The equations of the line that passes though points (2,-1) and (8,4) are
y = 2x/3 - 7/3y = 2x/3 - 28/3How to find the equations of the lineThe linear function written in the slope intercept form form as
y = mx + c
where
m = slope
c = intercept
x = input variables
y = output variables
calculation of slope
The points used for the slope is gotten from the graph as (2,-1) and (8,4)
m = (y₂ - y₁) / (x₂ - x₁)
substituting the values
= (-1 - 4 ) / (2 - 8 )
= -4 / -6
= 2/3
using the point slope formula which is
(2, -1)
(y - y') = m(x - x')
(y - (-1)) = 2/3(x - 2)
y + 1 = 2x/3 - 4/3
y = 2x/3 - 4/3 - 1
y = 2x/3 - 7/3
(8,4)
(y - 4) = 2/3(x - 8)
y - 4 = 2x/3 - 16/3
y = 2x/3 - 16/3 + 4
y = 2x/3 - 28/3

What is balance sheet?A balance sheet is a financial statement that lists the assets and liabilities of a corporation at a certain point in time. It is one of the three primary financial statements—the other two being the income statement and cash flow statement—that are used to assess a company's performance.
The weekly income is of $21,000, while a month is composed by four weeks, hence the monthly income is of:
=4 x $21,000
= $84,000.
Then the percentages of each expenses are applied to find the values, for example, 42% of that is for employee wages, hence:
= 0.42 x 84,000
= $ 35, 280
From the details we get Employee Wages 42% of $35,280.00
Hence, the balance will be of zero and option A is correct.

Here,
x = 0
y = 2
Verify the inequality by changing the values of x and y.
2 > -3 x 0 + 2
2 > 2
It is not correct.
Therefore the point is not to solve the inequality.
B) Point (2,0)
Here
x = 2
y = 0
Verify the inequality by changing the values of x and y.
0 > -3 x 2 + 2
0 > -4

What is function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Four main categories can be used to classify different sorts of functions. One to one function, many to one function, onto function, one to one and into function—all based on the element. A relation between a domain and range is called a function when each value in the domain only has one value in the range.
Here,
function f : {4, 6, 8} → {2, 3} is defined as {(4, 2), (6, 2), (8, 2)},
domain={4,6,8}

Rose chin deposited $900 in a new savings account. The amount for $1.00 compounded daily the account earns after 12 years at 5.25% interest is 1.878. Calculate the compound interest earned after 12 years.
The answer to this Question based on Compound Interest is 1690.2$
What is Compound Interest?
Compound interest is a type of interest that is calculated not only on the initial principal but also on the accumulated interest of previous periods. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal plus previously accumulated interest. It is the concept of earning interest on interest, which causes the total balance to grow at a faster rate than simple interest. Compound interest is often referred to as the eighth wonder of the world, as it is a powerful financial concept that can yield impressive results over a long period.
Initial money deposited = 900$
1$ turns into 1.878$ after 12 years of Compound Interest
hence by basic manipulation we can do like
900$ turns into 900 multiplied by 1.878 which comes out to b 1690$
Hence after 12 years final amount will be 1690$

why does the normal distribution have an importance in statistics of wether or not iut appears in nature
The normal distribution have an importance in statistics of whether or not out appears in nature, because it fits several natural phenomena.
For exa. measurement error, heights, IQ scores, and physical activity measures all follow the normal distribution.
In this question we need to describe why does the normal distribution have an importance in statistics of whether or not out appears in nature.
We know that if we plot the probability distribution and it forms a bell-shaped curve. If the mean, mode, and median of the sample are equal then the variable has normal distribution.
A normal distribution is dependent on two parameters of the data set: mean and the standard deviation of the sample.
This characteristic of the normal distribution makes it extremely simple.
Also, the normal distribution is important because of the Central limit theorem.
It makes math easy - like calculating moments, correlations between variables, and other calculations that are domain specific.

The percentage markdown only affects the price of the baseball bat, not the price of the baseball. Therefore, the price of a baseball will remain the same at $12.
What is meant by the term percentage?One technique to express a number as a fraction of 100 is through the use of percentage. It is typically used to denote a percentage or share of a larger whole, and it is frequently written with the sign "%." For instance, a student who obtains an 80 is referred to as having gotten a "80%" or "80%".
Percentages can be used to compare distinct numbers, to assess change over time, or to establish the proportion of a group or population that fits into a specific category. For example, a survey may state that 60% of respondents said "yes" to a certain question, or that the price of a product has grown by 10% in the last year.

Here we know that: the height and the width are both 2 meters less than the depth, then:W = L - 2H = L - 2 and the volume is 16 cubic meters
Replacing that in the volume equation we will get:16 = L*(L - 2)*(L - 2)It is ratter easy to notice that if we take L = 4, we will get:16 = 4*(4 - 2)*(4 - 2) 16 = 4*(2)*(2)16 = 4*416 = 16 So L = 4 is a solution, then:

Answer: The ratio of red marbles to blue marbles is 3:6. This can be written as a fraction as 3/6, which simplifies to 1/2.
Step-by-step explanation:
To find the ratio of two quantities, you can divide the number of one type of item by the number of another type of item. In this case, the ratio of red marbles to blue marbles is 3 marbles / 6 marbles, which simplifies to 1/2.
It's important to note that a ratio is not the same thing as a percentage or a fraction. A ratio is a comparison of two quantities, while a percentage is a measure of a quantity relative to the total amount and a fraction is a division of one number by another.

The number of hours taken for 8 bunnies to eat the same amount of crops will be 5 hours.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
If 5 bunnies can eat all the crops in a garden in 8 hours. The relation between work and time will be inverse. Then the product of the number of bunnies and the number of hours remains constant.
Let 'x' be the number of hours. Then the equation is given as,

Triangle ABC is a right triangle, with right angle B. Side AC has a length of 13. Side AB has a length of 5. Find the length of side CB.
The magnitude of length BC in the triangle ABC is equivalent to 8.49 units.
What is Pythagoras theorem?Pythagoras theorem states that -
"In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“.
Mathematically, we can write-
[tex]a^2 + b^2 = c^2[/tex]
Given is that ABC is a right triangle, with right angle at B. Side AC has a length of 13 units. Side AB has a length of 5 units.
Using the Pythagoras theorem in the triangle ABC, we get -
AC² = BC² + AB²
BC² = AC² - AB²
BC² = (AC + AB)(AC - AB)
BC² = (13 + 5)(13 - 9)
BC² = 18 x 4
BC² = 72
BC = √(72)
BC = 8.49 units
Therefore, the length of the side BC is equivalent to 8.49 units.
