The equation that describes the hanger is y = x + 1.b-This line will represent the equation y = x + 1.c. The equation for the first hanger is y = x + 1.

Equation is a mathematical statement that expresses the equality of two expressions by using symbols. It typically consists of an equals sign (=) and two expressions that are related by the equals sign. Equations are used to describe the relationship between different variables, such as the area of a circle or the speed of a moving object. Equations are also used to solve problems, to make predictions, or to reveal patterns or trends.

a. The equation that describes the hanger is y = x + 1. This equation states that the y-coordinate (height of the hanger) is always 1 unit greater than the x-coordinate (width of the hanger).

b. To find x, I will draw more hangers to represent each step of the process. For the first hanger, I will draw a line with a y-intercept of 1 and a slope of 1. This line will represent the equation y = x + 1.

For the second hanger, I will draw a line with a y-intercept of 1 and a slope of 2. This line will represent the equation y = 2x + 1.

For the third hanger, I will draw a line with a y-intercept of 1 and a slope of 3. This line will represent the equation y = 3x + 1.

The reason I chose to draw each hanger with a y-intercept of 1 is to represent the constant value of 1 in each equation. The slope of each hanger is increased by 1 from the previous hanger to represent the coefficient of x in each equation.

c. The equation for the first hanger is y = x + 1. This equation matches the hanger because the y-intercept is 1 and the slope is 1.

The equation for the second hanger is y = 2x + 1. This equation matches the hanger because the y-intercept is 1 and the slope is 2.

The equation for the third hanger is y = 3x + 1. This equation matches the hanger because the y-intercept is 1 and the slope is 3.

The values of  that make the inequality v < 1  true are

{0 , -1 , -2,, -3, -4....}. An equivalent inequality, in terms of v, is v < 1.

In mathematics, an inequality is a relationship in which two numbers or other mathematical expressions compare unequal. Most commonly used to compare two numbers on the number line based on size. There are several notations used to represent various types of inequalities.

In both cases a is not equal to b. These relationships are known as strict inequalities. This means that a is either strictly less than or strictly greater than b. Equivalents are excluded.

There are two types of inequality relations that are not strict, as opposed to strict inequalities.

The notation a ≤ b or a ⩽ b means that a is less than or equal to b (or equivalently greater than max b or b).

The notation a ≥ b or a ⩾ b means that a is greater than or equal to b (or equivalently at least greater than or equal to b or b). The not-greater-than-relation can also be represented by the "greater than" symbol a ≯ b, split in two by a forward slash "not". The same is true if it is not less than a ≮ b.

The notation a ≠ b means that a is not equal to b. This inequality is sometimes considered a strict inequality .

To get the values that make the inequality true, we have to solve the inequality for . This will also give an equivalent inequality in terms of v < 1.

     \(\frac{v}{1} > \frac{1}{1}\)

⇒ v >-1

the solution set is the set of values {0, 1 ,2,3,4,5...} . In other words,  v can take up values less or equal to -1  to make the inequality -v > -1  true

Step-by-step explanation:

The points of horizontal tangency are (sqrt(3)/2, 1/2) and (-sqrt(3)/2, 1/2), and the points of vertical tangency are (1,0) and (-1,0).

To find the points of horizontal and vertical tangency to the polar curve r = 1 - sin(θ), we need to first convert the polar equation to Cartesian coordinates. This can be done using the following equations:

x = r cos(θ)

y = r sin(θ)

Substituting r = 1 - sin(θ), we get:

x = (1 - sin(θ)) cos(θ)

y = (1 - sin(θ)) sin(θ)

Now, to find the points of horizontal tangency, we need to find where dy/dθ = 0 and d^2y/dθ^2 < 0. Differentiating y with respect to θ, we get:

dy/dθ = (1 - sin(θ)) cos(θ) - (1 - sin(θ))^2 cos(θ)

Setting this equal to 0, we get:

cos(θ) = (1 - sin(θ)) cos(θ)

Simplifying, we get:

sin(θ) = 1/2

This gives us two values of θ: π/6 and 5π/6. Substituting these values into our Cartesian equations, we get the corresponding points of horizontal tangency:

(x,y) = (sqrt(3)/2, 1/2) and (-sqrt(3)/2, 1/2)

To find the points of vertical tangency, we need to find where dx/dθ = 0 and d^2x/dθ^2 > 0. Differentiating x with respect to θ, we get:

dx/dθ = (1 - sin(θ))^2 sin(θ) - (1 - sin(θ)) sin(θ)

Setting this equal to 0, we get:

sin(θ) = 0 or sin(θ) = 1/2

The first equation gives us θ = 0 or π, which correspond to the x-axis. Substituting these values into our Cartesian equations, we get:

(x,y) = (1,0) and (-1,0)

The second equation gives us θ = π/6 and 5π/6, which we have already used to find the points of horizontal tangency.

Therefore, the points of horizontal tangency are (sqrt(3)/2, 1/2) and (-sqrt(3)/2, 1/2), and the points of vertical tangency are (1,0) and (-1,0).

The probability that the sample mean would be greater than 148.6 millimeters is 0.017

The spread of all the data points in a data collection is taken into account by the variance, which is a measure of dispersion.

Given  Population mean μ= 147

Population Variance σ^2 = 25

So, population SD = 5

Size of sample = n = 44 Sample mean = x

To find P( y > 148.6) :

SE =σ/√n =

5/√44= 0.7538

Transforming to Standard Normal Variate:

Z = (x - μ )/SE    

= (148.6 - 147)/0.7538    

= 2.1226

From Table of Area Under Standard Normal Curve, corresponding to Z = 2.1226, area = 0.4830.

So, required probability = 0.5 - 0.4830 = 0.017

The probability that sample mean would be greater than 148.6 millimeters is 0.017

The P-value for the hypothesis test is approx. 0.7064.

To find the P-value for the hypothesis test, we need to perform a two-sample proportion test. The formula to calculate the test statistic for this test is given by:

\(\[ z = \frac{{(\hat{p}_1 - \hat{p}_2) - 0}}{{\sqrt{\hat{p}(1 - \hat{p})\left(\frac{1}{{n_1}} + \frac{1}{{n_2}}\right)}}} \]\)

where \(\hat{p}_1\) and \(\hat{p}_2\) are the sample proportions, \(\hat{p}\) is the combined sample proportion, \(n_1\) and \(n_2\) are the sample sizes, and 0 is the hypothesized difference in proportions.

In this case, we have \(n_1 = 50\), \(x_1 = 8\) (number of successes in sample 1), \(n_2 = 50\), and \(x_2 = 7\) (number of successes in sample 2).

First, we calculate the sample proportions:

\(\[ \hat{p}_1 = \frac{x_1}{n_1} = \frac{8}{50} = 0.16 \]\)

\(\[ \hat{p}_2 = \frac{x_2}{n_2} = \frac{7}{50} = 0.14 \]\)

Next, we calculate the combined sample proportion:

\(\[ \hat{p} = \frac{x_1 + x_2}{n_1 + n_2} = \frac{8 + 7}{50 + 50} = 0.15 \]\)

Then, we calculate the standard error:

\(\[ SE = \sqrt{\hat{p}(1 - \hat{p})\left(\frac{1}{{n_1}} + \frac{1}{{n_2}}\right)} = \sqrt{0.15(1 - 0.15)\left(\frac{1}{50} + \frac{1}{50}\right)} \approx 0.0529 \]\)

Finally, we calculate the test statistic:

\(\[ z = \frac{(\hat{p}_1 - \hat{p}_2) - 0}{SE} = \frac{(0.16 - 0.14) - 0}{0.0529} \approx 0.3772 \]\)

To find the P-value, we look up the test statistic in the standard normal distribution table. In this case, the P-value is the probability of observing a test statistic greater than 0.3772 or less than -0.3772.

Consulting the table, we find that the P-value is approximately 0.7064. Therefore, the P-value for the hypothesis test is approximately 0.7064.

The acceleration due to gravity (g) is given as 10 m/s², we can substitute the values and calculate the pressure on the base.

The weight of the water in the tank is 20 kg. We can calculate the force exerted by the water on the base by multiplying the weight by the acceleration due to gravity: force = weight × g. Substituting the given value of g (10 m/s²), we get force = 20 kg × 10 m/s² = 200 N.

To find the pressure, we divide the force by the area of the base: pressure = force / area. Substituting the values, we get pressure = 200 N / 0.25 m² = 800 N/m².

Therefore, the pressure on the base of the water tank is 800 N/m².
