Express the difference in medians as a multiple of the irq for each data set
Answers
Difference in the medians as a multiple of the IQR = 5.
Define IQR?The Interquartile Range (IQR) formula computes the median of a set of data. One of the smallest statistical measurements of dispersion is the interquartile range. The interquartile range refers to the spread between the upper and lower quartiles.
The interquartile range is defined as Upper Quartile - Lower Quartile.
According to the question,
Data set of Mount Vernon= 55, 60, 65, 70, 75, 80, 85, 90
Data set of Lakewood= 65, 70, 75, 80, 85
Data sets are already in ascending order.
Median for Mount Vernon = 70+75/2 = 77.5
Median for lower half of set= 55+60+65+70/4 = 62.5
Median for upper half of set= 75+80+85+90/4 = 82.5
IRQ for Mount Vernon = 82.5-62.5 = 20
Now similarly in case of Lakewood,
Median= 75.
Median for lower half of set = 65+70/2 = 67.5
Median for upper half of set = 80+85/2 = 82.5
IRQ = 82.5 - 67.5 = 15.
Hence, difference in IRQ = 20-15 = 5.

Rationalize the denominator: (a)52+3510(b)33x+3y3xy
Answers
For (a): 52 + 35/10m, rationalizing the denominator gives the result (25√2 + 6√5)/10.
For (b): 33x + 3y/3xy, rationalizing the denominator gives the result √3(x+y)/xy.
To rationalize the denominator, we need to multiply both the numerator and denominator by the conjugate of the denominator. The conjugate of a binomial expression is the same expression with the sign between the terms changed. For example, the conjugate of (a+b) is (a-b) and the conjugate of (a-b) is (a+b). By multiplying by the conjugate, we eliminate any radicals in the denominator.
(a) 5/√2 + 3/√5
= (5/√2)(√2/√2) + (3/√5)(√5/√5)
= (5√2)/2 + (3√5)/5
= (25√2 + 6√5)/10
(b) (3√3x + 3√y)/(3√xy)
= (3√3x + 3√y)(3√xy)/(3√xy)(3√xy)
= (9x√3xy + 9y√3xy)/(9xy)
= (9√3xy(x+y))/(9xy)
= √3(x+y)/xy
Therefore, the rationalized denominators are (a) (25√2 + 6√5)/10 and (b) √3(x+y)/xy.

The results of the matrix operations are:
-2A = [-4 0 2; -8 6 -4]B - 2A = [11 -5 -1; 9 -10 1]AC = undefinedCD = [1 13; -7 -6]To compute each matrix sum or product, we first need to determine if the operation is defined. Then, we can use the rules of matrix arithmetic to find the result.
-2A is defined, since we can multiply a matrix by a scalar. To find the result, we simply multiply each element of A by -2:
-2A = [-2(2) -2(0) -2(-1); -2(4) -2(-3) -2(2)] = [-4 0 2; -8 6 -4]
B - 2A is defined, since both matrices have the same dimensions. To find the result, we first compute -2A as shown above, then subtract each corresponding element of B and -2A:
B - 2A = [7 -5 1; 1 -4 -3] - [-4 0 2; -8 6 -4] = [7-(-4) -5-0 1-2; 1-(-8) -4-6 -3-(-4)] = [11 -5 -1; 9 -10 1]
AC is undefined, since the number of columns in A (3) does not match the number of rows in C (2).
CD is defined, since the number of columns in C (2) matches the number of rows in D (2). To find the result, we multiply each row of C by each column of D and sum the products:
CD = [(1)(3)+(2)(-1) (1)(5)+(2)(4); (-2)(3)+(1)(-1) (-2)(5)+(1)(4)] = [1 13; -7 -6]

Gail has $5,500 that she wants to put in a new savings account. She is considering two banks that are very similar. One difference she notices are the interest rates: • Neighborhood Bank - 1.2% interest, compounded annually • Beautiful Day Bank - 1.2% interest, compounded daily Based on interest, which bank would you suggest Gail pick if she plans to have her money in the account for 15 years?
Answers
Gail should pick a Beautiful bank if she plans to have her money in the account for 15 years.
How to determine which will be best bank?To determine which bank would be better for Gail, we need to calculate the future value of her investment after 15 years for each bank and compare the results.
For Neighborhood Bank, we can use the formula:
FV = P(1 + r/n)^(n*t)
where FV is the future value,
P is the principal (the initial amount invested),
r is the annual interest rate (as a decimal),
n is the number of times the interest is compounded per year,
and t is the number of years.
Plugging in the values, we get:
FV = 5,500(1 + 0.012/1)^(1*15)
FV = 5,500(1.012)^15
FV = 7,130.34
For Beautiful Day Bank, we can use the formula:
FV = P(1 + r/n)^(n*t)
Plugging in the values, we get:
FV = 5,500(1 + 0.012/365)^(365*15)
FV = 5,500(1.000032876)^5475
FV = 7,145.25
Therefore, Beautiful Day Bank would be the better choice for Gail, as she would earn a higher amount of interest and end up with a higher future value for her investment after 15 years.

Surface Area is
ππ square inches.
Answers
The total surface area of the tires making contact with the ground at any one time for the truck with 18 wheels, tire radius of 21 in, tire width of 12 in, and 20% contact area is approximately 5700.24 square inches.
The surface area of one tire making contact with the ground can be calculated as follows:
The diameter of the tire is 2 * radius = 2 * 21 in = 42 in
The length of the portion of the tire making contact with the ground is 20% of the circumference of the tire = 0.2 * π * 42 in ≈ 26.39 in
The width of the tire making contact with the ground is given as 12 in
Therefore, the surface area of one tire making contact with the ground is approximately 26.39 in * 12 in = 316.68 square inches
Since the truck has 18 wheels, the total surface area of all the tires making contact with the ground at any one time is 18 * 316.68 square inches = 5700.24 square inches.

Answers
A) To change the rectangular coordinates (-5√3, 5) to polar coordinates, we need to find the radius r and the angle θ.
The radius r can be found using the Pythagorean theorem:
r = √(x^2 + y^2)
r = √((-5√3)^2 + (5)^2)
r = √(75 + 25)
r = √100
r = 10
The angle θ can be found using the inverse tangent function:
θ = tan^(-1)(y/x)
θ = tan^(-1)(5/(-5√3))
θ = tan^(-1)(-√3/3)
θ = -π/6
So, the polar coordinates are (10, -π/6).
B) Given a = (-5, 2) and b = <4, -7>, we need to find 3a - 4b.

Lee is paid $8. 00 per hour plus a commission of 4% on all sales. Assuming Lee works 39 hours and has sales of $4,000, her gross pay is
Answers
Lee's gross pay is $472.
First, we need to calculate the commission Lee earned. To do this, we take her total sales and multiply it by her commission rate.
Commission = Total Sales x Commission Rate
Commission = $4,000 x 0.04
Commission = $160
So, Lee earned $160 in commission.
Next, we need to calculate her base pay. To do this, we multiply her hourly rate by the number of hours she worked.
Base Pay = Hourly Rate x Hours Worked
Base Pay = $8.00 x 39
Base Pay = $312
Now that we have calculated her commission and base pay, we can add them together to find her gross pay.
Gross Pay = Base Pay + Commission
Gross Pay = $312 + $160
Gross Pay = $472
This means that before any deductions (such as taxes), Lee would earn $472 for working 39 hours and making $4,000 in sales.

The functions that are odd or even can be determined by replacing x with -x and seeing if the function remains the same or changes sign.
(a) f(x) = -tan(x) is an odd function because f(-x) = -tan(-x) = tan(x) = -f(x)
(b) f(x) = tan(x+T/2) is an odd function because f(-x) = tan(-x+T/2) = -tan(x+T/2) = -f(x)
(c) f(x) = tan(x)+cot(x) is neither an odd nor an even function because f(-x) = tan(-x)+cot(-x) = -tan(x)-cot(x) ≠ f(x) or -f(x)
(d) f(x) = 5cot(x) is an even function because f(-x) = 5cot(-x) = 5cot(x) = f(x)
(e) f(x) = (tan(x))2 is an even function because f(-x) = (tan(-x))2 = (tan(x))2 = f(x)

Yes, after the residents have returned all the nameplates. 500 people, who guessed the number of blue plates
All correct will be rewarded. ask when the end How many blue tiles will there be at the end of the event? At the beginning, all plates were red.
Answers
There will be 22 blue signs at the end of the event.
Describe Probability?The probability of an event can be determined by dividing the number of favorable outcomes by the total number of possible outcomes. For example, the probability of rolling a six on a standard six-sided die is 1/6, as there is only one favorable outcome (rolling a six) out of six possible outcomes (rolling a one, two, three, four, five, or six).
To solve this problem, we need to consider the factors that determine whether a house's sign will be flipped or not. A sign will only be flipped if the number of residents can divide the house number. For example, the sign on house number 12 will be flipped by the residents of that house because 12 is divisible by 2, 3, 4, and 6 (the factors of 12).
At the beginning, all signs are red, which means that none of the houses have had their sign flipped yet. Let's start with house number 1 and consider which houses will flip its sign.
For house number 1, its sign will not be flipped because 1 is only divisible by 1.
For house number 2, its sign will be flipped because 2 is divisible by 2.
For house number 3, its sign will not be flipped because 3 is only divisible by 1 and 3.
For house number 4, its sign will be flipped because 4 is divisible by 2 and 4.
For house number 5, its sign will not be flipped because 5 is only divisible by 1 and 5.
And so on, continuing this process for all 500 houses.
We can see that the signs on the houses with numbers that have an odd number of factors will end up blue, and the signs on the houses with numbers that have an even number of factors will end up red. This is because a factor always comes in pairs, except when the number is a perfect square, in which case the factor pair is identical (e.g. 4 has factors 1, 2, and 4, which is an odd number of factors).
So we need to count the number of integers from 1 to 500 that have an odd number of factors. These are the perfect squares, which are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400, 441, and 484.

49 inches
28 inches
12.25 inches
7 inches
Answers
The height of the helium tank is 49 inches.
What is Volume?Volume refers to the amount of space occupied by a three-dimensional object, measured in cubic units.
The volume V of a cylinder is given by the formula:
V = πr²h
where r is the radius of the base and h is the height of the cylinder.
Since the diameter of the helium tank is given as 14 inches, the radius r is half of the diameter, which is 7 inches.
We also know that the volume inside the tank is 2,401π cubic inches. Therefore, we can write:
2,401π = π(7)²h
Simplifying the right-hand side, we get:
2,401π = 49πh
Dividing both sides by 49π, we get:
h = 2,401π / 49π
Simplifying, we get:
h = 49
Therefore, the height of the helium tank is 49 inches.

The following LP problem in a spreadsheet MAX: 4x1 + 4x2 Subject to: 2x1 + 4x2 <= 20, 3x1 + 5x2 <= 15, and x1, x2 >= 0.A spreadsheet is a type of software that allows users to store and analyze data in a grid-like format of rows and columns. Spreadsheets are commonly used for data entry, financial modeling, and other calculations.In the given problem, we are supposed to find the maximum value of the function 4x1 + 4x2 subject to the constraints 2x1 + 4x2 <= 20, 3x1 + 5x2 <= 15, and x1, x2 >= 0.The first two constraints are represented by inequalities. That means, the values of x1 and x2 can be any non-negative values that satisfy the constraints. Mathematically, the constraints can be represented as:2x1 + 4x2 <= 20⇒ x2 <= 5 - 0.5x1--------(1)3x1 + 5x2 <= 15⇒ x2 <= 3 - 0.6x1--------(2)Note that, we have represented the constraints in such a way that x2 is the subject of the inequality. This is done to make it easier to graph and find the feasible region.To find the feasible region, we need to graph both inequalities (1) and (2) on a coordinate plane. The feasible region is the shaded area that is common to both regions. It is given below:The feasible region is the triangular-shaped region. Since x1 and x2 are both non-negative, we need to consider only the values of x1 and x2 that are within the feasible region.Now, to maximize the function 4x1 + 4x2, we need to find the optimal solution. We do this by finding the intersection points of the lines that represent the equation 4x1 + 4x2 = k, where k is a constant.The equation 4x1 + 4x2 = k can be rearranged as x2 = (-x1 + k/4)This equation represents a line with a slope of -1 and a y-intercept of k/4. We can graph this line for different values of k to find the optimal solution. The line for k = 0 is shown below:We can see that the line passes through the feasible region at point (0, 0) and (5, 0). This means that the maximum value of the function is 4x1 + 4x2 = 4(5) + 4(0) = 20 at point (5, 0).Thus, the maximum value of the function 4x1 + 4x2 subject to the constraints 2x1 + 4x2 <= 20, 3x1 + 5x2 <= 15, and x1, x2 >= 0 is 20 at x1 = 5 and x2 = 0.

sin A sin B sin C
------ = ------- = -------
a b c
True, the law of sines can be used when you are given 3 sides of a triangle, and you are solving for an angle.
The law of sines 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 a given triangle. Therefore, if you know the lengths of all three sides of a triangle, you can use the law of sines to solve for one of the angles.
What are angles?An angle is the measure that determines two straight lines, which when joined together create a point of origin, which is called the vertex of the angle.
The unit of measurement associated with angles is degrees.

Answer:
33361
Step-by-step explanation:
The equation appears to be
75 ( 1 + 0.84 )^x
Since it increases by 84% every 2 days, you'd devide 20 by 2, making 10
So to do the equation you'd shove that into a calculator since no one wants to hand do that sort of equation.
75 ( 1 + 0.84 )^10 = 33361.0332844 = 33361
Use the Law of Sines to solve the triangle. Round your answers to two decimal places. A-22, C - 51.4%, c-2.69 B=____ a=______ b=_______
Answers
Answer:
a/sin(A) = b/sin(B) = c/sin(C)
where a, b, and c are the side lengths of the triangle, and A, B, and C are the opposite angles, respectively.
We are given A, C, and c, so we can use the Law of Sines to find B, a, and b.
a/sin(A) = c/sin(C)
a/sin(22) = 2.69/sin(51.4)
a = sin(22) * (2.69/sin(51.4))
a = 1.00
b/sin(B) = c/sin(C)
b/sin(B) = 2.69/sin(51.4)
b = sin(B) * (2.69/sin(51.4))
We can use the fact that the sum of the angles in a triangle is 180 degrees to find B:
B = 180 - A - C
B = 180 - 22 - 51.4
B = 106.6
Now we can substitute the values we have found into the Law of Sines to find b:
a/sin(A) = b/sin(B)
1/sin(22) = b/sin(106.6)
b = sin(106.6) * (1/sin(22))
b = 2.69
Therefore, B is approximately 106.6 degrees, a is approximately 1.00, and b is approximately 2.69.

Consider the following vectors v1 = 1 , v2 = 2 , and v3 = -1 . For what values (s) -1 1 3
2 1 h
of h is the set. {v1, v2, v3] linearly dependent? Work must be shown for this question. h = -4
h = 4
all real number h ≠ 4 all real number h ≠ -4
Answers
The set of vectors {v1, v2, v3} is linearly dependent for all real number h ≠ 4 and all real number h ≠ -4.
The set of vectors {v1, v2, v3} is linearly dependent if there exists a set of real numbers a, b, and c such that a*v1 + b*v2 + c*v3 = 0 and at least one of a, b, or c is not equal to zero. In this case, we can write the equation as:
a*1 + b*2 + c*(-1) = 0
We can rearrange this equation to solve for h:
h = -a - 2*b + c
Now we can plug in the values for v1, v2, and v3:
h = -1 - 2*2 + (-1)*(-1)
h = -4
Therefore, the set of vectors {v1, v2, v3} is linearly dependent when h = -4.
Alternatively, we can also use the determinant of the matrix formed by the vectors to determine when the set is linearly dependent. The determinant of the matrix is given by:
| 1 2 -1 |
| -1 1 3 | = (1)(1)(h) + (2)(3)(-1) + (-1)(-1)(2) - (-1)(1)(-1) - (2)(-1)(1) - (1)(3)(2)
| 2 1 h |
Simplifying this equation gives:
h - 6 - 2 + 1 + 2 - 6 = 0
h - 11 = 0
h = 11
Therefore, the set of vectors {v1, v2, v3} is also linearly dependent when h = 11.
So the set of vectors {v1, v2, v3} is linearly dependent for all real number h ≠ 4 and all real number h ≠ -4.

At the same time a 612 -ft teacher casts a 9-ft shadow, a nearby flagpole casts a 3112 -ft shadow. How tall is the flagpole?
Answers
The height of the flagpole is approximately 23,047.11 feet.
To resolve this issue, we can make use of the similar triangles property. The teacher, the flagpole, and each of their corresponding triangles are similar because they have the same angles.
Let h be the height of the flagpole. Then, we can set up the following proportion:
h / 3112 = 612 / 9
When we simplify this ratio, we obtain:
h = (3112 x 612) / 9
h = 207424 / 9
h ≈ 23,047.11 feet
Hence, the flagpole is roughly 23,047.11 feet tall.
