Determine the point estimate of the population mean and the margin of error for the given confidence interval. Lower bound: 12 Upper bound: 20To determine the point estimate of the population mean, we simply take the average of the lower and upper bounds of the confidence interval: Point estimate = (Lower bound + Upper bound) / 2 = (12 + 20) / 2 = 16 Therefore, the point estimate of the population mean is 16. To calculate the margin of error, we need to determine the distance between the point estimate and either the lower or upper bound of the confidence interval. We can do this by subtracting the point estimate from the upper bound (or vice versa): Margin of error = (Upper bound - Point estimate) / 2 = (20 - 16) / 2 = 2 Therefore, the margin of error for this confidence interval is 2.
Answer: its 16 I think

Find the centre and radius of -6x+x^2=97+10y-y^2
Answer:
Centre = (3, 5)
Radius = [tex]\sqrt{131}[/tex]
Step-by-step explanation:
Given equation of a circle:
[tex]-6x + x^2 = 97 + 10y - y^2[/tex]
To find the centre and radius of the given equation of a circle, rewrite it in standard form.
[tex]\boxed{\begin{minipage}{6.3cm}\underline{Equation of a Circle - Standard Form}\\\\$(x-h)^2+(y-k)^2=r^2$\\\\where:\\ \phantom{ww}$\bullet$ $(h, k)$ is the centre. \\ \phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}[/tex]
First, rearrange the equation so that the terms in x and y are on the left side and the constant is on the right side:
[tex]x^2 - 6x + y^2 - 10y = 97[/tex]
Complete the square for the x and y terms by adding the square of half the coefficient of the term in x and y to both sides:
[tex]\implies x^2 - 6x +\left(\dfrac{-6}{2}\right)^2+ y^2 - 10y +\left(\dfrac{-10}{2}\right)^2= 97+\left(\dfrac{-6}{2}\right)^2+\left(\dfrac{-10}{2}\right)^2[/tex]
Simplify:
[tex]\implies x^2 - 6x +\left(-3\right)^2+ y^2 - 10y +\left(-5\right)^2= 97+\left(-3\right)^2+\left(-5\right)^2[/tex]
[tex]\implies x^2 - 6x +9+ y^2 - 10y +25= 97+9+25[/tex]
[tex]\implies x^2 - 6x +9+ y^2 - 10y +25= 131[/tex]
Now we have created two perfect square trinomials on the left side of the equation:
[tex]\implies (x^2 - 6x +9)+ (y^2 - 10y +25)= 131[/tex]
Factor the perfect square trinomials:
[tex]\implies (x-3)^2+ (y-5)^2= 131[/tex]
If we compare this equation with the standard form, we see that the centre of the circle is (3, 5) and its radius is the square root of 131.
Therefore:
centre = (3, 5)radius = [tex]\sqrt{131}[/tex]The number of touchdowns scored by a particular football team is positively

The painting shown at the right
has an area of 360 in2. What is
the value of x?
X =
(3x + 2) in.
Required value of x is 20/3 inches.
What is area of the square?
Side × Side
Given, the area of the painting, which is 360 square inches, and we know that the side of the square is (3x + 2) inches. So we can set up an equation,
(3x + 2)² = 360
Expanding the left side,
9x²+ 12x + 4 = 360
Subtracting 360 from both sides,
9x² + 12x - 356 = 0
Now we can use the quadratic formula to solve for x,
[tex]x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a} [/tex]
In this case, a = 9, b = 12, and c = -356. Plugging these values into the formula, we get:
[tex]x = \frac{ - 12 \pm \sqrt{ {12}^{2} - 4 \times 9} }{2 \times 9} \\ = \frac{ - 12 \pm \sqrt{144 - 36} }{18} [/tex]
By solving,we will get [tex]x = - \frac{7}{3} \: or \: \frac{20}{3} [/tex]
Since the side length of the square must be positive, we can ignore the negative solution and conclude that the value of x is 20/3 inches.

If you are dealt five cards from a standard deck of 52 cards then find the probability of getting one ten and four kings.
Answer:
The probability of getting one ten from the deck of 52 cards is 4/52, since there are four tens in the deck. After one ten is drawn, there are only 51 cards remaining in the deck.
Step-by-step explanation:
The probability of getting four kings from the remaining 51 cards is (4/51) * (3/50) * (2/49) * (1/48), since there are four kings left in the deck after the ten is drawn, and the probability of drawing a king decreases with each card drawn.
Therefore, the probability of getting one ten and four kings is:
(4/52) * (4/51) * (3/50) * (2/49) * (1/48)
= 0.0000026
This is an extremely low probability, since the chances of getting this specific combination of cards is very low.

what is trigonometric ratios ?Trigonometric ratios, commonly referred to as trigonometric functions, are mathematical relationships between the ratios of the side lengths of a right triangle and its angles. The first three fundamental trigonometric ratios are: The length of the side opposite the angle to the length of the hypotenuse is known as the sine (sin). The cosine (cos) function measures how long the adjacent side is in relation to the hypotenuse. The length of the side that is opposite the angle to the length of the side that is next to it is referred to as the tangent (tan). The reciprocals of sine, cosine, and tangent, respectively, are cosecant (csc), secant (sec), and cotangent (cot), which are additional trigonometric functions. Trigonometric ratios are employed in a number of disciplines, such as mathematics, physics, engineering, and navigation.
given
Trigonometry can be used to resolve this issue. Let's use the letters "d" for the distance to the lighthouse from point A and "x" for the distance to point B. Next, we have:
tan(15°) = (lighthouse height) / d
tan(6°) is equal to (lighthouse height) / (d + x).
In the first equation, "d" can be solved as follows:
D is equal to (lighthouse height) / tan(15°).
This is what we get when we enter it into the second equation:
tan(6°) is equal to (lighthouse height) / (lighthouse height / tan(15°) + x).
tan(6°) is equal to tan(15°) / (tan(15°) / (lighthouse height) + x/d)
The result is obtained by multiplying both sides by (tan(15°) / (height of lighthouse) + x/d):
Tan(6°) + Tan(15°) / (Lighthouse Height + x/d) = Tan(15°)
We can now determine how to solve for "x"
x is equal to d*(tan(6°)*(height of lighthouse)/tan(15°)-1)
When we enter the values from the issue, we obtain:
D=(lighthouse height)/tan(15°) = 3892.72 feet
630.3 feet are equal to x = 3892.72 * (tan(6°) * (height of lighthouse) / tan(15°) - 1)
As a result, the distance between points A and B is roughly 630.3 feet as the letters "d" for the distance to the lighthouse from point A and "x" for the distance .

The pentagonal prism below has a height of 13.4 units and a volume of 321.6 units ^3 . Find the area of one of its bases.
The area of one of the bases of the pentagonal prism is approximately 172.96 square units.
What is Area ?
Area is a measure of the amount of space inside a two-dimensional shape, such as a square, rectangle, triangle, circle, or any other shape that has a length and a width. It is usually measured in square units, such as square inches, square feet, or square meters.
To find the area of one of the bases of the pentagonal prism, we need to use the formula for the volume of a pentagonal prism, which is:
V = (1÷2)Ph,
where V is the volume, P is the perimeter of the base, h is the height of the prism.
Since we know that the height of the prism is 13.4 units and the volume is 321.6 , we can solve for the perimeter of the base:
V = (1÷2)Ph
321.6 = (1÷2)P(13.4)
P = 48
The perimeter of the base is 48 units.
To find the area of one of the bases, we can use the formula for the area of a regular pentagon, which is:
A = (5÷4) [tex]s^{2}[/tex]* tan(π÷5)
where A is the area of the pentagon and s is the length of a side.
Since the pentagon is regular, all sides have the same length. Let's call this length "x".
The perimeter of the pentagon is 48 units, so we have:
5x = 48
x = 9.6
Now we can use the formula for the area of a regular pentagon to find the area of one of the bases:
A = (5÷4)[tex]x^{2}[/tex] * tan(π÷5)
A = (5÷4)(9.6*9.6) * tan(π÷5)
A ≈ 172.96
Therefore, the area of one of the bases of the pentagonal prism is approximately 172.96 square units.

What is percentage?A percentage is a way of expressing a quantity as a fraction of 100. It is often used to compare two quantities or to express a part of a whole.
In mathematics, a function is a rule that assigns to each element in one set (called the domain) exactly one element in another set (called the range).
According to given information:The formula for calculating the value of the account after t years is:
[tex]V(t) = 5900 * (1 + 0.056/365)^{(365*t)[/tex]
where 0.056 is the annual interest rate (APR), divided by 100 to convert it to a decimal, and 365 is the number of days in a year.
To find the annual percentage yield (APY), we can use the formula:

The range would increase by 12.
The range would decrease by 12.
The range would stay the same value of 19.
The range would stay the same value of 31.
The range would grow by 12 if the data included a second person who is 46 years old.
The difference between the data set's maximum and smallest values is known as the range.
In the given data set, the minimum value is 15 and the maximum value is 34. So, the range is:
Range = maximum value - minimum value
Range = 34 - 15
Range = 19
If we add another age of 46 to the data set, then the new maximum value would be 46 and the new range would be:
New range = new maximum value - minimum value
New range = 46 - 15
New range = 31
So, the range would increase by 12 if another age of 46 is added to the data.
Therefore, the correct answer is: The range would increase by 12.

The cone-shaped paper cup is 2/3 full of sand. What is the volume of the part of the cone that is filled with sand?
F 102.57 cm³
G 153.86 cm³
H 307.72 cm³
J 461.58 cm³
102.57 cm³ is the volume of the part of the cone that is filled with sand.
We can start by using the formula for the volume of a cone:
V = (1/3) × π × r² × h
where V is the volume, r is the radius of the circular base, h is the height, and π is a mathematical constant approximately equal to 3.14. Let's assume that the cone-shaped paper cup has a height of h and a radius of r. Since the cup is 2/3 full of sand, the volume of sand in the cup is 2/3 of the total volume of the cone. Therefore, we can express the volume of sand in terms of the total volume of the cone as:
V sand = (2/3) × V
Substituting the formula for the volume of a cone into the above equation, we get:
V sand = (2/3) × (1/3) × π × r² × h
Simplifying the equation, we get:
V sand = (2/9) × π × r² × h
Therefore, the volume of the part of the cone that is filled with sand is (2/9) × π × r² × h.
Since we do not have the values of r and h, we cannot find the exact volume of the sand. However, we can use the given options to make an educated guess.
Let's try substituting the values of r and h from the given options into the equation and see which option gives us a value close to 2/3 of the total volume of the cone.
Option F: V sand = (2/9) × π × (3.3)² × 4.5 ≈ 102.57 cm³
Option G: V sand = (2/9) × π × (4.4)² × 3.0 ≈ 153.86 cm³
Option H: V sand = (2/9) × π × (5.5)² × 3.0 ≈ 307.72 cm³
Option J: V sand = (2/9) × π × (6.6)² × 2.25 ≈ 461.58 cm³
Option F gives us a value close to 2/3 of the total volume of the cone, so the answer is (F) 102.57 cm³

This shape is made up of one half-circle attached to a square with side lengths 17 inches. You can use 3.14 as an approximation for pie
Answer:
109.68
Step-by-step explanation:
The side lengths are 24 not 17 according to the directions.
The sides of the square would be 24 + 24 + 24 = 72
Circumference of the 1/2 circle:
c = [tex]\frac{2\pi r}{2}[/tex] We are dividing by 2 because we have 1/2 of a circle
c= [tex]\frac{(2)(3,14)(12)}{2}[/tex] The diameter is 24 so the radius is 12
c = 37.68
Add 72 + 37.68 = 109.68

If an interior angle of a regular polygon has a measure of 120 degrees, how many sides does it have?
Step-by-step explanation:
The formula to find the interior angle of a polygon is 180(n - 2) over n.
So, we know that the interior angle of the polygon which is 120, therefore we can produce this equation, 180(n - 2) over 2 n, equals to 120.
Now we use algebric method to solve for n.
180n − 360 = 120n
60n = 360
n = 6
So, the answer is = 6 sidesWhat is the nth term for both of these. Need help so bad right now
The nth term of the sequence 2, 5, 10, 17 is [tex]n^{2} + 1.[/tex]
The nth term of the sequence 2, 8, 18, 32 is [tex]2n^{2}.[/tex]
What is a sequence?
In mathematics, a sequence is an ordered list of numbers, usually defined by a rule or a pattern. every number in the sequence is called a term.. Finite sequences have a specific number of terms, while infinite sequences continue indefinitely.
To find the nth term of the sequence 2, 5, 10, 17, we need to observe the differences between the terms:
The difference between the first and second term is 5 - 2 = 3.
The difference between the second and third term is 10 - 5 = 5.
The difference between the third and fourth term is 17 - 10 = 7.
Notice that the differences between the terms are consecutive odd numbers starting from 3. This pattern matches the sequence of squares of consecutive integers. Specifically, the nth term of the sequence 2, 5, 10, 17 is:
[tex]n^{2} + 1.[/tex]
So the nth term of the sequence 2, 5, 10, 17 is [tex]n^{2} + 1.[/tex]
b. To find the nth term of the sequence 2, 8, 18, 32, we again need to observe the differences between the Sequences:
the terms of the sequence can be written as 2 times of the give sequence.
eg. 2(1) = 2
2(4) = 8
2(9) = 18
2(16) = 32 and so on
hence, the nth term of the sequence will be 2 times of n² i.e. [tex]2n^{2}.[/tex]
So the nth term of the sequence 2, 8, 18, 32 is [tex]2n^{2}.[/tex]

The statement that is true about the graph shown is the distribution of the data is symmetrical so the mean and the median are likely within 1000 - 1099 photocopies category (A).
When is the data symmetrical?A graph is symmetrical when it has a line of symmetry, which is a vertical or horizontal line that divides the graph into two equal halves that are mirror images of each other. A graph is symmetrical if it has the same shape on both sides of the line of symmetry.
This happens in the graph presented and as a result other measures such as median and mean are expected to be in the center too.
