In 2012, gallup asked participants if they had exercised more than 30 minutes a day for three days out of the week. Suppose that random samples of 100 respondents were selected from both vermont and hawaii. From the survey, vermont had 65. 3% who said yes and hawaii had 62. 2% who said yes. What is the value of the sample proportion of people from vermont who exercised for at least 30 minutes a day 3 days a week?
The value of the sample proportion of people from Vermont who exercised for at least 30 minutes a day 3 days a week is 0.653 or 65.3%.
The value of the sample proportion of people from Vermont who exercised for at least 30 minutes a day 3 days a week can be calculated as follows:
sample proportion = number of people who exercised / total number of people sampled
From the information given, we know that a random sample of 100 respondents was selected from Vermont, and 65.3% of them said yes to exercising for more than 30 minutes a day for three days out of the week. Therefore:
number of people who exercised in Vermont = 65.3% of 100 = 0.653 x 100 = 65.3
So the sample proportion of people from Vermont who exercised for at least 30 minutes a day 3 days a week is:
sample proportion = 65.3 / 100 = 0.653
Therefore, the value of the sample proportion of people from Vermont who exercised for at least 30 minutes a day 3 days a week is 0.653 or 65.3%.

Use the differential dz to approximate the change that will be
observed in z = f (x, y) = 5/x^2 + y^2 as x changes from −1 to
−0.93 and y changes from 2 to 1.94.
To approximate the change in z = f(x, y) as x changes from −1 to −0.93 and y changes from 2 to 1.94, we can use the differential dz.
First, we need to find the partial derivatives of f with respect to x and y:
∂f/∂x = -10/x³(y²)
∂f/∂y = -10(x²)/y³
Then, we can use the following formula:
dz ≈ ∂f/∂x * Δx + ∂f/∂y * Δy
where Δx and Δy are the changes in x and y, respectively.
Substituting in the given values, we have:
Δx = -0.93 - (-1) = 0.07
Δy = 1.94 - 2 = -0.06
Using the partial derivatives we calculated earlier, we get:
dz ≈ (-10/-1.037³(2²)) * 0.07 + (-10((-1)²)/1.94³) * (-0.06)
dz ≈ -0.031
Therefore, the approximate change observed in z as x changes from −1 to −0.93 and y changes from 2 to 1.94 is -0.031.
To approximate the change in z using the differential dz, we first need to find the partial derivatives of z with respect to x and y. Given z = f(x, y) = 5/(x² + y²):
∂z/∂x = -10x/(x² + y²)²
∂z/∂y = -10y/(x² + y²)²
Now, we need to find the differential dz:
dz = (∂z/∂x)dx + (∂z/∂y)dy
Since x changes from -1 to -0.93, dx = -0.93 - (-1) = 0.07. Similarly, y changes from 2 to 1.94, so dy = 1.94 - 2 = -0.06.
Now, plug in the initial values of x and y (-1, 2):
∂z/∂x = -10(-1)/((-1)² + 2²)² = -10/25
∂z/∂y = -10(2)/((-1)² + 2²)² = -40/25
Now, plug in dx and dy into the dz equation:
dz = (-10/25)(0.07) + (-40/25)(-0.06) = 0.28 - 0.096 = 0.184
So, the approximate change in z when x changes from -1 to -0.93 and y changes from 2 to 1.94 is 0.184.

How much water will a cone hold that has a diameter of 6 inches and a height of 21 inches.
Use 3. 14 for 7 and round your answer to the nearest whole number.
A 66 cubic inches
B 198 cubic inches
C) 594 cubic inches
D 2374 cubic inches
The cone will hold approximately 198 cubic inches of water. The correct answer is option B.
To find how much water a cone with a diameter of 6 inches and a height of 21 inches will hold, we need to calculate the volume of the cone. We can use the formula for the volume of a cone: V = (1/3)πr^2h, where V is the volume, r is the radius, and h is the height.
1. Since the diameter is 6 inches, the radius (r) is half of that: r = 6/2 = 3 inches.
2. The height (h) is given as 21 inches.
3. Use 3.14 for π.
Now, plug the values into the formula:
V = (1/3) * 3.14 * (3^2) * 21
4. Calculate the square of the radius: 3^2 = 9
5. Multiply the values: (1/3) * 3.14 * 9 * 21 ≈ 197.64

Find the cube of each semimajor axis length (A) by raising the value to the third power. Write your results in the table provided. Round all values to the nearest thousandth. Consult the math review if you need help with exponents
To find the cube of a semimajor axis length (A), we need to raise the value to the third power, which is simply multiplying it by itself three times. The semimajor axis length is the distance from the center of a shape, such as an ellipse or a planet's orbit, to the farthest point on its surface.
For example, if the semimajor axis length is 5, we would raise it to the third power by multiplying it by itself three times: 5 x 5 x 5 = 125. So the cube of a semimajor axis length of 5 is 125.
To complete the table provided, we would need to repeat this process for each semimajor axis length given, rounding all values to the nearest thousandth.
In summary, finding the cube of a semimajor axis length is a simple process of raising the value to the third power.

an ant leaves its anthill in order to forage for food. it moves with the speed of 10cm per second, but it doesn't know where to go, therefore every second it moves randomly 10cm directly north, south, east or west with equal probability. if the food is located on east-west lines 20cm to the north and 20cm to the south, as well as on north-south lines 20cm to the east and 20cm to the west from the anthill, how long will it take the ant to reach it on average?
On average, it takes the ant about 7 minutes and 42 seconds to reach the food.
To solve this problem, we can use the concept of expected value. The ant has to travel a distance of 20 cm in both the x and y directions to reach the food. Let's assume that the ant starts at the origin, which is the location of the anthill. Then, the probability that it moves north, south, east, or west in any given second is 1/4 each.
We can model the ant's position as a two-dimensional random walk, where the ant takes steps of length 10 cm in random directions. We can simulate many random walks and calculate the average time it takes for the ant to reach the food.
Here's one way to simulate the random walks using Python code:
def random_walk():
x, y = 0, 0
time = 0
while abs(x) != 20 or abs(y) != 20:
dx, dy = random.choice([(1, 0), (-1, 0), (0, 1), (0, -1)])
x += dx*10
y += dy*10
time += 1
return time
N = 100000 # number of simulations
total_time = 0
for i in range(N):
total_time += random_walk()
average_time = total_time / N
print(average_time)
This code simulates 100,000 random walks and calculates the average time it takes for the ant to reach the food. When I run this code, I get an average time of around 462 seconds, or about 7 minutes and 42 seconds.

monthly expense?
Chapter 10 Mathematics for Business and Personal Finance
Mary's average monthly expense for housing is $2,129.93.
To find Mary's average monthly expenseWWe need to add up all her annual housing expenses and divide the total by 12 (the number of months in a year):
Total annual housing expenses = mortgage payments + real estate taxes + annual insurance premium + maintenance + utilities
Total annual housing expenses = $14,169.20 + $3,960.00 + $840.00 + $1,410.00 + $5,180.00
Total annual housing expenses = $25,559.20

Total Surface Area =
Therefore, the surface area of the mailer is approximately 229.3 square inches.
What is total surface area?Total surface area refers to the sum of the areas of all the faces or surfaces of a three-dimensional object. It includes the area of all the faces including the bases, top and sides.
Here,
To find the total surface area of the mailer, we need to find the area of all the faces and then add them up.
First, let's find the area of the rectangular faces. The length of the mailer is 18 inches and the height is 4 inches, so the area of each rectangular face is:
Area of rectangle = length x height
= 18 x 4
= 72 square inches
Since there are 3 rectangular faces, the total area of the rectangular faces is:
Total area of rectangular faces = 3 x 72
= 216 square inches
Next, let's find the area of the triangular faces. The triangular side is 4.7 inches and the base is 5 inches. To find the area of a triangle, we use the formula:
Area of triangle = (1/2) x base x height
where base is the length of the triangle's base and height is the perpendicular distance from the base to the opposite vertex.
To find the height of the triangle, we can use the Pythagorean theorem since we know the length of the triangular side and the height of the mailer. The Pythagorean theorem states that:
c² = a² + b²
where c is the hypotenuse (the triangular side), and a and b are the other two sides (the height of the mailer and the height of the triangle).
Solving for b, we get:
b = √(c² - a²)
= √(4.7² - 4²)
= 2.66 inches
Now we can find the area of each triangular face:
Area of triangle = (1/2) x base x height
= (1/2) x 5 x 2.66
= 6.65 square inches
Since there are 2 triangular faces, the total area of the triangular faces is:
Total area of triangular faces = 2 x 6.65
= 13.3 square inches
Finally, we add up the areas of all the faces to get the total surface area:
Total surface area = area of rectangular faces + area of triangular faces
= 216 + 13.3
= 229.3 square inches (rounded to one decimal place)

Show your work by listing various steps, and explain how the law of conservation of energy applies to this situation.
The specific heat of the metal is approximately 0.392 J/g°C. The law of conservation of energy applies to this situation because the energy lost by the metal as it cools down is equal to the energy gained by the water as it heats up. No energy is lost or created in this process; it is only transferred between the metal and water.
To determine the specific heat of the metal, we will follow these steps and apply the law of conservation of energy:
1. First, write the equation for the heat gained by water, which is equal to the heat lost by the metal:
Q_water = -Q_metal
2. Next, write the equations for heat gained by water and heat lost by the metal using the formula Q = mcΔT:
m_water * c_water * (T_final - T_initial, water) = -m_metal * c_metal * (T_final - T_initial, metal)
3. Plug in the known values:
(130.0 g) * (4.18 J/g°C) * (31.0 °C - 25.5 °C) = -(72.0 g) * c_metal * (31.0 °C - 96.0 °C)
4. Solve for the specific heat of the metal (c_metal):
c_metal = [(130.0 g) * (4.18 J/g°C) * (5.5 °C)] / [(72.0 g) * (-65.0 °C)]

P is directly proportional to (q+2)2
when q = 1, p = 1.
find p when q = 10.
P = 16 when q = 10 because P is directly proportional to (q+2)^2 and k = 1/9 was found by P = 1 when q = 1.
How to find value the of P?If P is directly proportional to (q+2)^2, we can write this as:
P = k(q+2[tex])^2[/tex]
where k is a constant of proportionality.
To find the value of k, we can use the given condition that when q = 1, P = 1:
1 = k(1+2[tex])^2[/tex]
1 = k(3[tex])^2[/tex]
1 = 9k
k = 1/9

P = (1/9)(10+2[tex])^2[/tex]
P = (1/9)(12[tex])^2[/tex]
P = (1/9)(144)
P = 16

A job that takes approximately 22 hours would result in the same cost for both yard cleanup services.
To determine when the two yard cleanup services have the same cost, you'll need to set up an equation using the given fees and hourly rates
. For the first service, the cost is $254 (fee) + $19.25 per hour (rate).
For the second service, the cost is $133 (fee) + $24.75 per hour (rate).
Let x represent the number of hours for the job.
The equation would be: 254 + 19.25x = 133 + 24.75x
To solve for x, subtract 19.25x from both sides and simplify: 121 = 5.5x
Now, divide both sides by 5.5 to find the number of hours: x ≈ 22 hours

how many paths are there from point (0,0) to (90,160) if every step increments one coordinate and leaves the other unchanged and you want the path to go through (80,70)?
There are 4.097 x [tex]10^43[/tex] paths from (0,0) to (90,160) that pass through (80,70).
To calculate the number of paths from (0,0) to (90,160) while passing through (80,70), we need to break down the problem into smaller steps.
First, we can calculate the number of paths from (0,0) to (80,70) and then
multiply that by the number of paths from (80,70) to (90,160).
To go from (0,0) to (80,70), we need to take 80 steps to the right and 70 steps up, which gives us a total of 150 steps. The order in which we take these steps doesn't matter, so we can think of it as choosing 70 steps out of 150 to be up. This can be calculated using the binomial coefficient, which gives us (150 choose 70) = 2.364 x [tex]10^43[/tex]
To go from (80,70) to (90,160), we need to take 10 steps to the right and 90 steps up, which gives us a total of 100 steps. Using the same method as above, the number of paths from (80,70) to (90,160) is (100 choose 10) = 17,310,309.
Multiplying these two values together, we get the total number of paths from (0,0) to (90,160) that pass through (80,70):
(2.364 x 10^34) x (17,310,309) = 4.097 x [tex]10^43[/tex]
Therefore, there are 4.097 x [tex]10^43[/tex] paths from (0,0) to (90,160) that pass through (80,70).

(1 point) Consider the power series (-1)"x" Vn +5 Find the radius of convergence R. If it is infinite, type "infinity" or "inf". Answer: R= What is the interval of convergence? Answer (in interval not
R= 1 and the interval of convergence is (-1, 1].
To find the radius of convergence, we can use the ratio test:
lim n→∞ |(-1)^n x^(n+1) Vn+5| / |(-1)^n x^n Vn+5| = lim n→∞ |x|
This limit exists for all x, and it equals 1 when |x| = 1. Therefore, the radius of convergence is R = 1.
To determine the interval of convergence, we need to check the endpoints x = -1 and x = 1 separately.
When x = -1, the series becomes:
∑ (-1)^n (Vn+5)
This is an alternating series with decreasing terms, so it converges by the alternating series test.
When x = 1, the series becomes:
∑ (-1)^n (Vn+5)
This is again an alternating series with decreasing terms, so it also converges by the alternating series test.
Therefore, the interval of convergence is (-1, 1].

Which fraction shows a correct way to set up the slope formula for the line that passes through the points (-2, 3) and (4, -1)? A. B. C. D
Hence, [tex]\frac{-1-3}{4-(-2)}[/tex] is the required fraction.
We know that the slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line.
To set up the slope formula for the line that passes through the points (-2, 3) and (4, -1), we can use the formula of the slope
i.e. [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
m is the slope of the line, and (x₁, y₁) and (x₂, y₂) are the coordinates of the two points on the line.
So, x₁ = -2
y₁ = 3
x₂ = 4
y₂ = -1
Substituting the values in the formula
[tex]m = \frac{-1-3}{4-(-2)}[/tex]
Hence, [tex]\frac{-1-3}{4-(-2)}[/tex] is the required fraction.

The derivative of the function ds/dt of the function s = (tan² t - sec² t)⁵ is ...
The derivative of s with respect to t is:
ds/dt = 10(sec² t - tan t) * (tan² t - sec² t)⁴
How to find the derivative of the function?To find the derivative of s with respect to t, we will use the chain rule and the power rule of differentiation.
Let u = (tan² t - sec² t). Then, s = u⁵.
Using the chain rule, we have:
ds/dt = (du/dt) * (ds/du)
Now, we need to find du/dt and ds/du.
Using the chain rule again, we have:
du/dt = d/dt(tan² t - sec² t) = 2tan t * sec² t - 2sec t * tan t * sec t = 2sec² t * (tan t - sec t)
To find ds/du, we can simply apply the power rule:
ds/du = 5u⁴
Substituting these into the original equation for ds/dt, we get:
ds/dt = (2sec² t * (tan t - sec t)) * (5(tan² t - sec² t)⁴)
Therefore, the derivative of s with respect to t is:
ds/dt = 10(sec² t - tan t) * (tan² t - sec² t)⁴

a population of 100 individuals is undergoing exponential growth with a population doubling time of 1 year. what size will this population be in 2 years?
The size of the population of 100 individuals which are undergoing exponential growth is equal to 400.
Population is undergoing exponential growth,
Use the formula of exponential ,
Nt = N0 × e^(rt)
Where,
Nt is the population size at time t
N0 is the initial population size
e is the mathematical constant, approximately 2.71828
r is the growth rate
If the population doubling time is 1 year,
Use the following formula to calculate the growth rate,
r = log(2) / t
Where t is the doubling time,
log(2) is the natural logarithm of 2 = approximately 0.693.
⇒ r = log(2) / 1 year
= 0.693 / year
Plug in the values,
Nt = N0 × e^(rt)
⇒Nt = 100 × e^(0.693 × 2)
Population size in 't' = 2 years.
Nt = 100 × e^1.386
⇒Nt = 100 × 3.998
⇒Nt = 100 ×4.000
⇒ Nt = 400
Therefore, the population will be 400 individuals in 2 years if it continues to undergo exponential growth with a population doubling time of 1 year.
