Using Euclid's Algorithm, the greatest common divisor or 8406 and 1242 is 18
The first number = 8406
The second number = 1242
We have to find the greatest common divisor of the given numbers 8406 and 1242 using the Euclid's Algorithm
8406 / 1242 = 6 R 954
8406 = 6 × 1242 + 954
1242 / 954 = 1 R 288
1242 = 1 × 954 + 288
954 / 288 = 3 R 90
954 = 3 × 288 + 90
288 / 90 = 3 R 18
288 = 3 × 19 + 18
90 / 18 = 5 R 0
90 = 5 × 18 + 0
The remainder became zero, so the greatest common divisor 18
Therefore, the greatest common divisor of 8406 and 1242 is 18

sides BC or DF.Given A(1,4), B(-2,5)and C(3, 4), which coordinate pair will make AB perpendicular to CD ?
The coordinate pair of D that will make AB perpendicular to CD is ( 4,7)
How are lines perpendicular in a coordinate?The slopes of perpendicular lines are opposite reciprocals of each other. Their product is -1.
The slope of a line is given as ( y1-y2)/(x1-x2)
for AB and CD to be perpendicular
( y2-y1)/(x2-x1) × ( y4-y3)/(x4-x3) = -1
therefore (5-4)/-2-1 = ( y4-y3)/(x4-x3)
1/-3 ×(y4-4)/(x4-3) = -1
(y4-4)/(x4-3) = 3/1
therefore 3= y4-4 and 1 = x4-3
therefore y4 = 3+4= 7
and x4 = 1+3= 4
therefore the coordinate of D = (x4,y4) for AB perpendicular to CD = (4,7)

sume of angles of a triangel greater than 180 degrees when teh triange is so large that it extends to cosmological scales
In hyperbolic geometry, the angle sum of a triangle is always less than 180 degrees.
A lune is a wedge of a sphere with angle θ, represented by L(θ) in the proof.
α, β, and γ are the three angles of the triangle.
4πr²+4area[αβγ]=2L(α)+2L(β)+2L(γ)
2(2πr²+2area[αβγ])=2(L(α)+L(β)+L(γ))
2πr²+2area[αβγ]=L(α)+L(β)+L(γ)
At this point, we need to use a theorem that states that a lune whose corner angle is θ radians has an area of 2θr².
2πr²+2area[αβγ]=2αr²+2βr²+2γr²
2πr²+2area[αβγ]=2r²(α+β+γ)
π+area[αβγ]r²=α+β+γ

Write an equation of a circle whose
center is (-1,3) and passes through the
point (7,-2).
Answer: (x + 1)^2 + (y - 3)^2 = 65
Step-by-step explanation:
Answer: (x+1)²+(y-3)²=89
Step-by-step explanation:
An equation of a circle: (x-a)²+(y-b)=R²
The center of a circle is (-1,3), hence a=-1 b=3
(x-(-1))²+(y-3)=R²
(x+1)²+(y-3)²=R² (1)
Substitute the coordinate (7,-2) belonging to the circle into equation (1):
(7+1)²+(-2-3)²=R²
8²+(-5)²=R²
64+25=R²
89=R²
Thus, R²=89
Hence,
(x+1)²+(y-3)²=89
an escalator has a slope of 3/4 after traveling forward 128 feet, the escalator is 96 feet above the floor. Write this word problem in point slope form
The point slope form of the slope of escalator and distance is y-24 = 3/4(x-32).
The general point slope form is given by the equation -
y - y1 = m (x - x1)
Now we are given the slope as 3/4. So, keeping the values of y1 and x1 in the equation. Let us assume the points as (32, 24). As per the points, 32 is x1 and 24 is y1.
y - 24 = 3/4(x - 32)
y - 24 = 3x/4 - 3/4×32
Performing division on Right Hand Side of the equation
y - 24 = 3x/4 - 3×8
y - 24 = 3x/4 - 24
Rewriting the equation
y - 3x/4 = - 24 + 24
Solving the equation on Right Hand Side of the equation
y - 3x/4 = 0
y = 3x/4
Thus, the equation is y - 24 = 3/4(x - 32).

Independent random samples, each containing 80 observations, were selected from two populations. The samples from populations 1 and 2 produced 33 and 28 successes, respectively.
Test H0:(p1−p2) = 0 against Ha:(p1−p2) ≠ 0. Use α = 0.05
The test statistic should be: _______
The P-value is _______
From two populations, independent random samples were drawn, each having 80 observations. The test statistic should be z = 2.18 because samples from populations 1 and 2 yielded 33 and 28 successes, respectively.
P-value is set at 0.030.
State the null and alternate hypotheses in step one.
H0: (p1-p2) = 0
Ha: (p1-p2) ≠ 0
Step 2: Calculate the test statistic
We can calculate the test statistic using the formula:
z = (p1-p2)/√(p(1−p)(1/n1+1/n2))
where,
p = (successes in sample 1 + successes in sample 2)/(n1+n2)
= (33 + 28)/(80 + 80)
= 61/160
= 0.30
n1 = sample size of population 1
= 80
n2 = sample size of population 2
= 80
Therefore,
z = (p1-p2)/√(p(1−p)(1/n1+1/n2))
= (33/80 - 28/80)/√(0.38125(1−0.38125)(1/80+1/80))

Assume that the game playthrough times for a newly released puzzle game has a mean of 49.8 minutes and a standard deviation of 4.2 minutes. A sample of size n39 playthrough times is randomly selected from a gaming population. What is the probability that the sample.mean is in between 50 minutes and 51 minutes? You may use a calculator or the portion of the z-table given below. Round your answers to three decimal places where appropriate
The probability that the sample mean is in between 50 minutes and 51 minutes is 0.345.
How to calculate probability?
n = sample size = 39
σ = standard deviation =4.2
μ = population mean = 49.8
Probability is the chance that an event can occur, in this case probability is used to measure the chance sample mean is between 50 minutes and 51 minutes. So,
P(50 ≤ x ≤ 51) = P([tex]\frac{\bar x-\mu}{\frac{\sigma}{\sqrt{n}}}[/tex] ≤ z ≤ [tex]\frac{\bar x-\mu}{\frac{\sigma}{\sqrt{n}}}[/tex])
= P([tex]\frac{50-49.8}{\frac{4.2}{\sqrt{39}}}[/tex] ≤ z ≤ [tex]\frac{51-49.8}{\frac{4.2}{\sqrt{39}}}[/tex])
= P(0.30 ≤ z ≤ 1.78)
= P(z ≤ 1.78) - P(z ≤ 0.3)
using z table and we get,
= 0.9625 - 0.6179
= 0.3446
= 0.345
Thus, the probability is 0.345 for the sample mean is within 50 and 51.

Jordan is working two summer jobs, making $13 per hour lifeguarding and $10 per hour walking dogs. Last week Jordan earned a total of $177 and worked 3 more hours lifeguarding than hours walking dogs. Determine the number of hours Jordan worked lifeguarding last week and the number of hours he worked walking dogs last week.
Answer:
Jordan worked 18 hours lifeguarding and 15 hours walking dogs.
Step-by-step explanation:
To solve this problem, we can set up a system of two equations to represent the given information. Let "L" represent the number of hours Jordan worked lifeguarding and "W" represent the number of hours he worked walking dogs.
The first equation will represent the total amount of money Jordan earned:
13L + 10W = 177
The second equation will represent the difference in hours between the two jobs:
L - W = 3
We can solve this system of equations using either substitution or elimination.
Using substitution, we can solve for one variable in terms of the other and substitute that expression into the other equation to solve for the other variable.
Solving the second equation for L, we get:
L = W + 3
Substituting this expression for L into the first equation, we get:
(W + 3) + 10W = 177
Combining like terms, we get:
11W + 3 = 177
Subtracting 3 from both sides, we get:
11W = 174
Dividing both sides by 11, we get:
W = 15.818181818181818
Since the number of hours worked must be a whole number, we can round down to 15 hours. Substituting this value back into the equation L = W + 3, we get:
L = 15 + 3 = 18
Therefore, Jordan worked 18 hours lifeguarding and 15 hours walking dogs.

Casual sneaker sales represent 4.5% and athletic shoe sales represent 3.2%
of total store sales. If the total store sales are $900,000, what are the dollar
sales for each department?
Answer: Casual sneaker sales = $40,500 & Athletic shoe sales = $28,800
Step-by-step explanation:
If the total store sales are $900,000 and you already have the percentages of the casual sneaker sales and athletic shoe sales, then you move the decimal point in each percentage two digits to the left, or simply multiply the percentage by .01, then take that number and multiply it by the total, $900,000
Ex:
4.5%(0.01) = .045
3.2%(0.01) = .032
.045(900,000) = 40,500
.032(900,000) = 28,800

Law of Cosines: Calculating the angles in a triangleFrom the question, we are to solve the triangle.
To solve the triangle, we will determine the value of the unknown angles.
Using the law of cosines, we can write that
cosα = (b² + c² - a²)/2bc
From the given information,
a = 34
b = 20
c = 18
Thus,
cosα = (20² + 18² - 34²)/2(20)(18)
cosα = -432/720
cosα = -0.6
α = cos⁻¹(-0.6)
α = 126.8699°
α ≈ 127°
Calculating angle β
cosβ = (a² + c² - b²)/2ac
cosβ = (34² + 18² - 20²)/2(34)(18)
cosβ = 1080/1224
β = cos⁻¹(1080/1224)
β = 28.0724°
β ≈ 28°
To determine angle γ
α + β + γ = 180° (Sum of angles in a triangle)
127° + 28° + γ = 180°
155 ° + γ = 180°
γ = 180° - 155°

if u and v are connected open subsets of r , then there is a straight line that divides each of u and v in half by area
A space whose constituents are all single point sets is said to be completely isolated. Related to this property, the space X is such that the two distinct open sets of x and y are disjoint. In some cases, they are said to be completely isolated. We use U and x and V and y, X is the becomes a join. Of course, all perfectly isolated spaces are completely isolated, but not vice versa. For example, take two copies of the rational number Q and identify them at all points except zero. The resulting quotient topology space is completely separated and subset. In fact, it is not Hausdorff, and strictly speaking, the condition of complete separation is stronger than the condition of being Hausdorff.
In topology and related mathematics, a connected space is a topological space that cannot be represented as the union of two or more disjoint, non-empty, open subsets. Connectivity is one of the most important topological properties used to distinguish topological spaces.
A subset of a topological space X is a connected space when viewed as a subspace of X.
Some related but stronger conditions are path connections, single connections, and n connections. Another related term is locally attached. It does not imply or derive connectivity.
At a given point x in the topological space X, X is an arbitrary collection of connected subsets each containing x is the union of The connected component of a point x in X is the uniquely largest connected subset of X containing is the union (the subset of X associated with containing x . The maximally connected subset of the non-empty topological space (containing) are called connected components of the space. The components of any topological space X form a partition of X. , is not empty, and their union is the entire space: each component is a closed subset of the original space. If that number is finite, each component is also an open subset. However, that may not be the case if the number of them is infinite. For example, the connected component of the set of rational numbers is an open singleton.
Let Гₓ be the topological space X and Г'ₓ be the intersection of all Clepen sets containing x (called subcomponents of x).
