For the statement below, write the claim as a mathematical statement. State the null and alternative hypotheses and identify which represents the claim.
An amusement park claims that the mean daily attendence at the park is people.
Mathematical statement μ = 18000 where μ is the mean, Null hypothesis H₀ : μ = 18000, Alternate hypothesis Hₐ : μ ≠ 18000.
What does a mathematical statement mean to you ?A mathematical statement is a meaningful string of words that can be either true or false.
For instance , 3+4=7 is always true. Consequently, it is a true statement.
Similar to this , 3+4=8 is never true Therefore, it is a false statement.
Here the amusement park makes the claim that the mean daily attendence at the park is 18000 people
∴ μ = 18000 is the statement .
What is a null hypothesis ?A null hypothesis is known as statistical hypothesis that proposes that no statistical significance exists in a set of given observations. Hypothesis testing is used to assess the credibility of a hypothesis by using sample data. Sometimes referred to simply as the "null," it is represented as H₀.
∴ Here the null hypothesis is μ = 18000
What do you understand by alternate hypothesis ?The alternative hypothesis is an assertion used in statistical inference experiment. It is contradictory to the null hypothesis and indicated by Ha or H₁ . We can also say that it is simply an alternative to the null. In hypothesis testing, an alternative theory is a statement which a researcher is testing.
For instance : A school principal claims that students in her school score an average of seven out of 10 in exams. The alternate hypothesis is μ ≠ 7.0.
Similarly here in this question alternate hypotesis will be μ ≠ 18000.

Use slopes and y-intercepts to determine if the lines 15x−6y=−5 and 5x−2y=5 are parallel.
The two lines are parallel because they have thesame slope and different y intercept
How do we know parallel lines?If two non-vertical lines that are in the same plane has the same slope. However the lines will have different y intercept.
A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.
Therefore putting the equations 15x−6y=−5 and 5x−2y=5 into that form.
15x-6y = -5
-6y = -15x-5
y = 5x/2 +5/6
for the second equation,
5x-2y =5
-2y = -5x-5

In the diagram below DE is parallel to XY what is the value of X
Since this is about the angle theorem and the angle theorem is a theorem that helps us know the relationship between angles. Being a corresponding angle, x = 105°. Hence option A is correct.
What are corresponding angles?A corresponding angle is an angle that occupies the same relative position as another angle elsewhere in the diagram. The corresponding angle in planar geometry occurs when a transverse line crosses his two straight lines. Two angles correspond or relate to each other by being on the same side of the horizontal line. One is the exterior angle (outside the parallel lines) and the other is the interior angle (inside the parallel lines).
You can see that the transversal line intersects two parallel lines DE and XY. From the transversal theorem of angles in mathematics, we know that when a transversal line intersects two parallel lines, the corresponding angles formed are congruent and therefore equal to each other.
In this question we see that one of the angles is 105°. Therefore x° is congruent to it, x = 105°.

B. $462.91
C. $454.31
D. $52.00
Answer:
Therefore, Frank's monthly credit card payment will be $454.31.
Step-by-step explanation:
Monthly payment = (PV * r) / (1 - (1 + r)^-n)
PV = $2,500 + $1,000 + $3,000 + $1,500
= $8,000
r = 0.18 / 12

You need to cut the strongest beam out of a log with a diameter of 18 in. The strength of a wooden beam is directly proportional to the product of its width and the square of its height. What are the dimensions of the strongest beam? Find the exact value and then round your answer to the nearest hundredth.
Need answers ASAP
The dimensions of the strongest beam are 27 inches x 13.5 inches.
What is a dimension?In general, dimension refers to a measurable extent of a physical quantity, such as length, width, height, depth, or time. These dimensions provide a framework for describing and measuring objects and events in the physical world. In geometry, dimension are refers to the number of coordinates needed to specify a point in a space. In physics, the concept of dimension is used to describe the properties of space and time.
We know that the strength of the beam is directly proportional to its width multiplied with the square of its height. Let's call the width of the beam "w" and the height "h". Then we can write the strength of the beam as:
S = kwh², where "k" is the constant of proportionality.
We want to find the dimensions of the strongest beam, which means we want to find the values of "w" and "h" that will maximize the strength "S". To do this, we need to find the maximum value of the function S = kwh² subject to the constraint that the diameter of the log is 18 inches.
The diameter of the log is equal to the width of the beam plus twice the height of the beam:
d = w + 2h
Since the diameter of the log is 18 inches, we can write:
w + 2h = 18
or
w = 18 - 2h
Substituting this expression for "w" into the equation for the strength of the beam, we get:
S = k × w(18-2h) × h²
Expanding and simplifying this expression, we get:
S = 36kh³ - 2kh⁴
To find the maximum value of S, we take the derivative of S with respect to h and set it equal to zero:
dS/dh = 108kh² - 8kh³ = 0
Simplifying this expression, we get:
h²(108 - 8h) = 0
This equation has two solutions: h = 0 and h = 13.5.
Since a beam with height equal to zero would have zero strength, we reject the solution h = 0. Therefore, the maximum strength is achieved when h = 13.5 inches.
To find the corresponding width, we can use the equation we derived earlier:
w = 18 - 2h = 18 - 27 = -9
Since the width of the beam cannot be negative, we reject this solution as well.
Therefore, the required dimensions of the strongest beam are:
Width = 2h = 2(13.5) = 27 inches
Height = h = 13.5 inches

Can you prove this trigonometric identity?
tan1/2x(2cotx+tan1/2x)=1
The trigonometric identity has been proven as 1 in the space below
How to prove the identityGiven the identity:
tan(1/2x) (2cot(x) + tan(1/2x)) = 1
To prove this identity, let's start by expressing cot(x) in terms of tan(x):
cot(x) = 1 / tan(x)
Now, replace cot(x) in the given identity:
tan(1/2x) (2(1/tan(x)) + tan(1/2x)) = 1
Now, let's use the double angle formula for tan(x):
tan(x) = 2 * tan(1/2x) / (1 - tan^2(1/2x))
Replace tan(x) in the equation:
tan(1/2x) (2(1/(2 * tan(1/2x) / (1 - tan^2(1/2x))) + tan(1/2x)) = 1
Simplify the equation:
tan(1/2x) ((1 - tan^2(1/2x)) + tan(1/2x) * tan(1/2x)) = 1
Now, notice that the expression in the parentheses is equal to 1:
(1 - tan^2(1/2x)) + tan^2(1/2x) = 1
So, we can simplify the equation further:
tan(1/2x) * 1 = 1
This directly leads us to the original identity:
tan(1/2x) = 1

ABC is a right angled triangle. if B = 90°, AC = 96 cm, C = 30°. Find AB?
Answer:
We can use trigonometry to find AB.
First, we can use the fact that the sum of the angles in a triangle is 180° to find angle A:
A + B + C = 180°
A + 90° + 30° = 180°
A = 60°
Now, we can use the sine function to find AB:
sin A = opposite/hypotenuse
sin 60° = AB/96
AB = 96 * sin 60°
AB = 96 * √3/2
AB = 48√3
Therefore, AB is approximately 83.14 cm (rounded to two decimal places).

A P=(2xl) + (2xw)
B V=SxSxS
C P= 4xs
D A= SXS
Answer:
D. A = s × s
Step-by-step explanation:
D. A = s × s is an area formula. Area is side times side. This is an area formula for a square. The units of area are square units. Since Jennifer has square inches in her answer, she was working on an area problem.
A. and C. are perimeter formulas. Perimeter is the distance around the outside of a shape. The units of perimeter are straight up plain, one-dimensional units like inches (or feet, meters, miles, km)
B. is a volume formula. The units of volume is cubic units or units to the third power.
The answer is D.
At the school's holiday craft fair, Colette and her classmates get to make gingerbread houses. Their teacher divides a bag of licorice ropes evenly among the 9 students at the table. Each student gets 3 licorice ropes to decorate the roof of his or her gingerbread house.
Answer: So, what are you asking?
Step-by-step explanation:
When Joann and Shana were counting the amount of money they had in their wallets, the total was at least$56 and at most $85. If Shana has only in her wallet, which of the following inequalities represents all possible values for the amount of money, j, that Joann has?
The inequality that represents all possible values for the amount of money that Joann has is 21 ≤ J ≤ 50.
What inequalities represents values for the amount of money that Joann has?Let's call the amount of money that Joann has in her wallet "J" and the amount of money that Shana has in her wallet "S".
We know that the total amount of money they have is at least $56 and at most $85. Therefore, we can write two inequalities:
J + S ≥ 56 (the total is at least $56)
J + S ≤ 85 (the total is at most $85)
We also know that Shana has only $35 in her wallet. We can substitute this value for S in the inequalities to get an inequality that represents all possible values for the amount of money that Joann has:
J + $35 ≥ 56 (substituting S = $35 in the first inequality)
J + $35 ≤ 85 (substituting S = $35 in the second inequality)
Simplifying these inequalities by subtracting $35 from both sides, we get:
J ≥ 21 (the amount of money Joann has is at least $21)
J ≤ 50 (the amount of money Joann has is at most $50).
