What proportion could you use to find the value of x?
A. 3/11=x/11
B. 3/x=x/11
C. 3+11/x=3/x
D. 11/x=x/11-3

Answer: 11.2

Step-by-step explanation:

a) d= k/r

=> 7= k/8

=> k= 7x8

therefore, k=56

b) d=k/r

=> d=56/ 5

so, d= 11.2

The value of d is 7 when r = 5.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

d is inversely proportional to r.

This can be written as,

d ∝ 1/r

d = k/r

Now,

d = 7 when r = = 8

This means.

7 = k/8

k = 56

Now,

Substituting r = 8.

d = 56/8

d = 7

Thus,

d = 7.

If the current loan balance is $79,000 and the house was recently appraised for $116,000, the equity in the house would be worth d) $37,000.

The home was bought at a price of $92,000 and a down payment of $11,000 was made. It is also given that the current loan balance is $79,000.

Also, the house was recently appraised for $116,000. We are asked to calculate the equity.

Now, equity is defined as the sum of money the owner of an item would receive if they sold it and all associated debts were settled is known as equity. For example, if one person owns a house which has a value of $100,000 and he has a mortgage of $40,000. Then, the equity in the home would be worth $60,000.

Here, in this question, the current debt is $79,000 and the current value of the house is $116,000.

So, the equity in the home would be:

                      Equity = 116,000 - 79000 = $37,000

The original amount of the bill was $7000 and the GST paid to the State Government by the CA is $1260.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

The bill services including the GST = 8260

The exact own price elasticity of demand is (A) -0.67.

The own price elasticity of demand measures the responsiveness of the quantity demanded to changes in price. It can be calculated using the formula:

epsilon = (dQ/dP) * (P/Q)

where dQ/dP is the derivative of the demand curve with respect to price and P/Q is the price elasticity of demand.

In this case, the demand curve is QD = 200 - 4P, so dQ/dP = -4. When P=$30, Q = 200 - 4 * 30 = 140. So,

epsilon = (-4) * (30/140) = -0.67

Hence, the exact own price elasticity of demand at P=$30 is -0.67, so the answer is A. -0.67.

The area of rhombus KLMN is 287.3 in²

A quadrilateral called a rhombus has four equal-length sides. The term "equilateral quadrilateral" refers to a quadrilateral whose sides all have equal lengths.

Given:

Since, the diagonals of a rhombus bisects each other at a right angle,

Let they bisect at O,

so, KM = 2MO = 2KO = 2×11.4 = 22.8 in

Thus, Δ KON is a right triangle,

Using Pythagoras theorem,

KN² = KO² + ON²

ON = √17²-11.4²

ON = 12.611 in

LN = 2×12.611

LN = 25.22 in

Then, Area of a rhombus = 1/2 × diagonal 1 × diagonal 2

Area = 1/2 × 25.22 × 22.8

Francis made an error in writing the explicit formula. The correct formula should be an = 4 * (1/4)⁽ⁿ⁻¹⁾, not an = 4 * (1/4)ⁿ⁻¹. The exponent should be (n-1), not just n, to correctly represent the sequence where the second term is 8 and the fourth term is 2.

To determine the error in Francis' formula, we need to apply it to the known terms of the sequence and see if it produces the correct values. For example, for the second term, n = 2, so using Francis' formula:

an = 4 * (1/4)⁽ⁿ⁻¹⁾ = 4 * (1/4)¹ = 4 * 1/4 = 1

But the second term of the sequence is 8, not 1. So the formula is incorrect.

Similarly, for the fourth term, n = 4, so using Francis' formula:

an = 4 * (1/4)⁽ⁿ⁻¹⁾ = 4 * (1/4)³ = 4 * 1/64 = 1/16

But the fourth term of the sequence is 2, not 1/16. So the formula is still incorrect.

Therefore, we can conclude that the formula written by Francis is not correct and needs to be corrected to accurately describe the sequence.

Where:

From the information provided in the graph above, we have the following data points on its line:

At data point (60, 10), a linear equation of this line can be calculated in point-slope form as follows:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

The observed data indicates that the null hypothesis should be rejected at a rejection criterion of 0.05. This means that the data supports the researcher's hypothesis that ants show handedness, and that they are more likely to turn into the right or left arms of a T-maze.

The researcher is interested in determining if ants show handedness.

The researcher is hypothesizing that if ants show handedness, they will be more likely to turn into the right or left arms of a T-maze.The researcher placed 20 ants into the maze and observed that 16 of the ants walked into the right arm and 3 into the left arm (one ant managed to crawl over the edge of the maze before it went down either of the arms). The probability that exactly 16 of the ants enter the right arm when the null hypothesis is true is 0.368. This is calculated using the binomial formula, P(x=16) = (20 choose 16) * (0.5)^16 * (0.5)^4, where 0.5 is the probability of each ant turning into either arm.Outcomes that are equally extraordinary or more extraordinary than the outcome observed under conditions in which the null hypothesis is true include: 17R, 3L; 18R, 2L; 19R, 1L; and 19R, OL.The probabilities associated with the outcomes identified in Problem 5 under conditions in which the null hypothesis is true are: 0.246 for 17R, 3L; 0.127 for 18R, 2L; 0.052 for 19R, 1L; and 0.026 for 19R, OL.The probability that an outcome as extraordinary or more extraordinary than the outcome observed would occur when the null hypothesis is true is 0.451. This is calculated by adding up the probabilities associated with each of the outcomes identified in Problem 5 (0.368 for 16R, 4L, 0.246 for 17R, 3L, 0.127 for 18R, 2L, 0.052 for 19R, 1L, and 0.026 for 19R, OL).

The observed outcome does not indicate that the null hypothesis should be rejected at a rejection criterion of 0.05 since the P value for the binomial test (0.451) is greater than 0.05. Therefore, we cannot reject the null hypothesis and conclude that ants do not show handedness.

Step-by-step explanation:

I can't really explain,But the equation is AX+BY=C

This is a position a win for the next player; the first player's winning move is to remove 2 chips from the pile with size 11, and if each player is allowed to remove at most 9 chips in a single move, then this is a P-position, and the previous player has won.

(a) The outcome of a game of Nim depends on the XOR (exclusive or) of the sizes of the piles. The XOR of 9, 10, 11, and 12 is 2, which means that this is a P-position (i.e., the previous player has won).

To determine the winning first move, we must find a combination of pile sizes that results in a new XOR of 0. One way to do this is to remove 2 chips from the pile with size 11, resulting in 9, 10, 9, and 12. The XOR of these new pile sizes is 0, which means that this is an N-position (i.e., the next player will win).

The first player's winning move is to remove 2 chips from the pile with size 11.

(b) The maximum number of chips that can be removed in a single move is 9, so the players are restricted in the amount they can remove. However, the outcome of the game still depends on the XOR of the pile sizes. In this case, the XOR of 9, 10, 11, and 12 is 2, which means that this is still a P-position and the previous player has won.

The winning first move, as described above, would still be to remove 2 chips from the pile with size 11.

We also know that J + T = 4 * (3 + 2), because they are working together to complete 4 lawns and it takes 3 hours for Taylor and 2 hours for Jamie to complete one lawn.

So we can substitute the first equation into the second equation:

2J + J = 4 * (3 + 2)

3J = 4 * 5

J = 4

The radius of earth is 6371 km.

Let's say the length of the piece of wood is L.

The diameter of the Earth is 2 times its radius

The radius of our planet, The Earth, is the distance from the center of the Earth to a point on or near its surface, and it ranges from nearly 6,378 km to nearly 6,357 km.

The diameter of a circle is the length of the line starting from one point on a circle to another point and passing through the center of the circle. It is equal to twice the radius of the circle. It is usually denoted by ‘d’ or ‘D’.

The diameter of the Earth is 2 times its radius, or 2 x 6371 km = 12742 km.

The diameter of the Earth is 12742 km / L times longer than the length of the piece of wood.
