2.0 - 2.9 5
3.0 - 3.9 2
4.0 - 4.9 1
Step-by-step explanation:
The scale of equal intervals is characterized by a common and constant unit of measure that assigns a number equal to the number of units equivalent to that of the magnitude of the observed element. It is important to note that the zero point in the scales of equal intervals is arbitrary, and does not reflect at any moment absence of the magnitude that we are measuring.
This scale, besides having the characteristics of the ordinal scale, we find that the assignment of the numbers to the elements is so precise that we can determine the magnitude of the intervals (distance) between all the elements of the scale. Undoubtedly, we can say that the scale of intervals is the first truly quantitative scale and the characters that have this scale can be calculated all the statistical measures except the coefficient of variation.
The data is classified into classes divided into equivalent intervals. The range is then divided by the number of classes, which gives the common difference.
1. Define the number of equals intervals .
Each interval increase 0.9.
2. Make a frecuency table.
We select each country which is within the range of each class and we add in the frecuency column the countries that fall within the range of that class.

You and a friend are stunt pilots, performing in an air show. The path of your airplane is modeled by the
equation y = −6x − 5, and your friend’s path is modeled by the equation
y = −4x^2 − 13x − 12. Do your paths cross each other? If so, then what are the coordinates of the point(s) where the paths meet?
ANSWER
The paths do not cross each other.
EXPLANATION
The equation that models one of the paths is
[tex]y = - 6x - 5[/tex]
and the other is modeled by:
[tex]y = - 4 {x}^{2} - 13x - 12[/tex]
We equate the two equations and solve for their point of intersection.
[tex]- 4 {x}^{2} - 13x - 12 = - 6x - 5[/tex]
[tex]- 4 {x}^{2} - 13x + 6x- 12 + 5 =0[/tex]
[tex]- 4 {x}^{2} - 7x- 7 =0[/tex]
[tex]4 {x}^{2} + 7x + 7 =0[/tex]
The discriminant is
[tex]D= {b}^{2} - 4ac[/tex]
[tex]D= {7}^{2} - 4(4)(7) = - 63[/tex]
The discriminant is negative so the equation has no real roots.
This means that, the two paths do not cross.

The parabola y=x^2 is reflected across the x-axis and then scaled vertically by a factor of 1/6
Answer:
y = (-1/6)x^2
Step-by-step explanation:
Original function and graph: y = x^2
Reflection across the x-axis is y = -x^2
Vertical scaling by a factor of 1/6: y = (-1/6)x^2
The given parabola y=x^2 when reflected over the x-axis becomes y=-x^2. After applying a vertical scale factor of 1/6, it becomes y = -(1/6)x^2.
Explanation:The parabola given, y=x^2, when reflected across the x-axis, results in a graph of y = -x^2.
Then, when we apply vertical scaling by a factor of 1/6, we have to multiply the y-values by this factor. If y = -x^2 is our equation after reflecting, then after scaling, it becomes y = -(1/6)x^2.
A key point to remember is that when a parabola is reflected over the x-axis, it flips upside down. Then, when it's vertically scaled by a factor, we multiply the y-values by the factor, which stretches or squishes the graph depending on the factor's value.

Let (-6,-5) be a point on the terminal side of theta
Find the exact value of sin theta, csc theta, and cot theta
Answer:
Part 1) [tex]sin(\theta)=-\frac{5\sqrt{61}}{61}[/tex] or [tex]sin(\theta)=-\frac{5}{\sqrt{61}}[/tex]
Part 2) [tex]csc(\theta)=-\frac{\sqrt{61}}{5}[/tex]
Part 3) [tex]cot(\theta)=\frac{6}{5}[/tex]
Step-by-step explanation:
we know that
The point (-6,-5) lies on the III Quadrant
so
sin(theta) is negative
csc(theta) is negative
cot(theta) is positive
Part 1) Find the sine of angle theta
we know that
The function sine is equal to divide the opposite side to the angle theta by the hypotenuse
[tex]sin(\theta)=\frac{y}{r}[/tex]
we have
[tex]x=6\ units,y=5\ units[/tex]
Applying the Pythagoras Theorem
[tex]r^{2}=x^{2}+y^{2}[/tex]
substitute
[tex]r^{2}=6^{2}+5^{2}[/tex]
[tex]r^{2}=61[/tex]
[tex]r=\sqrt{61}\ units[/tex] -----> the hypotenuse
substitute
[tex]sin(\theta)=\frac{5}{\sqrt{61}}[/tex]
Simplify
[tex]sin(\theta)=\frac{5\sqrt{61}}{61}[/tex]
Remember that the sin(theta) is negative
so
[tex]sin(\theta)=-\frac{5\sqrt{61}}{61}[/tex]
Part 2) Find the cosecant of angle theta
we know that
The function cosecant is equal to divide the hypotenuse by the opposite side to the angle theta
[tex]csc(\theta)=1/sin(\theta)=\frac{r}{y}[/tex]
we have
[tex]sin(\theta)=-\frac{5}{\sqrt{61}}[/tex]
so
[tex]csc(\theta)=-\frac{\sqrt{61}}{5}[/tex]
Part 3) Find the cotangent of angle theta
we know that
The function cotangent is equal to divide the adjacent side to the angle theta by the opposite side to the angle theta
[tex]cot(\theta)=\frac{x}{y}[/tex]
we have
[tex]x=6\ units,y=5\ units[/tex]
substitute
[tex]cot(\theta)=\frac{6}{5}[/tex]
The exact values of sin theta, csc theta, and cot theta for a point (-6, -5) on the terminal side are -5/sqrt(61), sqrt(61)/-5, and 6/5 respectively.
Explanation:In this problem we have a point (-6, -5) on the terminal side of theta. The x-coordinate corresponds to the cosine of theta and the y-coordinate corresponds to the sin theta.
To answer your question:
sin theta = y/r = (-5)/sqrt((-6)^2+(-5)^2) = -5/sqrt(61)csc theta = 1/sin(theta) = sqrt(61)/-5cot theta = cos(theta)/sin(theta) = x/y = -6/-5 = 6/5Learn more about Trigonometric Values here:https://brainly.com/question/29069676

What is the length of side BC? Round the answer to the nearest tenth.
Answer:
The length of side BC is 2.8 units
Step-by-step explanation:
* Lets revise how to find the distance between two points
- If there are two points their coordinates are (x1 , y1) and (x2 , y2),
then we can find the distance between them by this rule:
d = √[(x2 - x1)² + (y2 - y1)²]
- Now lets solve the problem
∵ B = (3 , 3)
∵ C = (5 , 1)
- To find the length of BC use the rule of the distance above
- Let point B is (x1 , y1) and point C is (x2 , y2)
∵ x1 = 3 and x2 = 5
∵ y1 = 3 and y2 = 1
∴ BC = √[(5 - 3)² + (1 - 3)²]
∴ BC = √[(2)² + (-2)²]
∴ BC = √[4 + 4] = √8 = 2.8 units
* The length of side BC is 2.8 units
Answer: Its 2.8 when rounded to the nearest tenth. :)
A shade of green paint is made by mixing yellow paint and blue paint in the ratio 5:2. Mel has 30 litres of yellow paint and 9 litres of blue paint.what is the maximum amount of green paint she can make?
Answer:
31.5 litres
Step-by-step explanation:
If Mel uses all 30 litres of yellow paint, then:
5 / 2 = 30 / x
5x = 60
x = 12
Mel would need 12 litres of blue paint, but she only has 9 litres. So the amount of yellow paint she needs is:
5 / 2 = x / 9
2x = 45
x = 22.5
Mel will use 22.5 litres of yellow paint with 9 litres of blue paint to make a total of 31.5 litres of green paint.
She can make a maximum of 28 litres of green paint.
To find the maximum amount of green paint Mel can make with her yellow and blue paint, we must use the ratio of 5:2 (yellow to blue) given for mixing the green paint.
Firstly, calculate the number of batches of green paint that can be made with the available yellow paint:
Mel has 30 litres of yellow paint and needs 5 litres per batch of green paint, so she can make 30 ÷ 5 = 6 batches from the yellow paint.
Next, calculate the number of batches that can be made with the blue paint:
Mel has 9 litres of blue paint and needs 2 litres per batch of green paint, so she can make 9 ÷ 2 = 4.5 batches from the blue paint.
However, since we cannot have half a batch, the maximum number of full batches Mel can produce from the blue paint is 4.
The limiting reactant here is the blue paint since it allows fewer batches to be made. Therefore, Mel can only make 4 full batches of green paint.
To find the total amount of the green paint from the batches:
Combine the ratios, which add up to 7 parts (5 parts yellow and 2 parts blue).
Multiply the number of batches by the sum of the parts: 4 batches × 7 parts per batch = 28 litres of green paint.
Thus, the maximum amount of green paint Mel can make is 28 litres.

What are the zeros of the polynomial function f(x)=x^3-2x^2-8x?
HELP NEEDED !!!! read closely!!!
A. -2,4
B. -2,0,4
C. -4,2
D. -4,0.2
Answer: -2, 0, 4
Set the equation equal to zero.
x³ - 2x² - 8x = 0
Factor out x in the equation, since all the terms (x³, -2x², and -8x) are divisible by x. You can check your accuracy using the Distributive Property.
x(x² - 2x - 8) = 0
Factor out the polynomial. To do this, find two numbers that multiply to get the last term, -8, and add together to get the middle term, -2. In this case, those two numbers are -4 and 2 (-4 × 2 = -8 and -4 + 2 = -2). Don't forget about the x that was factored out before!
x(x - 4)(x + 2) = 0
Set each factor equal to zero and solve for x. The factors in the equation are x, (x - 4), and (x + 2).
x = 0(x - 4) = 0x = 4
(x + 2) = 0x = -2
The zeros of the polynomial function are -2, 0, and 4.
mr. cuddy draws a triangle with a perimeter of 36cm. Principal Aranda says that the longest side measures 18 cm, How do you know that the principal Aranda is incorrect? Explain
Answer:
See the procedure
Step-by-step explanation:
we know that
The Triangle Inequality Theorem, states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side
Let
a,b,c the lengths side of triangle
c is the greater side
The perimeter is equal to
P=a+b+c
P=36 cm
If c=18 cm
then
a+b=18
Applying the Triangle Inequality Theorem
a+b > c
18 > 18 ----> is not true
therefore
Principal Aranda is incorrect
The larger side cannot measure 18 cm
The largest side must be less than 18 cm

c = - 2, c = 7
Step-by-step explanation:
Given
c² - 14 = 5c ( subtract 5c from both sides )
c² - 5c - 14 = 0 ← in standard form
To factorise the quadratic
Consider the factors of the constant term (- 14) which sum to give the coefficient of the c- term (- 5)
The factors are - 7 and + 2, since
- 7 × 2 = - 14 and - 7 + 2 = - 5, hence
(c - 7)(c + 2) = 0
Equate each factor to zero and solve for c
c - 7 = 0 ⇒ c = 7

Write probability in a fraction
Answer:
[tex]P (even,\ then\ not\ 2) = \frac{5}{12}[/tex]
Step-by-step explanation:
When launching a numerical cube there are 6 possible results
S = {1, 2, 3, 4, 5, 6}
Among these possible outcomes only 3 are even numbers
S = {2, 4, 6}
So the probability of obtaining an even number is
[tex]P = \frac{3}{6}\\\\P = \frac{1}{2}[/tex]
Then, the probability of obtaining a number other than 2 is:
[tex]P = \frac{5}{6}[/tex].
If 2 launches are made then the events are independent,
Thus:
P(even, then not 2) is
[tex]P (even,\ then\ not\ 2) = \frac{1}{2} * \frac{5}{6}\\\\P (even,\ then\ not\ 2) = \frac{5}{12}[/tex]
What percent of the figure is shaded?
40% of the figure is shaded.
The image depicts many grids. These small squares has 10 rows and 10 columns. So, the total number of squares are:
10 x 10=100 squares.
Out of 100 squares, 4 rows and their 10 columns are shaded. So,
4*10=40 squares
So, 40 squares are shaded. To find the percentage we can use the formula:
Shaded/ Total Squares x 100
= 40/100 x 100
= 40%
Therefore, 40 percent of the figure is shaded.
To find what percent of a figure is shaded, calculate the shaded area divided by the total area and multiply by 100. In probability distributions, shading indicates the probability that a variable falls within a specific range, such as the 80th or 90th percentile of a distribution.
Explanation:To determine what percent of the figure is shaded, one must first understand the concept of percentage calculations. The percentage is computed by dividing the part (shaded area) by the total area, then multiplying by 100. In the case of probability distributions, the shaded area represents a probability, such as the probability of a variable falling between two values, or the specific percentile of a distribution.
For example, if we have a graph with a horizontal axis for X, and we need to shade the region corresponding to a certain probability or percentile, we need to identify the region under the curve that equates to that percentage. This could involve calculating the area between two x-values or finding a value that corresponds to a given area under the curve, such as the 80th percentile or 90th percentile. To express the result as a percentage, multiply the probability by 100.
Sometimes, the question may provide specific conditions, such as indicating that the shaded area under one curve is equal to the area of another shape, like a rectangle or another curve. In this case, we can assume the two percentages are equal and express the probability of one as the same percentage as the other.

We can round the original price of the jacket to 100 dollars
30% off means we pay 70%
70 % of 100
.70*100 = 70
The jacket will cost just less than 70 dollars
Our estimate is high since we rounded up
what are the explicit equation and domain for geometric sequence with a first term of 4 and a second term of -8
ANSWER
[tex]a_n=4( { (- 2)}^{n - 1} )[/tex]
for n≥1
EXPLANATION
The explicit equation for a geometric sequence is found using the formula:
[tex]a_n=a_1( {r}^{n - 1} )[/tex]
where
[tex]a_1 = 4[/tex]
is the first term and
[tex]r =\frac{- 8}{4}=-2[/tex]
is the common ratio.
We substitute the values into the formula to obtain,
[tex]a_n=4( { (- 2)}^{n - 1} )[/tex]
This is the explicit formula for the geometric sequence.
The domain is n≥1
