Step-by-step explanation:

if the larger box are two times of those of the smaller box 8cf × 2=16 cf

Answer:

G

Step-by-step explanation:

a + b + c = 80

Express a and c in terms of b using the ratios in fractional form, that is

\(\frac{a}{b}\) = \(\frac{2}{3}\) ( cross- multiply )

3a = 2b ( divide both sides by 3 )

a = \(\frac{2}{3}\) b

\(\frac{b}{c}\) = \(\frac{3}{11}\) ( cross- multiply )

3c = 11b ( divide both sides by 3 )

c = \(\frac{11}{3}\) b

Substitute the values for a and c into the original equation

\(\frac{2}{3}\) b + b + \(\frac{11}{3}\) b = 80 ( multiply through by 3 to clear the fractions )

2b + 3b + 11b = 240 , that is

16b = 240 ( divide both sides by 16 )

b = 15 → G

The point (7,84) represents a precise location on a graph or coordinate plane.

A coordinate is a set of values that specifies the position or location of a point in a geometric space.

The point (7,84) represents a specific location on a graph or coordinate plane. The first number, 7, represents the point's position on the x-axis, which is a horizontal line that runs left to right. The second number, 84, represents the point's position on the y-axis, which is a vertical line that runs up and down. Together, the two numbers give us a precise location for the point.

In this situation, we don't have enough context to know what the point (7,84) represents. It could be the location of a city on a map, the amount of rainfall in inches on a specific day, or the price of a stock at a particular time. However, regardless of the situation, the point (7,84) is simply a specific location in a two-dimensional space that has been identified using coordinates.

What does the point (7,84) represent in the graph?​ And define the explanation for each value.

Answer:

14 $1 coin

12 quarter coin

Step-by-step explanation:

Let :

x = $1 dollar coin

y = $0.25 (1 quarter) coin

x + y = 26 - - - (1)

1x + 0.25y = 17 - - - - (2)

From (1) :

x = 26 - y

Put x = 26 - y in (2)

1(26 - y) + 0.25y = 17

26 - y + 0.25y = 17

-y + 0.25y = 17 - 26

-0.75y = - 9

Divide both sides by - 0.75

-0.75y /- 0.75 = - 9 / - 0.75

y = 12

Put y = 12 in (1)

x = 26 - 12

x = 14

(5,4)

Step-by-step explanation:

multiply each equation by the value that makes the coefficients of x opposite

(-1) · (4x + 6y) = (-1) · 44

4x + 2y = 28

simplify

-4x - 6y = -44

4x + 2y = 28

add the two equations together to eliminate x from the system

      -4x - 6y = -44

+      4x + 2y = 28

              -4y = -16

divide each term by -4

y = 4

substitute the value for y into one of the original equations, then solve for x

-4x - 6y = -44

-4x - 6(4) = -44

-4x - 24 = -44

     + 24   + 24

-4x = -20

divide by -4

x = 5

so, since x = 5 and y = 4 ....

the solution to the independent system of equations can be represented as a point.

The statement "Flexible exchange rates ..." is incomplete, and without further clarification, it is uncertain to determine whether it is true or false. A complete statement is required to provide a clear context for discussing the nature and implications of flexible exchange rates.

Flexible exchange rates refer to a system in which currency exchange rates are determined by market forces, such as supply and demand. Under this system, exchange rates fluctuate freely based on various economic factors, including inflation rates, interest rates, trade balances, and investor sentiment.

Flexible exchange rates offer advantages such as the ability to adjust to changing economic conditions and promote trade balance adjustments. They can also help absorb external shocks and enhance monetary policy autonomy. However, they may also introduce volatility and uncertainty in international trade and investment. To assess the accuracy of the statement, additional information or context is needed.

The sequence {an} converges to 1.

To determine if the sequence {an} converges, we can use the limit definition of convergence. Taking the limit as n approaches infinity of an, we have:

lim(n→∞) an = lim(n→∞) (1 − 1/6n) ^5n

Using the limit law for exponents, we can rewrite this as:

lim(n→∞) (1 − 1/6n) ^5n = [lim(n→∞) (1 − 1/6n)]^5n

Now we can use the limit law for products to separate the limit into two parts:

lim(n→∞) (1 − 1/6n) ^5n = [lim(n→∞) (1 − 1/6n)]^ [lim(n→∞) 5n]

The limit of (1 − 1/6n) as n approaches infinity is 1, so the first part simplifies to:

lim(n→∞) (1 − 1/6n) ^5n = 1^ [lim(n→∞) 5n]

The limit of 5n as n approaches infinity is infinity, so the second part is:

lim(n→∞) (1 − 1/6n) ^5n = 1^∞

This is an indeterminate form, so we need to use another method to find the limit. Taking the logarithm of both sides, we have:

ln(lim(n→∞) (1 − 1/6n) ^5n) = ln(1^∞)

Using the limit law for logarithms, we can rewrite this as:

lim(n→∞) 5n ln(1 − 1/6n) = ln(1)

The limit of ln(1 − 1/6n) as n approaches infinity is 0, so the left-hand side simplifies to:

lim(n→∞) 5n ln(1 − 1/6n) = 0

This means that the limit of the sequence {an} is 1, since:

lim(n→∞) an = lim(n→∞) (1 − 1/6n) ^5n = 1^∞ = e^0 = 1

Therefore, the sequence {an} converges to 1.

The correlation coefficient that best represents a moderate relationship showing fewer anxiety symptoms is a negative correlation coefficient.

In a negative correlation, as one variable increases, the other variable decreases. In the context of anxiety symptoms, a negative correlation would indicate that as one factor (e.g., a particular intervention, treatment, or activity) increases, the number or severity of anxiety symptoms decreases. This suggests a moderate relationship between the two variables, indicating that the higher the value of the independent variable, the lower the value of the dependent variable (in this case, fewer anxiety symptoms).

The correlation coefficient ranges from -1 to 1, with -1 representing a perfect negative correlation, 0 representing no correlation, and 1 representing a perfect positive correlation. A correlation coefficient close to -1, but not reaching -1, would be indicative of a moderate negative correlation and would best represent a moderate relationship showing fewer anxiety symptoms.

Drawn using the same scale, the shape of the normal curve H will be more spread out than the shape of the normal curve G.

Normal curve, or Gaussian distribution, is a curve that describes data form a variable that has infinite, or very large, number of possible values distributed among the population. It has a symmetric shape, and the distribution rises in the middle, and goes down to the left and to the right. The mean is equal to the mode and median and is located at the middle or top of the curve.

If two normal curves have the same mean, but different standard deviations, then the curve with the larger standard deviation will have a more spread out shape than the other.

If Normal curve H has a standard deviation of 10 and normal curve G has 5, but both has the same mean, then Normal curve H has a more spread out shape than the curve of normal curve G.

Given the information, political research selected 1100 voters from the town and discovered that 25% of the citizens supported the building.

Given sample percentage "p" = 25% = 0.25, this follows.

A campaign strategist decided to check the assertion that more than 22% of people support building based on available data.

Assuming Population Proportion 'P' = 22% = 0.22

Q = 1 - p = 1 - 0.22=0.78

Given the available information, a political strategist wishes to test the assertion that more citizens prefer building than 22%, thus we assume the null hypothesis is true.

Null Hypothesis: H₀: P > 0.22

Alternative hypothesis: H₁: P < 0.22

The inverse function of f(x) = 7tan(9x) is f⁻¹(x) = (1/9)arctan(x/7).

To find the inverse function of f(x) = 7tan(9x), we first need to understand the concept of inverse functions. An inverse function reverses the operation of the original function, meaning that if f(x) takes an input x and produces an output y, then the inverse function, denoted as f⁻¹(x), takes an input y and produces an output x.

Follow these steps to find the inverse function of f(x) = 7tan(9x):

1. Replace f(x) with y: y = 7tan(9x).
2. Swap x and y: x = 7tan(9y).
3. Solve for y: First, divide both sides by 7 to isolate the tangent function: x/7 = tan(9y).
4. Apply the arctangent (inverse tangent) function to both sides: arctan(x/7) = 9y.
5. Divide by 9 to solve for y: (1/9)arctan(x/7) = y.

Thus, the inverse function of f(x) = 7tan(9x) is f⁻¹(x) = (1/9)arctan(x/7). This inverse function takes an input x and returns the value of y such that the original function f(x) would map that y back to the input x. In other words, if f(x) = 7tan(9x) transforms a value x to a value y, then f⁻¹(x) = (1/9)arctan(x/7) will transform that same value y back to the original value x.
