Hello, I am Alyssa Ann Verrett.
Put the numbers in order:
City A: {2, 3.5, 4, 4, 5, 5.5}
City B: {3.5, 4, 5, 5.5, 6, 6}
a)
The mean monthly rainfall amount for city A: 4 in;
The mean monthly rainfall amount for city B: 5 in;
b)
The MAD monthly rainfall amount for city A: 0.8 in;
The MAD monthly rainfall amount for city B: 0.8 in;
c)
The median monthly rainfall amount for city A: 4 in;
The median monthly rainfall amount for city A: 5.25 in;
Step-by-step explanation:
a) The general definition of mean of a set X is:
mean = (x₁ + x₂ + x₃ + ... xₙ)/n
For City a:
mean = (4+3.5+5+5.5+4+2)/6 = 4
For City b:
mean = (5+6+3.5+5.5+4+6)/6 = 5
b) The general definition of mean absolute deviation of a set X is:
MAD = (|x₁-mean| + |x₂-mean| + |x₃-mean| + ... + |xₙ-mean|)/n
For City a:
MAD = ( |4-4| + |3.5-4| + |5-4| + |5.5-4| + |4-4| + |2-4| )/6 = (0 + 0.5 + 1 + 1.5 + 0 + 2)/6 = 5/6 =0.8
For City b:
MAD = ( |5-5| + |6-5| + |3.5-5| + |5.5-5| + |4-5| + |6-5| )/6 = (0 + 1 + 1.5 + 0.5 + 1 + 1)/6 = 5/6 = 0.8
c) The general definition of median depends on the quantity of elements in the set X and it represents the middlemost value of the set:
When the quantity is odd:
median= x₍ₙ₊₁₎/₂
When the quantity is even:
median= (xₙ/₂ + x ₙ₊₂/₂) /2
For City A:
median = 2, 3.5, 4, 4, 5, 5.5 = (4 + 4) / 2 = 4
For City B:
median = 3.5, 4, 5, 5.5, 6, 6 = (5 + 5.5) / 2 = 5.25

which rule best represents the dilation applied to rectangle qrst to create rectangle q'r's't'?
o a. (x, y) - (3x, 3y)
o b. (x,y) - (1/3x, 1/3y)
o c. (x, y) - (x+3, y + 3)
o d. (x, y) - (x + 1/3, y + 1/3)
The correct answer is option (d) (x, y) → (x + 1/3, y + 1/3).
What is the rule that best represents the dilation applied to rectangle qrst to create rectangle q'r's't'?The dilation is a type of transformation that changes the size of the object, but not the shape. It can be represented by a rule in which each point of the original object is multiplied or divided by a constant factor. In this case, since the center of dilation is the origin, we can find the constant factor by dividing the coordinates of the corresponding points of the two rectangles.
Let's take the point Q(x, y) in rectangle QRST and its corresponding point Q'(x', y') in rectangle Q'R'S'T'. Since the dilation is centered at the origin, we have:
x' = k * x
y' = k * y
where k is the constant factor of dilation. We can find k by dividing the corresponding sides of the rectangles. For example, the length of QR is 4 units, and the length of Q'R' is 4/3 units. Therefore, k = 4/3.
Using this value of k, we can find the coordinates of any point in rectangle QRST that corresponds to a point in rectangle Q'R'S'T'. For example, point R(6, 2) in rectangle QRST corresponds to point R'(6 + 1/3, 2 + 1/3) = (20/3, 7/3) in rectangle Q'R'S'T'.
Hence, the correct answer is (x, y) → (x + 1/3, y + 1/3).

Yvette cuts a hole from a rectangular panel to make a window. She wants to determine how
much of the panel is left after she cuts the hole. She writes:
(fraction left)
(area of panel) - (area of hole)
(area of panel)
If the panel is 3 feet by 2 feet, and the hole is 1 foot by foot, what is the fraction left?
The area of the panel left after she cuts the hole is 5.215 ft²
Given that a circular hole of 1 foot by foot has been cut out of a rectangular panel of 3 feet by 2 feet,
We need to find the area of the remaining part after the cutting of the hole,
So, we will find the same by subtracting the area of the hole from the area of the panel.
So, area of the hole = π×radius² = 3.14×0.5² = 0.785 ft²
Area of the panel = length × width = 3 × 2 = 6 ft²
Area remaining part = 6-0.785 = 5.215 ft²
Hence the area of the panel left after she cuts the hole is 5.215 ft²

Sand falls from an overhead bin and accumulates in a conical pile with a radius that is alwavs two times its heiaht. Suppose the height of the pile increases at a rate of 2 cm/s when the pile is 11 cm high. At what rate is the sand leaving the bin at that instant?
To solve this problem, we need to use related rates. Let's start by drawing a diagram:
```
/\
/ \
/ \
/ \
/ \
/__________\
```
We know that the radius of the conical pile is always two times its height, so we can label the diagram as follows:
```
/\
/ \
/ \
/ \
/ \
/__________\
/| r=2h \
/ |___________\
```
Now we need to find an equation that relates the height of the pile to its radius. We can use the formula for the volume of a cone:
```
V = (1/3)πr^2h
```
We want to solve for h in terms of r:
```
V = (1/3)πr^2h
3V/πr^2 = h
```
Now we can differentiate both sides of this equation with respect to time:
```
d/dt (3V/πr^2) = d/dt h
0 = (3/πr^2) dV/dt - (2/πr^3) dr/dt
```
We're given that the height is increasing at a rate of 2 cm/s when the pile is 11 cm high, so we know that:
```
dh/dt = 2 cm/s
h = 11 cm
```
We want to find the rate at which sand is leaving the bin, which is given by `dV/dt`. We can solve for this using the equation we derived:
```
0 = (3/πr^2) dV/dt - (2/πr^3) dr/dt
dV/dt = (2/3)πr^2 (dh/dt) / r
```
Now we just need to plug in the values we know:
```
dh/dt = 2 cm/s
h = 11 cm
r = 2h = 22 cm
dV/dt = (2/3)π(22)^2 (2) / 22
dV/dt = 264π/3
```
So the rate at which sand is leaving the bin when the pile is 11 cm high is `264π/3 cm^3/s`.
To solve this problem, we can use the relationship between the radius and height of the conical pile, as well as the given rate of height increase.
Since the radius (r) is always two times the height (h), we have r = 2h. The volume (V) of a cone is given by the formula V = (1/3)πr^2h. We can substitute r with 2h, so V = (1/3)π(2h)^2h.
Now, let's differentiate both sides with respect to time (t):
dV/dt = (1/3)π(8h^2)dh/dt
When the height is 11 cm, the rate of height increase (dh/dt) is 2 cm/s. We can substitute these values into the equation:
dV/dt = (1/3)π(8(11)^2)(2)
Solving for dV/dt:
dV/dt ≈ 2046.92 cm³/s
At that instant, the sand is leaving the bin at a rate of approximately 2046.92 cm³/s.

A velociraptor runs 5m [e] , 10 m [w], 3m [s], & 2m [w] in 10 seconds. calculate speed & velocity.
The velociraptor's speed is 2 m/s, and its velocity is -0.3 m/s [w].
What is the total distance covered?
To calculate the speed and velocity of the velociraptor, we need to first find the total distance it covered and the displacement.
Total distance = 5m + 10m + 3m + 2m = 20m
Displacement = Final position - Initial position
Displacement = (2m [w]) - (5m [e])
Displacement = -3m [w]
Velocity is defined as displacement per unit time, while speed is defined as distance per unit time.
Velocity = Displacement / Time
Velocity = -3m [w] / 10s
Velocity = -0.3 m/s [w]
Speed = Total distance / Time
Speed = 20m / 10s
Speed = 2 m/s
Therefore, the velociraptor's speed is 2 m/s, and its velocity is -0.3 m/s [w].

In triangle abc, point d is on side ac, ab=bd=dc=12 inches, and measurement of angle bdc= 2 times the measurement of angle abd. find ac
The length of AC in triangle ABC is 24 inches.
In triangle ABC, let point D be on side AC such that AB = BD = DC = 12 inches. We are given that the measure of angle BDC is twice the measure of angle ABD.
To find the length of AC, we can use the Law of Cosines. This law relates the lengths of the sides of a triangle to the cosine of one of its angles. In this case, we can apply the Law of Cosines to triangle ABD to find the length of AD:
AD^2 = AB^2 + BD^2 - 2 * AB * BD * cos(ABD)
Since AB = BD = 12 inches, we have:
AD^2 = 12^2 + 12^2 - 2 * 12 * 12 * cos(ABD)
AD^2 = 288 - 288 * cos(ABD)
Now, let's consider triangle BDC. We are given that the measure of angle BDC is twice the measure of angle ABD. Let's denote the measure of angle ABD as x. Therefore, the measure of angle BDC is 2x.
Since the sum of angles in a triangle is 180 degrees, we can write:
x + 2x + angle BCD = 180
3x + angle BCD = 180
angle BCD = 180 - 3x
Now, let's apply the Law of Cosines to triangle BDC to find the length of BC:
BC^2 = BD^2 + CD^2 - 2 * BD * CD * cos(BDC)
BC^2 = 12^2 + 12^2 - 2 * 12 * 12 * cos(2x)
BC^2 = 288 - 288 * cos(2x)
Since AD = DC, we have AD = 12 inches. Now we can write the equation for the total length AC:
AC = AD + DC
AC = 12 + 12
AC = 24 inches
Therefore, the length of AC in triangle ABC is 24 inches.

Hugo rides the bus to work every day, a distance of 18 miles. The distance on the route map between the station by Hugos house and the station by his work is 3 inches. What is the maps scale? 1 inch = _____ miles.
The maps scale is 1 inch = 6 miles. This means that for every inch on the map, it represents 6 miles in real-life distance.
To determine the scale, we need to know the relationship between the distance on the map and the actual distance. In this case, the distance on the route map between Hugo's house and his work is 3 inches, and the actual distance he travels by bus is 18 miles.
To find the scale, we can set up a proportion using the given information:
(distance on the map in inches) / (actual distance in miles) = (1 inch) / (x miles)
Now, we can plug in the known values:
(3 inches) / (18 miles) = (1 inch) / (x miles)
To solve for x, we can cross-multiply:
3 inches * x miles = 18 miles * 1 inch
3x = 18
Now, divide both sides by 3:
x = 6
So, the scale of the map is 1 inch = 6 miles.

Which properties ensure that there exists ?
a 'c' in (-1, 1) at which f'(c) = 0, given f(-1) = f(1) = and the properties A, B, and C.
First, let's define the properties:
f(1) = 2
f is continuous on (-1, 1]
f(x) = (22/3) - x^2
To ensure that there exists a 'c' in (-1, 1) at which f'(c) = 0, we will use the Mean Value Theorem (MVT). MVT states that if a function is continuous on a closed interval and differentiable on an open interval, then there exists at least one 'c' in the interval where the derivative is 0.
Looking at property B, it states that f is continuous on (-1, 1], which satisfies the first condition of the MVT. Property C provides a specific function for f(x), which is differentiable on (-1, 1) since it is a polynomial function. Therefore, properties B and C together ensure that there exists a 'c' in (-1, 1) at which f'(c) = 0.

Piotr has run the first 24 miles of a race which means he is 85% finished. How long is the race?
The total length of the race is approximately 28.24 miles.
To determine the total length of the race, we can use the given information: Piotr has completed 24 miles, which represents 85% of the race. We can set up a proportion to find the total length. Let 'x' represent the full length of the race:
(24 miles) / x = 85% / 100%
To solve for 'x', we can first convert the percentage to a decimal by dividing 85 by 100, resulting in 0.85:
24 / x = 0.85
Next, we can cross-multiply:
0.85 * x = 24
Now, we can solve for 'x' by dividing both sides by 0.85:
x = 24 / 0.85
x ≈ 28.24 miles
Therefore, the total length of the race is approximately 28.24 miles. Piotr has completed 85% of this distance, which means he has run 24 miles and has around 4.24 miles remaining to finish the race.

where M is the total mass of the plate, R is the region of integration (0 ≤ x ≤ 1, 0 ≤ y ≤ 1), and dA is the differential area element.
We can calculate the total mass M of the plate as follows:
M = ∬(R) ρ(x,y) dA = α/2 + β/2 = (α + β)/2
Using the given density function, we can calculate the integrals for X and Y:
X = (1/M) ∬(R) x ρ(x,y) dA = (2/αβ) ∬(R) x(αx+βy) dA = (2/3)(α+β)
Y = (1/M) ∬(R) y ρ(x,y) dA = (2/αβ) ∬(R) y(αx+βy) dA = (2/3)(α+β)
Thus, the coordinates of the centroid are (X, Y) = ((2/3)(α+β), (2/3)(α+β)).
Now, if we substitute X + Y = (4/3)(α+β) into the equation x + y = 7/6, we get:
x + y = 7/6
2x + 2y = 7/3
2(x+y) = 4/3(α+β)
x+y = (2/3)(α+β)
which shows that the centroid lies on the line x + y = 7/6. Therefore, the center of mass must also lie on this line.

Determine whether the geometric series is convergent or divergent. If it is convergent, find the sum. (If the quantity diverges, enter DIVERGES.) 00 7 80 3| n n = 1
|r| = 7/80 < 1, the series is convergent. The sum = 0/(1-7/80) = 0. the sum of the geometric series is 0.
The geometric series with first term 0 and common ratio 7/80 is given by 0, 7/80, (7/80)², (7/80)³, ... In general, the nth term is (7/80)ⁿ⁻¹.
To determine whether this series is convergent or divergent, we can use the formula for the sum of an infinite geometric series:
sum = a/(1-r)
where a is the first term and r is the common ratio. In this case, a = 0 and r = 7/80.
If |r| < 1, then the series converges to the sum given by the above formula. If |r| ≥ 1, then the series diverges.
In this case, |r| = 7/80 < 1, so the series is convergent. The sum is given by:
sum = 0/(1-7/80) = 0
Therefore, the sum of the geometric series is 0.

h(t) = -16t^2 +90t
how many seconds will it take for the ball to reach its maximum height
The amount of time it would take for the ball to reach its maximum height is 2.1825 seconds.
How to determine the time when the ball would reach its maximum height?Based on the information provided, we can logically deduce that the height (h) in feet, of this ball above the ground is related to time by the following quadratic function:
Next, we would determine the maximum height of this ball by taking the first derivate in order to determine the time (t) it takes as follows;
h(t) = -16t² + 90t
h'(t) = -32t + 90
90 = 32t
t = 90/32 = 2.1825 seconds.
h(2.1825) = -16(2.1825)² + 90(2.1825)
h(2.1825) = 120.21 feet.

Using area formula for rectangles, we can find the new area of the rectangle to be 7350m².
The new dimensions are:
Length = 105m
Breadth = 70m
Define a rectangle?A rectangle is a quadrilateral with parallel opposite sides and equal angles. There are a lot of rectangular objects all around us. Each rectangle's two defining characteristics are its length and breadth. A rectangle's longer and shorter sides are its width and length, respectively.
Here in the question,
Dimensions of the rectangle are as follows:
Length, l = 42m.
Width, w = 28m.
Scale factor here is 1: 5/2
Now,
Let the new width be x.
The new width will be:
28/x = 1/ (5/2)
Cross multiplying:
⇒ 28 × 5/2 = x
⇒ x = 70m.
So, new width = 70m.
Now, let new length be x.
So,
42/x = 1/ (5/2)
Cross multiplying:
⇒ x = 42 × 5/2
⇒ x = 105m.
So, the new length = 105m.
Now new area will be:
70 × 105
= 7350m².

What is triangle?A triangle is a geometrical shape that consists of three straight sides and three angles. It is a polygon with three vertices, and the sum of its interior angles always adds up to 180 degrees. Triangles are classified based on the length of their sides and the measure of their angles. The most common types of triangles are equilateral, isosceles, and scalene, based on the length of their sides, and acute, right, and obtuse, based on the measure of their angles. Triangles have a wide range of applications in mathematics, physics, engineering, and other fields.
Here,
Therefore, in this triangle, sin(67°) = 67/x, where x is the length of the hypotenuse.
We can rearrange this equation to solve for x:
x = 67 / sin(67°)
Using a calculator, we find that sin(67°) is approximately 0.921, so:
x = 67 / 0.921
x ≈ 72.73

There is a 2-column table with 6 rows representing the value of a savings account at the end of each year for 6 years. The relationship between the years and the value of the account is exponential, and there is a rate of change in this exponential relationship.
To find the rate of change in this exponential relationship, you can follow these steps:
1. Divide the value of the account in the second year by the value of the account in the first year: 5,512.50 / 5,250 = 1.05.
2. Since the relationship is exponential and the rate of change is constant, the account's value will increase by the same factor every year. In this case, the rate of change is 1.05, which means that after each year, the value of the account is 1.05 times as large as the previous year.
In summary, the rate of change in the exponential relationship between the increasing years and the increasing value of the account is 1.05, meaning that after each year, the value of the account is 1.05 times as large as the previous year.
