The double number line shows that Bira has ridden 28m on a carousel, which is 80% of a full rotation on the carousel
The distances that represent the percentages are given as follows:
Distance of 28 m -> 80% of a rotation.Distance of 7 m -> 20% of a rotation.Distance of 35 m -> 100% of a rotation.What is a proportion?A proportion is a fraction of a total amount, used along with the unit measures and basic arithmetic operations to obtain the desired measures in the context of a problem.
28m is 80% of the distance, hence 100% of the distance is obtained applying the proportion as follows:
0.8x = 28
x = 28/0.8
x = 35.
Then the distance that represents 20% of a rotation is calculated as follows:
0.2 x 35 = 7 meters.

give an example of a function that is discontinuous at one and only one point in its domain but is continuous at every other point is your point of discontinuity removable or essential
An example of a function that is discontinuous at one and only one point in its domain but is continuous at every other point is the function
f(x) = x^2.This function is continuous at every point in its domain, which is the set of all real numbers (-infinity < x < infinity). However, at the point x = 0, the function is discontinuous.
At x = 0, the function f(x) = x^2 is equal to 0, but if we approach the point x = 0 from the left (x = -0.1, -0.01, etc.), the function is equal to a negative value (-0.01, -0.0001, etc.), and if we approach the point x = 0 from the right (x = 0.1, 0.01, etc.), the function is equal to a positive value (0.01, 0.0001, etc.). This means that the function is not continuous at the point x = 0, and is therefore discontinuous at this point.
The point of discontinuity in this example is an essential discontinuity, which means that it cannot be removed by redefining the function at that point. This is because the function f(x) = x^2 is defined differently for x < 0 and x > 0, and there is no way to redefine the function at x = 0 to make it continuous.

Solve. p/1 6/7=−4.4(refer to the picture)
enter your answer as a mixed number in simplest form in the box.
Answer:
p = -8 6/35
Step-by-step explanation:
p/(1 6/7)=−4.4
To solve for p, multiply each side by 1 6/7
p/(1 6/7) * ( 1 6/7)=−4.4 * (1 6/7)
p = - 4.4 * ( 1 6/7)
Change each number to fractions
p = -44/10 * 13/7
p = -286/35
Change to a mixed number
p = -8 6/35
which of the following conditions must be met to conduct a two-proportion significance test? the populations are independent. the probabilities of success multiplied by the sample sizes are greater than or equal to 10 and the probabilities of failure multiplied by the sample sizes are greater than or equal to 10 for each population. each sample is a simple random sample.
All the given three conditions are true for conducting a two proportion significance test.
To check the significance of two proportions, following conditions should be met
Data of each group must be collected from the population using a random sampling. That means data values must be independent.Population should be independent of each other.The two populations must be approximately or normally distributed. To check the assumption of the normality, we have the following condition: “The probabilities of success multiplied by the sample sizes are greater than or equal to 10 and the probabilities of failure multiplied by the sample sizes are greater than or equal to 10 for each population.” If this condition is met, we say that populations are normally distributed.Hence, all the three conditions must be met to conduct a two-proportion significance test.

what is Prime factorization method?
Writing all numbers as the product of primes is a procedure known as prime factorization. Consider the case of the number 20, for instance. We can divide that into two elements. Well, that's four times five, we can say. Furthermore, 5 is a prime number.
Solution:
HCF = ( X, 54 ) = 6
LCM = ( X, 54 ) = 432
a = x b = 54
using property
a * b = LCM * HCF
54a = 6 * 432
a = (6 * 432) / 54

How do I solve a whole number and a fraction?
Answer:
To solve a problem involving a whole number and a fraction, you can first convert the whole number to a fraction by writing it as a fraction with a denominator of 1. For example, if the whole number is 4, you can write it as the fraction 4/1.
Then, you can add or subtract the fractions as you would normally, making sure to find a common denominator if necessary. For example, suppose you want to add the whole number 4 and the fraction 3/5. You can first write 4 as the fraction 4/1, giving you:
4/1 + 3/5
To add these fractions, you need to find a common denominator. A common denominator for 1 and 5 is 5, so you can rewrite the fractions with denominators of 5:
4/1 = 20/5
3/5 = 3/5
Now you can add the fractions:
20/5 + 3/5 = 23/5
So the solution to the problem is 23/5.
If you need to multiply or divide the whole number and fraction, you can treat the whole number as a fraction with a denominator of 1 and then perform the multiplication or division as you would normally with fractions.

6(2x + 4)² = 2x + 4 + 2.x^4 - 6x² - 27 = 0.6x^4 = -x² + 5.What is a quadratic equation?The degree of a function is given by the highest exponent that appears in the definition of the function.
A quadratic function is a function that has a degree of 2.
The standard format of a quadratic function is given as follows:
y = ax² + bx + c.
(in which the coefficient a must assume a value different of zero).
The quadratic function in this problem is given as follows:
6(2x + 4)² = 2x + 4 + 2.
As (2x + 4)² = 4x² + 16x + 16, meaning that the highest exponent would be of 2.
However, equations of the fourth degree can also be quadratic in form, as long as the exponents go as follows: 4, 2 and 0.
Hence these following equations are also quadratic in form:
x^4 - 6x² - 27 = 0.6x^4 = -x² + 5.They are classified as quadratic in form because a transformation such as y = x² can make them quadratic.

Cans of paint weigh 6 pounds each. Let x represent the number of cans of paint and y represent the total weight of the cans. Write the equation to this situation as slope intercept form (y=mx+b). Then create a table of possible values
The equation for the relationship between the number of cans of paint, x, and the total weight of the cans, y, in slope-intercept form is y = 6x + 0. This equation can be derived from the formula for the slope-intercept form of a line, y = mx + b, where m is the slope of the line and b is the y-intercept. In this case, since the weight of each can of paint is 6 pounds and there is no y-intercept (the line passes through the origin), the slope of the line is 6 and the y-intercept is 0.
A table of possible values for the number of cans of paint, x, and the total weight of the cans, y, based on this equation is shown below:
x (number of cans of paint) y (total weight of cans)
1 6
2 12
3 18
4 24
5 30
As the table shows, for each additional can of paint, the total weight of the cans increases by 6 pounds. This is because each can of paint weighs 6 pounds, and the weight of the cans is equal to the number of cans multiplied by the weight of each can.
Answer: y = 6x
Step-by-step explanation:
For each can of paint (x) 6 pounds is added. This is represented as;
y = 6x
For the table of possible values, we will plug a value in for x, and then evaluate the function for y. See attached.
y = 6(1) = 6
y = 6(2) = 12
y = 6(3) = 18

Fwam is a high school basketball player. In a particular game, he made some free throws (worth one point each) and some three point shots. Fwam made a total of 10 shots altogether and scored a total of 18 points. Graphically solve a system of equations in order to determine the number of free throws made, x, and the number of three point shots made, y.
Answer:
x = 6 ans y=4
Step-by-step explanation:
The number of free throws made = x
The number of three points shots made = y
We can make an equation
x+y= total shots made
x+y= 10
So if we want "x",
x=10-y (First equation)
x is one point
y is three point
We can make another equation on how much points gained
(1)x + 3(y) = total points gained
x + 3y =18
If we want "x" ,
x =18-3y (second equation).
Now that we got two equation solve the question with simultaneous equations
x=10-y
x=18-3y
Substitute "x=18-3y" into equation 1
18-3y=10-y
10-y=18-3y
3y-y=18-10
2y=8
y=4 (Three points shots)
x=10-y
x=10-4
x=6 (Free throws made)
Therefore , x=6 and y=4

What is a null hypothesis?
Two alternatives being the same is the null hypothesis. The underlying assumption is that the observed difference is just the result of chance. It is feasible to estimate the probability that the null hypothesis is correct using statistical testing.
Here, we have
The objective of this experiment is to compare two compounds, designed to reduce braking distance, used in tire manufacturing to prove if the braking distance of SUVs equipped with tires made with compound 1 is shorter than the braking distance of SUVs equipped with tires made with compound 2.
So you have 2 independent populations, SUV's equipped with tires made using compound 1 and SUVs equipped with tires made using compound 2.
Two samples of 66 braking tests are made and the braking distance was measured each time, the study variables are determined as:
X₁: Braking distance of an SUV equipped with tires made with compound one.
Its sample mean is X[bar]₁= 41 feet
And the Standard deviation S₁= 12.1 feet
X₂: Braking distance of an SUV equipped with tires made with compound two.
Its sample mean is X[bar]₂= 46 feet
And the Standard deviation S₂= 9.0 feet
We don't have any information on the distribution of the study variables, nor the sample data to test it, but since both sample sizes are large enough n₁ and n₂ ≥ 30 we can apply the central limit theorem and approximate the distribution of both variables sample means to normal.
The researcher's hypothesis, as mentioned before, is that the braking distance using compound one is less than the distance obtained using compound 2, symbolically: μ₁ < μ₂
The statistical hypotheses are:
H₀: μ₁ ≥ μ₂
H₁: μ₁ < μ₂
α: 0.05
The statistic to use to compare these two populations is a pooled Z test
Z= {(X[bar]₁-X[bar]₂) - (μ₁ - μ₂)}/√S₁²/n₁+S₂²/n₂ ≈ N(0;1)
Z = {(41-46)-0}/√146.41/66+81/66
Z = -5/1.85
Z = -2.70
The rejection region of this hypothesis test is one-tailed to the right, so you'll reject the null hypothesis to small values of the statistic. The critical value for this test is:
Z(α) = Z(0.05) = -1.645
Decision rule:
If Z(H₀) ≥ -1.645, then you do not reject the null hypothesis.
If Z(H₀) < -1.645, then you reject the null hypothesis.
Since the statistic value is greater than the critical value, the decision is to not reject the null hypothesis.
At a 5% significance level, you can conclude that the average braking distance of SUVs equipped with tires manufactured used compound 1 is greater than the average braking distance of SUVs equipped with tires manufactured used compound 2.
Hence, the critical value is -2.70.

Three key features of a linear function are described as shown.
• The graph of the function has a y-intercept of (0, 3) .
• The function is increasing over its entire domain.
• The x-intercept of the function is (-4, 0).
Step-by-step explanation:
the slope-intercept form is
y = ax + b
a being the slope, b being the y-intercept (the y-value when x = 0), which we get from (0, 3) : 3.
the slope is the ratio (y coordinate difference / x coordinate difference) when going from one point on the line to another.
we got 2 points, so, let's use them :
(-4, 0) and (0, 3)
x changes by +4 (from -4 to 0).
y charges by +3 (from 0 to +3).
so, the slope is +3/+4 = 3/4.
therefore, our equation is
y = f(x) = (3/4)x + 3

An experiment was conducted in which planks of wood painted red and green were shown to pigeons to investigate a pigeon's ability to select a certain color. Pigeons could accurately select the color of the plank of wood 20 percent of the time. A simulation was conducted in which a trial consisted of a pigeon being shown eight planks of wood and its number of successes being recorded. This process was repeated many times, and the results are shown in the histogram.
Based on the results of the simulation, which of the following is closest to the probability that there were at most three successes in a trial?
The probability that there were at most three successes in a trial is approximately 0.9.
It looks like the histogram shows the probability mass function (PMF) for the number of successes in a trial. The PMF for a random variable gives the probability of each possible value of the random variable.
To find the probability that there were at most three successes in a trial, we need to add up the probabilities of 0, 1, 2, and 3 successes. From the histogram, it looks like the probabilities of these values are approximately 0.2, 0.4, 0.2, and 0.1, respectively. Adding these up, we get an approximate probability of 0.2 + 0.4 + 0.2 + 0.1 = 0.9.
Therefore, the probability that there were at most three successes in a trial is approximate $\boxed{0.9}$.

What are the characteristics of a triangle?A triangle in geometry is a three-sided polygon with three edges and three vertices. The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic. This characteristic is known as the triangle's angle sum property.
Calculation:Given that ΔHPS≅ΔCNF.
We can see that angle H in triangle HPS is obtuse whereas angle N in triangle CNF is obtuse so comparing this we get,
6x - 29 = 115
6x = 144
x = 24
Comparing angle C and angle P we get
4z - 32 = 36
4z = 68
z = 17
Now the remaining angle in trinagle CNF is angle F which is 3y - 1 as we know that sum of angles in a triangle is 180 and the angle C and N are 36 and 115 we can say that F is 29
Now to find y we equalise it to 29
3y - 1 = 29
3y = 30
y = 10.

Draw a line segment with a length of 3 1/2 and a midpoint of -1.
The line segment of length 3 1/2 is sketched with mid pint at -1 and attached
What is a line segment?A line segment in geometry has two different points on it that define its boundaries.
A line segment is sometimes referred to as a section of a line that links two places. The difference between a line and a line segment is that a line has no endpoints and can go on forever in either direction.
How to make the line segmentThe endpoints is important before a line can be defined as a line segment, however the midpoint will be essential in calculating for the endpoints
The mid point of the line is given to be -1
the other ends will be 3 1/2 /2
1.75
from -1 add and subtract 1.75 to get the endpoint's
-1 + 1.75 = 0.75
-1 - 1.75 = 2.75
each unit on the number line is 0.3333
to get 0.75 from 0 count two units to give 0.6667 then a bit more to get to 0.75
to get 2.75 from 2 count two strokes to get to 2.6667, then add a little more to get 2.75

could any one please help me with this question
Answer:
10°
Step-by-step explanation:
The sum of the measures of the exterior angles of any polygon, one per vertex, is 360°.
x + 3x + 4x + 5x + 6x + 8x + 9x = 360
36x = 360
x = 10
In a polygon, an exterior angle is supplementary to its adjacent interior angle.
The smallest exterior angle is x, and x = 10.
Answer: 10°
Which of the following shows a correct method to calculate the surface area of the cylinder?
cylinder with diameter labeled 2.8 feet and height labeled 4.2 feet
SA = 2π(2.8)2 + 2.8π(4.2) square feet
SA = 2π(1.4)2 + 2.8π(4.2) square feet
SA = 2π(2.8)2 + 1.4π(4.2) square feet
SA = 2π(1.4)2 + 1.4π(4.2) square feet
You can quickly calculate the radius of a cylinder using an online calculator.
How to Find Radius of a Cylinder?The term "cylinder" refers to a three-dimensional solid shape made up of two circular bases joined by two parallel lines. We may calculate the radius of the cylinder using the formula for cylinder volume.A cylinder's capacity or the quantity of space it takes up are both determined by the cylinder's volume. V = πr²h, a formula, is used to compute it.Cylinder radii (r) √(V / π × h), where V denotes a cylinder's volume, h denotes its height, and (Pi) denotes a mathematical constant having a roughly 3.14 value.Solved Examples on the Radius of a Cylinder Calculator ExampleWhat is the radius of a cylinder with a capacity of 100 cubic units and a height of 5 units?
Solution:
The radius of a cylinder (r) is equal to (V / h).
= √(100 / π × 5)
= 2.523 units
As a result, a cylinder's radius is 2.523 units.
