The coordinates M along the directed line segment is (-12, -2)
How to find the coordinates of the point along the directed line segment?The points are given as:
K = (-16, 10)
L = (-9, -11)
The ratio on the segment can be represented as;
KM : LM, m : n = 4 : 3
So, we have the coordinates of the point M that lies along the directed line segment to be
M = 1/(m + n) * (mx₂ + nx₁, my₂ + ny₁)
So, we have:
M = 1/(4 + 3) * (4 * -9 + 3 * -16, 4 * -11 + 3 * 10)
Evaluate
M = 1/7 * (-84, -14)
Evaluate
M = (-12, -2)
Hence, the coordinates of the point M is (-12, -2)

What miles per gallon did the car get after 280 miles using 8 gallons of gas?
Answer: 35 miles
Step-by-step explanation:
First we divide 280 by 8 to get the answer per gallon. 280 / 8 = 35, therefore each gallon equals 35 miles.
How do I solve the following equation?
keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above
[tex]y=\stackrel{\stackrel{m}{\downarrow }}{-\cfrac{1}{3}}x+7\qquad \impliedby \qquad \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]
so we're really looking for the equation of a line whose slope is -1/3 and that it passes through (-2 , 5.5)
[tex](\stackrel{x_1}{-2}~,~\stackrel{y_1}{5.5})\hspace{10em} \stackrel{slope}{m} ~=~ - \cfrac{1}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{5.5}=\stackrel{m}{- \cfrac{1}{3}}(x-\stackrel{x_1}{(-2)}) \implies y -5.5= -\cfrac{1}{3} (x +2)[/tex]
[tex]y-5.5=-\cfrac{1}{3}x-\cfrac{2}{3}\implies y=-\cfrac{1}{3}x-\cfrac{2}{3}+5.5\implies y=-\cfrac{1}{3}x-\cfrac{2}{3}+\cfrac{55}{10} \\\\\\ y=-\cfrac{1}{3}x-\cfrac{2}{3}+\cfrac{11}{2}\implies {\Large \begin{array}{llll} y=-\cfrac{1}{3}x+\cfrac{29}{6} \end{array}}[/tex]

Determine the slope-intercept form of the equation of the line parallel to y = -4/3x + 11 that passes through the point (–6, 2). y = x +
The equation of the line in slope-intercept form is y = -4x/3-6 when the line is parallel to y = -4x/3+11.
According to the question,
We have the following information:
The line is parallel to y = -4/3x + 11 and passes through the point (–6, 2).
Now, we know that the following formula is used to find the equation of the line:
y-y' = m(x-x')
In this case, m is the slope of the line.
m = -4/3
We have the following values:
x' = -6 and y' = 2
Now, we have the following expression:
(y-2) = -4/3(x+6)
y-2 = -4x/3-8
Adding 2 to both sides of the equation:
y = -4x/3-8+2
y = -4x/3-6
Hence, the equation of the line in slope-intercept form is y = -4x/3-6 when the line is parallel to y = -4x/3+11.

A circular plot with 1000 ft diameter is watered by a spray irrigation system. To the
nearest square foot, find the area that is watered as the sprinkler rotates 90°.
The area that is watered as the sprinkler rotates 90° is 196,250.
What is the area of the circular plot?
The space a circle takes up in a two-dimensional plane is known as the area of the circle. Alternately, the area of the circle is the area included inside the circumference or perimeter of the circle. A = πr², where r is the circle's radius, is the formula for calculating a circle's surface area.
Here, we have
Diameter = 1000ft
Radius = 500
Then, we apply the area of a circle and get
= (90/360)× π×(500)²
= 62,500 × π
= 196,250
Hence, the area that is watered as the sprinkler rotates 90° is 196,250.

to ensure that all treatment groups are roughly equivalent regarding the variability within the experimental units
4) Intro
English
The correct answer is Option A.
Randomization important because it is used to ensure all treatment groups receive experimental units .
What is randomization ?Randomization is mostly used in experiments to establish a cause and effect link and regulate the underlying variable. Also, the evidence is strengthened by randomizing an experiment. Good. To ensure that the outcomes are accurate, randomization is mostly used in experiments.Every experimental unit has the same chance of receiving any therapy, and treatments are distributed to them entirely at random. -A random number table, computer, program, etc. are used to perform randomization.Fixed allocation randomization and adaptive randomization are the two main categories of randomization techniques. The majority of trials employ fixed randomization, in which subjects are assigned to the intervention or comparator with a probability that remains constant over the course of the investigation.

Samuel is taking a multiple choice test with a total of 100 points available. Each question is worth exactly 5 points. What would be Samuel's test score (out of 100) if he got 9 questions wrong? What would be his score if he got xx questions wrong?
If Samuel answers 9 questions wrong, his score will be 55 points, and if he answers x questions wrong his score is:
f(x) = 100 - x*5
What will be Samuel's score if he got 9 questions wrong?
We know that there are 100 points available, and each question gives 5 points, then the number of questions is given by the quotient:
100/5 = 20
There are 20 questions.
So, if you answer 9 wrong, then you answer:
20 - 9 = 11 correctly
Then your score is:
11*5 = 55
Your score will be 55 points.
And again, each answer gives 5 points, so if you answer x questions wrong your score will be the linear equation:
f(x) = (20 - x)*5
f(x) = 100 - x*5
Where x is an integer between 0 and 20.

Step-by-step explanation:
an exponential function can be expressed in the form

to find a and b use points that lie on the graph
using (0, 8 ) , then
8 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ] , then a = 8
y = 8[tex]b^{x}[/tex]

John is in charge of feeding the pigs and cows on the farm. The cow's food costs twice as much as the pig's food. There are 46 cows and 22 pigs on the farm. John has an $860 budget for food a month. How much can John spend on food for each cow per month?
The amount John will spend on food for each cow per month is approximately 15.08 dollars
How to find the how much each cow feed per month?John is in charge of feeding the pigs and cows on the farm.
The cow's food costs twice as much as the pig's food.
Let
x = cost of pigs food
y = cost cow's food
Hence,
y = 2x
There are 46 cows and 22 pigs on the farm. John has an $860 budget for food a month.
46y + 22x = 860
Therefore, let's combine the system of equation.
y = 2x
46y + 22x = 860
46(2x) + 22x = 860
92x + 22x = 860
114x = 860
x = 860 / 114
x = 7.5 dollars
y = 2(7.54) = 15.08 dollars
Therefore, the cost of food for each cow is 15.08 dollars

What is the expected change in the dividend of a 6% preferred stock if the required rate of return drops instantly from 8% to 6%?
The expected change in the dividend of a 6% preferred stock is $75.
Given that, the required rate of return drops instantly from 8% to 6%.
What is the return?A return, also known as a financial return, in its simplest terms, is the money made or lost on an investment over some period of time.
The value of preferred stock = $100
Annual dividend = 100 × 6% = $6
Price of preferred stock when required return is 8% = Annual dividend / Required rate of return
= 6/8%
= 6 ×100/8
= $75
