Answer:

The circumference of the circle is approximately 19.8 centimetres.

Step-by-step explanation:

If the square has an area of 40 square centimetres, that means that the side length of the square is √40, or 2√10

The side length will be the diameter of the circle. Which is all we need to find its circumference.  The circumference of a circle is equal to pi times its diameter, so we say:

c = πd

c = 3.14 × 2√10

c = 6.28√10

c = 6.28 × 3.16

c = 19.8

The approximations for the values of f at the given points are:

To find the linear approximation of the function f(x,y,z) = x²/(y²z²) at point (3,2,6), we need to compute the partial derivatives of f with respect to x, y, and z at that point:

fx(x,y,z) = 2x/(y²z²), so fx(3,2,6) = 2/(2² * 6²) = 1/54

fy(x,y,z) = -2x²/(\(y^3\)z²), so fy(3,2,6) = -18/64

fz(x,y,z) = -2x²/(y²\(z^3\)), so fz(3,2,6) = -2/\(6^3\) = -1/108

The linear approximation of f at point (3,2,6) is given by:

L(x,y,z) = f(3,2,6) + fx(3,2,6)(x-3) + fy(3,2,6)(y-2) + fz(3,2,6)*(z-6)

L(x,y,z) = 9/144 + (1/54)(x-3) - (18/64)(y-2) - (1/108)*(z-6)

To approximate the value of f at points (3.02, 1.97, 5.99), we can use the linear approximation L:

f(3.02, 2, 6) ≈ L(3.02, 2, 6) = 0.0878

f(1.97, 2, 6) ≈ L(1.97, 2, 6) = 0.0545

f(3, 2, 5.99) ≈ L(3, 2, 5.99) = 0.1387

Therefore, the approximations for the values of f at the given points are:

When we have two large independent samples from two populations, the difference in the two sample means will follow an approximate normal distribution.

This is due to the central limit theorem, which states that when we have a large enough sample size (typically, greater than 30), the distribution of the sample means will be normal regardless of the underlying distribution of the populations. As the two samples are independent, the difference in means will also be independent. Therefore, we can use the normal distribution to estimate the probability of observing a certain difference in means. It is important to note that this approximation may not hold for small sample sizes, and the underlying distributions of the populations can also impact the shape of the distribution. We can say that the normal distribution approximation is widely used in statistics and hypothesis testing, making it an essential concept for understanding and interpreting data.

The volume of the wedge is π/8 cubic meters.

To find the volume of the wedge, follow these steps:
1. First, find the radius of the tree by dividing the diameter by 2.

Since the diameter is 2 meters, the radius (r) is 1 meter.
2. The angle of inclination of the second cutting plane is given as 45 degrees.

Since a full circle is 360 degrees, find the fraction of the circle that the wedge represents by dividing 45 by 360.

This gives us 45/360 = 1/8.
3. The volume of a cylinder can be calculated using the formula V = π\(r^2h,\)

where r is the radius and h is the height.

In this case, the height of the wedge (h) is equal to the radius (r), which is 1 meter.

So, the volume of the whole cylinder (tree) would be V = π\((1^2)(1)\)

= π cubic meters.
4. Now, multiply the volume of the whole cylinder by the fraction representing the wedge (1/8) to find the volume of the wedge: (1/8) × π = π/8 cubic meters.

We will get that the angle theta is:

θ = β/2

Remember that the sum of the interior angles of any triangle must be equal to 180°.

Now, looking at the triangle in the left, we can see that the top angle is equal to:

180 - 2α

The right angle is equal to:

180 - 2β

And the left angle is α

Then we can write:

α + (180 - 2α) + (180 - 2β) = 180

-α - 2β = -180

α = 180 - 2β

Now we can go to the other triangle, where theta is, and write:

α + β + 2θ = 180

Replacing what we found above, we get:

180 - 2β + β + 2θ = 180

-β + 2θ = 0

θ = β/2

IQ scores have a mean of 100 and a standard deviation of 15. Greg has an IQ of 127. (a) The difference between Greg's IQ and the mean is 27. (b) Greg's IQ score of 127 corresponds to a z-score of approximately 1.8.

(a) The difference between Greg's IQ and the mean IQ can be calculated by subtracting the mean from Greg's IQ score. In this case, the mean is 100 and Greg's IQ is 127. Therefore, the difference is:

Greg's IQ - Mean IQ = 127 - 100 = 27

(b) To convert Greg's IQ score to a z-score, we can use the formula:

z = (x - mean) / standard deviation

where x is the individual score, mean is the population mean, and standard deviation is the population standard deviation.

In this case, Greg's IQ score is 127, the mean is 100, and the standard deviation is 15. Plugging these values into the formula, we get:

z = (127 - 100) / 15 = 27 / 15 ≈ 1.8

Answer:

The basketball game sold 439  adult tickets and  858 student tickets.

Step-by-step explanation:

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is, in the systems of equations, one must look for the values ​​of the unknowns, with which when replacing, they must give the solution proposed in both equations.

Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $3,047  was collected on the sale of 1,291 tickets.

With "x" the number of adult tickets sold and "y" the number of student tickets sold, you have the following system of equations:

\(\left \{ {{x+y=1291} \atop {5*x+1*y=3047}} \right.\)

Through the substitution method, you must solve for one of the unknowns in one of the equations and substitute its value in the following one: in this case you solve for the variable y from the first equation:

y=1291 -x

and you replace in the second equation:

5*x + 1291 - x= 3047

Solving, you get:

5*x-x= 3047 - 1291

4*x= 1756

x= 1756÷4

x=439

Replacing this value in the expresion y=1291 -x you get:

y=1291 -439

y= 858

1. After 2 days, both Adam and Brodie will have the same amount of money.

2. The number is -6.

1. Let's represent the number of days as 'x'.

Adam starts with $2 and saves $2 each day, so his total amount of money after 'x' days is 2 + 2x.

Brodie starts with $8 and spends $1 each day, so his total amount of money after 'x' days is 8 - x.

We want to find the number of days when both Adam and Brodie have the same amount of money:

2 + 2x = 8 - x

Adding 'x' to both sides, we get:

2 + 3x = 8

Subtracting 2 from both sides, we get:

3x = 6

Dividing both sides by 3, we get:

x = 2

2. Let's represent the number as 'x'.

The number increased by 8 is equal to twice the same number increased by 7:

x + 8 = 2(x + 7)

Expanding the equation, we get:

x + 8 = 2x + 14

Subtracting 'x' from both sides, we get:

8 = x + 14

Subtracting 14 from both sides, we get:

-6 = x

In the first problem, we set up equations to represent the amount of money Adam and Brodie have after 'x' days. By equating the expressions and solving for 'x', we found that it takes 2 days for both of them to have the same amount of money. Therefore, the correct answer is D. x + 8 = 2x + 7.

In the second problem, we set up an equation to represent the relationship between a number and twice that number increased by 7. By solving the equation, we found that the number is -6. Therefore, the correct answer is D. x + 8 = 2x + 7.

Step-by-step explanation:

The point of diminishing returns is (20.98, 21247.3).

The point of diminishing returns occurs when the marginal cost of producing an extra unit of output exceeds the marginal revenue generated from selling that unit. Mathematically, it is the point at which the derivative of the production function equals zero and the second derivative is negative.

Given the polynomial function N(x) of degree 3, we can find the point of diminishing returns by finding the critical points where the first derivative equals zero and evaluating the second derivative at those points.

The derivative of N(x) is N'(x) = -18x² + 360x + 2250. To find the critical points, we set N'(x) = 0:

0 = -18x² + 360x + 2250

Dividing by -18 simplifies the equation:

0 = x² - 20x - 125

Using the quadratic formula, we find the solutions to the equation:

x₁,₂ = (20 ± √(20² - 4(1)(-125))) / 2(1)

x₁,₂ = 10 ± 5√5

Thus, the two critical points of N(x) are at x = 10 - 5√5 and x = 10 + 5√5.

To determine the point of diminishing returns, we evaluate the second derivative N''(x) = -36x + 360 at these critical points:

N''(10 - 5√5) = -36(10 - 5√5) + 360 ≈ -264.8

N''(10 + 5√5) = -36(10 + 5√5) + 360 ≈ 144.8

From the evaluations, we find that N''(10 + 5√5) is negative while N''(10 - 5√5) is positive. Therefore, the point of diminishing returns corresponds to x = 10 + 5√5.

To find the corresponding y-coordinate (N(10 + 5√5)), we can substitute the value of x into the original function N(x).

Hence, the point of diminishing returns is approximately (20.98, 21247.3).

\(\frac{8}{27}\) is the probability that a player draws out two tiles of the same color assuming they are drawing one tile from each bag.

Step-by-step explanation:

In each bag there are red, green, and blue tiles, meaning that no matter which color is pulled out first there is always some probability that the second tile will be the same color. So, we can set up three possible outcomes:

Red: The player pulls out a red tile first. This has a \(\frac{1}{9}\) probability of happening. Then in order to succeed for the problem, the next tile also needs to be red which has a \(\frac{6}{12}\) probability attached to it. \(\frac{1}{9}\) × \(\frac{6}{12}\)=\(\frac{1}{18}\) probability of happening.

Green: There is a \(\frac{5}{9}\) probability of the player pulling out a green tile first. In this case we want to calculate the probability of the second tile being green, which would be \(\frac{4}{12}\). \(\frac{5}{9}\)×\(\frac{4}{12}\)=\(\frac{5}{27}\).

Blue: There is a \(\frac{3}{9}\) probability of the first tile being blue in which case we are hoping for the second tile to be blue as well. The probability of the second tile being blue is \(\frac{2}{12}\) on its own, and them both being blue is  \(\frac{3}{9}\)×\(\frac{2}{12}\)=\(\frac{1}{18}\)

Adding \(\frac{1}{18}\)+\(\frac{1}{18}\)+\(\frac{5}{27}\) we get the answer \(\frac{8}{27}\).

Option C, y = e^(x+y) + x^2 + 3x - 2, requires the use of implicit differentiation to find dy/dx.

The expression that requires the use of implicit differentiation to find dy/dx is option C: y = e^(x+y) + x^2 + 3x - 2.

Implicit differentiation is a technique used to differentiate equations where the dependent variable y is not explicitly expressed as a function of x. It involves differentiating both sides of the equation with respect to x, treating y as an implicit function of x.

Let's apply implicit differentiation to option C:

Starting with the equation: y = e^(x+y) + x^2 + 3x - 2

To find dy/dx, we differentiate both sides of the equation with respect to x:

d/dx(y) = d/dx(e^(x+y) + x^2 + 3x - 2)

Using the chain rule on the right side of the equation, we get:

dy/dx = d/dx(e^(x+y)) + d/dx(x^2) + d/dx(3x) - d/dx(2)

The derivative of e^(x+y) with respect to x requires the use of implicit differentiation. We treat y as an implicit function of x and apply the chain rule:

d/dx(e^(x+y)) = e^(x+y) * (1 + dy/dx)

The derivatives of the remaining terms on the right side are straightforward:

d/dx(x^2) = 2x

d/dx(3x) = 3

d/dx(2) = 0

Substituting these derivatives back into the equation, we have:

dy/dx = e^(x+y) * (1 + dy/dx) + 2x + 3

Next, we isolate dy/dx on one side of the equation by moving the term involving dy/dx to the left side:

dy/dx - e^(x+y) * dy/dx = e^(x+y) + 2x + 3

Factoring out dy/dx, we get:

(1 - e^(x+y)) * dy/dx = e^(x+y) + 2x + 3

Finally, we solve for dy/dx:

dy/dx = (e^(x+y) + 2x + 3) / (1 - e^(x+y))
