The density of the unknown metal exists 8.9 g/mL.
What is meant by density?The mass of an object divided by its volume is how dense it is. The gram per cubic centimeter (g/cm³) unit of density is frequently used. How much mass is present in a given area is referred to as density. Try to picture a drawer full of socks. Its density is particular. Consider that when you remove a sock, the drawer's density changes. This is due to the socks' shifting mass while the drawer's remaining constant volume.
The definition of density is the mass of a substance per unit volume. The degree to which matter is packed together is fundamentally measured by density. It is a specific physical quality of a specific object. Greek scientist Archimedes is credited with discovering the density principle.
The density (D) is equal to mass (m) divided by volume (V): D = m/V
To find the mass of the object:
m = 156 g - 105.5 g = 50.5 g
To find the volume of the volume:
V = 30.7 mL - 25 mL = 5.7 mL
The density is:
D = m/V = 50.5 g / 5.7 mL = 8.9 g/mL
Therefore, the density exists 8.9 g/mL.
The complete question is:
A graduated cylinder was filled with water to the 25.0 mL mark and weighed. Its mass was 105.5g. An object made of an unknown metal was placed in the cylinder and completely submerged in the water. The water level rose to 30.7 mL. When reweighed, the cylinder, water and metal object had a total mass of 156.0g. Based on these measurement, what is the density of the unknown metal?

The median is the middle value of a data set, the first quartile (Q1) is the median of the lower half of the data set, while the third quartile is the upper half. The interquartile range (IQR) is the difference between the first and third quartiles.
What is an interquartile range?The interquartile range (IQR) is a measure of variability defined as the difference between a data set's 75th percentile (Q3) and 25th percentile (Q1). It is often referred to as the midspread or the middle 50% of a data set. The interquartile range (IQR) is a measure of the dispersion of the middle 50% of values in a data set that is commonly used in descriptive statistics.
In the given question, the median is the data set's midway value. The data must first be organized in ascending or descending order before the median can be calculated. Because the data set is already in order in this example, the median may be computed simply locating the data set's middle value. The supplied data set's median is 10 minutes.
The first quartile (Q1) is the median of the data set's bottom half. To compute Q1, first organize the data in ascending or descending order. The lower part of the data set has values ranging from 2 to 11. This subset's median time is 6.5 minutes, which is in the top quartile.
The third quartile (Q3) is the median of the data set's upper half. To compute Q3, first organize the data in ascending or descending order. The upper part of the data set has values ranging from 13 to 41. This subset's median is 14.5 minutes, which is in the third percentile.
The difference between the first and third quartiles is defined as the interquartile range (IQR). The data must first be organized in ascending or descending order before the IQR can be calculated. The supplied data set's IQR is 14.5 - 6.5 = 8 minutes.
The first quartile minus 1.5 times the interquartile range is the lower limit. The data must first be organized in ascending or descending order before the lower limit can be calculated. The supplied data set has a lower limit of Q1 - 1.5 x IQR = 6.5 - (1.5 x 8) = -5.5 minutes.
The third quartile plus 1.5 times the interquartile range is the top limit. The data must first be organized in ascending or descending order before the upper limit can be calculated. The presented data set has an upper limit of Q3 + 1.5 x IQR = 14.5 + (1.5 x 8) = 23.5 minutes.

What is meant by linear equation? A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables. Ax+By=C is the typical form for linear equations involving two variables. A linear equation in standard form is, for instance, 2x+3y=5. Finding both intercepts of an equation in this format is rather simple (x and y).Let the ages of A and B be x and y years respectively.

How do you find all six trigonometric function of θ if the point (-5,12) is on the terminal side of θ?
The six trigonometric functions of an angle θ in a right triangle are sine (sin θ), cosine (cos θ), tangent (tan θ), cotangent (cot θ), secant (sec θ) and cosecant (csc θ).
To find these functions for a given angle θ, we need to know the length of the sides of a right triangle with angle θ.
Given that the point (-5,12) is on the terminal side of θ, we can apply the Pythagorean Theorem to find the length of the sides of the triangle. The Pythagorean Theorem states that a² + b² = c² where a and b represent the lengths of the sides of the triangle and c is the length of the hypotenuse. Using the point (-5,12), we can solve for c, which is 13.
Therefore, the sides of the triangle have lengths 5, 12, and 13. We can now use these lengths to calculate the trigonometric functions of θ.
sin θ = 12/13
cos θ = 5/13
tan θ = 12/5
cot θ = 5/12
sec θ = 13/5
csc θ = 13/12
Therefore, the six trigonometric functions of θ are sin θ = 12/13, cos θ = 5/13, tan θ = 12/5, cot θ = 5/12, sec θ = 13/5 and csc θ = 13/12.

y = 1 to 3
The radius of each cylinder will be r=y and the height will be (greater minus lesser, i.e. right minus left).
h = 2 - (1 + (y-2)²)
h = 1 - y² + 4y -4
h = - y² + 4y - 3
Volume = [tex]\int\limits^a_b {2πrh} \, dy[/tex]
= 2π∫₁³ y.( - y² + 4y - 3)dy
= 16π/3
Hence, the volume of the solid obtained by rotating the region bounded by the given curves about the x-axis is 16π/3.

 solve the following equation for g:
m+n^2 = g5M
The solution of the equation for g is (m+n^2)/5M. The solution has been obtained by solving the given equation for g.
What is an equation?
A mathematical definition of an equation is a claim that two expressions are equal and joined by the equals sign "=". The two expressions need not be completely of variables i.e. one expression may contain variable and the other may not contain a variable.
We are given g: m+n^2 = g.5M
⇒m+n^2 = g.5M
⇒m+n^2 = 5gM
⇒5gM = m+n^2
⇒5gM/5M = (m+n^2)/5M .... (Dividing both sides by 5M)
⇒g = (m+n^2)/5M
Hence, the solution of the equation for g is (m+n^2)/5M.

Anya gathered a random sample of bags of potato chips from a popular company. She calculated data on different variables. For one data that she collected, she constructed a circle graph. Which of the following variables did she use?
Price of bag of potato chips
Number of chips in the bag of potato chips
Weight of bag of potato chips
Flavor of the bag will be shown in circle graph because different bag has different flavor
given that
A chord diagram's intersection graph is referred to as a circle graph in graph theory. In other words, it is an undirected graph whose vertices can be connected by a finite system of circular chords, with two vertices being connected only when their corresponding chords cross.
Anya selected a smattering of bags of potato chips from a well-known manufacturer.
She computed data on several variables.
She created a circle graph for one of the data sets she collected.
We now need to determine which variables she used in the circle graph.
The average of all the potatoes will be displayed in a circular graph.
Because the price of a bag of potatoes is the same for everyone, it won't be displayed.
Since there are the same number of chips in every bag, the number of chips in the potato chip bag will not be displayed.
Since the weight of each bag of potato chips is the same, it will not be displayed.
Since each bag has a distinct flavor, the circle graph will display the bag's flavor.

n³ +2n is divisible by 3 is the statement that we want to prove and A) n³+2n=k³ +2k is divisible by 3 is not a valid statement.
Option (A) is correct.
What is mathematical induction?
Mathematical induction is a method of proof used to establish the truth of a statement for all positive integers (or natural numbers).
In step 3 of a proof by mathematical induction, you are trying to show that if the statement is true for some positive integer k, then it is also true for the next positive integer (k+1). So you would be trying to show that:
B) (k+1)³ +2(k+1) is divisible by 3
is true, assuming that
D) k³+2k is divisible by 3
is true.
In other words, you are trying to show that if the statement is true for some positive integer k, then it is also true for the next positive integer (k+1).
Hence, n³ +2n is divisible by 3 is the statement that we want to prove and A) n³+2n=k³ +2k is divisible by 3 is not a valid statement.
