What is a reflection?There are two ways of translation.
Along x-axis:
(x, y) – (x, -y)
Along y-axis:
(x, y) - (-x, y)
We have,
ΔABC:
Coordinates:
A = (2, 3)
B = (5, 1)
C = (4, 4)
Reflection across y = 5.
So,
A = (2, 5)
There are two units between y = 5 and y = 3.
We add 2 units with the y-coordinate of A = (2, 5)
5 - 3 = 2
So,
A = (2, 5 + 2)
A = (2, 7)
Similarly,
5 - 1 = 4
B = (5, 5 + 4) = (5. 9)
5 - 4 = 1
C = (4, 5 + 1) = (4. 6)
Translation of 1 unit down.
A = (2 - 1, 7) = (1, 7)
B = (5 - 1, 9) = (4, 9)
C = (4 - 1, 6) = (3, 6)
Thus,
The coordinates of ΔA'B'C' are (1, 7), (4, 9), and (3, 6).

What is the margin of error?Your results will vary from the actual population value by how many percentage points, as indicated by the margin of error. A 95% confidence interval with a 4% margin of error, for instance, indicates that your statistic will, 95% of the time, be within 4% of the true population figure.
Given:
The margin of error, ME = 0.04,
The value of p = 0.12,
The confidence level = 99%,
Calculate the minimum sample size as shown below,

What is probability ?Probability refers to possibility.
A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution.
Knowing the total number of outcomes is necessary before we can calculate the likelihood that a specific event will occur.
According to our question-
The sample variance's variance (SD) is still very large. The range is from 20 to 30%.
Because we are utilizing estimated population variance rather than the genuine population variance, which has some degree of uncertainty, the e t distribution has a longer tail when degrees of freedom are limited. Given that the estimated population variance is nearer to the actual population variance when sample size = 30, the t distribution will be closer to the z distribution.

What is the y intercept of the equation y - 6 = -2(x + 5)
Answer:
Step-by-step explanation:
To find the y-intercept of the equation y - 6 = -2(x + 5), we can set x equal to 0, since the y-intercept is the point where the graph of the equation crosses the y-axis.
Substituting 0 for x, we get:
y - 6 = -2(0 + 5)
y - 6 = -2(5)
y - 6 = -10
y = -4
Therefore, the y-intercept of the equation y - 6 = -2(x + 5) is (0, -4). This means that the graph of the equation crosses the y-axis at the point (0, -4).

A piece of cardboard is 5 centimeters longer than it is tall. The area of the piece of cardboard is 66 square centimeters. How many centimeters long is the piece of cardboard?
Answer:
12.244 cm long
Step-by-step explanation:
The area of a rectangle is equal to its height times its width, so if the piece of cardboard has an area of 66 square centimeters and is 5 centimeters longer than it is tall, we can write the following equation to represent the dimensions of the piece of cardboard:
height * (height + 5) = 66
To solve this equation, we can first divide both sides of the equation by the height of the piece of cardboard to get:
height + 5 = 66 / height
We can then subtract 5 from both sides of the equation to get:
height = 66 / height - 5
We can then multiply both sides of the equation by the height to get:
height^2 = 66 - 5 * height
We can then use the quadratic formula to solve for the height of the piece of cardboard:
height = (-5 +/- sqrt(5^2 - 4 * 1 * -66)) / (2 * 1)
The value of the square root in the quadratic formula must be positive, so we take the positive value for the height:
height = (-5 + sqrt(5^2 + 4 * 1 * 66)) / (2 * 1)
This simplifies to:
height = (5 + sqrt(61)) / 2
The height of the piece of cardboard is approximately 7.244 centimeters. Since the piece of cardboard is 5 centimeters longer than it is tall, it must be 5 + 7.244 = 12.244 centimeters long.
Therefore, the piece of cardboard is approximately 12.244 centimeters long.

Answer:

Step-by-step explanation:
given Δ ABD is isosceles with AB = AD then base angles are congruent, so
∠ ADB = ∠ ABD = 72°
then
∠ BAD = 180° - (72 + 72)° = 180° - 144° = 36° ( sum of angles in a triangle )
given Δ ABC is isosceles , then
∠ BCD = ∠ BAD = 36°
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ ADB is an exterior angle of Δ BCD , then
∠ BCD + ∠ DBC = ∠ ADB
36° + ∠ DBC = 72° ( subtract 36° from both sides )
∠ DBC = 36°
So ∠ BCD = ∠ DBC = 36°
Thus the base angles of Δ BCD are congruent , then
Δ BCD is isosceles with BD = CD

We need to use the concept of Relative Abundance. Relative Abundance of A,B and C are 14.28,57.14 and 28.57% respectively.
What is Relative Abundance?The percentage of an organism of a specific sort in relation to the overall number of organisms in the area is known as relative abundance. Relative species abundances frequently follow particular patterns, some of the most well-known and extensively researched patterns in macroecology. Over a large variety of biological ecosystems, relative species abundances exhibit relatively similar patterns. Most species are rare (represented by a single individual in a community sample), while only a small number of species are prolific, according to a histogram of the number of species represented by 1, 2, 3,..., n individuals.
(M1)(x) + (M2)(1-x) = M(E) is the formula for Relative Abundance.
CalculationA weighs 12g, B weighs 16g and C weighs 24g.
A customer buys 1 apple A, 3 apples B and 1 apple
So assume A,B and C as different isotopes of apples.
Relative Abundance of A=12/84 ×100⇒14.28%
Relative Abundance of B=48/84 ×100⇒57.14%
Relative Abundance of C=24/84 ×100⇒28.57%

givena triangle with side ollenghts of 5 and 8 which iniquality describes all possible lenghs of the thhird side
given a triangle with side of lengths of 5 and 8 then c^2 =89 inequality describes all possible lengths of the third side
In the right triangle of sides a, b, and c
a^2 + b^2 = c^2
Since a = 5 and c = 8
Substitute them in the given rule
we get
25+64= c^2
89= c^2
Take a square root for both sides
c= sqrt 89

Can someone please explain what formula to use when solving this problem ?
Answer:
Step-by-step explanation:
10 months=10/12=5/6 years.
Amount=Principal+ Interest
A=P+I
A=P+P×r×t
A=P(1+rt)
18500=P(1+4%×5/6)
18500=P(1+20/600)
18500=P(1+1/30)
18500=P(31/30)
P=18500×30/31≈17903.2258≈17903.23

Dependent variable: A dependent variable is a variable that changes or is impacted by other factors. independent variable: An independent variable is a variable that does not change or are impacted by other factors.
What is Regression?Regression is a method for figuring out the relationship between two or more variables. In other words, it is determined by how the predictor variable changes and how the dependent variable changes. Additionally, when more than one independent variable is included in a regression analysis, the change in the dependent is examined while maintaining the same values for the other independent variables.
The best fit for the data is linear regression if the data set is bivariate. The data with two variables are best represented by the straight line known as the least squares regression line.
When the explanatory variable has a value of zero, the response variable's projected value is shown by the regression line's y-intercept (though be wary of extrapolation in interpreting the intercept or other values outside the original data range).
The best fit for the data is linear regression if the data set is bivariate. The data with two variables are best represented by the straight line known as the least squares regression line. The line's equation is provided by,
y = a+bx
where,
a—Intercept
b—Regression coefficient
y—Predicted value of the dependent variable
x —Independent or predictor variable
