Answers

Answer 1

Step-by-step explanation:

xy=6

x=6/y (1)

now,

XY=6

6/y-y=6

Answer 2
Answer:

x = -3, then y = -2
x = 2, then y = 3 both correct

Step by step explanation:

We can solve this system of equations algebraically by using substitution.

From the second equation, we can solve for y in terms of x:

y - x = 1

y = x + 1

Substituting y = x + 1 into the first equation, we get:

xy = 6

x(x + 1) = 6

Expanding the left side of the equation, we get:

x^2 + x = 6

Subtracting 6 from both sides, we get:

x^2 + x - 6 = 0

Factorizing the left side of the equation, we get:

(x + 3)(x - 2) = 0

Therefore, either x + 3 = 0 or x - 2 = 0. Solving for x, we get:

x = -3 or x = 2

Substituting these values of x into y = x + 1, we get:

if x = -3, then y = -2
if x = 2, then y = 3

So the solutions to the system of equations are (x, y) = (-3, -2) and (2, 3).

What are the different angle of rectangle?

A rectangle in Euclidean geometry is a parallelogram with four small angles. It can also be defined as a fundamental rule hexagon or one with all angles equal.

A straight angle is another alternative for the parallelogram. Four vertices in a square are the same length. A quadrilateral with a rectangle-shaped cross-section has four 90° angle vertices and equal parallel sides.

€ As a result, it is also known as a "equirectangular rectangle" in some circles. A rectangle is sometimes referred to as a parallelogram, since its two sides have equal and parallel dimensions.

here's how to draw a rectangle with the vertices A(2,-2),B(2,3),C(5,3),D(5,-2):

A machine produces 225,000 insulating washers for electrical devices per day. The production manager claims that no more than 4,000 insulating washers are defective per day. In a random sample of 200 washers, there were 4 defectives. Determine whether the production manager's claim is likely to be true. Explain.

Answers

The production manager's claim that no more than 4,000 insulating washers are defective per day is likely to be true, based on the sample of 200 washers.

What is proportion?

Proportion refers to the relationship between two quantities or numbers, indicating how they are related to each other in size or amount.

According to question:

To determine whether the production manager's claim is likely to be true, we can use hypothesis testing. We can formulate the following hypotheses:

Null hypothesis (H0): The true proportion of defective insulating washers is equal to or less than 0.02 (4,000/225,000).

Alternative hypothesis (Ha): The true proportion of defective insulating washers is greater than 0.02.

We can use a significance level of 0.05, which means we are willing to accept a 5% chance of rejecting the null hypothesis when it is actually true.

To test these hypotheses, we need to calculate the test statistic and p-value. We can use the normal approximation to the binomial distribution, since the sample size (200) is large enough and the proportion of defective washers is relatively small (0.02).

The test statistic is calculated as:

z = (0.02 - 0.02) / √(0.02×(1-0.02)/200) = 0

The p-value is the probability of getting a test statistic as extreme or more extreme than the one observed, assuming the null hypothesis is true. Since we are testing the alternative hypothesis that the true proportion of defectives is greater than 0.02, we need to calculate the right-tailed p-value. We can use a standard normal distribution to calculate the p-value:

p-value = P(Z > z) = P(Z > 0) = 0.5

We are unable to reject the null hypothesis since the p-value is higher than the significance level of 0.05. This means we do not have sufficient evidence to conclude that the true proportion of defective insulating washers is greater than 0.02.

Therefore, the production manager's claim that no more than 4,000 insulating washers are defective per day is likely to be true, based on the sample of 200 washers.

Find the slope of the tangent line to the ellipse x^(2)/16 +y^(2)/4=1 at the point (x,y). slope =?
Are there any points where the slope is not defined? (Enter them as comma-separated ordered-pairs, e.g., (1,3), (-2,5). Enter none if there are no such points.) slope is undefined at ?

Answers

The slope of the tangent line at the point (x,y) is -x/(2y). The ellipse's slope is not defined at the coordinates (4, 0), (-4, 0).

What is slope of a tangent?

The rate of change of a curve at a certain position is represented by the slope of a tangent line to the curve at that location. In other words, it indicates whether the curve is steep or shallow at that particular location. Calculating the derivative of a function in calculus also requires estimating the slope of a tangent line, which is a crucial step. We may determine the slope of the tangent line and subsequently the derivative of the function at a location by determining the limit of the slope of a secant line as the two points on the line approach closer and closer together.

The equation of the ellipse is x²)/16 +y²/4=1.

We take the derivative of the equation with respect to xto find the slope:

x²/16 + y²/4 = 1

(x²/16)' + (y²/4)' = 1'

2x/16 + 2y/4 * dy/dx = 0

dy/dx = -x/(2y)

When the denominator of 2y equals 0, there are some locations where the slope is not specified. The ellipse's slope is not defined at the coordinates (4, 0), (-4, 0), and all locations on the x-axis between these two points when y = 0, which occurs.

Hence, the slope of the tangent line at the point (x,y) is -x/(2y). The ellipse's slope is not defined at the coordinates (4, 0), (-4, 0).

As a sales analyst for the shoe retailer Foot Locker, one of your responsibilities is measuring store productivity and then reporting your conclusion back to management. Foot Locker uses sales per square foot as a measure of store productivity. While preparing your report for the second quarter results (Q2), you are able to determine that annual sales for last year ran at a rate of $406 per square foot. Therefore, $406 per square foot will be your sales estimate for the population of all Foot Locker stores during Q2.


For your Q2 Sales Report, you decide to take a random sample of 64 stores. Using annual data from last year, you are able to determine that the standard deviation for sales per square foot for all 3,400 stores was $80. Therefore $80 per square foot will be your population standard deviation when compiling your Q2 report.



You anticipate that management would be comfortable with a probability of 0. 500 when offering your estimate of the sample mean. Using σ = $80 and n = 64 as before, what dollar interval would you have to present in order to obtain a probability of 0. 500?

Answers

The dollar interval that would give a probability of 0.500 is X ± $8.47.

To determine the dollar interval that would give a probability of 0.500, we need to calculate the confidence interval using the formula:

Confidence interval = X ± Zα/2 × σ/√n

where:

X = sample mean

Zα/2 = Z-score for the desired level of confidence (in this case, 0.500 corresponds to a Z-score of 1.96)

σ = population standard deviation

n = sample size

Substituting the given values, we have:

Confidence interval = X ± 1.96 × 80/√64

Confidence interval = X ± 19.6

Since we want a probability of 0.500, we need to find the z-scores that correspond to the middle 50% of the normal distribution. Using a standard normal table, we can find that the z-scores are approximately -0.6745 and +0.6745.

Therefore, the confidence interval that will give a probability of 0.500 is:

X ± 0.6745 × 80/√64

X ± 8.47

So, when presenting the Q2 Sales Report to management, we would have to provide a dollar interval of X ± $8.47 to obtain a probability of 0.500.

why can't we use mean when a data set has one or two values that are much higher than all of the others

Answers

The reason we can't use the mean when a data set has one or two values that are much higher than all of the others is that it skews the average, making it not representative of the rest of the data.

What is the mean?

The mean is a numerical measure of the central tendency of a data set. It is calculated by dividing the sum of all the values in a data set by the number of data points.

A data set is a collection of observations or measurements that are analyzed to obtain information. It can be represented graphically, in tabular form, or in any other format. The data set may be a sample or the entire population.

If a data set has one or two extremely high or low values, it can significantly impact the mean. These values are known as outliers. The outliers can cause the mean to be higher or lower than the actual middle value of the data.

Hence, in such cases, the median is a better choice for finding the central tendency of the data. The median is the middle value of the data set, and it is less affected by outliers than the mean. The mode, which is the value that occurs most frequently in the data set, is also a measure of central tendency that is less sensitive to outliers than the mean.

I don't really understand how to do reference angles. I only need the last one, -60 degrees, does anyone know how to figure out it's reference angle?

Answers

Answer: 60?

Step-by-step explanation:

The reference angle is the acute angle formed between the terminal side of an angle in standard position and the x-axis. To find the reference angle of an angle, you can follow these steps:

Determine the quadrant in which the angle terminates. For -60 degrees, this would be the fourth quadrant.

Determine the corresponding angle in the first quadrant by finding the angle formed between the terminal side and the x-axis. In the fourth quadrant, this angle is equal to 360 degrees minus the original angle. So for -60 degrees, the corresponding angle in the first quadrant is 360 - 60 = 300 degrees.

Subtract this angle from 360 degrees to find the reference angle. For -60 degrees, the reference angle is 360 - 300 = 60 degrees.

Therefore, the reference angle of -60 degrees is 60 degrees.

In given triangle, the value of t is 3.75 and the value of s is 10.4.

What are the 3 sides of a triangle?

In a right triangle, the hypotenuse is the longest side, a "opposite" side is the one across from a given angle, and a "adjacent" side is close to a given angle. We use unique terminology to describe the sides of right triangles.

t / 5 = 6 / 8 (using the smaller triangle)

s / 13 = 8 / 10 (using the larger triangle)

Simplifying these ratios, we get:

t / 5 = 3 / 4

s / 13 = 4 / 5

At a party to celebrate a successful school play, the drama club bought 999 large pizzas. Each pizza had sss slices. All together, there were 727272 slices of pizza for the club to share.
Write an equation to describe this situation.
How many slices does each pizza have?

Answers

Answer:

Step-by-step explanation:

Let's use the variable "s" to represent the number of slices in each pizza.

The drama club bought 999 large pizzas, and each pizza had s slices. So, the total number of pizza slices is given by the product of 999 and s, which can be written as:

999s = 727272

To solve for s, we can divide both sides of the equation by 999:

s = 727272/999

Using a calculator, we can simplify this fraction to:

s ≈ 728.73

Therefore, each pizza has approximately 728 slices. Note that this is an unusual number of slices for a pizza, so it's possible that the problem is not intended to be taken literally, but rather as a math puzzle or word problem.

15x - 2x = 217500 - 107000

13x = 110500

x = 110500/13 = 8500

y = (72500 - 5x)/2 = y = (72500 - 5x8500)/2 = 15000

Two cars are driving away from an intersection in perpendicular directions. The first cars velocity isms 7 meters per second and the second cars velocity is 3 meters per second. At a certain instant, the first car is 5 meters from the intersection and the second car is 12 meters from the intersection. What is the rate of change of the distance between the cars at that instant?

Answers

The rate of change of the distance between the cars at that instant is 5.46 meters/ second.

The first car's velocity = 7 meters per second

The second car's velocity = 3 meters per second.

Distance from the intersection of first car = 5m

Distance from the intersection of second car = 12m

The rate of change is used to numerically quantify the percentage change in value over a predetermined period of time. It is a measure of a variable's velocity.

Calculating the distance between both cars at the instant

= √(12² + 5²)

= √ 144 + 25

= √169

= 13

Calculating the rate of change of distance -

2d/dt

= d(x² + y²)/dt

= 2x dx/dt + 2ydy/dt

= 2×5×7 + 2×12×3

= 70 + 72

= 142

Therefore, total distance -

dd/dt

= 142/26

= 5.46

- Per the NEC® the number of receptacles required in a classroom is ____. The room
is 36 feet x 24 feet with a 3-foot wide door at the far end of one of the 36-foot long walls. Nobody
lives there!

Answers

The number of receptacles required in the classroom is 14.

What is the number of receptacles?

To determine the number of receptacles required in a classroom, we need to consider the electrical code requirements for the room size and layout.

According to the National Electrical Code (NEC), there should be at least one duplex receptacle for every 12 linear feet of wall space in a classroom.

In addition, there should be at least one receptacle within 6 feet of each doorway and at least one receptacle on each wall space that is 2 feet or more in width.

Using this information and the dimensions provided, we can calculate the required number of receptacles as follows:

Calculate the perimeter of the room:

Perimeter = 2(Length + Width) = 2(36 + 24) = 120 feet

Calculate the total linear feet of wall space:

Total wall space = Perimeter - Width of door = 120 - 3 = 117 feet

Determine the number of receptacles required:

Number of receptacles = Total wall space / 12 + Number of doorways + Number of wall spaces wider than 2 feet

Number of doorways = 1 (as stated in the question)

Number of wall spaces wider than 2 feet = 2 (the two 24-foot-long walls)

Number of receptacles = (117 / 12) + 1 + 2 = 11 + 1 + 2 = 14

Rami worked on a recycling project. For 5 days he collected 24 glass bottles eachcigarette. On the sixth day he collected 30 bottles. How many bottles did he collect in all

Answers

Rami collected 150 glass bottles in all over the 6 days of his recycling project.

Arithmetic operations are basic mathematical calculations that involve addition, subtraction, multiplication, and division.

Rami collected 24 glass bottles each day for 5 days, so the total number of bottles he collected during those 5 days is:

24 bottles/day × 5 days = 120 bottles

On the sixth day, Rami collected an additional 30 bottles.

To find out how many bottles Rami collected in total, we can add up the number of bottles he collected on each day:

Total bottles collected = 120 bottles + 30 bottles = 150 bottles

you have spent $2,500 on liquor for your bar. your bar sales have been $12,890. what is your cost of sales for liquor, expressed as a percentage?

Answers

The cost of sales for liquor, expressed as a percentage is 19.39%.

What is the cost of sales for liquor in percentage?

To compute for the cost of sales for liquor, expressed as a percentage given that you have spent $2,500 on liquor for your bar and your bar sales have been $12,890, you can use the formula:

Cost of sales = (Cost of Goods Sold / Total Sales) × 100

where, Cost of Goods Sold (COGS) = Beginning Inventory + Purchases - Ending Inventory (or the total cost of goods sold during the period)

Total Sales = Gross sales - Sales discounts - Sales returns and allowances

Let's compute for the COGS first:

COGS = Beginning Inventory + Purchases - Ending Inventory

= $0 + $2,500 - $0

= $2,500

Total Sales = Gross sales - Sales discounts - Sales returns and allowances

= $12,890 - $0 - $0

= $12,890

Cost of sales is obtained as follows:

Cost of sales = (Cost of Goods Sold / Total Sales) × 100

= ($2,500 / $12,890) × 100

= 19.39%.

Therefore, the cost of sales for liquor, expressed as a percentage is 19.39%.
