An inequality is the representation of an algebraic statement with two non-equal values. One of the two variables can be larger than, more than or equal to, smaller than, or equal to another value by using a sign of inequality.

One of the following options is available for resolving an inequality: Add the same amount to each side, deduct the same amount from each side, multiply each side by the same positive number, or split each side in half. If you multiply or divide each side by a negative value, the inequality sign must be reversed.

Given,

(x-0)(x-6)<0

⇒ x < 0 and x < 6

On solving the provided question, we can say that the equation of inequality will be as follows 150x + 100y [tex]\leq[/tex] 300

An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

A patient is not allowed to have more than 300 milligrams of cholesterol per day from a diet of eggs and meat.

Only Euna successfully constructed an equilateral triangle inscribed in a a circle.

An equilateral triangle's sides are congruent, which indicates that they are all the same length. The inner angles are all equal (60°), as well. Equilateral is a compound word made up of the words "equi," which means equal, and "lateral," which means side. Thus, an equilateral triangle is one that has three sides of equal length. An equilateral triangle in geometry is a triangle whose three sides are equal in length. An equilateral triangle is also equiangular in the conventional Euclidean geometry, meaning that each of the three internal angles is 60 degrees and that all three are congruent with one another.

The coordinates of the vertices of the image include the following: (-1, 3), (-1, -1), (5, -1), and (7, 3).

In this exercise, we would have to dilate (enlarge) the coordinates of the pre-image by using a scale factor of 2 centered at the point (1, 5) by using this mathematical expression:

(x, y)  →  (k(x - a) + a, k(y - b) + b)

For coordinate 1, we have;

Coordinate 1 = (2, 4)  →  (2(2 - 1) + 1, 2(4 - 5) + 5)

Coordinate 1 = (2, 4)  →  (2(-1) + 1, 2(-1) + 5)

Coordinate 1' = (-1, 3).

For coordinate 2, we have;

Coordinate 2 = (2, 2)  →  (2(2 - 1) + 1, 2(2 - 5) + 5)

Coordinate 2 = (2, 2)  →  (2(-1) + 1, 2(-3) + 5)

Coordinate 2' = (-1, -1).

For coordinate 3, we have;

The formula cosec (A + B) = sinA cosB - cosA sinB ÷ (sinA + sinB)(sinA - sinB) can be proven using the trigonometric identities.

Starting with the definition of cosecant:

cosec (A + B) = 1/sin (A + B)

Using the sum-to-product identity:

sin (A + B) = sinA cosB + cosA sinB

Substituting this expression into the definition of cosecant:

cosec (A + B) = 1 / (sinA cosB + cosA sinB)

Using the difference-to-product identity:

sinA - sinB = 2sin((A - B)/2)cos((A + B)/2)

Dividing both numerator and denominator by 2sin((A - B)/2)cos((A + B)/2), we get:

cosec (A + B) = (sinA cosB - cosA sinB) ÷ (sinA + sinB)(sinA - sinB)

Therefore, the formula cosec (A + B) = sinA cosB - cosA sinB ÷ (sinA + sinB)(sinA - sinB) has been proven.

Firstly let's make a table;

[tex]\boxed{\begin{array}{c|c|c} x & 0 & 1 \\ y & 2 & 1.5 \end{array}}[/tex]

Now plot the points , (0,2) and (1,1.5) .

Similarly make another table for second equation [tex] y = -3x - 3[/tex] as ,

[tex]\boxed{\begin{array}{c|c|c} x & 0 & 1 \\ y & -3 & -6\end{array}}[/tex]

Now draw the lines joining the points. Hence from the graph the line intersects at (-2,3)

So the solution to equations are ,

[tex]\boxed{\begin{array}{c|c|c} x & 12 & 16 \\ y & 0 & 1\end{array}}[/tex]

make a table for plotting equation [tex] 7x-4y=12[/tex]

[tex]\boxed{\begin{array}{c|c|c} x & 0 & 2 \\ y & -3 & 0.5\end{array}}[/tex]

Now we see that the equations intersect at point (4,4) So the solution to the given equation is ,

________________________________

[tex] 3. \begin{cases} -8x-4y = 12 \dots (1)\\\\ x=y\dots(2)\end{cases}[/tex]

substitute value of equation 2 in 1

Side LM = Hypotenuse

With respect to ∠M:

Side LN = Opposite side

Side MN = Adjacent side

Trigonometric function applied:

sin∠M = [tex]\frac{opposite}{hypotenuse}[/tex]

           = [tex]\frac{8}{22}[/tex]

 ∠M = [tex]sin^{-1} (\frac{8}{22})[/tex]

Before solving for fractions, you must know what you're doing. This will list information you should know to solve fraction problems.

A fraction represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters

[tex]\frac{5}{12} + \frac{1}{4}[/tex] is our equation, so let's solve this step by step,

Common Denominator

As you can see, the fractions have unlike denominators. An unlike denominator is when 2 or more fractions have different denominators. One of our denominators is 12 and the other is 4, so this shows we have unlike denominators. The way we get the denominators to be the same is multiplying. Its a quicker method to easily make them the same. We can also skip count until the numbers meet:

12: 12,

4: 4, 8, 12

The fraction denominator can be 12. We can also prove that it is 12 by showing the Least Common Denominator, or LCD. LCD (5/12, 1/4) = 12.

[tex]\frac{5}{12}[/tex] × [tex]\frac{1}{1}[/tex] = [tex]\frac{5}{12}[/tex] . We multiply this by [tex]\frac{1}{1}[/tex] because the denominator is already 12.

[tex]\frac{1}{4}[/tex] × [tex]\frac{3}{3}[/tex] = [tex]\frac{3}{12}[/tex].  We multiply this by [tex]\frac{3}{3}[/tex]  so we can make the denominator 12.

Adding the fractions

Now that we have our equation, [tex]\frac{5}{12}[/tex]  + [tex]\frac{3}{12}[/tex], we can easily add the fractions.

We do not add the denominators, however, we do add the numerators. We can express this as [tex]\frac{5+3}{12}[/tex]. 5 + 3 = 8. So, the numerator is 8. This means our answer is [tex]\frac{8}{12}[/tex].

Reduce

As your question says the sum must be in simplest form, you must reduce the answer to get it in simplest form. To reduce, you must divide. [tex]\frac{8}{12}[/tex] can be reduced, or divided by 4 to get it to simplest form. [tex]\frac{8}{12}[/tex] ÷ [tex]\frac{4}{4}[/tex] = [tex]\frac{2}{3}[/tex].

which is 69

after that find the median between the arranged numbers starting from 5 to the median which we found as 69

The level of scale of measurements is the ratio scale for the data of the average weight of newborn babies in ounces.

A ratio scale is a numerical scale with a genuine zero and uniform distances between adjacent points. A zero on a ratio scale, in contrast to an interval scale, indicates complete lack of the variable being measured. Examples of ratio scales include length, area, and population.

As, There are four scales of measurement: Nominal, Ordinal, Interval, and Ratio.

First, The categories in this scale are given names, hence the label "nominal." There is no innate hierarchy among the categories. Simply said, it is impossible to say that one category is superior to or better than another.

Ordinal scale: It is possible to rationally organise the various categories in a meaningful order. The distinction between the categories is not "meaningful," nevertheless.

Interval scale: Doubling has no significance, but values (not categories) can be arranged and have substantial differences. The lack of a "absolute zero" is the reason of this.

Scale of ratios: The values can be arranged in a way that makes a meaningful difference, and doubling also makes a difference. "Absolute zero" exists.

As a result, the ratio scale for the level of measurements is used to determine the average weight of newborn babies.

To maximize the store's profit, Hector should aim to sell as many lemons as possible while paying the lowest price possible for them. Since Hector estimates that he can sell a maximum of -2000p + 7540 lemons at price p, and Walt can supply at most 5000 lemons, Hector should buy all of the 5000 lemons from Walt.

To determine the price at which Hector should buy the lemons from Walt, we need to consider the average cost of the lemons. If Hector buys 5000 lemons at $1.60 per lemon, he will spend a total of 5000 x $1.60 = $8000 on lemons.

If he sells all 5000 lemons at the price p, his revenue will be (-2000p + 7540) x 5000 = -10,000,000p + 37,700,000.

His profit will be the difference between revenue and cost, which is given by:

Profit = -10,000,000p + 37,700,000 - $8000

To maximize profit, we need to take the derivative of the profit function with respect to p and set it equal to zero:

dProfit/dp = -10,000,000 = 0

Solving for p, we get:

p = $1.00

Therefore, Hector should buy 5000 lemons from Walt at $1.00 per lemon to maximize the store's profit.

For the given scenario the mean changes from 80.42 to 82.

In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.

Given that, the average high temperatures in degrees for a city are 58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57.

Now, average = (58+61+71+77+91+100+105+102+95+82+66+57)/12

= 965/12

= 80.42

If a value of 101° is added to the data, then the new average is
