What do you mean by Percentage?A number can be expressed as a fraction of 100 using a percentage. It is represented by the number %.
A decimal or fraction can be multiplied by 100 to become a percentage. For instance, multiplying 0.75 (a decimal) by 100 yields 75% when converted to a percentage. The same can be done to convert 3/4 (a fraction) to a percentage by dividing 3 by 4 to get 0.75, then multiplying that number by 100 to get 75%.
To calculate the population of Medina, Ohio in 7.3 years, we can use the formula:
Population after n years = Population before ×(1 + r/100)²
where r is the annual growth rate and n is the number of years.
Substituting the given values, we get:
Population after 7.3 years = 26,190 × (1 + 3.7/100)^7.3
Population after 7.3 years = 26,190 * 1.037^7.3
Population after 7.3 years = 26,190 * 1.301
Population after 7.3 years = 34,052.9
Rounding to the nearest hundredth, we get:
Population after 7.3 years = 34,052.90 ≈ 34,052.89
Therefore, the population of Medina, Ohio will be approximately 34,052.89 people in 7.3 years.

translate the triangle 3 to the right and 2 down
According to the assumption the translated triangle would have vertices at (4,0), (6,2), and (5,-1).
Given,
To translate a triangle 3 units to the right and 2 units down, we would take each point of the original triangle and add 3 to the x-coordinate and subtract 2 from the y-coordinate.
For example, if the original triangle has vertices at (1,2), (3,4), and (2,1), the translated triangle would have vertices at:
(1+3, 2-2) = (4,0)
(3+3, 4-2) = (6,2)
(2+3, 1-2) = (5,-1)
So, the translated triangle would have vertices at (4,0), (6,2), and (5,-1).

temperature of 60°F and a temperature of 78°F?
25
A. 1°C
B. 5°C
C. 10°C
D. 18°C
The difference in centigrade degrees between a temperature of 60°F and a temperature of 78°F is 10°C.
Calculating the difference between the temperaturesTo convert Fahrenheit (°F) to Celsius (°C), you can use the following formula:
°C = (°F - 32) / 1.8
Using this formula, we can first convert 60°F to Celsius:
°C = (60°F - 32) / 1.8
°C = (28°F) / 1.8
°C = 15.56°C
Similarly, we can convert 78°F to Celsius:
°C = (78°F - 32) / 1.8
°C = (46°F) / 1.8
°C = 25.56°C
The difference in Celsius degrees between these two temperatures is:
Δ°C = 25.56°C - 15.56°C
Δ°C = 10°C
Therefore, the difference in centigrade degrees between a temperature of 60°F and a temperature of 78°F is 10°C.

MNOP is a trapezium. If MN//OP and A is the midpoint of NO prove : Area of triangle MAP = 1/2area of trapezium MNOP
To prove: Area of triangle MAP = 1/2 area of trapezium MNOP
Given: MN//OP and A is the midpoint of NO
Proof:
Let h be the height of trapezium MNOP.
The area of trapezium MNOP is given by:
Area of trapezium MNOP = (1/2) × (MN + OP) × h
Since MN//OP, we have MN = OP.
Therefore, Area of trapezium MNOP = (1/2) × 2MN × h = MN × h
Now, consider triangle MAP.
The base of triangle MAP is MA, which is half of NO.
Therefore, the base of triangle MAP is (1/2) × NO.
The height of triangle MAP is h, which is the same as the height of trapezium MNOP.
Therefore, the area of triangle MAP is given by:
Area of triangle MAP = (1/2) × (base) × (height) = (1/2) × (1/2NO) × h
Substituting NO = 2OA, we get:
Area of triangle MAP = (1/2) × (1/2 × 2OA) × h = (1/2) × OA × h
Since A is the midpoint of NO, we have OA = 1/2NO.
Therefore, Area of triangle MAP = (1/2) × (1/2NO) × h = (1/2) × (base of trapezium MNOP) × h
Hence, Area of triangle MAP = 1/2 Area of trapezium MNOP.
Therefore, the given statement is proved.
Answer: Given that MNOP is a trapezium with MN parallel to OP and A is the midpoint of NO.
To prove that the area of triangle MAP is half the area of trapezium MNOP, we need to use the following theorem:
Theorem: If a line segment joins the midpoint of one side of a triangle to a vertex opposite to that side, then the segment divides the triangle into two equal areas.
Proof:
Since A is the midpoint of NO, we can draw a line segment AP from vertex P to point A on NO as shown in the figure below:

M _______N

| \ |

O--------P
A
We can see that triangle MAP is formed by the line segment AP and side MP of the trapezium.
Also, we can see that triangle MAN is congruent to triangle NOP because they are both right triangles with corresponding sides parallel. Therefore, they have the same area.
Since MNOP is a trapezium, the area of trapezium is given by:
Area of trapezium MNOP = (1/2)(MN+OP) × height
Since MN is parallel to OP, the height of the trapezium is the same as the height of triangle MAN and NOP.
Therefore, the area of trapezium MNOP can be written as:
Area of trapezium MNOP = (1/2)(MN+OP) × height
= (1/2)(MA+AP+OP) × height
= (1/2)(MA+MP) × height (Since AP = NO/2 = height)
So, we have proved that:
Area of trapezium MNOP = (1/2)(MA+MP) × height
Using the theorem, we know that AP divides triangle MAP into two equal areas. Therefore,
Area of triangle MAP = (1/2) × Area of triangle MAP
Substituting the above in the expression for the area of trapezium, we get:
Area of trapezium MNOP = Area of triangle MAP + (1/2) × Area of triangle MAP
= (3/2) × Area of triangle MAP
Therefore, we have:
Area of triangle MAP = (1/2) × Area of trapezium MNOP
Thus, we have proved that the area of triangle MAP is half the area of trapezium MNOP.

Which equation of a circle has the center, C, and radius, r, as shown in the graph?
The equation of a circle given by the graph is (x-3)²+(y+2)²=29,
hence option b is correct.
A circle is a closed curve that extends outward from a set point known as the center, with each point on the curve being equally spaced from the center. A circle with an (h, k) center and a radius of r has the equation:
(x-h)² + (y-k)²= r²
This is the equation's standard form. Hence, we can quickly determine the equation of a circle if we know its radius and center coordinates.
We know that the equation of the circle is -
[tex](x-h)^2+(y-k)^2=r^2[/tex]
where (h,k) is the center of the circle and r is the radius,
given that,
center of the circle is = (3,-2)

On 36 acres of land , there are a total of 2808 trees. If the trees are sread out evenly , how many trees are on each acre of land ?
There are approximately 78 trees on each acre of land when the trees are spread out evenly.
To find the number of trees on each acre of land mathematically, we can use the formula for average or mean.
The average number of trees per acre can be found by dividing the total number of trees by the total number of acres. In this case, we have 2808 trees and 36 acres:
Average number of trees per acre = Total number of trees / Total number of acres
Average number of trees per acre = 2808 / 36
Average number of trees per acre = 78
Therefore, there are approximately 78 trees on each acre of land when the trees are spread out evenly.
This means that if the land is divided into 36 equal sections, each section will have approximately 78 trees.

Assume the random variable x is normally distributed with mean u=89 and standard deviation o=4. Find the indicated probability. P(x<87)
The random variable x is normally distributed with mean u=89 and standard deviation o=4. The indicated probability, P(x<87)= 0.3085.
Describe Standard Deviation?In statistics, standard deviation is a measure of the amount of variation or dispersion in a set of data. It is a commonly used measure of the spread of a distribution and is calculated as the square root of the variance.
A higher standard deviation indicates that the data points are more spread out from the mean, while a lower standard deviation indicates that the data points are more tightly clustered around the mean.
Standard deviation is an important concept in statistics and is used in many statistical analyses, such as hypothesis testing and confidence interval estimation. It is also used in finance and economics to measure the risk associated with investments and to assess the variability of economic data.
To solve this problem, we need to standardize the value using z-score formula.
z = (x - mu) / sigma
Here, x = 87, mu = 89, and sigma = 4.
z = (87 - 89) / 4 = -0.5
We can look up the corresponding area under the standard normal distribution curve using a table or calculator. The area to the left of z = -0.5 is 0.3085.
Therefore, P(x < 87) = P(z < -0.5) = 0.3085.

what is 95.2% confidence interval in z-score
A 95.2% confidence interval in z-score is a range of values that is likely to contain the true population mean with a probability of 95.2%. The z-score for a 95.2% confidence interval is approximately ±1.97.
To calculate the 95.2% confidence interval in z-score, we can use the following formula:
CI = X ± z × (σ/√n)
where X is the sample mean, σ is the population standard deviation, n is the sample size, and z is the critical value from the standard normal distribution table.
For a 95.2% confidence interval, the area in the tails of the standard normal distribution is 0.024 (0.5 - 0.952/2). Therefore, the critical z-value for a 95.2% confidence interval is approximately ±1.97.
This formula assumes that the sample follows a normal distribution, or that the sample size is large enough to satisfy the central limit theorem.

A manufacturer of pencils randomly selects 25 pencils and measures their length (in inches). Their data is shown. Create a frequency distribution with 6 classes and a class width of 0.4 inches. What is the shape of the frequency histogram?
The histogram is bimodal.
The histogram is roughly symmetrical.
The histogram is skewed right.
The histogram is uniform.
The histogram is skewed left.
Answer:
A) The histogram is bimodal.
Answer:
To create a frequency distribution, we first need to determine the range of the data. The smallest measurement is 3.4 inches and the largest is 5.4 inches, so the range is 5.4 - 3.4 = 2 inches. To create 6 classes with a width of 0.4 inches, we divide the range by 0.4 and round up to the nearest integer:
Number of classes = (range / class width) rounded up = 2 / 0.4 = 5
So we will use 5 classes with a width of 0.4 inches each. The classes and their corresponding frequency counts are:
Class 1: 3.4 - 3.8 | Frequency: 3
Class 2: 3.9 - 4.3 | Frequency: 8
Class 3: 4.4 - 4.8 | Frequency: 6
Class 4: 4.9 - 5.3 | Frequency: 7
Class 5: 5.4 - 5.8 | Frequency: 1
To create a histogram, we can plot the frequency counts on the y-axis and the class intervals on the x-axis. The shape of the histogram can give us information about the distribution of the data. In this case, the histogram is bimodal, meaning there are two peaks in the data. This suggests that the data may be composed of two separate subpopulations.

How to solve the problem?To solve this problem, we can use the Law of Sines, which states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all sides and angles in the triangle.
Let's label the missing side as b, and use sin(A) = opposite/hypotenuse to find the length of the side opposite angle A:
sin(A) = opposite/hypotenuse
sin(33.7°) = b/8
b = 8 × sin(33.7°)
b ≈ 4.726

Solve for ∠A
. Round your answer to the nearest tenth.
∠A
= degrees
(60 points)
Answer:
∠A = 48.2
Step-by-step explanation:
Cos^-1(6/9
Use the Cosine with the negative one because you are finding an angle. Then, because Cosine is adjacent/hypotenuse, 6 would be your adjacent side length to theta and 9 would be the hypotenuse as it is across from the right angle.
Eric had a box of 24 candy bars that he planned to sell for 63 cents each. Unfortunately, his sister ate 7 of his candy bars before he started selling them. In order to bring in the same amount of money as he would have if his sister had not eaten any of the candy bars, what price (in cents) should he charge for each of the remaining candy bars?
The price (in cents) should he charge for each of the remaining candy bars 49
First, we would want to calculate how much the box would sell for before the sister ate some.
We would get 24*63(in cents) and we can further get 1512 cents before the sister ate the candy bars.
The sister ate 7 candy bars leaving us with 31 candy bars. To deduct the price for each candy bar, it would be a situation like the following:
$6 for 3 boxes of 500 cookies (i know that's cheap)
6/3...
$2 per box.
Using our situation we get 1512 cents for 31 candy bars.
1512÷31
=48.77
That does seem unrealistic, so we round to the nearest whole number and we get...
49 cents

In ΔMNO, m ∠ � = ( 4 � − 13 ) ∘ m∠M=(4x−13) ∘ , m ∠ � = ( 2 � − 13 ) ∘ m∠N=(2x−13) ∘ , and m ∠ � = ( 5 � + 19 ) ∘ m∠O=(5x+19) ∘ . Find m ∠ � . m∠N.
The value of m∠N is 21° ,the value of m∠M is 55° and the value m∠O is 106°.
To find the value of x, we can use the fact that the sum of the angles in a triangle is 180 degrees. Therefore:
m∠M + m∠N + m∠O = 180
Substituting the given angle measures, we get:
(4x-13) + (2x-13) + (5x+19) = 180
Simplifying the equation, we get:
11x - 7 = 180
11x = 187
x = 17
Now that we know the value of x, we can find the measure of each angle. Substituting x = 17, we get:
m∠M = (4x-13) = (417-13) = 59 degrees
m∠N = (2x-13) = (217-13) = 21 degrees
m∠O = (5x+19) = (5*17+19) = 106 degrees
Therefore, the measure of ∠MNO is:
m∠N = 21 degrees
Note: The question also asks for the measure of ∠P, but there is no information given about ∠P in the problem.

One plumbing job requires 45 meters of PVC pipe, and a second job requires 30 meters. The pipe comes in 6-meter lengths only. How many sections should the plumber buy? How much pipe will be left over, assuming that there are no errors?
a) The plumber should buy 13 sections of 6-meter lengths of PVC pipes.
b) Assuming that there are no errors, the left-over pipe after satisfying Jobs A and B should be 3 meters.
How the quantities are determined:We can use mathematical operations of addition, division, multiplication, and subtraction to determine the two quantities above.
In the first place, the total quantity of PVC pipes required is 75 meters.
This sum is divided by 6 to obtain the sections required, which is approximated to the nearest whole number.
Finally, 75 meters are subtracted from the total quantity bought.
PVC pipes required by Job A = 45 meters
PVC pipes required by Job B = 30 meters
The total quantity of PVC pipes required = 75 meters
The length of each PVC pipe = 6 meters
The number of pipes to buy = 13 sections (75 ÷ 6)
13 sections of pipes = 78 (6 x 13)
Leftover PVC pipes = 3 meters (78 - 75)
