For the equation 75x+30y=1500,  x is (100 - 2y) / 5 and y is (100 - 5x) / 2.

An equation is a mathematical statement that uses symbols and numbers to express a relationship between two or more variables. It states that two expressions are equal to each other.

We can solve for x and y in the equation 75x + 30y = 1500 by using algebraic manipulation.

First, we can simplify the equation by dividing both sides by the greatest common factor of 75 and 30, which is 15:

(75x + 30y) / 15 = 1500 / 15

Simplifying the left side gives:

5x + 2y = 100

Next, we can isolate one of the variables. Let's isolate y by subtracting 5x from both sides:

5x + 2y - 5x = 100 - 5x

Simplifying the left side gives:

2y = 100 - 5x

by dividing both sides by 2:

y = (100 - 5x) / 2

This is the equation for y in terms of x. We can use this equation to solve for y given a value of x, or we can substitute it back into the original equation to solve for x in terms of y.

Let's solve for x in terms of y by isolating x in the equation 5x + 2y = 100:

5x = 100 - 2y

Dividing both sides by 5 gives:

x = (100 - 2y) / 5

This is the equation for x in terms of y. We can use this equation to solve for x given a value of y, or we can substitute it back into the original equation to solve for y in terms of x.

Step-by-step explanation:

By answering the above question, we may state that So, 5333/10000 of linear equationthe cookies in the cookie jar are oatmeal cookies with nuts.

In algebra, a linear equation is one that of the form y=mx+b. The slope is B, and the y-intercept is m. As y and x are variables, the previous sentence is frequently referred to as a "linear equation with two variables". Bivariate linear equations are linear equations with two variables. Linear equations may be found in many places, including 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. When an equation has the structure y=mx+b, where m denotes the slope and b the y-intercept, it is referred to as being linear. A mathematical equation is said to be linear if its solution has the form y=mx+b, where m stands for the slope and b for the y-intercept.

For the sake of a simple computation, let's say that the cookie jar contains 100 cookies.

The issue states that 4/5 of the cookies in the jar are oatmeal cookies. So,

80 oatmeal cookies are equal to 4/5 * 100.

Two thirds of the oatmeal cookies have nuts in them. So,

2/3 times 80 equals 53.33 oatmeal cookies with nuts (approx)

As a result, the percentage of cookies in the cookie jar that are made with oats and nuts is:

53.33/100 = 0.5333

This is expressed as a fraction:

0.5333 = 5333/10000

Mr. Hamstra can travel about 70 miles when his tank is 1/4 full.

The distance a car can go on a given quantity of gasoline is measured as gas mileage, also known as fuel efficiency. By dividing the distance driven by the amount of gasoline used, one may determine gas mileage. For instance, a car's gas mileage is 25 mpg (300/12 = 25) if it can go 300 miles on 12 gallons of petrol. Many variables, including traffic, speed, weather, road gradient, and vehicle maintenance, can have an impact on gas mileage.

Given that, Mr. Hamstra’s car holds 14 2/5 gallons of gas and averages 20 miles per gallon.

2 times the square root of 48 minus the square root of 3 simplified is 7√3.

what is square root?

The square root of a number is a value that, when multiplied by itself, gives the original number. In other words, it is the inverse operation of squaring a number. For example, the square root of 16 is 4 because 4 multiplied by itself (4 x 4) equals 16.

The symbol used to represent the square root is √. So, the square root of 16 is written as √16.

To simplify this expression, we can first simplify the square root of 48.

We know that 48 can be written as 16 x 3, and since 16 is a perfect square, we can simplify the square root of 48 as follows:

√48 = √(16 x 3) = √16 x √3 = 4√3

Now we can substitute this value into the expression:

2(4√3) - √3 = 8√3 - √3 = 7√3

Therefore, 2 times the square root of 48 minus the square root of 3 simplified is 7√3.

Answer:

In business and economics, cost, revenue, and profit are key concepts that relate to the financial aspects of a business.

Cost refers to the expenses incurred by a business in order to produce, sell or distribute its products or services. This includes direct costs, such as the cost of raw materials, labor and overhead expenses, as well as indirect costs, such as marketing and administrative expenses.

Revenue, on the other hand, refers to the income generated by a business through the sale of its products or services. Revenue can be calculated by multiplying the price of a product or service by the number of units sold.

Profit is the difference between revenue and cost, and is a measure of how much money a business earns after all of its expenses are paid. A business earns a profit when its revenue exceeds its total costs, including both fixed and variable costs.

Profit can be further broken down into gross profit and net profit. Gross profit is the difference between revenue and the direct cost of producing or delivering a product or service. Net profit, on the other hand, is the profit that remains after all expenses, including indirect costs, taxes and interest payments, have been deducted from revenue.

In summary, cost refers to the expenses incurred by a business, revenue refers to the income generated by the sale of products or services, and profit is the difference between revenue and cost, indicating how much money a business earns after all expenses are paid.

To solve the equation graphically, we need to first rearrange it into the form of y = f(x). So, let's simplify the given equation:

(x - 3)² - 2 = x + 1

Expanding the left side:

x² - 6x + 9 - 2 = x + 1

Simplifying:

Here's a graph of the function and the line:

Graph of y=x^2-7x+6 and y=x+1

Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles.

Given points as:

J (-5,-3)

K (1,5),

L (7,-3)

b. To determine the distance between points K and L, we can use the distance formula:

distance = √(x₂ – x₁)² + (y₂ – y₁)²

Substituting the coordinates of K and L, we get:

distance = √((7 - 1)² + (-3 - 5)²)

distance = √(36 + 64)

distance = √(100)

distance = 10

Therefore, the distance between points K and L is 10 units.

c. To determine if JKL is an equilateral triangle, we need to check if all three sides have the same length.

We can find the lengths of each side using the distance formula:

JK = √((1 - (-5))² + (5 - (-3))²) = √(6^2 + 8²) = 10

KL = 10 (as we found in part b)

LJ = √((-5 - 7)² + (-3 - (-3))²) = √((-12)²) = 12

The statistical significance does not necessarily imply practical significance. In this case, while the IQ score of 160 is statistically significant, it may not necessarily be practically

To assess whether any of the IQ scores are statistically significantly high or low, we need to calculate the z-score for each score. The formula for calculating the z-score is:

z = (x - μ) / σ

Where x is the IQ score, μ is the mean IQ score, and σ is the standard deviation of IQ scores.

First, we need to calculate the mean and standard deviation of the IQ scores:

Mean = (100 + 90 + 110 + 160 + 90 + 85 + 65 + 100 + 95 + 98) / 10 = 99.3

Standard deviation = √[((100-99.3)² + (90-99.3)² + (110-99.3)² + (160-99.3)² + (90-99.3)² + (85-99.3)² + (65-99.3)² + (100-99.3)² + (95-99.3)² + (98-99.3)²) / 10] = 39.77

Now we can calculate the z-score for each IQ score:

z1 = (100 - 99.3) / 39.77 = 0.018

z2 = (90 - 99.3) / 39.77 = -0.233

z3 = (110 - 99.3) / 39.77 = 0.27

z4 = (160 - 99.3) / 39.77 = 1.53

z5 = (90 - 99.3) / 39.77 = -0.23

z6 = (85 - 99.3) / 39.77 = -0.36

z7 = (65 - 99.3) / 39.77 = -0.86

z8 = (100 - 99.3) / 39.77 = 0.017

z9 = (95 - 99.3) / 39.77 = -0.108

z10 = (98 - 99.3) / 39.77 = 0.032

Using the z-table, we can find the percent of scores below each z-score:

z1 =  0.018 or 70.01%

z2 = -0.233 or 34.67%

z3 = 0.27 or 75.01%

z4 = 1.53 or 83.68%

z5 = -0.23 or 34.67%

z6 = -0.36 or 37.47%

z7 = -0.86 or 45.16%

z8 =  0.017 or 70.01%

z9 = -0.108 or 31.80%

z10 =  0.032 or 69.15%

To determine whether each z-score is statistically significant, we need to compare it to a predetermined level of significance, typically α = 0.05. If the probability associated with the z-score (i.e., the percent of scores below it) is less than or equal to α, we consider the score statistically significant.

Based on this criterion, the only score that is statistically significant is the IQ score of 160 (z-score = 2.29, percent of scores below = 83.68%). All other scores have a probability greater than α, and therefore are not statistically significant.
