the answer will be 3675.0 m (rounded to one decimal place)
What is rounded off?
Rounding off is a process of approximating a number to a certain degree of accuracy. When we round off a number, we usually need to specify the number of digits we want to keep or the position to which we want to round.
For example, if we want to round off 3.14159 to two decimal places, we would look at the third decimal place (which is 1) and see that it is less than 5, so we would keep the first two decimal places and round off the rest. Thus, rounding off 3.14159 to two decimal places would give us 3.14.
Rounding off is often used to simplify numbers or make them easier to work with, especially in situations where exact values are not necessary or practical.
To round 3675 m to the nearest tenth of a meter, we need to look at the hundredth digit, which is 7. Since 7 is greater than or equal to 5, we need to round up the last digit (tenth digit). Therefore, rounding 3675 m to the nearest tenth of a meter gives us:
Hence the answer will be 3675.0 m (rounded to one decimal place).

Describe Triangles?A triangle is a geometric figure that is formed by three line segments joining three non-collinear points in a plane. It is a three-sided polygon and the most basic two-dimensional shape. A triangle has three interior angles and three vertices. The sum of the interior angles of a triangle is always 180 degrees, and each angle is measured in degrees. Triangles can be classified based on the length of their sides and the measures of their angles. There are several types of triangles such as equilateral, isosceles, scalene, acute, right, and obtuse triangles. Triangles are used in various fields such as engineering, architecture, mathematics, and physics, and they are an essential part of many geometric calculations and constructions.
To solve this problem, we can use the angle bisector theorem which states that if a line bisects an angle of a triangle, then it divides the opposite side into two segments that are proportional to the adjacent sides.
Let AD = x. Then we can set up the following proportion:
AC/CD = AB/BD
Substituting the given values, we get:
24/x = 15/(18 - x)
Simplifying this equation, we get:
360 - 15x = 24x
39x = 360
x = 9.23 (rounded to the nearest tenth)
Therefore, the length of AD is approximately 9.2 units.

What is a reflection over the x-axis?In Mathematics and Geometry, a reflection over the x-axis is represented by this transformation rule (x, y) → (x, -y). Therefore, a reflection over or across the x-axis would maintain the same x-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.
For a reflection over the x-axis, the new coordinates of A is given by:
(x, y) → (x, -y)
A (2, 4) → (2, -(4)) = B (2, -4)
For a reflection over the y-axis, the new coordinates of A is given by:

Paisley invested $16,000 in an account paying an interest rate of 8 3/8% compounded
monthly. Jayden invested $16,000 in an account paying an interest rate of 8 5/8%
compounded annually. To the nearest dollar, how much money would Paisley have
in her account when Jayden's money has tripled in value?
Paisley would have about $48147 in her account when Jayden's money has tripled using compounding.
What is compounding ?
In mathematics, compounding refers to the process of adding interest to an investment or loan, such that the interest is earned on both the principal amount and any previously accumulated interest.
First, let's find out how many years it will take for Jayden's money to triple in value. We can use the formula for compound interest:
[tex]A = P(1 + r/n)^{(nt)[/tex]
where:
A = final amount
P = principal (starting amount)
r = interest rate (as a decimal)
n = number of times compounded per year
t = number of years
For Jayden, P = $16,000, r = 8.625% = 0.08625, n = 1 (compounded annually), and we want to find t when A = 3P = $48,000. Plugging in these values, we get:
[tex]\$48,000 = \$16,000(1 + 0.08625/1)^{(1t)[/tex]
[tex]3 = 1.08625^t[/tex]
[tex]ln(3) = t*ln(1.08625)[/tex]
[tex]t = ln(3) / ln(1.08625)[/tex]
t ≈ 13.2 years
So it will take about 13.2 years for Jayden's money to triple in value.
Next, let's find out how much Paisley will have in her account after the same amount of time, using the formula:
[tex]A = P(1 + r/n)^{(nt)[/tex]
For Paisley, P = $16,000, r = 8.375% = 0.08375, and n = 12 (compounded monthly). Plugging in t = 13.2 years, we get:
[tex]A = \$16000*(1 + 0.08375/12)^{(12*13.2)[/tex]
A ≈ $48147
Therefore, Paisley would have about $48147 in her account when Jayden's money has tripled in value, to the nearest dollar.

what is the probability that from a sample of 30 indianapolis residents, fewer than 95% were rooting for the giants in super bowl xlvi?
The probability that from a sample of 30 Indianapolis residents, fewer than 95% were rooting for the Giants in Super Bowl XLVI is approximately 0.304.
This problem can be solved using the binomial distribution, which models the probability of a certain number of successes in a fixed number of independent trials, each with the same probability of success.
Let X be the number of Indianapolis residents in a sample of 30 who wanted the Giants to beat the Patriots. Then X follows a binomial distribution with n = 30 and p = 0.97, since the probability of success (rooting for the Giants) is 0.97 for each resident.
We want to find the probability that fewer than 95% of the sample wanted the Giants to win. That is, we want to find P(X < 0.95*30) = P(X < 28.5), where X has the binomial distribution with parameters n = 30 and p = 0.97.
We can use a continuity correction and approximate this probability by the cumulative distribution function of a normal distribution with mean np and variance np(1-p). That is,
P(X < 28.5) ≈ P(Z < (28.5 - np) / sqrt(np(1-p)))
where Z is a standard normal random variable. Substituting the values of n and p, we get
P(X < 28.5) ≈ P(Z < (28.5 - 300.97) / sqrt(300.97*0.03))
≈ P(Z < -0.51)
Using a standard normal table or calculator, we find that P(Z < -0.51) ≈ 0.304. Therefore, the probability that fewer than 95% of the sample wanted the Giants to win is approximately 0.304.

Which angle measures are correct? select three options. m∠x = 55° m∠w = 125° m∠w = 55° m∠z = 125° m∠z = 55°
The correct angle measures of triangle XWZ are m∠x = 55°, m∠w = 125°, m∠z = 125°. The correct options are A, B and D.
The correct angle measures are m∠x = 55°, m∠w = 125°, m∠z = 125°
The option "m∠w = 55°" and "m∠z = 55°" are incorrect. Because "m∠w = 55°" and "m∠z = 55°" are incorrect is that there is only one angle measurement that can be equal to 55°, which is m∠x. This is because in any triangle, the sum of the interior angles is always 180°. Therefore, if m∠x is 55°, then the sum of the other two angles (m∠w and m∠z) must add up to 125° (i.e., 180° - 55°).
So, if m∠w is 125°, then m∠z must also be 55°, and if m∠z is 125°, then m∠w must be 55°. Hence, the options "m∠w = 55°" and "m∠z = 55°" cannot both be correct at the same time. So, the correct answers are A, B and D.

Belle bought 40 pairs of trousers for $2040. She sold them all at the same selling price and made a loss of $200.
(i) How much did each pair of trousers cost Belle to buy?
(ii) How much loss did she make on each pair of trousers?
(iii) What was the selling price of each pair?
Answer:
Let the cost of each pair of trousers be x dollars.
(i) Belle bought 40 pairs of trousers for a total of $2040, so we can set up an equation:
40x = 2040
Solving for x, we get:
x = 2040/40 = 51
Therefore, each pair of trousers cost Belle $51 to buy.
(ii) Belle made a loss of $200 on the entire sale of 40 pairs of trousers. The cost of 40 pairs of trousers is:
40 x $51 = $2040
So, Belle sold 40 pairs of trousers for:
$2040 - $200 = $1840
Belle's cost was $2040, and she sold the trousers for $1840, so her loss was:
$2040 - $1840 = $200
The loss per pair of trousers is the total loss divided by the number of pairs of trousers sold, which is:
$200/40 = $5
Therefore, Belle made a loss of $5 on each pair of trousers sold.
(iii) The selling price of each pair of trousers can be found by adding the loss per pair to the cost per pair:
Selling price = Cost + Loss
Selling price = $51 + $5
Selling price = $56
Therefore, Belle sold each pair of trousers for $56.

The sampling variability can be reduced by increasing the sample size. Hence, it is essential to ensure that a large enough sample size is used to obtain reliable estimates of population parameters.
Parameter and statistic: Parameter is a value that describes the population, while statistic is a value that describes a sample.
Parameters are usually represented using Greek letters, while statistics are usually represented using Roman letters. In other words, a parameter is a population characteristic, whereas a statistic is a sample characteristic.
P and p hat: P represents the true proportion of a population with a particular attribute, while p hat represents the proportion of a sample with that attribute. P hat is an estimate of the true proportion p, which may differ from the actual proportion due to sampling error.
Sampling variability: Sampling variability is the variation in sample statistics that occurs from sample to sample. It is the result of the fact that different samples of the same size drawn from the same population will produce different estimates of the population parameter due to random sampling error. The sampling variability can be reduced by increasing the sample size. Hence, it is essential to ensure that a large enough sample size is used to obtain reliable estimates of population parameters.

Using the interquartile range (IQR) method, the value 2 is considered an outlier in the given data.
To determine if there is an outlier in the given data, we need to calculate the lower and upper bounds using the interquartile range (IQR) method.
First, we need to calculate the first quartile (Q1), second quartile (Q2 or median), and third quartile (Q3) of the data.
Arranging the data in ascending order
2, 9, 13, 17, 18, 20, 23, 24, 33, 34, 43, 45, 53, 53
Q1 = 17
Q2 = 24
Q3 = 43
Next, we can calculate the IQR by subtracting Q1 from Q3
IQR = Q3 - Q1 = 43 - 17 = 26
Now we can calculate the lower and upper bounds
Lower bound = Q1 - 1.5 × IQR = 17 - 1.5 × 26 = -8
Upper bound = Q3 + 1.5 × IQR = 43 + 1.5 × 26 = 79
Any values outside the lower and upper bounds are considered outliers.
In this case, we have a value of 2 that is outside the lower bound of -8. Therefore, 2 is considered an outlier in the given data.

Elijah is selling long sleeve t-shirts ( x ) and short sleeve t-shirts ( y ) for his family reunion in Charleston. The long sleeve t-shirts cost $27 each and the short sleeve t-shirts cost $20 each. Elijah collected $543 for all the t-shirts he sold. If Elijah sold 15 short sleeve t-shirts, how many long sleeve t-shirts did he sell? Write an equation to model the situation: x + y = How many long sleeve t-shirts did Elijah sell?
Answer: 9
Step-by-step explanation:
Let's first represent the given information in the form of an equation. We know that the long sleeve t-shirts (x) cost $27 each, and the short sleeve t-shirts (y) cost $20 each. Elijah collected $543 in total. So we can write the equation as:
27x + 20y = 543
We also know that Elijah sold 15 short sleeve t-shirts (y), so we can plug that value into the equation:
27x + 20(15) = 543
Now, we solve for x:
27x + 300 = 543
Subtract 300 from both sides of the equation:
27x = 243
Now, divide by 27:
x = 9
So Elijah sold 9 long sleeve t-shirts.
Number of long sleeve t shirts that Elijah sell is 9 long sleeve t shirts.
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Linear equations may include one or more variables.
Given that,
The long sleeve t-shirts cost $27 each and the short sleeve t-shirts cost $20 each.
He collected a total of $543.
So, we get an equation,
27x + 20y = 543
Also, given that, Elijah sold 15 short sleeve t-shirts.
Substitute y = 15.
27x + (20 × 15) = 543
27x + 300 = 543
27x = 543 - 300
27x = 243
x = 9
Hence Elijah sold 9 long sleeve t shirts.

Surface Area = 2(6.8)(1.6) + 2(6.8)(3.8) + 2(1.6)(3.8)
= 21.76 + 51.68 + 12.16
= 85.6
the surface area of the rectangular prism is 85.6 square units.
What is the factored form of x2 - 9x + 20?
A. x(x - 9) + 20
B. (x-4)(x + 5)
C. (x - 4)(x - 5)
D. (x2 - 4)(x2 - 5)
-------------------------------------------------------------------------------------------------------------
Answer: Option C, (x - 4)(x - 5)
-------------------------------------------------------------------------------------------------------------
Given: [tex]\textsf{x}^2\textsf{ - 9x + 20}[/tex]
Find: [tex]\textsf{Determine the factored form}[/tex]
Solution: In order to factor the given equation, we need to first determine two numbers which add up to -9 and multiply to become 20. We can think of the factors of 20 which would add up to -9 and the one that matches that description would be -5 and -4. These two numbers multiply to become 20 and combine to become -9. Now that we have that information, we can break up the quadratic into two separate roots using the two numbers that we found.
Therefore, the answer would be Option C, (x - 4)(x - 5).

10 years ago, a father is 8 times the age of his son. If the total of their ages now is 56, what are their present ages?
Answer: present age of father=42
present age of son=14
Step-by-step explanation:
let x=present age of father
56-x=present age of son
10 yrs ago:
x-10=age of father
56-x-10=46-x=age of son
age of father=8 times age of son
x-10=8(46-x)
x-10=368-8x
9x=378
x=42
56-x=14
present age of father=42
present age of son=14

The value of the angle a is 49 degrees and angle b is 139 degrees in the given triangle.
What are exterior angles?External angles are those that run parallel to a polygon's inner angles but are located outside of it. The sum of the two internal opposed angles determines the size of an outside angle. For each vertex, there are two equivalent exterior angles.
Each vertex typically displays a single external angle. The exterior angles of a triangle are those that are formed outside of it. The exterior angle of a triangle is defined as the angle formed between one of a triangle's sides and its neighboring extended side. As a result, the exterior angle of a triangle is the angle formed by any extended side of a triangle and its neighboring side.
Given that the measure of angle y = 49 degrees.
We observe from the figure that angle a is vertically opposite angle of y thus,
angle y = angle a = 49 degrees.
Now, angle b is exterior angle and,
angle b = angle a + 90
angle b = 49 + 90
angle b = 139 degrees.
Hence, the value of the angle a is 49 degrees and angle b is 139 degrees in the given triangle.

A soccer ball is made using a pattern of black pentagons and white
hexagons. What are the measures of the angles of the shapes that make the soccer ball? Explain. PLEASE HELP
Answer:
Each black pentagon in the soccer ball is surrounded by five white hexagons. Each white hexagon is, in turn, surrounded by three black pentagons and three other white hexagons. This pattern is repeated throughout the soccer ball.
To find the measures of the angles of the shapes that make the soccer ball, we need to first consider the angles of a regular pentagon and a regular hexagon.
A regular pentagon has five sides and five angles that are equal in measure. The formula for finding the measure of each angle in a regular pentagon is:
(angle measure) = (180(n-2))/n, where n is the number of sides.
In the case of a regular pentagon, n=5. Therefore, the measure of each angle in a regular pentagon is:
(angle measure) = (180(5-2))/5 = 108 degrees.
A regular hexagon has six sides and six angles that are equal in measure. The formula for finding the measure of each angle in a regular hexagon is:
(angle measure) = (180(n-2))/n, where n is the number of sides.
In the case of a regular hexagon, n=6. Therefore, the measure of each angle in a regular hexagon is:
(angle measure) = (180(6-2))/6 = 120 degrees.
Now, let's consider the angles of the shapes that make up the soccer ball.
Each black pentagon has five angles that are equal in measure. Therefore, each angle in a black pentagon measures:
(angle measure) = (180(5-2))/5 = 108 degrees.
Each white hexagon has six angles that are equal in measure. Therefore, each angle in a white hexagon measures:
(angle measure) = (180(6-2))/6 = 120 degrees.
