Answer:

9.0 ft (nearest tenth)

Step-by-step explanation:

The chord is the base of an isosceles triangle with sides of the radius.

To calculate the approximate distance of the chord from the center of the circle, we need to find the height of this triangle.

\(\sf height=\sqrt{s^2-(\frac{b}{2})^2}\)

(where s is the side length and b is the base length of an isosceles triangle)

Given:

\(\begin{aligned}\implies \sf height & =\sqrt{10.8^2-\left(\frac{12}{2}\right)^2}\\ & = \sqrt{116.64-36}\\ & = \sqrt{80.64}\\ & = 8.979977728...\\ & = 9.0\: \sf ft\:(nearest\:tenth) \end{aligned}\)

About two-thirds of aluminum cans are recycled today. Aluminum cans are the most sustainable beverage package on virtually every measure.

According to the Can Manufacturers Institute, aluminum cans are recycled at a rate of 63.6% in the United States in 2019. This means that more than two-thirds of aluminum cans are recycled, which makes aluminum cans one of the most recycled beverage containers in the world.

In the recycling process, the aluminum is shredded, melted, and formed into blocks called ingots. These ingots can be used to make new aluminum cans, which saves energy and conserves natural resources.

Aluminum cans are infinitely recyclable, which means they can be recycled repeatedly without losing quality. Recycling one aluminum can saves enough energy to power a TV for three hours, and it saves enough energy to light a 100-watt bulb for 20 hours.

P(X > 20) has a rounded value of 0.0475.

By dividing the sum of the given numbers by the entire number of numbers, the mean—the average of the given numbers—is determined.

To find P(X > 20), where X is a normal random variable with mean μ = 15 seconds and standard deviation σ = 3 seconds, we need to standardize the variable and use the standard normal distribution.

Let Z be a standard normal random variable, then we can standardize X as follows:

Z = (X - μ) / σ = (20 - 15) / 3 = 1.67

Using a standard normal table or calculator, we can find the probability:

P(Z > 1.67) = 0.0475 (rounded to four decimal places)

Therefore, P(X > 20) has a rounded value of 0.0475.

The statement ''The bottom-up approach to metrics yield the most easily obtainable metrics however many metrics collected in this approach may not be suitable for top-management.'' is true because the bottom-up approach to metrics focuses on collecting data and metrics at lower levels within an organization, such as individual departments or teams.

These metrics are typically more operational and task-oriented, providing detailed insights into specific areas of the business.

However, while the bottom-up approach yields easily obtainable metrics, many of these metrics may not be directly relevant or suitable for top-management decision-making.

Top management typically requires high-level, strategic metrics that align with organizational goals and provide a holistic view of performance.

To cater to the needs of top management, a top-down approach is often employed, which involves identifying key strategic metrics and aligning them with organizational objectives.

This approach ensures that the metrics collected are meaningful, actionable, and support informed decision-making at the executive level.

Answer:

D can be used

Step-by-step explanation:

Based on the given information, the predicted value can be calculated by adding the residual to the observed value. In this case, the predicted value is 30.5.

To determine the predicted value, we need to add the residual to the observed value. The residual represents the difference between the observed value and the predicted value. In this scenario, the residual is given as 0.6, and the observed value is 29.9. Adding the residual of 0.6 to the observed value, we get the predicted value of 30.5.

The predicted value is obtained by considering the residual as an adjustment to the observed value. It represents the estimated value based on the available data. In this case, the residual of 0.6 indicates that the predicted value is slightly higher than the observed value. The addition of the residual to the observed value accounts for any systematic deviation or error in the prediction. Therefore, the predicted value is 30.5.

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.

Answer:

x=10, y=24

\(\left(34-y\right)^2+y^2=676\)

Step-by-step explanation:

Answer:

x = 10 and y = 24

Step-by-step explanation:

Perimeter of triangle = sum of the 3 sides of the triangle

:. x + y + 26 = 60

x + y = 60 - 26

x + y = 34 ---- (1)

From Pythagoras theorem,

x² + y² = 26²

x² + y² = 676 ---- (2)

From equation (1): y = 34 - x

:. x² + (34 - x)² = 676

x² + 1,156 - 68x + x² = 676

x² + x² - 68x + 1,156 - 676 = 0

2x² - 68x + 480 = 0

x² - 34x + 240 = 0

(x² - 24x) - (10x + 240) = 0

x(x - 24) -10(x - 24) = 0

(x - 24)(x - 10) = 0

x = 24 or 10

y = 34 - x

y = 34 - 10 = 24

  Ans: 23

Answer:

Step-by-step explanation:

You want values of ∆y and dy for y = x² -6x and x = 5, ∆x = dx = 0.5.

The value of dy is found by differentiating the function.

  y = x² -6x

  dy = (2x -6)dx

For x=5, dx=0.5, this is ...

  dy = (2·5 -6)(0.5) = (4)(0.5)

  dy = 2

The value of ∆y is the function difference ...

  ∆y = f(x +∆x) -f(x) . . . . . . . where y = f(x) = x² -6x

  ∆y = (5.5² -6(5.5)) -(5² -6·5)

  ∆y = (30.25 -33) -(25 -30) = -2.75 +5

  ∆y = 2.25

Additional comment

On the attached graph, ∆y is the difference between function values:

  ∆y = -2.75 -(-5) = 2.25

and dy is the difference between the linearized function value and the function value:

Step-by-step explanation:

The dimension of the column space of A is 3.

How the dimension of the column space of A is 3?

The rank-nullity theorem states that for any matrix A, the sum of the dimensions of the null space and the column space is equal to the number of columns in A, i.e.,

dim Null A + dim Col A = number of columns in A

In this case, we have a 8 × 7 matrix A, so the number of columns in A is 7. We are also given that the null space of A is 4-dimensional, i.e., dim Null A = 4. Using the rank-nullity theorem, we can find the dimension of the column space of A:

dim Col A = number of columns in A - dim Null A

dim Col A = 7 - 4

dim Col A = 3

Therefore, the dimension of the column space of A is 3.

The dependent variable must be continuous in order to conduct an ANOVA (Analysis of Variance) test.

Let me briefly explain the key terms and reasoning:
Dependent variable:

This is the outcome variable that you are measuring in an experiment or study.

It depends on the independent variable(s), which are the factors you manipulate or observe to determine their effect on the dependent variable.
Continuous variable:

A continuous variable is a numerical variable that can take on an infinite number of values within a given range. Examples include weight, height, and temperature.
ANOVA:

ANOVA is a statistical method used to compare the means of two or more groups to determine if there are significant differences between them.

It evaluates the effect of one or more independent variables on a continuous dependent variable.
To conduct an ANOVA, the dependent variable must be continuous because the test relies on calculating the variance within and between groups.

The variance is a measure of dispersion or spread of the continuous data.

If the dependent variable were not continuous, it would be difficult to quantify the differences between group means, making it impossible to determine if the independent variable(s) had a significant effect.
ANOVA test, the dependent variable must be continuous, allowing for the calculation of variances and comparison of group means to determine any significant differences based on the effect of the independent variable(s).
