The tatment which describe best a bar graph is data are presented with bars that are proportional in height to the measured value.
Let us know more about a bar graph .
The pictorial representation of grouped data, in the form of vertical or horizontal rectangular bars, where the lengths of the bars are equivalent to the measure of data, are known as bar graphs or bar charts.
The bars drawn are of uniform width, and the variable quantity is represented on one of the axes. Also, the measure of the variable is depicted on the other axes. The heights or the lengths of the bars denote the value of the variable, and these graphs are also used to compare certain quantities. The frequency distribution tables can be easily represented using bar charts which simplify the calculations and understanding of data.
The three major attributes of bar graphs are:
1) The bar graph helps to compare the different sets of data among different groups easily.
2) It shows the relationship using two axes, in which the categories are on one axis and the discrete values are on the other axis.
3) The graph shows the major changes in data over time.The bar graphs can be vertical or horizontal. The primary feature of any bar graph is its length or height. If the length of the bar graph is more, then the values are greater than any given data.
Bar graph normally show categorical and numeric variables arranged in class intervals. They consist of an axis and a series of labelled horizontal or vertical bars. The bars represent frequencies of distinctive values of a variable or commonly the distinct values themselves. The number of values on the x-axis of a bar graph or the y-axis of a column graph is called the scale.
The types of bar charts are as follows:
Vertical bar chart
Horizontal bar chart
Even though the graph can be plotted using horizontally or vertically, the most usual type of bar graph used is the vertical bar graph. The orientation of the x-axis and y-axis are changed depending on the type of vertical and horizontal bar chart. Apart from the vertical and horizontal bar graph, the two different types of bar charts are:

Answer:
C) To know whether 2 triangles are similar, it is enough to know the measure of 2 angles in each triangle.
Step-by-step explanation:
Two triangles are said to be similar if:
corresponding angles are the same size, andcorresponding sides are in the same ratio.As there are three interior angles in a triangle, and the sum of the interior angles is always 180°, we need to know the measure of at least 2 angles in each triangle to determine if they are similar. The known angles don't have to be corresponding angles, as we can calculate the third angle and then compare all three angles to determine if the triangles are similar.
With regards to the sides of a triangle, it is not enough to know the measure of 2 sides to determine if they are similar. We would need to know at least one interior angle in this case.
True or False: In testing hypotheses, the researcher initially assumes that the alternative hypothesis is true and uses the sample data to reject it.
In testing hypotheses, the researcher initially assumes that the alternative hypothesis is true and uses the sample data to reject it. This statement is False.
Hypothesis testing is an inferential procedure that uses data from a sample to draw a general conclusion about a population. It is a formal approach and a statistical method that uses sample data to evaluate hypotheses about a population. When interpreting a research question and statistical results, a natural question arises as to whether the finding could have occurred by chance. Hypothesis testing is a statistical procedure for testing whether chance (random events) is a reasonable explanation of an experimental finding.
In hypothesis testing, we will always set up a particular hypothesis that we want to demonstrate to be true. We then use probability to determine the likelihood of our hypothesis is correct. If it appears our original hypothesis was wrong, we reject it and accept the alternative hypothesis. The alternative hypothesis is usually the opposite of our original hypothesis. In Fisher’s case, his original hypothesis was that the lady was guessing. His alternative hypothesis was the lady was not guessing.
Generally speaking, the hypotheses that business researchers want to prove are stated in the alternative hypothesis.
Thus, the statement 'In testing hypotheses, the researcher initially assumes that the alternative hypothesis is true and uses the sample data to reject it' is False.

The graph below shows a linear relationship between x and y. Assume that both the x-axis and the y-axis have the same scale. Determine the value of the constant rate of change of y with respect to x (This is a numerical value.) Write a formula that expresses change in y in terms of change in x. Suppose that y = 1.5 when x=1 Write a formula that expresses y in terms of x.
The value of the constant rate of change of y with respect to x is 20.
A formula that expresses change in y in terms of change in x is y = kx.
Suppose that y = 1.5 when x = 1, a formula that expresses y in terms of x is k = 1.5.
How to determine the value of the constant rate of change?In Geometry, the rate of change of any straight line simply refers to its gradient or slope and it can be calculated by using this mathematical expression;
Rate of change (slope), m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Rate of change (slope), m = (y₂ - y₁)/(x₂ - x₁)
Assuming that both the x-axis and the y-axis have a scale of 1:20, the constant rate of change is given by:
Constant rate of change = 20/1 = 20.
When y = 1.5 and x = 1, a formula that expresses y in terms of x is given by:
y = kx
k = y/x
k = 1.5/1
k = 1.5.

Sketch an angle θ in standard position such that θ has the least possible positive measure, and the point (0,-2) is on the terminal side of θ. Then find the values of the six trignometric functions for the angle. Rationalize deniminators is applicable. Do not use a calculator.
Find sin θ, cos θ, tan θ, csc θ, sec θ, and cot θ.
If it is undefined, say undefined.
The values of the six trignometric functions for the angle are
Sinθ = Sin(3π/2) = -1Cosθ = Cos(3π/2) = 0tanθ = tan(3π/2) = undefined Cotθ = Cot(3π/2) = 0Cscθ = Csc(3π/2) = 1Secθ = Sec(3π/2) = undefinedThe above sketch an angle θ in standard position such that θ has the least possible positive measure, and the point (0,-2) is on the terminal side of θ. We have to determine the value of six
triganomertric functions at angle θ. As we see at terminal side point (0,-2) the value of angle θ = 3π/2. The six trigonometric functions are sine, cosine , secant , cosecant , tangent , cotangent .
Now, Sinθ = Sin(3π/2) = Sin( π + π/2)= Sin ( 180° + π/2) = - sin(π/2) ( since, 180° + θ represents 3rd quadrant where sinθ is negative)
=> Sinθ = - 1
Cosθ = Cos(3π/2) = Cos( π + π/2)= Cos( 180° + π/2) = - Cos(π/2) ( since, 180° + θ represents 3rd quadrant where cosθ is negative)
=> Cosθ = Cos(π/2) = 0
tanθ = tan (3π/2) = tan( π + π/2)= tan( 180° + π/2) = - tan(π/2) ( since, 180° + θ represents 3rd quadrant where tanθ is positive)
=> tanθ = - sin(π/2)/cos(π/2) = 1/0
= undefined
Cscθ = Csc(3π/2) = Csc( π + π/2)= Csc( 180° + π/2) = - Csc(π/2) ( since, 180° + θ represents 3rd quadrant where cscθ is negative)
=> Cscθ = - Csc (π/2) = - 1/sin(π/2) = 1
Secθ = Sec(3π/2) = Se( π + π/2)= Sec( 180° + π/2) = - Sec(π/2) ( since, 180° + θ represents 3rd quadrant where secθ is negative)
=> Secθ = -Sec(π/2) = -1/cos(π/2) = - 1/0
= undefined
Cotθ = Cot(3π/2) = Cot( π + π/2)= Cot( 180° + π/2) = Cot(π/2) ( since, 180° + θ represents 3rd quadrant where cotθ is positive)
=> Cotθ = cot(π/2) = Cos(π/2)/sin(π/2) = 0
Hence, we determined all required triganomertric functions value for θ=3π/2.

The six trignometric functions' values for the angle are
Tan = tan(3/2) = undefined, Sin = Sin(3/2) = -1, Cos = Cos(3/2) = 0, and vice versa.
Cot = Cot(3/2), Csc = Csc(3/2), and Sec = Sec(3/2), respectively.
The above drawing shows an angle in standard position with the point (0,-2) on the angle's terminal side and the smallest positive measure achievable. We must calculate the value of six.
Triganomertric operates at an angle. As can be seen, the angle's value is 3/2 at the terminal side point (0,-2). In trigonometry, there are six different functions: sine, cosine, secant, cosecant, tangent, and cotangent.
At this point, Sin = Sin(3/2) = Sin( + /2)
= Sin ( 180° + π/2) Since 180° + denotes the third quadrant, where sin is negative, the expression is equal to - sin(/2).
=> Sinθ = - 1
Cos is equal to Cos(3/2) = Cos(+/2)
because 180 degrees, = Cos(180° + /2) = - Cos(/2)
Since 180° + denotes the third quadrant, where cos is negative, the equation is Cos(180° + /2) = - Cos(/2).
Hence, Cos = Cos(/2) = 0.
Tan is equal to Tan (3/2) = Tan (+/2)
= tan( 180° + π/2) Since 180° + denotes the third quadrant, where tan is positive, the expression is = - tan(/2).
Consequently, tan = - sin(/2)/cos(/2) = 1/0
not defined
Csc is equal to Csc(3/2) = Csc(+/2)
Since 180° + represents the third quadrant, where csc is negative, Csc(180° + /2) = - Csc(/2)
=> 1/sin(/2) = 1 = Csc = - Csc (/2)
Se( + /2) = Se( = Sec(3/2)
Since 180° + represents the third quadrant, where sec is negative, sec(180° + /2) = - Sec(/2)
The formula is: Sec = -Sec(/2) = -1/cos(/2) = -1/0.
not defined
Cot = Cot(3/2), which equals Cot(+/2)
Since 180° + denotes the third quadrant, where cot is positive, the equation is Cot(180° + /2) = Cot(/2).
Consequently, Cot = Cot(2/2) = Cos(2/2)/sin(2/2) = 0
As a result, we calculated the values for all necessary triganomertric functions for 3/2.

A cylindrical pottery vase has a diameter of 4.3 inches and a height of 11 inches. What is the surface area of the vase? Use the formula SA= B+ Ph, since the vase has a bottom but no top. Use 3.14 for TT and round to the nearest tenth of a square inch.
Answer: To find the surface area of the cylindrical vase, we can use the formula:
SA = B + Ph
Where B is the area of the base (the circular top of the vase), P is the perimeter of the circular top of the vase, and h is the height of the vase.
We know that the diameter of the vase is 4.3 inches and the height of the vase is 11 inches. To find the radius of the base, we can divide the diameter by 2:
r = 4.3 inches / 2 = 2.15 inches
The area of the base is given by πr², so:
B = πr² = π * 2.15² = 14.65 square inches
To find the perimeter of the circular top we can use 2πr:
P = 2πr = 2 * 3.14 * 2.15 = 13.64 inches
Now we can substitute these values into the formula:
SA = B + Ph = 14.65 + 13.64 * 11 = 260.04 square inches
Rounded to the nearest tenth, the surface area of the vase is 260.0 square inches.

The value of x and y obtained when multiplying equations to eliminate variable is y = -62/40 and x = -18/16.
What is elimination method?The elimination approach involves taking one variable out of the system of linear equations by utilizing addition or subtraction together with multiplication or division of the variable coefficients.
The given equations are:
5x - 3y = 6, and
2x + 5y = -10
Isolate the value of x in the following equation:
5x - 3y = 6
5x = 6 + 3y
x = (6 + 3y)/5
Substitute the value of x as follows:
2x + 5y = -10
(2) (6 + 3y)/5 + 5y = -10
12 + 15y + 25y = -50
40y = -50 -12
40y = -62
y = -62/40
Substitute the value of y to find the value of x:
2x + 5(-62/40) = -10
16x - 62 = -80
16x = -80 + 62
16x = -18
x = -18/16

According to the question
The first integral, the integral from 2 to 5 of dx over amount x squared minus 1, is incorrect because the denominator x2-1 becomes 0 at x=1, meaning the integrand expands to infinity at these places and the integral is not convergent across the range [2,5]. Since the interval of integration extends from 1 to infinity and the function is not limited, the second integral, the integral from 1 to infinity of amount x minus 1 dx, is incorrect.

If Oliver meets his goal, how many minutes will he read in all during the two months?
Using percentages we know that he read for 945 minutes over two months, covering pages. If Oliver accomplishes his goal of reading for 19% more minutes next month.
What is the percentage?Since one percent (symbolized as 1%) is equal to one-hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.
As an illustration, 1% of 1,000 chickens is equal to 1/100 of 1,000, or 10 birds, and 20% of the quantity is equal to 20% of 1,000, or 200.
So, this month, Oliver read for 450 minutes.
He has promised to read for 10% extra minutes the following month.
Next month, he spent minutes reading pages:
450 + 10% * 450 = 450 + 45 = 945
He, therefore, read for pages at a time for two months = 450+495=945
Hence He read for 945 minutes over two months, covering pages.

Factorise fully 20xy - 54
Plss answer
The factorisation of 20xy - 54 can be expressed as 2( 10xy - 27 ).
What is factorisation?The concept here is the factorisation . The breaking or decomposition of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorization or factoring in mathematics.
A number or other mathematical object is factorized or factored when it is written as the product of numerous factors, typically smaller or simpler things of the same kind.
We were given, 20xy - 54, we can see that that factor of 2 is common for both 20xy and 54.
Then we can factorize as 2( 10xy - 27 ).

(Show your work please) Rewrite in simplest rational exponent form square root of x times the fourth root of x. Show each step of your process.Rewrite in simplest rational exponent form square root x times 4 square root x
By applying the exponential properties, it can be concluded that the simplest rational exponent is [tex]x^{\frac{3}{4} }[/tex]
Exponential is a repeated multiplication method with the same number, which is notated in the form aⁿ, where a is called the base and n is the exponent or power.
Some properties of exponent:
[tex]a^{x}[/tex] x [tex]a^{y}[/tex] = [tex]a^{x+y}[/tex]
[tex]a^{x}[/tex] : [tex]a^{y}[/tex] = [tex]a^{x-y}[/tex]
[tex](a^{x}) ^{y}[/tex] = [tex]a^{xy}[/tex]
[tex](\frac{a}{b} )^{x}[/tex] = [tex]\frac{a^{x} }{b^{x} }[/tex]
a⁰ = 1
a⁻ˣ = 1 / aˣ
In mathematics, a radical is described as [tex]\sqrt[n]{x}[/tex], where n is a positive integer ≥ 1 and x is a real number. Then n is called the index of the radical, x is the radicand, and the symbol √ is the radical.
The radical can be written as a rational exponent as follows:
[tex]\sqrt[n]{x} = x^{\frac{1}{n} }[/tex] or [tex]\sqrt[n]{x^{m} } = x^{\frac{m}{n} }[/tex]
From the problem, we can denote the expression as follows:
square root of x = √x
the fourth root of x = ⁴√x
The product of the two expressions will be:
(√x) x (⁴√x) = [tex]x^{\frac{1}{2}}[/tex] x [tex]x^{\frac{1}{4} }[/tex]
= [tex]x^{\frac{3}{4} }[/tex]
Thus the simplest rational exponent is [tex]x^{\frac{3}{4} }[/tex]

How to graph a linear function
Linear functions are polynomials of the form:
y = m · x + b
Where:
m - Slopeb - Interceptx - Independent variabley - Dependent variableGraphically speaking, linear functions represents lines and lines can be generated from two points on Cartesian plane. The procedure is described below.
First, obtain two points from linear function:
x = 0
y = - (1 / 3) · 0 - 6
y = - 6
x = 1
y = - (1 / 3) · 1 - 6
y = - 1 / 3
Second, add the points on Cartesian plane.
Third, construct a line that passes through the two points added. Please see the image attached below.
