Answer:
see explanation
Step-by-step explanation:
the inscribed angle ADB is half the arc that subtends it , AB , then
AB = 2 × ∠ ADB = 2 × 46° = 92°
the central angle BOC is equal to the arc that subtends it, BC , so
BC = 22°
Then
ABC = AB + BC = 92° + 22° = 114°
-----------------------------------------------------
BD is a diameter of the circle , so BAD = 180° THEN
AD = 180° - AB = 180° - 92° = 88°
-----------------------------------------------------
the sum of the arcs on a circle = 360° , so
ADC = 360° - ABC = 360° - 114° = 246°
a rectangle of 24 1/2 sqaure feet if the length of the rectangle is 4 3/8 feet what is the width in feet
A rectangle of 24 1/2 sqaure feet if the length of the rectangle is 4 3/8 feet, and the width of the rectangle is 4 feet.
What is the area of the rectangle?
To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.
To find the width of the rectangle, we can use the formula for the area of a rectangle:
Area = Length x Width
We are given that the area of the rectangle is 24 1/2 square feet and the length is 4 3/8 feet. Substituting these values into the formula, we get:
24 1/2 = 4 3/8 x Width
To solve for the width, we can first convert both mixed numbers to improper fractions:
24 1/2 = 49/2
4 3/8 = 35/8
Substituting these values, we get:
49/2 = 35/8 x Width
To solve for Width, we can cross-multiply:
49/2 * 8/35 = Width
Simplifying, we get:
4 = Width
Therefore, the width of the rectangle is 4 feet.

Define and distinguish among positive correlation, negative correlation, and no correlation. How do we determine the strength of a correlation?
Define positive correlation. Choose the correct answer below.
A.
Positive correlation means that both variables tend to increase (or decrease) together.
B.
Positive correlation means that there is a good relationship between the two variables.
C.
Positive correlation means that two variables tend to change in opposite directions, with one increasing while the other decreases.
D.
Positive correlation means that there is no apparent relationship between the two variables.
Positive correlation means that both variables tend to increase (or decrease) together. Thus, Option A is the answer.
Positive correlation refers to a relationship between two variables in which an increase in one variable is associated with an increase in the other variable. Negative correlation, on the other hand, refers to a relationship in which an increase in one variable is associated with a decrease in the other variable. No correlation means that there is no relationship between the two variables.
To determine the strength of a correlation, we can use a statistical measure called the correlation coefficient, which ranges from -1 to 1. A correlation coefficient of 1 indicates a perfect positive correlation, a correlation coefficient of -1 indicates a perfect negative correlation, and a correlation coefficient of 0 indicates no correlation.

Based on the concept of measurement, the decimal equivalent is 0.75.
To start, it is important to understand that time is a form of measurement that can be expressed in a variety of ways, including hours, minutes, seconds, and even fractions of seconds. Decimals are also a common way to express time, especially in situations where precision and accuracy are important.
To convert 45 minutes into a decimal, you need to first understand the relationship between minutes and hours.
There are 60 minutes in one hour, which means that 45 minutes is equivalent to 0.75 hours
=> (45/60 = 0.75).
Once you have this decimal equivalent, you can express it in a variety of ways, depending on the context.
If you were measuring time in terms of a workday (i.e. 8 hours), 0.75 hours would be equal to 45 minutes. On the other hand, if you were measuring time in terms of a percentage of an hour (i.e. 100%), 0.75 hours would be equal to 75%.

to use pythagorean Theorem
Step-by-step explanation:
The Pythagorean Theorem is a formula that allows you to calculate the distance between two points in a coordinate plane. It states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other two sides. In the case of two points on a coordinate grid, the distance between them is the length of the hypotenuse of the right triangle formed by the horizontal and vertical distances between the two points.

What are transverse angles?Transversal angles are angles that are formed when a transversal line intersects two other lines in a plane. A transversal is a line that intersects two or more other lines, which are called the base lines.
When a transversal intersects two parallel lines, it creates eight angles. These angles can be classified into three types:
Corresponding angles: Pairs of angles that are on the same side of the transversal and in corresponding positions relative to the parallel lines. Corresponding angles are congruent when the parallel lines are cut by the transversal.
Alternate interior angles: Pairs of angles that are on opposite sides of the transversal and between the parallel lines. Alternate interior angles are congruent when the parallel lines are cut by the transversal.
Alternate exterior angles: Pairs of angles that are on opposite sides of the transversal and outside the parallel lines. Alternate exterior angles are congruent when the parallel lines are cut by the transversal.

Zach's living room is 8 yards wide and 9 yards long. He wants to install green carpet that costs $7. 00 per square yard. How much will it cost to buy enough carpet for the living room?
The cost will be $504.00 to buy enough carpet for Zach's living room.
To determine the cost of the carpet for Zach's living room, we first need to calculate the area of the room. The area of a rectangle is found by multiplying the length by the width. In this case, the length is 9 yards and the width is 8 yards:
Area = 9 yards × 8 yards = 72 square yards
Now that we know the area of the room, we can calculate the cost of the carpet. The carpet costs $7.00 per square yard, so we multiply the area of the room by the cost per square yard:
Cost = 72 square yards × $7.00 per square yard = $504.00
Therefore, it will cost $504.00 to buy enough carpet for Zach's living room.

A car takes 2 hours to cover the distance between 2 cities. If her average speed decreased by 20 km/h, it would take 30 minutes longer. What is the distance between the two cities?
(Only accurate answers please)
Answer:
200 km
Step-by-step explanation:
Let's use the formula:
distance = rate × time
Let the original average speed of the car be r km/h, and let the distance between the two cities be d km.
According to the problem, the car takes 2 hours to cover the distance, so we have:
d = r × 2
If the car's average speed decreased by 20 km/h, its new average speed would be (r - 20) km/h. If it took 30 minutes (0.5 hours) longer to cover the same distance at the slower speed, we have:
d = (r - 20) × 2.5
Now we have two equations for d:
d = r × 2
d = (r - 20) × 2.5
We can solve for r in the first equation:
r = d / 2
Substituting into the second equation:
d = (d/2 - 20) × 2.5
Simplifying:
d = 1.25d - 50
0.25d = 50
d = 200
Therefore, the distance between the two cities is 200 km.

Regression Line:
Regression is a statistical technique used in finance, investing, and other fields that attempts to determine the strength and nature of the relationship between one dependent variable (usually denoted Y) and several other variables (called independent variables).
Simple linear regression:
Y = a + bX+ u
Multiple linear regression:
Y = a + b₁ X₁ + b₂ X₂ + b₃ X₃ +..... + bₙ Xₙ +u
where:
Y = The dependent variable that can be predicted.
X =The independent variables that are used to predict
a = The y-intercept
b (beta coefficient) = is the slope of the independent variable(s)
u = The error term
Regression equation:
Regression equations are used in statistics to determine if there is any relationship between data sets. For example, if you measure a child's height every year, you'll find that they grow about 3 inches each year. This trend (growth of 3 inches per year) can be modeled using a regression equation. In fact, most things in the real world (from oil prices to hurricanes) can be modeled with a few equations. You can predict future events.
There are several types of regression equations. Some of the more common ones include exponential and simple linear regression (to fit data to an exponential or linear equation). The regression equation most likely to be encountered in elementary statistics takes the form of a linear one.

How to use bar model to find 75% of 500?
To use a bar model to find 75% of 500, you can follow these steps:
Draw a bar to represent the whole quantity, which in this case is 500.Divide the bar into four equal parts, as there are four parts in 100%, since 75% is 3/4 of 100%, each part will represent 25%.Shade in three of the four parts to represent the 75% you are trying to find.Count the number of shaded parts. In this case, you shaded three of the four parts.Use the bar model to calculate the value of the percentage. Since each part represents 25% of the whole quantity, and you shaded three parts, the value of the percentage you are looking for is:3 parts x 25% per part = 75%
Finally, to find the value of 75% of 500, you can multiply 500 by 75% in decimal form (0.75):

Describe function.The mathematics curriculum covers the study of number and their variable as well as our surroundings, architecture, and both actual and hypothetical locations. The link between the amounts of inputs as well as the associated outputs for each is shown graphically by a function. A function is, to put it simply, a group of inputs whose, when combined, result in particular outputs for every input. Each role is assigned a region, locale, or range .
Here,
Given :
f(x) = -x² + 14x³ - 24x⁷ - 10x¹² + 22x⁴ - 18x¹¹ + 4x⁴ +21
To describe the end behavior of the given polynomial function f(x), we only need to consider the term with the highest degree, which is - 10x¹²
Since the degree of the term is even and the coefficient is negative, we know that as x approaches positive or negative infinity, the function will also approach negative infinity.
Therefore, we can say:
As x to -∞, f(x) to - ∞
As x to +∞, f(x) to-∞
So the end behavior of the function
f(x) = -x² + 14x³ - 24x⁷ - 10x¹² + 22x⁴ - 18x¹¹ + 4x⁴ +21
is that the function approaches negative infinity as x approaches positive or negative infinity.

Consider the toss of a pair of dice what is the probability that the total number of dots appearing on top is 7
The probability of rolling a 7 with a pair of dice is 1/6. This is because there are six possible combinations that add up to 7.
Each of these combinations has an equal probability of occurring, so the probability of rolling a 7 is 1/6. (1+6, 2+5, 3+4, 4+3, 5+2, 6+1).
To explain further, when two dice are rolled, there are 36 possible outcomes, each with an equal probability of occurring. Of the 36 outcomes, 6 of them will result in the total number of dots appearing on top being 7. Since 6 out of 36 outcomes result in a 7, the probability of rolling a 7 is 6/36 or 1/6. This means that if two dice are rolled 36 times, there is a 1 in 6 chance that the total number of dots appearing on top will be 7 at least once.

What does CDE describea minor arca major arca semicirclea chord
Answer: CDE can describe a minor arc, a major arc, a semicircle, or a chord, depending on the context in which it is used. Here are the definitions of each of these terms:
A minor arc is an arc of a circle that is smaller than a semicircle. It is named after the two endpoints of the arc. So, CDE would be a minor arc if it is a part of a circle.
A major arc is an arc of a circle that is larger than a semicircle. It is also named after the two endpoints of the arc. So, CDE would be a major arc if it is a part of a circle and spans more than 180 degrees.
A semicircle is an arc of a circle that is exactly half of the circle. It is named after the two endpoints of the diameter that it cuts. So, CDE would be a semicircle if it is a part of a circle and spans exactly 180 degrees.
A chord is a line segment that connects two points on the circle. It is named after the two endpoints of the segment. So, if CDE is a line segment that connects two points on a circle, then it would be a chord.
