The function d/dx (f/g) = 2 gives the value of c as -4.

The denominator times the derivative of the numerator minus the numerator times the derivative of the denominator, all divided by the square of the denominator, is how the Quotient Rule defines the derivative of a quotient.

Given:

f(x) = 1/2x and g(x) = 1/ (3x + c)

Using Quotient rule

d/ dx (f/g)

= g f' - f g- / g²

So, d/dx ( 3x+c / 2x )

= [3x -1(3x+c)] / 2x²

= -c/ 2x²

Now out x= 1

Also, d/dx (f/g)= 2

-c/ 2 = 2

c= -4.

A 95% confidence interval for the estimated proportion of Canadians who refused the H1N1 vaccination can be calculated as follows:

Let p be the true proportion of Canadians who refused the vaccination.

The sample proportion is estimated by:

p_hat = 700 / 1000 = 0.7

The standard error of the sample proportion is:

SE = sqrt(p_hat * (1 - p_hat) / 1000) = sqrt(0.7 * 0.3 / 1000) = 0.0247

Using a normal approximation and a z-score of 1.96 (corresponding to a 95% confidence level), the confidence interval can be calculated as:

p_hat +/- z * SE = 0.7 +/- 1.96 * 0.0247 = [0.6511, 0.7489]

So, with 95% confidence, we can estimate that the true proportion of Canadians who refused the H1N1 vaccination lies between 0.6511 and 0.7489.

The number of pies made by cooking club to raise the money for field trip is equal to 14 .

Number of pies given by cafeteria = 2

Number of pieces each pie cut into = 4

Total pieces donated by cafeteria = 8

Total number of pieces sold by cooking club = 64

Number of pieces made by cooking club = 64 - 8

                                                                     = 56

Total number of pies made by cooking club to raise the money

= 56 / 4

= 14

The probability that Nomusa will not take two of the same type of sweet is 0.35

To find the probability that Nomusa will not take two of the same type of sweets, we need to find the total number of combinations of two sweets she can take, and then find the number of combinations where the two sweets are different.

First, let's find the total number of combinations of two sweets:

C(30, 2) = 435

This means there are 435 different combinations of two sweets she can take from her collection of 30 sweets.

Next, let's find the number of combinations where the two sweets are not the same:

C(18, 2) + C(7, 2) + C(5, 2) = 153

This means that there are 153 combinations where the two sweets are different fruit sweets, different aniseed sweets, or different mint sweets.

So, the probability that Nomusa will not take two of the same type of sweet is:

153 / 435 = 0.35

This means that there is a 35% chance that the two sweets she takes will not be the same type of sweet.

Answer: Perimeter because A=L X W and P= L+W+L+W

Step-by-step explanation:

Answer:

V = πr^2h = πr^2(2r) = 2πr^3

Volume of the cone: The volume of a cone with height h and base radius r is given by the formula V = (1/3)πr^2h. In this case, the height of the cone is equal to the radius of the hemisphere, so h = r. Substituting this into the formula, we have:

V = (1/3)πr^2h = (1/3)πr^2r = (1/3)πr^3

Volume of the hemisphere: To estimate the volume of the hemisphere, we'll average the volumes of the cylinder and cone.

So:V = (2πr^3 + (1/3)πr^3) / 2 = (5/3)πr^3 / 2 = (5/6)πr^3

So the volume of the hemisphere is approximately equal to (5/6)πr^3, where r is the radius of the hemisphere (and equal to the radius of the cylinder).

The probability of no two people having the same birthday at a dinner party with 25 people is 0.1389.

The probability of no two people having the same birthday is calculated using the Birthday Paradox. This paradox states that if there are n people gathered in a room, the probability that at least two people have the same birthday is 1 − (365/365) * (364/365) * (363/365) *...* ((365-n+1)/365).

For a dinner party with 25 people, the probability of no two people having the same birthday is 1 − (365/365) * (364/365) * (363/365) *...* (341/365) = 0.1389.

This means that there is a 13.89% chance that no two people at the dinner party have the same birthday. The probability of no two people having the same birthday at a dinner party with 25 people is 0.1389.

The perimeter of scale drawing of rectangular classroom floor is 42 inches.

Based on the mentioned information, let us first calculate the width of floor of classroom according to the scale drawing.

Length/width of original classroom floor = length/width of scale drawing

30/33 = 10/width

As we know, 1 foot = 12 inches

So, length = 360 inches and width = 396 inches

Width = (396 × 10)/360

Cancelling zero as it is common in both numerator and denominator

Width = 396/36

Performing division on Right Hand Side of the equation

Width = 11 inches

Perimeter of scale drawing = 2 (length + width)

Perimeter = 2( 10 + 11)

Performing addition

Perimeter = 2 × 21

Performing multiplication

Perimeter = 42 inches

Thus, perimeter of the rectangle is 42 inches.

Math deals with figures and their variants, calculations and parts, shapes and their regions, and locations places where they could be found. The term "function" describes the connection between a group various inputs, each of which has a corresponding output. A task is an association between inputs and outputs which each input results in a single, unique output. A domain and a codomain, or scope, are assigned toward each function. Functions are typically designated by the letter f. (x). The input is an x. Inside functions, one-to-one activities, many-to-one functions, within functions, and even on functions are the four main categories of functions that are available.

Step-by-step explanation:

The volume of a cone can be calculated as (1/3)πr^2h, so we can set that equal to 43.98:

(1/3)πr^2h = 43.98

Dividing both sides by (1/3)π:

r^2h = 43.98 * 3 / π

Solving for one of the variables in terms of the other requires choosing specific values for either radius or height. Here are two examples:

Example 1: Let's say r = 3.

Then

h = 43.98 * 3 / (π * 9) = 4.43

So one possible cone has height 4.43 and radius 3.

Example 2: Let's say h = 5.

Then

r^2 = 43.98 * 3 / (π * 5) = 25.51

So one possible cone has height 5 and radius 5.07.

Components of the unit vector are (cos(156), sin(156)) = (-0.41, 0.91). Drawing a vector with a positive y-component and an angle of 156 degrees with the x-axis in the xy plane will help you see it.

The unit vector has a positive y component and is located in the xy plane at a 156 degree angle to the x axis. Drawing a vector with a positive y-component and an angle of 156 degrees with the x-axis in the xy plane will help you visualise this. Components of the unit vector are (cos(156), sin(156)) = (-0.41, 0.91). This shows that the unit vector has both a positive y-component and a negative x-component. Since the unit vector's magnitude is 1, it has a length of 1, and it points in the same general direction as the 156-degree angle. In light of this, the unit vector is (-0.41, 0.91). Any vector with the same magnitude and direction as the unit vector but a different length can be represented by this vector.
