In Mathematics, the relationship between two values which are not equal is expressed by inequalities. The equation of inequality for the given graph is y ≥ -1/2x + 2.  

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 different notations used to represent different types of inequalities.

In both the cases a is not equal to b and such relationships are known as strict inequalities. This means that a is either strictly less than or greater than b. Equivalents are excluded whereas in inexact inequalities.

For the given graph:

take run = 1 and rise = -1/2

Thus, the slope will be,

Slope = (⁻¹/₂)/1

Slope = -1/2

Since, the y intercept is 2. Then the equation is y = -1/2x + 2

Take point (1,2) on the graph and apply in the equation:

y = -1/2x + 2

2 = -1/2 (1) + 2

2 = -1/2 + 2

2 = 3/2

As, 2 > 3/2. We can replace the = sign into ≥.

So, the eq inequality equation is y ≥ -1/2x + 2.

Answer:

x = y = 2√7 = 5.292

Step-by-step explanation:

We have a right isosceles triangle, so the length of the hypotenuse is √2 times the length of each leg. Since the hypotenuse is 2√14, each leg measures 2√7.

The length of the sides of the right isosceles triangle is 5.292units.

A right isosceles triangle is a special type of triangle that has two equal-length legs and a right angle between them. Because it has two equal legs, it is also an isosceles triangle. The name "right isosceles" comes from the fact that it has a right angle and two equal legs.

In the given question,

In a right isosceles triangle, the two legs are congruent, and the length of the hypotenuse can be found using the Pythagorean theorem:

a² + b² = c²

Since this is an isosceles triangle, we know that a = b, so we can simplify the equation to:

2a² = c²

Taking the square root of both sides, we get:

a√2 = c

In this case, we are given that the hypotenuse has a length of 2√14, so we can set c equal to that value and solve for a:

a√2 = 2√14

a = (2√14)/√2

Simplifying the expression by canceling the square root of 2 in the denominator, we get:

a = 2√7

Therefore, each leg of the isosceles triangle has a length of 2√7, which agrees with your answer.

The probability that exactly one of three randomly selected high school students graduate, given an 85% graduation rate, is 0.057. This calculation was based on the combination formula and the binomial probability distribution.

This problem involves calculating the probability of a specific outcome (exactly one of the three students graduating) in a binomial distribution. We know that the probability of any one student graduating is 0.85, so the probability of one student not graduating is 0.15. Using the binomial probability formula, we can calculate the probability of exactly one student graduating out of three as:

P(X = 1) = (3 choose 1) * (0.85)^1 * (0.15)^2 = 3 * 0.85 * 0.0225 = 0.057

Therefore, the answer is 0.057, or approximately 5.7%. This means that if we randomly select three high school students from different schools, there is a 5.7% chance that exactly one of them will graduate.

A trapezoid is a quadrilateral with at least one pair of parallel sides. In this case, we are given that AB is parallel to CD. The base angles theorem states that the base angles of an isosceles trapezoid are congruent. Since AB and CD are congruent (as given by the reflective property of congruence), the opposite angles formed by the intersecting lines BA and CD (i.e., ∠BAD and ∠CDA) are congruent as well. This establishes that ABCD is an isosceles trapezoid. An isosceles trapezoid has two pairs of congruent sides: AB = CD and AC = BD. Since BA and CO are congruent (as given), we can conclude that AC and BD are congruent as well (by the isosceles trapezoid definition).

The arch has a width of 6 - (-6) = 12 feet at ground level.

To find the width of the arch at ground level, we need to find the x-values where y = 0, since the width of the arch is the distance between these two x-values.

So, we set y = 0 and solve for x:

0 = − 1/3(x + 6)(x − 6)

Either x + 6 = 0 or x - 6 = 0

If x + 6 = 0, then x = -6.

If x - 6 = 0, then x = 6.

To find the width of the arch at ground level, we need to find the x-values where y=0.

y = − 1/3(x + 6)(x − 6)

Setting y=0:

0 = − 1/3(x + 6)(x − 6)

We can solve for x using the zero product property:

0 = x + 6 or 0 = x - 6

x = -6 or x = 6

The length of the side AC or the height of the smaller equilateral triangle is 3√2 inches.

The length of the side AC is equal to the height of the smaller equilateral triangle.

We know that in an equilateral triangle, all sides are equal, and all angles are 60 degrees.

Let's call the height of the smaller equilateral triangle h, and the length of one side of the smaller triangle x.

We can use the Pythagorean theorem to find the value of h:

(1/2)x^2 + h^2 = x^2

h^2 = x^2 - (1/2)x^2

h^2 = (1/2)x^2

h = sqrt((1/2)x^2)

Now, we also know that the side of the large equilateral triangle is 6 inches, so x = 6 inches.

Substituting this value into the equation for h, we get:

h = √((1/2)(6^2))

h = √(18)

h = 3√2 inches.

Therefore, the height of the smaller equilateral triangle is 3√2 inches.

The total health care expenditures in year x would be equal to the product of the percentage of income spent on health care (P(x)) and the income (I(x)) in year x. Therefore, the function H can be expressed as:

H(x) = P(x) * I(x)

This function takes into account both the amount spent on health care as well as the income level, providing a comprehensive representation of health care expenditures.

Step-by-step explanation:

that depends on the result dimension of P(x).

if P(x) delivers the percentage in the form xx.xx%, then

H(x) = I(x) × P(x) / 100

if P(x) delivers the percentage in the form 0.xxxx, then

H(x) = I(x) × P(x)

very basically, the absolute amount of a percentage of a whole is the product between both (and divided by 100).

e.g.

let's say, the whole amount is $64,000.

and we need to know 10% of that.

10% of 64,000 is then

Answer: 10

If a teacher cuts out 15 congruent circles from a single sheet of paper that measures 6 inches by 10 inches, then (60 - 1.5 π) square inches paper is wasted.

The area of each circle is given by the formula [tex]A = \pi r^2[/tex], where r is the radius of the circle. Since all 15 circles are congruent, they all have the same radius.

Let's first find the radius of each circle. Since the circles are cut from a 6 by 10 inch sheet of paper, we know that the diameter of each circle cannot be greater than 6 inches or 10 inches. Let's take the smaller dimension (6 inches) and divide it by 15 to find the maximum possible diameter of each circle:

6 inches ÷ 15 = 0.4 inches

Therefore, the maximum possible radius of each circle is 0.2 inches.

Now we can calculate the total area of all 15 circles:

Total area of circles = [tex]15 * \pi * (0.2)^2[/tex]

[tex]= 1.5 \pi[/tex] square inches

The area of the original sheet of paper is 6 inches * 10 inches = 60 square inches. Therefore, the amount of paper wasted is:

Amount of paper wasted = Area of sheet - Total area of circles

= 60 square inches - 1.5 π square inches

= 60 square inches - 4.71 square inches (using π ≈ 3.14)

= 55.29 square inches (rounded to two decimal places)

Therefore, the answer is (60 - 1.5π) square inches.

Step-by-step explanation:

The test statistic is z = 0.68, and the p-value is approximately 0.2486.

This problem involves testing the hypothesis that the proportion of union workers in the population has increased from 11.5%.

Let p be the true proportion of union workers in the population.

The null hypothesis is H0: p = 0.115, and the alternative hypothesis is Ha: p > 0.115 (one-tailed test, since we are testing for an increase in union membership).

To find the test statistic, we use the formula for a z-test for proportions:

z = ([tex]\bar p[/tex] - p) / [tex]\sqrt{(p(1-p)/n) }[/tex]

where, [tex]\bar p[/tex] is the sample proportion, n is the sample size, and sqrt denotes the square root function.

In this case, [tex]\bar p[/tex] = 36/300 = 0.12, n = 300, and p = 0.115.

Substituting these values into the formula, we get:

z = (0.12 - 0.115) / [tex]\sqrt{(0.115(1-0.115)/300) }[/tex]≈ 0.68

To find the p-value, we need to find the probability of getting a test statistic as extreme or more extreme than 0.68, assuming that the null hypothesis is true (i.e., assuming that p = 0.115).

Since this is a one-tailed test, we need to find the area under the standard normal curve to the right of 0.68:

p-value = P(Z > 0.68) ≈ 0.2486

Using a standard normal distribution table or a calculator, we find that the area to the right of 0.68 is approximately 0.2486.

Therefore, the p-value for the test is approximately 0.2486.
