find the point that is 2/4 the way from A to B where A(-2, 5) and B(4, 9)
Pls help
The coordinates of the point that is 2/4 the way from A to B are (1, 7).
What is the Segment Ratio Formula?The coordinates of the point that divides a segment into a fractional component, n (n+m), or an arbitrary ratio, n:m, are given by:
x = [n ⁄ (n+m)] (x₂ - x₁) + x₁ and y = [n ⁄ (n+m)] (y₂ - y₁) + y₁
Given:
For this problem, n = 2 and m = 2 since (2 ⁄ (2+2) = 2 ⁄ 4, ( x,₁ y₁) =(-2, 5) and ( x₂, y₂) = (4, 9)
Where n and m are both positive integers, [n (n+m)] is the required distance ratio from the beginning position, (x₁, y₁) are the coordinates of one endpoint, and (x₂, y₂) are the coordinates of the other endpoint.
x = [n ⁄ (n+m)] (x2 - x1) + x1
= (2/4 ) (4 - (-2)) + (-2)
= (2/4 ) (4 + 2) + (-2)
= (2/4 ) × 6 + (-2)
= 3 - 2 = 1
y = [n ⁄ (n+m)] (y2 - y1) + y1
= (2/4 ) (9 - 5) + 5
= (2/4 ) (4) + 5
= 2 + 5 = 7
Therefore, the coordinates of the point are (1, 7).

By considering the areas of the two rectangles, we have shown that 2x² - 5x - 18 = 0
The value of length AB is 4.5 cm
Calculating Area and lengthFrom the question, we are to show that 2x² - 5x - 18 = 0
From the given information,
The total area of the compound shape ABCDEF is 36 cm²
That is,
Total area = 36 cm² = Area of small rectangle + Area of big rectangle
From the given diagram, we can write that
Area of small rectangle = x(x -4)
Area of small rectangle = x² - 4x
and
Area of big rectangle = (2x + x)(x -2)
Area of big rectangle = 3x(x - 2)
Area of big rectangle = 3x² - 6x
∴ 36 = x² - 4x + 3x² - 6x
36 = 4x² -10x
4x² -10x - 36 = 0
Divide through by 2
2x² - 5x - 18 = 0
Thus, we have shown that 2x² - 5x - 18 = 0
Now, we are to determine the value of length AB
The value of length AB is x cm.
Therefore, we will solve for x
From,
2x² - 5x - 18 = 0
2x² + 4x - 9x - 18 = 0
2x(x + 2) -9(x + 2) = 0
(2x - 9)(x + 2) = 0
2x - 9 = 0 OR x + 2= 0
2x = 9 OR x = -2
x = 9/2 OR x = -2
x = 4.5 OR x = -2
Since x cannot be negative, the value of x is 4.5
Thus,
AB is 4.5 cm

By using Distribution of the sample mean, “It will have less variation”. So option B is correct.
With Large numbers of successive random samples, the mean of the sampling distribution is equal to the mean population (µ). The variability of each sampling distribution decreases in increase of sample size..
so that they become increasingly more Leptokurtic distribution .
As a sample size increases, sample variance (variation between observations) increases but the variance of the standard error decreases.
The mean of the sample means would be equal to μ (approx.), the mean from which the samples were drawn. However, the sample means will depend on the size of the samples, since big samples are more likely to give estimated means that are equal to the true mean of the population(Approx. )

The linear function that contains the point (-4, -3) and is perpendicular to the line 4x + 5y = 15 is given by:
y = 5/4x + 2.
What is a linear function?A linear function, in slope-intercept format, is modeled according to the following rule:
y = mx + b
In which:
The coefficient m is the slope of the function, which is the constant rate of change.The coefficient b is the y-intercept of the function, which is the initial value of the function.When two lines are perpendicular, the multiplication of their slopes is of -1, hence, considering the line is perpendicular to 4x + 5y = 15, we have that:
5y = 15 - 4x
y = 3 - 4/5x
Then:
-4/5m = -1
m = 5/4
Hence the rule is:
y = 5/4x + b
When x = -4, y = -3, hence the intercept b is found replacing these points into the equation as follows:
-3 = 5/4(-4) + b
-3 = -5 + b
b = 2.
Hence the equation is:
y = 5/4x + 2.
Both perpendicular equations are graphed at the end of the answer.

Eli used the place value strategy to add the numbers 4.69 and 7.7.
What is the very first step he should do to add these numbers correctly?
The addition according the place value is 12.39
What is place value?The value of each digit in a number is known as place value. Every digit in a number has a distinct value depending on where it is located. The value of a digit depends on its location in the number, which might result in a number having two comparable digits with distinct values.
Place value refers to how much a digit is worth in relation to where it is in a number, such as the ones, tens, hundreds, and so on. For instance, 5 in 3458 has a place value of 5 tens, or 50. However, 5 thousands, or 5,000, is used to represent the place value of 5 in 5781. Understanding that a digit can have the same value regardless of where it appears in the number is crucial.
Given:
Eli used the place value strategy to add the numbers 4.69 and 7.7.
So, to add using place value strategy we use place value to break the addends into tens and ones.
Now, we add the tens and ones individually to find the whole sum.
So, breaking 4.69

With the annual interest of 1%, the total saving after 5 years is $6060.
Interest:
Interest is the amount for a particular principal amount of money at some rate of interest.
Given,
You earn $100 per month and want to save 10% in a savings account.
Here we have to use the savings calculator to find out how much your total savings would be in 5 years if your account has an annual interest rate of 1%.
Through the given details we have identified that,
Monthly earning = $100
Saving per month = 10%
So, in amount it can be
=> 100 x 10/100 = $10
So, for one year the saving without interest is
=> 10 x 12 = 1200
So, When we add the interest of 1% for the year,
Then the interest amount for one year will be,
=> 1200 x 1/100 = 12
So, the total amount including interest for one year,
=> 1200 + 12 = 1212
So, the savings after 5 years will be,
=> 5 x 1212
=> 6060.
Therefore, the total saving amount after 5 years is $6060.

When lines are perpendicular, the slopes are opposite inverses of each other. So, the perpendicular slope to 2 is -1/2. I would write the answer in the point slope of the line and then change the equation to the stand form
y -2 = -1/2(x -1) Distribute the -1/2
y - 2 = -1/2x + 1/2 Add 1/2 x to both sides

Answer:
m∠R = 72°
Step-by-step explanation:
As ΔPQR and ΔUVW are congruent, m∠R = m∠W.
Equate the expressions for the two angles and solve for x:
⇒ m∠R = m∠W
⇒ 10x - 18 = 8x
⇒ 10x - 18 + 18 = 8x + 18
⇒ 10x = 8x + 18
⇒ 10x - 8x = 8x + 18 - 8x
⇒ 2x = 18
⇒ 2x ÷ 2 = 18 ÷ 2
⇒ x = 9
Substitute the found value of x into the expression for m∠R:
⇒ m∠R = 10x - 18
⇒ m∠R = 10(9) - 18
⇒ m∠R = 90 - 18
⇒ m∠R = 72°
Therefore, m∠R = 72°.
