Adding together all the residuals from a regression plot will always sum to 0. True False.
The given statement "Adding together all the residuals from a regression plot will always sum to 0" is False. A residual is defined as the difference between the observed value and the predicted value for each data point in a regression plot. The sum of residuals is not always equal to 0.
In a linear regression plot, the predicted values for each data point are calculated using the line of best fit. The residual for each data point is calculated as the difference between the observed value and the predicted value. The residuals are a measure of how well the line of best fit predicts the observed data. Ideally, the residuals should be randomly distributed around 0.
The sum of the residuals will be 0 only if the line of best fit perfectly predicts the observed data. However, this is not always the case. In fact, a good regression plot will have some residuals that are positive and some that are negative, resulting in a sum that is not equal to 0. This is because the line of best fit is only an estimate of the relationship between the variables being studied and will never perfectly predict the observed data.
Therefore, the statement "Adding together all the residuals from a regression plot will always sum to 0" is False. The sum of residuals may be close to 0 in some cases, but it will not always be exactly equal to 0.

Find the apothem and the area
The answer of the given question based on the pentagon is , the apothem of the pentagon is approximately 13.76 meters, and the area of the pentagon is approximately 688 meter².
What is Apothem?An apothem is line segment that is drawn from center of regular polygon to midpoint of one of its sides. The apothem is always perpendicular to the side it intersects and is typically used to calculate the area of the polygon. In a regular polygon, all sides are congruent and all interior angles are also congruent. The apothem, therefore, is the radius of the inscribed circle of the polygon.
Apothem can be found using the formula:
a = (s/2) * (1/tan(π/n))
where s is the length of one side of the pentagon, and n is the number of sides (in this case, n=5 for a pentagon).
Plugging in s=20 and n=5, we get:
a = (20/2) * (1/tan(π/5))
a ≈ 13.76m
So the apothem of the pentagon is approximately 13.76 meters.
To find the area of the pentagon, we can divide it into five congruent triangles, each with base equal to the length of one side (20m) and height equal to the apothem (13.76m). The area of each triangle is:
(1/2) * base * height = (1/2) * 20m * 13.76m ≈ 137.6m²
So the area of the pentagon is the sum of the areas of the five triangles:
A = 5 * (1/2) * base * height = 5 * 137.6m² ≈ 688m²
Therefore, the apothem of the pentagon is approximately 13.76 meters, and the area of the pentagon is approximately 688 meter².

If YZ is the requested side and XZ is the given side, which ratio amongst sin 35,3° or cos 35,5° will be used to calculate YZ
The answer of the given question based on the trigonometry is , to calculate YZ, we should use the cosine function with the angle 35.5°.
What is Sine function?The sine function is a mathematical function that relates the ratios of the lengths of two sides of a right triangle with the measure of one of its non-right angles. Specifically, the sine of an angle in a right triangle is defined as the ratio of the length of the side opposite to the angle to the length of the hypotenuse.
To use trigonometry to calculate YZ, we need to find a trigonometric ratio that involves the given side XZ and the angle opposite the requested side, which is angle YXZ. We don't have the measure of this angle, but we know that it is supplementary to the given angle 35.5°, so it must measure:
180° - 35.5° = 144.5°
We can use this angle and the given side XZ to find the length of YZ using the sine or cosine function.
In this case, the length of the opposite side is YZ, the length of the hypotenuse is XZ, and the measure of the angle is 144.5°. So we can write:
sin(144.5°) = YZ / XZ
Solving for YZ, we get:
YZ = XZ * sin(144.5°)
On the other hand, the cosine function , this case, the length of the adjacent side is YZ, the length of the hypotenuse is XZ, and the measure of the angle is 35.5°. So we can write:
cos(35.5°) = YZ / XZ
Solving for YZ, we get:
YZ = XZ * cos(35.5°)
Therefore, to calculate YZ, we should use the cosine function with the angle 35.5°.

a die is continuously rolled 104 104 times. what is the probability that the total sum of all rolls does not exceed 375 375 ?
The probability that the total sum of all rolls does not exceed 375 is approximately 0.7165
Assuming the die is a fair six-sided die, the possible outcomes for each roll are numbers 1 through 6, each with a probability of 1/6.
Let X be the total sum of all rolls. Then X follows a discrete uniform distribution with parameters n = 104 (number of rolls) and a = 1 (minimum value of each roll). The expected value of X is:
E(X) = n × (a + b) / 2 = 104 × (1 + 6) / 2 = 365
The variance of X is
Var(X) = n × (b - a + 1)^2 / 12 = 104 × 6^2 / 12 = 312
The standard deviation of X is
SD(X) = sqrt(Var(X)) = sqrt(312) = 17.67
To calculate the probability that the total sum of all rolls does not exceed 375, we need to calculate the cumulative distribution function (CDF) of X and evaluate it at 375
P(X <= 375) = F(375)
where F(x) = P(X <= x) is the CDF of X.
Using the normal approximation to the binomial distribution, we can approximate X as a normal distribution with mean E(X) = 365 and standard deviation SD(X) = 17.67
Z = (X - E(X)) / SD(X)
Z follows a standard normal distribution with mean 0 and standard deviation 1.
P(X <= 375) = P(Z <= (375 - E(X)) / SD(X))
= P(Z <= (375 - 365) / 17.67)
= P(Z <= 0.566)
Using a standard normal distribution table or a calculator, we can find that P(Z <= 0.566) is approximately 0.7165.

if one flag pole is y feet tall and casts a shadow x feet long, then how tall is another nearby flag pole that casts a shadow p feet long at the same time of day?
If one flag pole is y feet tall and casts a shadow x feet long, and another nearby flag pole casts a shadow p feet long at the same time of day, we can use similar triangles to determine the shadow of the second flag pole.
In this scenario, the two flag poles and the ground form two similar right triangles. The height of the first flag pole (y) corresponds to one leg of the first triangle, and the length of its shadow (x) corresponds to the other leg.
Similarly, the height of the second flag pole (h) corresponds to one leg of the second triangle, and the length of its shadow (p) corresponds to the other leg.
Therefore, the height of the second flag pole is equal to the product of the height of the first flag pole and the length of the shadow of the second flag pole, divided by the length of the shadow of the first flag pole.

a small cube with side length 6y is placed inside a larger cube with side length . what is the difference in the volume of the cubes?
The difference in the volume of a small cube with a side length 6y is placed inside a larger cube with a side length is 5616y³
To find: the difference in the volume of the cubes.
Let the length of the larger cube be x.
So, the volume of the smaller cube is (6y)³ and the volume of the larger cube is x³.
As the smaller cube is placed inside the larger cube, it means that its side length is equal to the side length of the smaller cube plus twice the side length of the smaller cube.
So, x = 6y + 2(6y) = 18y.
The volume of the smaller cube = (6y)³ = 216y³
The volume of the larger cube = x³ = (18y)³ = 5832y³.
So, the difference in volume
= Volume of the larger cube - Volume of the smaller cube
= 5832y³ - 216y³
= 5616y³.
Therefore, the difference in the volume of the cubes is 5616y³.

Using the volume formula it is obtained that the least number of bags Martin should buy is Option C: 13.
What is volume?
Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
First, we need to convert the height of the cylinder from inches to feet -
6 inches = 6/12 feet = 0.5 feet
The volume of the cylinder can be calculated as -
V = πr²h
where r is the radius and h is the height.
Substituting the given values, we get -
V = 3.14 x 2² x 0.5
V = 6.28 cubic feet
Since each bag contains 0.5 cubic feet of sand, we can find the number of bags needed by dividing the total volume by the volume of each bag -
n = V / 0.5
n = 6.28 / 0.5
n = 12.56
Since we can't buy a fractional number of bags, we must round up to the nearest whole number.
Therefore, Martin needs to buy at least 13 bags of sand.

What are trigonometric functions?Trigonometric functions are mathematical functions that are related to the angles of a right triangle to the lengths of its sides. They are widely used in mathematics, physics, engineering, and other fields to describe and analyze periodic phenomena and wave motion.
To find g(x) and f(x) from h(x) = [tex]\rm (sin\ x)^{3}[/tex], we need to use inverse operations to isolate sin x.
First, we can take the cube root of both sides of the equation to undo the cube power:
[tex]\rm h(x)^{1/3}[/tex] = (sin x)
Now we can substitute this expression for sin x in the standard functions g(x) and f(x):
g(x) = cos x
f(x) = [tex]\rm h(x)^{1/3}[/tex] = [tex]\rm (sin\ x)^{3}[/tex]
