3/5 is the fraction between the numbers 1/3 and 87/100

A number line is a graphical representation of numbers that can be used to understand and visualize numerical relationships. It is a straight line that extends infinitely in both directions and is usually drawn horizontally.

Writing the fractions as percentage:

1/3 * 100 = 33.3%

87/100 = 87%

This shows that the required number must be between 33.3% and 87%

From the given options:

3/5 * 100 = 3 * 20

3/5 * 100 = 60%

Hence the value in between the numbers 1/3 and 87/100 is 3/5

Answer: when the value of the dollar decreases, also when demand is high.

Step-by-step explanation: economics

the solution to the equation log2x + log4x + log16 = 7  the logarithms using the properties of Logarithms is x ≈ 53.408.

To solve the equation log2x + log4x + log16 = 7, we can simplify the logarithms using the properties of logarithms.

First, we can use the property loga + logb = log(ab) to combine the logarithms:

log2x + log4x + log16 = log(2x * 4x * 16)

Next, we simplify the expression inside the logarithm:

log(2x * 4x * 16) = log(32x^3)

Now, our equation becomes:

log(32x^3) = 7

To eliminate the logarithm, we can rewrite the equation in exponential form:

32x^3 = 10^7

Simplifying further:

32x^3 = 10,000,000

Now, we can solve for x by dividing both sides of the equation by 32:

x^3 = 10,000,000 / 32

x^3 = 312,500

To find the value of x, we take the cube root of both sides:

x = ∛312,500

x ≈ 53.408

Therefore, the solution to the equation log2x + log4x + log16 = 7 is x ≈ 53.408.

Paul will spend $1,382.4 constructing the patio.

Looking at the design, we can see that the length of the patio is represented by 8 cm, and the width is represented by 6.4 cm. To convert these measurements to feet, we multiply them by the scale factor:

Length = 8 cm * 3 ft/cm = 24 ft

Width = 6.4 cm * 3 ft/cm = 19.2 ft

The area of the patio is calculated by multiplying the length and width:

Area = Length * Width = 24 ft * 19.2 ft = 460.8 ft²

The cost to construct the patio is $3 per square foot. Therefore, Paul will spend:

Cost = Area * Cost per square foot = 460.8 ft² * $3/ft² = $1,382.4

The probability of getting Two Tails is 0.1 or 10%.

Let's assume that '2. Tails' appeared x times.

According to the given information, 'No Tail' appeared 3x times, and '1 Tail' appeared 2 × 3x = 6x times.

The total number of tosses is 360. We can express this information in an equation:

x + 3x + 6x = 360

Simplifying the equation:

10x = 360

x = 36

Now we know that '2. Tails' appeared 36 times, 'No Tail' appeared 3x = 3 × 36 = 108 times, and '1 Tail' appeared 6x = 6 × 36 = 216 times.

To find the probability of getting Two Tails, we divide the number of times '2. Tails' appeared by the total number of tosses:

Probability of Two Tails = Number of times '2. Tails' appeared / Total number of tosses

= 36 / 360

= 0.1

Therefore, the probability of getting Two Tails is 0.1 or 10%.

A. The function f is injective.

B. The function f is not surjective, as there are values in Q (e.g., y = 1) for which there is no corresponding x ∈ N.

To prove that the function f is injective, we need to show that if f(x) = f(y), then x = y.

Let f(x) = f(y). Then we have:

x / (1 + x) = y / (1 + y)

Cross-multiplying, we get:

x(1 + y) = y(1 + x)

x + xy = y + xy

Now, subtract xy from both sides:

x = y

Since x = y when f(x) = f(y), we can conclude that the function f is injective.

(b) To prove or disprove that the function f is surjective, we need to determine whether for every y ∈ Q, there exists an x ∈ N such that f(x) = y.

Consider the case where y = 1/2. We need to find x ∈ N such that:

f(x) = x / (1 + x) = 1/2

Cross-multiplying, we get:

2x = 1 + x

Subtract x from both sides:

x = 1

In this case, there exists an x ∈ N (x = 1) such that f(x) = 1/2. However, we need to consider all y ∈ Q. Let's try another case.

Consider the case where y = 1. There is no x ∈ N that satisfies the following equation:

f(x) = x / (1 + x) = 1

Cross-multiplying, we get:

x = 1 + x

Subtract x from both sides:

0 = 1

This is a contradiction, so there is no x ∈ N such that f(x) = 1. Therefore, the function f is not surjective, as there are values in Q (e.g., y = 1) for which there is no corresponding x ∈ N.

The horizontal distance between the base of the ladder and the wall is approximately 16.2 feet.

To answer the question, we need to use trigonometry. In this case, we can use the sine function, which relates the opposite side of a right triangle to its hypotenuse. In this case, the ladder is the hypotenuse, and the horizontal distance between the base of the ladder and the wall is the opposite side.

The angle formed by the ladder and the ground is the angle of interest.

Let x be the horizontal distance between the base of the ladder and the wall. Then, using the sine function, we have:

sin(64 degrees) = x/18

Multiplying both sides by 18, we get:

x = 18 sin(64 degrees) ≈ 16.2 feet

Therefore, the horizontal distance between the base of the ladder and the wall is approximately 16.2 feet.

It is important to note that when using trigonometry, we need to use the appropriate trigonometric function depending on the sides and angles we are given. In this case, we were given the hypotenuse and the angle opposite the horizontal distance, so we used the sine function.

The 90% confidence interval for the population proportion of adults who made a New Year's resolution is approximately 0.523 to 0.554, while the 95% confidence interval is approximately 0.517 to 0.559.

To construct 90% and 95% confidence intervals for the population proportion based on the survey results of 1220 adults who made a New Year's resolution out of a total of 2267 adults, we can use the formula for confidence intervals for a proportion.

Calculate the sample proportion:

The sample proportion is the number of individuals who made a New Year's resolution divided by the total sample size.

Sample proportion [tex]\hat{p}[/tex]  = 1220 / 2267 = 0.5386

Determine the standard error:

The standard error measures the variability of the sample proportion and is calculated using the formula:

Standard error[tex](SE) = \sqrt{((\hat{p } \times (1 - \hat{p})) / n) }[/tex]

where n is the sample size.

Calculate the margin of error:

The margin of error represents the range within which the true population proportion is likely to fall.

It depends on the desired level of confidence and is calculated by multiplying the standard error by the appropriate critical value from the standard normal distribution.

For a 90% confidence interval, the critical value is 1.645.

For a 95% confidence interval, the critical value is 1.96.

Margin of error = Critical value [tex]\times[/tex] Standard error

Construct the confidence intervals:

The confidence interval is calculated by adding and subtracting the margin of error from the sample proportion.

For the 90% confidence interval: [tex]\hat{p}[/tex] ± Margin of error

For the 95% confidence interval: [tex]\hat{p}[/tex]  ± Margin of error

Using these steps and the provided information, we can construct the confidence intervals for the population proportion.

We are given that;

tank measurement is 13*8*17

Now,

A cube is a three-dimensional representation of a square. it has 6 faces 2 on the bottom and top, 4 on the sides faces.

To find the volume of water in the tank when it is upright. To do this, you multiply the depth of water by the area of the base:

Volume = Depth * Area Volume = 9 cm * (13 cm * 8 cm) Volume = 936 cm^3

This volume does not change when you put the tank on its side. However, the area of the base does change. Depending on which side you put the tank on, the area of the base will be either 13 cm by 17 cm or 8 cm by 17 cm. Let’s assume you put the tank on its longer side, so that the area of the base is 13 cm by 17 cm.

Now, you can find the depth of water by dividing the volume by the area:

Depth = Volume / Area Depth = 936 cm^3 / (13 cm * 17 cm) Depth= 4.2 cm

To simplify the expression: 3 1/5x + 10 7/9 - 2 2/5x - 10 8/9, we need to perform the addition and subtraction of the terms.

First, let's focus on the x terms: 3 1/5x - 2 2/5x.

The whole numbers can be treated as fractions with a denominator of 1. Thus, we have:

(3 1/5)x - (2 2/5)x.

To perform the subtraction, we need to find a common denominator for the fractions involved, which is 5.

(3 1/5)x - (2 2/5)x = (16/5)x - (12/5)x.

Now we can subtract the terms:

(16/5)x - (12/5)x = (16 - 12)/5x.

Let x represent the cost per pound of the espresso coffee beans and

y represent the cost per pound of the vanilla coffee beans.
