Answer this wuestion for me man

Answer:

3

Step-by-step explanation:

First right out all the data in numerical order from left to right.

2, 2, 2, 3, 4, 5, 7

The median is the middle number in the set.  If there is an even amount of data points, find the average of the two middle numbers.  If there is an odd number of data points, like in this data set, just take the middle number as you median.

There are 7 data points in this set so the fourth number in the set written in numerical order would be your median.

When writing this set out in numerical order, repeated numbers must be repeated, we find that the fourth, or middle, number is 3.  Therefore, 3 is the median of this data set.

In order to generalize about a population using data from a sample, researchers should employ appropriate sampling techniques to ensure representative and unbiased results.

By using random sampling methods and ensuring an adequate sample size, researchers can increase the likelihood of accurate population generalization.

When researchers want to make inferences about a population based on data collected from a sample, it is crucial to use proper sampling techniques. Random sampling is widely considered the best approach to achieve representativeness. By randomly selecting individuals from the population, researchers can minimize bias and increase the likelihood of obtaining a sample that accurately reflects the population's characteristics.

Additionally, the sample size plays a crucial role in generalization. A larger sample size generally provides more reliable estimates of population parameters. With a larger sample, there is a higher chance of capturing the diversity and variability present in the population, reducing the margin of error in the generalizations made.

Furthermore, researchers should consider the sampling frame—the list or source from which the sample is drawn. The sampling frame should be comprehensive and include all members of the population of interest. If the sampling frame is incomplete or biased, it can lead to inaccurate generalizations.

In summary, to generalize about a population using data from a sample, researchers should employ random sampling techniques, ensure an adequate sample size, and use a comprehensive and unbiased sampling frame. These practices increase the likelihood of obtaining representative and reliable results, enabling accurate generalizations about the larger population.

Answer:

432 square centimeters

Step-by-step explanation:

Given :

The circumference of a hub cap is = 73.66 cm

The circumference of a circle is given as = 2πr, where r is the radius of the circular hubcap.

So , 2πr = 73.66

     ⇒ \($r=\frac{73.66}{2 \times \pi}$\)

      ⇒ \($r=\frac{73.66}{2 \times 3.14}$\)        (Using, π = 3.14)

     ⇒ r = 11.73 cm

Therefore the area of the hub cap is given by A = \($\pi r^2$\)

A = \($3.14 \times 11.73 \times 11.73$\)

   = 432 \($cm^2$\)

If the circumference of the hubcap were smaller, the area of the hubcap would be smaller too, since the circumference of the hubcap is proportional to the radius which is proportional to the area too.

We will apply the Pythagoras theorem to find the measure of the unknown leg in a triangle when one leg and the hypotenuse are provided dimensions.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometric function.

According to Pythagoras, the sum of the squares of two sides equals the square of the longest side.

\(\rm h^2 = p^2+ b^2\)

Where,

a) Alexandra's fortnightly repayments would be approximately $345.85.

b) The outstanding balance on the loan after 6 fortnights would be approximately $1,726.17.

To calculate Alexandra's fortnightly repayments and the outstanding balance on the loan after 6 fortnights, we need to use the formula for calculating the repayment amount and the formula for the outstanding balance.

a) Fortnightly Repayments:

First, we need to calculate the interest rate per fortnight. The annual interest rate is 8.12%, so the fortnightly interest rate would be (8.12% / 26) = 0.3123%.

The formula to calculate the repayment amount on a loan is:

Repayment Amount = \(P \times (r \times (1 + r)^n) / ((1 + r)^n - 1)\)

Where:

P = Principal amount of the loan ($2000)

r = Interest rate per fortnight (0.3123%)

n = Number of fortnights (6)

Plugging in the values:

Repayment Amount = \(2000 \times (0.003123 \times (1 + 0.003123)^6) / ((1 + 0.003123)^6 - 1)\)

Repayment Amount ≈ $345.85

b) Outstanding Balance after 6 Fortnights:

The formula to calculate the outstanding balance on a loan is:

Outstanding Balance = \(P \times ((1 + r)^n) - (A \times (((1 + r)^n) - 1) / r))\)

Where:

P = Principal amount of the loan ($2000)

r = Interest rate per fortnight (0.3123%)

n = Number of fortnights (6)

A = Repayment amount ($345.85)

Plugging in the values:

Outstanding Balance = \(2000 \times ((1 + 0.003123)^6) - (345.85 \times (((1 + 0.003123)^6) - 1) / 0.003123)\)

Step-by-step explanation:

The length of AG is approximately 34.47 mm to 2 decimal places.

what is length ?

In mathematics, length is a measure of distance along a straight line or curve. It is a fundamental concept in geometry and is defined as the distance between two points in space.

what is decimal places ?

In mathematics, decimal places refer to the number of digits that appear after the decimal point in a number expressed in decimal form.

In the given question,

To find the length of AG, we can use trigonometry and the given angles. Let's label some points on the diagram:

Let O be the center of square aehd, and let M be the midpoint of AD.

We can see that triangle AOG is a right triangle, since AO and OG are perpendicular (because square aehd is perpendicular to square bfgc). Therefore, we can use trigonometry to find the length of AG.

First, let's find the length of OM. Since M is the midpoint of AD, we know that OM = AD/2 = 21 mm.

Next, let's find the length of AM. We can use trigonometry and the given angles:

tan(27) = AM/AG => AM = AG * tan(27)

tan(36) = AM/OM => AM = OM * tan(36)

Therefore, we can combine these two equations to find AG:

AG * tan(27) = OM * tan(36)

AG = OM * tan(36) / tan(27)

AG = 21 * tan(36) / tan(27)

AG ≈ 34.47 mm (rounded to 2 decimal places)

Therefore, the length of AG is approximately 34.47 mm to 2 decimal places.

Answer: -50

Step-by-step explanation:

5 - 6 / 5p = 125 degrees

1/2p = ?

First, subtract 5 from both sides, that way, the 5 on the left side will cancel out.

-6/5p = 125-5 degrees

-6/5p = 120 degrees

now, multiply 5p on both sides.

-6 = 120 * 5p degrees

-6 = 600p degrees

divide 600 on both sides

-6/600 = p degrees

-0.01 = p degrees

p = -0.01

1/2p = 1 / -0.02 = -50

To calculate the derivative of the function h(x) = √(√(e^(2x) + e^2)), we can apply the chain rule and the power rule of differentiation. Let's break down the process step by step.

First, we can rewrite the function h(x) as h(x) = (e^(2x) + e^2)^(1/4)^(1/2). Now, applying the chain rule, we differentiate the outer function with respect to the inner function, and then multiply it by the derivative of the inner function. The derivative of the inner function, e^(2x) + e^2, with respect to x is 2e^(2x).

Putting it all together, the derivative of h(x) is:

h'(x) = (1/2) * (e^(2x) + e^2)^(-3/4) * 2e^(2x)

     = e^(2x) * (e^(2x) + e^2)^(-3/4).

Thus, the derivative of h(x) is e^(2x) times the quantity (e^(2x) + e^2)^(-3/4).

We can use either one tailed or two tailed as our interest.

The coefficient of determination (R-squared) measures the proportion of the variance in the dependent variable that can be explained by the independent variables in a regression model. It ranges from 0 to 1, where 0 indicates no relationship and 1 indicates a perfect fit.

When conducting a hypothesis test for the significance of the coefficient of determination, you typically assess whether R-squared is significantly different from zero. This is done using a one-tailed test, as the alternative hypothesis is usually stated as either "R-squared is greater than zero" or "R-squared is less than zero."

Thınking about testing the significance of the coefficient of determination, we set up the hypothesis test. This is data from the given question

A. The equation that can be used to determine the number of weeks is $999=225+42w

B. The number of weeks it will take Hannah to repay is 18weeks

An equation is a mathematical statement, which has an equal sign (=) between the algebraic expression. Linear equations are the equations of degree 1. It is the equation for the straight line. The solutions of linear equations will generate values, which when substituted for the unknown values, make the equation true. In the case of one variable, there is only one solution. For example, the equation x + 3 = 0 has only one solution as x = -2.

the total amount of money Hannah repaid is $225+$43×w, where w is the number of weeks to repay $43.

therefore $999= $225+$43w

$43w=$ (999+225)

$43w= $1224

divide both side by $43

w= $1224/$43

w= 18 weeks

The integral ∫10x^p * ln(x) dx converges for all values of p except p = -1.

To determine the values of p for which the integral ∫10x^p * ln(x) dx converges, we need to consider the convergence of the integrand for different values of p. The integral will converge if the integrand is well-behaved and does not exhibit any divergence.

Let's analyze the integrand in two separate cases:

Case 1: p ≠ -1

When p ≠ -1, the integrand is well-defined for all x > 0. We can proceed with evaluating the integral.

∫10x^p * ln(x) dx = [x^(p+1) * ln(x)] / (p+1) + C

To calculate the value of the integral for a specific value of p, we can substitute the limits of integration into the antiderivative expression and evaluate the resulting expression.

Case 2: p = -1

When p = -1, the integrand becomes 10x^(-1) * ln(x), which poses a potential issue at x = 0. To determine if the integral converges for this case, we need to examine the behavior of the integrand near x = 0.

As x approaches 0, the expression ln(x) approaches negative infinity, which would cause the integrand to diverge. Therefore, for p = -1, the integral does not converge.

In summary, the integral ∫10x^p * ln(x) dx converges for all values of p except p = -1.

Please note that when evaluating the definite integral for specific limits of integration, you should substitute the limits into the antiderivative expression and then calculate the difference of the resulting expressions evaluated at the upper and lower limits.

1. The area of the scale drawing of the park is 146,880 square inches (Option J).

2. The perimeter of the park is 126 feet (Option D).

3. The length of the south side of the park is 40% of the length of the north side (Option F).

1. To find the area of the scale drawing of the park, we need to calculate the area of the trapezium. The formula for the area of a trapezium is (base1 + base2) * height / 2.

Using the scale, the lengths of the bases (parallel sides) in feet would be:

Base1 = 28 inches * 1.5 feet/inch = 42 feet

Base2 = 40 inches * 1.5 feet/inch = 60 feet

Plugging in the values into the formula, we have:

Area = (42 + 60) * 16 / 2 = 1020 square feet

Since the answer options are in square inches, we need to convert the area back to square inches:

Area = 1020 square feet * 144 square inches/square foot = 146880 square inches

Therefore, the area of the scale drawing of the park is 146880 square inches.

2. The perimeter of the park can be calculated by summing up the lengths of all sides.

The lengths of the sides in feet would be:

Side1 = 28 inches * 1.5 feet/inch = 42 feet

Side2 = 40 inches * 1.5 feet/inch = 60 feet

Side3 = 16 inches * 1.5 feet/inch = 24 feet

Adding up all sides, we have:

Perimeter = Side1 + Side2 + Side3 = 42 feet + 60 feet + 24 feet = 126 feet

Therefore, the perimeter of the park is 126 feet.

3. To find the percentage length of the south side compared to the north side, we can calculate:

Percentage = (South Side Length / North Side Length) * 100

Using the scale, the length of the south side in feet would be:

South Side Length = 16 inches * 1.5 feet/inch = 24 feet

The length of the north side is already given as 40 inches * 1.5 feet/inch = 60 feet.

Plugging in the values, we have:

Percentage = (24 feet / 60 feet) * 100 = 40%

Therefore, the length of the south side of the park is 40% of the length of the north side.

where  μ = The mean of the distribution

σ = the standard deviation of the distribution

Here

μ = 2727

σ = 33

We need to find

P(2121< x < 3030)

We know that the relation between a normal distribution and its Z-score is

P(a < X < b) = Φ((b- μ)/ σ)  -  Φ(a - μ/ σ)

here a = 2121  and  b = 3030

Therefore we get

P(2121< x < 3030) = Φ((3030- 2727)/ 33)  -  Φ(2121 - 2727/ 33)

= Φ((303)/ 33)  -  Φ(-606/ 33)
