Residual is the difference between the expected and actual y values, so r I = y I y i. A negative residual indicates that the anticipated value is excessively high, whereas a positive residual indicates that the projected value was excessively low. The goal of a regression line is to reduce the total amount of residuals.
What is Mcq, or salvage value?
When an item reaches the end of its useful life, its salvage value—or potential market value—is estimated. It can also be described as the asset's book value after depreciation has been taken into account.
What does the depreciation formula's residual value mean?
The asset's final worth is its residual value. To obtain the entire amount, it is therefore deducted from the starting value. Consequently, we are given the depreciation figure. This sum is divided by the usable years of the asset using the straight-line depreciation technique.

What is the equation of this line in slope intercept form?
y = mx + b
m = slope
b = y-intercept
The equation of the line in slope intercept form is y = -4x + 1.
What is Slope?Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
Intercept of a line is the point where the line touches with one of the axis.
The general equation of a line in slope intercept form is,
y = mx + d, where m is the slope and d is the y intercept.
y intercept point touches the y axis.
Take any two points from the line.
Let it be (0, 1) and (-1, 5).
Slope = (5 - 1) / (-1 - 0) = 4 / (-1) = -4
m = -4
We have the point (0, 1), where the line touches the Y axis.
y intercept, d = 1.
Equation of the line is,

How to partition line segment?
We are given the line DC with coordinates as;

Keep in mind that a number raised to the power of one is itself. Exponentiation is the process of expressing huge numbers in terms of powers. That is, exponent refers to the number of times a number has been multiplied by itself. For example, 6 is multiplied by itself four times, yielding 6 6 6 6. This is written as 64.

how to find the acute angle of each angle in a triangle if the given angles are in the form of an equation
To find the acute angle of each angle in a triangle if the given angles are in the form of an equation follow the steps in the main answer part
What is the acute angle?To find the acute angles of a triangle given the angles in the form of an equation, you can use the following steps:
Write down the equation for the triangle's angles, typically in the form of "angle A + angle B + angle C = 180 degrees".Use the equation to solve for one of the angles. For example, if the equation is "angle A + angle B + angle C = 180 degrees", you can solve for angle A by subtracting angle B and angle C from 180 degrees.Repeat step 2 for the other angles.Check if the angles are acute or not. An acute angle is an angle that measures less than 90 degrees.If an angle is not acute, use the property of the triangle that the sum of all the angles is 180° and subtract the angle from 180° to get the acute angle.Example: Let's say you are given an equation,
A+B+C = 180°
If
A = 70°
B = 70° then
C = 40°
C is not acute, so subtract it from 180° to get C= 140°
Now you have A = 70° and C = 140° which are acute angles.

Juanita has saved 20% of the money that she needs to buy a new bicycle If she has saved $36 how much money does the bycycle cost
Answer:
$180
Step-by-step explanation:
20*5=100
36*5=180
Answer: the cost of the bicycle is 180$
Step-by-step explanation:
If Juanita has saved 20% of the money she needs to buy a new bicycle and she has saved $36, we can calculate the cost of the bicycle using the following formula:
(100% - 20%) x cost of bicycle = $36
To find the cost of the bicycle, we can divide both sides of the equation by 80% (100% - 20%), like this:
cost of bicycle = $36 / (100% - 20%)
We know that Juanita has saved $36 and the percentage saved is 20% , so the cost of the bicycle is $180

For what value of k do the equation 3x 8y 0 and 6x Ky =- 16 represent coincident lines?
For what value of k = -48 the equation 3x 8y 0 and 6x Ky =- 16 represent coincident lines.
The equation 3x + 8y = 0 and 6x + Ky = -16 represent coincident lines when the two lines are identical, or when their slope and y-intercept are the same.
To find the value of k for which this is true, we can set the two equations equal to each other and solve for k.
3x + 8y = 0
6x + Ky = -16
The equation 3x + 8y = 0 represents the slope-intercept form of a line, where the slope is -3/8 and the y-intercept is 0.
The equation 6x + Ky = -16 represents the general form of a line, where the slope is -K/6 and the y-intercept is -16/K.
To find the value of k for which the two lines are identical, we need to make the slopes and y-intercepts equal.

2. Work out the gradient of the perpendicular bisector: the gradient of the line segment and the perpendicular bisector should multiply to get -1. This means that we can do -1 ÷ -1/3 to work out the gradient which is 3
4. Find the midpoint of the line segment: (-8 + 4) ÷ 2 = -2, and (-2 + -6) ÷ 2 = -4, so the midpoint is (-2, -4)
3. The equation will be in the format y = 3x + c and will go through (-2, -4), so we can substitute those values into the equation to find c:

What are the lines of longitude also called as Class 6?
Longitudes: The vertical lines running north-south, join the two poles. They are called the meridians of longitude. They are spaced farthest apart at the equator and converge at a point at each pole.
Horizontal lines called latitudes are used to measure distances north or south of the equator. Vertical lines known as longitudes are used to determine the west or east of the meridian in Greenwich, England. Latitude and longitude work together to help cartographers, geographers, and others find specific locations on the globe.
What is the uses of latitude?
Any location's distance from the equator may be determined using its latitude, which is based on its degree. We can locate any point on Earth using longitude and latitude. The GPS or Global Positioning System uses these coordinates.

Calculate the geometric mean return of the following data set: (Negative value should be indicated by a minus sign. Round your intermediate calculations to 4 decimal places and final answer to 2 decimal places.)
The geometric mean return of the given data set is 0.02.
The geometric mean return measures the compound rate of return over a period of time. It is calculated by taking the product of all the returns and then taking the nth root of the product, where n is the number of returns.
Formula: GMR = ((1+r1)(1+r2)…(1+rn))^1/n – 1
In this case, the data set is as follows:
r1 = 0.05
r2 = 0.03
r3 = -0.02
Using the formula above, the geometric mean return is calculated as:
GMR = ((1+0.05)(1+0.03)(1-0.02))^1/3 - 1
GMR = ((1.05)(1.03)(0.98))^1/3 - 1
GMR = (1.1394)^1/3 - 1

24. Mr. Karbon is 35 years old and his heart beats on average 62 beats per minute.
How many times has his heart been beating during his life? (assume there are no leap
years)
Mr. Karbon 1,14,05,52,000 times has his heart been beating during his life.
Adults typically have a resting heart rate between 60 and 100 beats per minute. A lower resting heart rate typically indicates improved cardiovascular fitness and more effective cardiac function. A well-trained athlete, for instance, might have a typical resting heart rate that is closer to 40 beats per minute.
Based on your age, you may calculate your maximum heart rate. Subtract your age from 220 to get a ballpark idea of your maximal age-related heart rate. For instance, the predicted maximum age-related heart rate for a 50-year-old person would be computed as 220 - 50 years = 170 beats per minute (bpm).

He tax rate a a percent, r, charged on an item can be determined uing the formula StartFraction c Over p EndFraction minu 1 equal r. – 1 = r, where c i the final cot of the item and p i the price of the item before tax. Louie rewrite the equation to olve for the final cot of the item: c = p(1 ). What i the final cot of a $40 item after an 8% tax i applied?
A $40 item will ultimately cost $43.2 when an 8% tax is included.
The formula Lousie used is:
c = p(1 + r)
We will solve this problem with the help of percentages.
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
We are given that the price of the item is $40
r = 8% .
Therefore,
c = 40(1 + 8%)
c = 40 (1 + 8/100)
c = 40 ((100+8)/100)
c = 40 (108/100)
c = 40 * 1.08 = 43.2
Final cost = $43.2
Therefore the final cost of the $40 item after an 8% tax is applied will be $43.2.
