A party rental company has chairs and tables for rent. The total cost to rent 8 chairs and 4 tables is $37. The total cost to rent 3 chairs and 2 tables is $17.
What is the cost to rent each chair and each table?
Cost to rent each chair: SI
Cost to rent each table:
Answers
Solving a system of equations we can see that the costs are:
For a chair, 3/2 dollars.
For a table, 25/4 dollars.
What is the cost to rent each chair and each table?Here we can define the variables:
x = cost of rending a chair.
y = cost of renting a table.
Here we can write a system of equations:
8x + 4y = 37
3x + 2y = 17
We can subtract two times the second equation from the first one:
8x + 4y - 2*(3x + 2y) = 37 - 2*17
2x = 3
x = 3/2
And the value of y is:
3*(3/2) + 2*y = 17
2y = 17 - 9/2 = 25/2
y = 25/2/2
y = 25/4
These are the costs in dolllars.

Start with the equation 0.2=0 to explain why -4-2 must equal -8.
Drag descriptions and equations to the table to complete the explanation.
Answers
In order to explain why -4 - 2 equals -8, let's start with the equation 0.2 = 0. By analyzing this equation, we can uncover the reason behind this seemingly counterintuitive result.
1. Begin with the equation 0.2 = 0.
2. Subtract 0.2 from both sides of the equation to isolate the variable: 0.2 - 0.2 = 0 - 0.2.
This simplifies to 0 = -0.2.
3. Observe that the right side of the equation, -0.2, is a negative number.
4. Recall that subtracting a negative number is equivalent to adding its positive counterpart. Therefore, -0.2 is the same as +0.2.
5. Rewrite the equation as 0 = +0.2.
6. Notice that 0 on the left side of the equation is equal to 0 + 0, since any number added to zero remains unchanged.
7. Substitute 0 + 0 for 0 in the equation: 0 + 0 = +0.2.
8. Simplify the equation to 0 = +0.2.
9. Finally, recognize that a positive number cannot equal zero. Hence, the equation 0 = +0.2 is false.
10. As a result, the original equation 0.2 = 0 is invalid.
11. Therefore, the logical consequence is that any subsequent deductions based on this invalid equation would also be incorrect.
12. Consequently, -4 - 2 does not equal -8, as per the explanation derived from the flawed equation.
To summarize, by analyzing the equation 0.2 = 0, we can determine that subsequent deductions based on this equation are incorrect. Hence, -4 - 2 does not equal -8.

Answers
Answer:
By comparing all the expressions with the formula (a - b)(a + b) = (a² - b²), we find that c, d and e options are correct.
Step-by-step explanation:
Concept: The condition is that, the product should result in a difference of squares. In mathematics, we have such a formula which is (a - b)(a + b) = (a² - b²). So, we need to compare all the options with this relation.
(x - y)(y - x) = -(x² - 2xy + y²)
(6 - y)(6 - y) = 36 - 12y + y²
(3 + xz)(-3 + xz) = (xz + 3)(xz - 3) = x²z² - 9 . This expression is correct
(y² - xy)(y² + xy) = \(y^{4} - x^{2} y^{2}\). This expression is correct
(64y² + x²)(-x² + 64y²) = (64y² + x²)(64y² - x²) = \(4096y^{4} -x^{4}\). This expression is correct.

2,5). Write its equation in slope-intercept form.
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answers
Answer:
y = x + 7
Step-by-step explanation:
The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. We are given that the slope of the line is 1, so we can substitute m = 1 into the equation:
y = 1x + bWe also know that the line passes through the point (-2, 5), so we can substitute x = -2 and y = 5 into the equation and solve for b:
5 = 1(-2) + b5 = -2 + bb = 7Therefore, the equation of the line in slope-intercept form is:
y = x + 7
This is the final answer, written in slope-intercept form using integers.Answer:
The Equation of the Line is : y = x + 7
Step-by-step explanation:
Equation of the Line in Slope-Intercept Form is y = mx + b
where m is the Slope and b is the y-intercept
since the slope (m) = 1 , Substitute by m = 1 in the above equation
Then the Equation will be y = x + b
Since the line passes through point ( -2 , 5 ) , Then y = 5 when x = - 2
Substitute , Then 5 = -2 + b

what is probability ?It is a scale among 0 and 1 that represents the probability or likelihood of an event happening. In many disciplines, including statistics, physics, economics, law, and computer science, probability theory is extensively used. Many situations, such as games of chance, weather predictions, medical diagnoses, and more, can be explained using the concept of probability. The mathematical computation of probabilities, the analysis for random variables, and the conclusion-making process are all included in the study of probability.
given
The likelihood that 162 or more kids in a randomly chosen sample of 340 pupils will have received a referral in that particular year can be calculated using the normal distribution.
Calculating the sample proportion is necessary:
The predicted value of p is equal to the 0.34 underlying proportion of referred pupils. It is possible to compute the sample proportion's standard deviation as follows:
P equals sqrt[p(1-p)/n] = sqrt[0.34(1-0.34)/340] = 0.031
Calculate the z-score to determine the likelihood of locating 162 or more kids with referrals:
\(z = (0.476 - 0.34) / 0.031 = 4.39\)
The likelihood of discovering a z-score of 4.39 or higher with a regular normal distribution table or calculator is extremely low, roughly 0.00001.

Order of the side lengths EF, FG, and GE from least to greatest is EF < FG < GE.
Give a brief account on Law of Coslnes?When the lengths of two sides and the size of the included angle are known (SAS) or when the lengths of all three sides are known (SSS), the Law of Cosines can be used to determine the remaining components of an oblique (non-right) triangle. We are unable to establish a solvable percentage in either of these scenarios, making it impossible to apply the Law of Sines.
According to the Law of Cosines:
c² = a² + b² - 2ab * cos(C)
With the exception of the third component, which equals zero if C is a straight angle and the Pythagorean Theorem results, this is similar to the Pythagorean Theorem. As a result, the Law of Cosines is a specific case of the Pythagorean Theorem.
Using the Law of Cosines
In the given triangle, we are given the measure of angle G and the length of side FG, so we can use the Law of Cosines to find the lengths of the other sides. The Law of Cosines states that for a triangle with sides a, b, and c and angle C opposite side c, the relationship between the sides and the angle is:
c² = a² + b² - 2ab * cos(C)
Given: angle G = 72°, FG = 6
We can use the Law of Cosines to find the lengths of the other sides:
EF² = FG² + GE² - 2FG * GE * cos(G)
EF = √(6² + GE² - 2 * 6 * GE * cos(72))
FG² = EF² + GE² - 2EF * GE * cos(F)
FG = √(EF² + GE² - 2 * EF * GE * cos(66))
As we don't have any value for GE, we can't calculate the exact values, but as we know that the side opposite to the largest angle is the longest side of a triangle, so we can order the sides as follows:
EF < FG < GE
It means that side GE is the longest side of the triangle, followed by side FG, and side EF is the shortest side of the triangle.

Suppose you are flying a kite at the park on a windy day. You notice that the height of the kite, h, is
affected by the speed of the wind, w. You decide to measure the height of the kite at different wind
speeds to determine the relationship between the two variables. After some experimentation, you
measure the height of the kite at three different wind speeds: 10 mph, 15 mph, and 20 mph. You
measure the height of the kite to be 50 feet at 10 mph, 75 feet at 15 mph, and 100 feet at 20 mph.
Determine the equations that relate the height of the kite to the speed of the wind.
Answers
The equation that relates the height of the kite to the speed of the wind is: h = 5w.
What is slope?
In mathematics, slope refers to the steepness or incline of a line on a graph. It is a measure of how much the dependent variable changes for every unit change in the independent variable.
To determine the relationship between the height of the kite and the speed of the wind, we can use linear regression to fit a line to the data points we have measured. The line will take the form y = mx + b, where y is the height of the kite, x is the speed of the wind, m is the slope of the line, and b is the y-intercept.
Using the three data points we have, we can calculate the slope of the line as follows:
m = (y2 - y1) / (x2 - x1)
= (75 - 50) / (15 - 10)
= 25/5
= 5
Therefore, the equation for the line is y = 5x + b. To find the value of b, we can use one of the data points.
For example, using the point (10, 50):
50 = 5(10) + b
b = 0
So the equation that relates the height of the kite to the speed of the wind is:
h = 5w
where h is the height of the kite in feet, and w is the speed of the wind in mph.

Step-by-step explanation:
Null hypothesis: the average age of a groom is now 26.2 years.
Alternative hypothesis: the average age of a groom is not 26.2 years.
We have a sample of 16 so we will use a t-test
Where t score = (x-u)/(sd/√n)
Where x = 26.6, u=26.2, sd= 5.3 and n=16
t score = (26.6-26.2) / (5.3/√16)
t = 0.4/(5.3/4)
t = 0.4/1.325
