f(x) = 1 + 3e^x + x^2[/tex]

[tex]f(0) = 1 + 3e^0 + 0^2 = 4[/tex]

[tex]f'(x) = 3e^x+ 2x[/tex]

[tex]f'(0) = 3e^0 + 2(0) = 3[/tex]

[tex]f''(0) = 3e^0 + 2 = 5[/tex]

[tex]f'''(x) = 3e^x[/tex]

[tex]f'''(0) = 3e^0 = 3[/tex]

Substituting these values into the general formula for the Taylor's series, we get:

[tex]f(x) = f(0) + f'(0)x + f''(0)x^2/2! + f'''(0)x^3/3! + ...[/tex]

[tex]f(x) = 4 + 3x + 5x^2/2 + 3x^3/6 + ...[/tex]
