Adding another 12 to the data set would increase the sum of the values by 12, resulting in a new sum of 239. To find the new mean, we divide the new sum by the total number of values in the set, which is now 8. So the new mean would be 29.875, which is slightly lower than the original mean of 31.6.
To find the new median, we first need to rearrange the values in ascending order: 12, 18, 26, 32, 41, 46, 46, 12. Since there are now an even number of values, we take the average of the middle two, which in this case is (26 + 32) / 2 = 29. So the new median would be 29, which is lower than the original median of 32.
In summary, adding another 12 to the data set would slightly decrease the mean and lower the median.

A function is a rule that assingns each value of independent variable to exactly value of the dependent variable
A function is a rule that assingns each value of independent variable to exactly one value of the dependent variable.
A function is a mathematical concept that relates two sets of values, known as the domain and the range. The domain is the set of independent variables, while the range is the set of dependent variables. A function is a rule that assigns to each value in the domain exactly one value in the range.
For example, if we have a function f(x) = 2x + 3, the domain would be any possible value of x, and the range would be any possible value of 2x + 3. So if we put x = 2, then f(x) = 2(2) + 3 = 7. Therefore, the function assigns the value of 7 to the value of 2 in the domain.
Functions are used in various branches of mathematics, science, and engineering to model and analyze relationships between two or more variables. They are an important concept in calculus, where they are used to study rates of change and optimization problems.

a police car is parked 40 feet due north of a stop sign on straight road. a red car is travelling towards the stop sign from a point 160 feet due east on the road. the police radar reads that the distance between the police car and the red car is decreasing at a rate of 100 feet per second. how fast is the red car actually traveling along the road?
The red car is actually traveling along the road at a speed of approximately 26.67 feet per second.
We can start by drawing a diagram of the situation:
P (police car)
|
|
|
40 | S (stop sign)
-------|--------------------
| 160
| R (red car)
Let's use the Pythagorean theorem to find the distance between the police car and the red car at any time t:
d(t)² = 40² + (160 - v*t)²
Where v is the speed of the red car in feet per second, and d(t) is the distance between the police car and the red car at time t.
We want to find how fast the red car is actually traveling along the road, so we need to find v when the distance between the police car and the red car is decreasing at a rate of 100 feet per second:
d'(t) = -100
We can take the derivative of the equation for d(t) with respect to time:
2d(t)d'(t) = 0 + 2(160 - v*t)(-v)
Simplifying and plugging in d'(t) = -100, we get:
-4000 + 2v²t = -100(160 - vt)
Solving for v, we get:
v = 80/3 ≈ 26.67 feet per second

Francium is a radioactive element discovered by Marguerite Perey in 1939 and named after her country. Francium has a half-life of 22 minutes.
a) Write an exponential function that models the mass how many grams remain from a 480-gram sample after t minutes.
b) How many grams remain after 2 hours?
After 2 hours, approximately 4.38 grams of Francium remain from the 480-gram sample.
What is Algebraic expression ?
An algebraic expression is a combination of variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. It may contain one or more terms, with each term separated by a plus or minus sign. Algebraic expressions are used in algebra to represent mathematical relationships and formulas.
a) To write an exponential function that models the mass of Francium remaining after t minutes, we can use the formula:
N = N0 * [tex](1/2)^{(t / t1/2)}[/tex]
where N is the amount remaining after time t, N0 is the initial amount, t1/2 is the half-life, and (t/t1/2) means raised to the power of t/t1/2.
In this case, the initial amount is 480 grams, the half-life is 22 minutes, and we want to find the amount remaining after t minutes. Therefore, the exponential function that models the mass of Francium remaining after t minutes is:
N = 480 * [tex](1/2)^{t/22}[/tex]
b) 2 hours is equal to 120 minutes. To find how many grams of Francium remain after 2 hours, we can substitute t = 120 into the exponential function we found in part a):
N = 480 *[tex](1/2)^{ (120 / 22) }[/tex] ≈ 4.38 grams
Therefore, after 2 hours, approximately 4.38 grams of Francium remain from the 480-gram sample.

Use Euler's method with step size 0.5 to compute the approximate y-values yi, y(0.1), y(0,2), of the solution of the initial-value problem y' = 1 – 2x – 2y, y(0) = – 3. y1 = y2 = y3 = y4 =
The approximate values of y at x = 0.1, 0.2, 0.3, and 0.4 are all equal to y1 = y2 = y3 = y4 = 0.5, as we only used the first step of Euler's method.
We can use Euler's method with a step size of 0.5 to approximate the solution of the given initial-value problem as follows:
First, we need to find the slope at the initial point (0, -3):
y' = 1 - 2x - 2y
y'(0, -3) = 1 - 2(0) - 2(-3) = 7
Using Euler's method, we can approximate the solution at x = 0.5:
y(0.5) ≈ y(0) + hy'(0, -3) = -3 + 0.57 = 0.5
Next, we can use the approximate value y(0.5) to approximate the solution at x = 1:
y(1) ≈ y(0.5) + hy'(0.5, 0.5) = 0.5 + 0.5(1 - 2(0.5) - 2(0.5)) = -0.5
Similarly, we can use the approximate value y(1) to approximate the solution at x = 1.5:
y(1.5) ≈ y(1) + hy'(1, -0.5) = -0.5 + 0.5(1 - 2(1) - 2(-0.5)) = -1.25
Finally, we can use the approximate value y(1.5) to approximate the solution at x = 2:
y(2) ≈ y(1.5) + hy'(1.5, -1.25) = -1.25 + 0.5(1 - 2(1.5) - 2(-1.25)) = -2.4375
Therefore, the approximate values of y at x = 0.1, 0.2, 0.3, and 0.4 are all equal to y1 = y2 = y3 = y4 = 0.5, as we only used the first step of Euler's method.

based on the table, which function models this situation?
The function that models this situation is f(n) = -3n + 24.
To find the function, we need to analyze the relationship between the number of meals dispensed (n) and the amount of pet food remaining (f(n)).
1. Observe the change in f(n) when n increases by 1 meal. From n=1 to n=3, f(n) decreases from 21 to 15, a change of -6. From n=6 to n=7, f(n) decreases from 6 to 3, a change of -3.
2. The decrease in f(n) is not constant, so the function is not linear. However, the decrease becomes smaller as n increases.
3. Consider the average rate of change in f(n) per meal: (-6/2) = -3, (-3/1) = -3.
4. Since the average rate of change is constant, the function is linear.
5. The function has the form f(n) = -3n + b. To find b, plug in the value of n and f(n) from the table: 21 = -3(1) + b, which gives b = 24.

3) Find the maximum and minimum values of f(x,y) = xyon the region inside the triangle whose vertices are (6,2), (0,3), and (6.0).
Therefore, the maximum value of f(x,y) inside the triangle is 80/9, which occurs along the line y = (-1/2)x + 4 at the point (8/3, 10/3), and the minimum value is -32, which occurs at the critical point (-8,4).
To find the maximum and minimum values of f(x,y) = xy on the region inside the triangle whose vertices are (6,2), (0,3), and (6,0), we use the method of Lagrange multipliers.
First, we need to find the critical points of f(x,y) subject to the constraint that (x,y) lies inside the triangle. We can express this constraint using the equations of the lines that form the sides of the triangle:
y = (-1/2)x + 4
y = (3/2)x
y = 0
Next, we set up the Lagrange multiplier equation:
∇f = λ∇g
where g(x,y) is the equation of the constraint, i.e., the triangle.
We have:
f(x,y) = xy
∇f = <y, x>
g(x,y) = y - (-1/2)x - 4 = 0
∇g = <-1/2, 1>
Setting ∇f = λ∇g, we get:
y = (-1/2)λ
x = λ
Substituting these into the constraint equation, we get:
(-1/2)λ - 4 = 0
Solving for λ, we get:
λ = -8
Substituting this into y = (-1/2)λ and x = λ, we get:
x = -8 and y = 4
Therefore, the only critical point of f(x,y) inside the triangle is (-8,4).
Next, we need to check the values of f(x,y) at the vertices and along the sides of the triangle.
At the vertices:
f(6,2) = 12
f(0,3) = 0
f(6,0) = 0
Along the line y = (3/2)x:
f(x, (3/2)x) = (3/2)x^2
Using the vertex (6,2) and the x-intercept (4/3, 2), we can see that the maximum value of (3/2)x^2 on this line occurs at x = 4. Therefore, the maximum value of f(x,y) along this line is:
f(4,6) = 24
Along the line y = (-1/2)x + 4:
f(x, (-1/2)x + 4) = (-1/2)x^2 + 4x
Using the vertex (6,2) and the x-intercept (8,0), we can see that the maximum value of (-1/2)x^2 + 4x on this line occurs at x = 8/3. Therefore, the maximum value of f(x,y) along this line is:
f(8/3,10/3) = 80/9
Finally, we need to check the values of f(x,y) at the critical point (-8,4). We have:
f(-8,4) = -32

To find the total volume of the silo, we need to add the volume of the hemisphere on top to the volume of the cylinder at the bottom.
The volume of a hemisphere is given by:
V_hemi = (2/3)πr^3
where r is the radius of the hemisphere.
Substituting r = 9ft, we get:
V_hemi = (2/3)π(9ft)^3
= 1521π ft^3
The volume of a cylinder is given by:
V_cyl = πr^2h
where r is the radius of the cylinder and h is its height.
Substituting r = 9ft and h = 35ft, we get:
V_cyl = π(9ft)^2(35ft)
= 2673π ft^3
Therefore, the total volume of the silo is:
V_silo = V_hemi + V_cyl
= 1521π + 2673π

) Nadia buys 4 1/5 pounds of plums. Nadia used a 55 cent coupon off her entire purchase. Her total after the coupon was $3. 23. If c represents the cost per pound for the plums, create and solve an equation to determine the cost per pound for the plums
If c represents the cost per pound for the plums, the cost per pound for the plums is $0.90.
First, we need to determine the total cost of the plums before the coupon was applied.
4 1/5 pounds can be written as a mixed number:
4 1/5 = 21/5
So, the total cost of the plums without the coupon can be found by multiplying the cost per pound (c) by 21/5:
Total cost = c * 21/5
Now we can create an equation to represent the total cost after the coupon was applied:
Total cost - coupon = $3.23
Substituting the expression for total cost:
c * 21/5 - 0.55 = 3.23
To solve for c, we can start by adding 0.55 to both sides:
c * 21/5 = 3.78
Then, we can isolate c by multiplying both sides by the reciprocal of 21/5:
c = 3.78 / (21/5)
c = 0.90
Therefore, the cost per pound for the plums is $0.90.

Integrate fover the given curve. f(x,y) = x+ y, C: x^2 + y^2 = 4 in the first quadrant from
(2,0) to (0,2)
The integral of f(x, y) = x + y over the given curve is 8.
To integrate the function f(x, y) = x + y over the curve C: x² + y² = 4 in the first quadrant from (2, 0) to (0, 2), we will use the line integral. Since the curve is a circle, we can parameterize it using polar coordinates as follows:
x = 2cos(θ)
y = 2sin(θ)
Now, let's find the derivatives:
dx/dθ = -2sin(θ)
dy/dθ = 2cos(θ)
Next, we substitute x and y in f(x, y):
f(x, y) = 2cos(θ) + 2sin(θ)
Now, we can set up the line integral:
∫[f(x, y) * ||dr/dθ||]dθ
Since ||dr/dθ|| = sqrt((-2sin(θ))^2 + (2cos(θ))^2) = 2, the line integral becomes:
∫[2cos(θ) + 2sin(θ)] * 2 dθ
To find the limits of integration, we can use the points (2, 0) and (0, 2). In polar coordinates, these points correspond to θ = 0 and θ = π/2.
So, the line integral becomes:
∫[4cos(θ) + 4sin(θ)]dθ from 0 to π/2
Now, we can integrate and evaluate:
[4sin(θ) - 4cos(θ)] from 0 to π/2 = [4(1) - 4(0)] - [4(0) - 4(1)] = 8
Thus, the integral of f(x, y) = x + y over the given curve is 8.

There are 30 skittles in a box, for every 5 green there are 7 yellow, how many yellows are there in the box
There are 42 yellow skittles in the box.
Based on the given information, we know that the ratio of green skittles to yellow skittles is 5:7. This means that for every 5 green skittles, there are 7 yellow skittles.
To find out how many yellow skittles are in the box, we need to know how many sets of 5 green skittles there are. We can do this by dividing the total number of skittles in the box (30) by 5 (since there are 5 green skittles for every set).
30 ÷ 5 = 6
This means there are 6 sets of 5 green skittles in the box.
Now we can use the ratio of 5:7 to find out how many yellow skittles there are in each set:
5 green skittles : 7 yellow skittles
Since there are 7 yellow skittles in each set, we can find the total number of yellow skittles by multiplying 7 by the number of sets (6):
7 x 6 = 42
There are 42 yellow skittles in the box.

A designer is planning a trai
l mix box that is
shaped l
ike a rectangular prism. The front of
the box must have the width and height shown.
The volume of the box must be 162 cubic
inches. What must be the depth, d, of the box?
HELP
The depth of trail mix box that is shaped like a rectangular prism must be 2.4 inches.
How can we estimate the depth of the box?We are going to use the formula for determining volume to work out the depth of the rectangular prism.
The volume of a rectangular prism is given by the formula:
V = l × w × h
where:
V = the volume
l = the length
w = the width
h = the height.
Given:
w = 7.5 inches
h = 9 inches
V = 162 cubic inches
Now, we are to find the value of d, the depth of the box, which corresponds to the length of the rectangular prism.
Substituting the values into the formula for volume:
162 = d × 7.5 × 9
Simplifying the right-hand side:
162 = 67.5d
Dividing both sides by 67.5, we get:
d = 162 ÷ 67.5
d = 2.4 inches
Therefore, the depth of the box shaped as rectangular prism = 2.4 inches.

Determine the unique solution, y(x), to the differential equation that satisfies the given initial condition. dy/dx = 8x⁷/y⁴, y(0) = 4
y(x) = ...
The unique solution, y(x), to the given differential equation with initial condition y(0) = 4 is
:
y(x) = [-(6x⁸ - 64)]¹/³
Determine the unique solution?
To determine the unique solution, y(x), to the given differential equation with initial condition y(0) = 4, we first need to separate the variables and integrate both sides with respect to x and y, respectively.
dy/y⁴ = 8x⁷ dx
Integrating both sides, we get:
-1/3y³ = 2x⁸ + C
where C is the constant of integration.
Now we can use the initial condition y(0) = 4 to solve for C:
-1/3(4)³ = 2(0)⁸ + C
C = -64/3
Substituting C back into the previous equation, we get:
-1/3y³ = 2x⁸ - 64/3
Multiplying both sides by -3 and taking the cube root, we get:
y(x) = [-(6x⁸ - 64)]¹/³
Therefore, the unique solution, y(x), to the given differential equation with initial condition y(0) = 4 is:
y(x) = [-(6x⁸ - 64)]¹/³
