1. Situation: There will be a centerpiece on each table. A centerpiece costs $5.50. Represent the relationship between the number of centerpieces and the total cost for the centerpieces. Table: Algebraic rule: Process Graph:
Answers
The proportional relationship between the number of centerpieces and the total cost for the centerpieces is graphed at the end of the answer.
Proportional relationships and graphsA graph represents a proportional relationship if the output variable y in the y-axis is written as a product of the input variable x in the x-axis and the constant of proportionality k, as follows:
y = kx.
The constant k is called the slope of the unit rate of the situation, measuring by how much y changes when x changes by 1.
In the context of this problem, the cost of each centerpiece is of $5.50, hence the constant is given as follows:
y = 5.5x.
The number of centerpieces cannot be negative, hence the domain of the relation is given as follows:
x ≥ 0.
Considering this domain, the graph of the relation is given at the end of the answer.

Simple Interest: What Is It?Simple interest can be said as a quick and simple formula for figuring out how much amount of interest will be charged on a loan. The daily interest rate, the principle, and the total number of days present between payments are multiplied to calculate the simple interest.
FormulationA = P (1 + rt)
FINAL AMOUNT = A
P is the starting primary balance.
Annual interest rate is r.
T = time (in years)
According to question,

Determine the interval(s) for which the function shown below is increasing.
Answers
Answer:
(-∞, -3) and (-1, ∞)
Step-by-step explanation:
A function is increasing when the gradient is positive.
A function is decreasing when the gradient is negative.
A function is stationary when the gradient is zero.
From inspection of the given graph, the turning points of the function are (-3, 3) and (-1, -1). Therefore, the gradient is zero at these points.
From inspection of the graph:
The function is increasing on the interval (-∞, -3).The function is stationary at x = -3.The function is decreasing on the interval (-3, -1).The function is stationary at x = -1.The function is increasing on the interval (-1, ∞).Therefore, the function is increasing on the intervals (-∞, -3) and (-1, ∞).

Dividing Decimals: Rounding the quotient, 0.03 divided by 0.148 =
Answers
The quotient when 0.03 is divided by 0.148 after rounding it off is 0.2.
According to the question,
We have the following information:
0.03 is divided by 0.148
And it can be simply expressed as 0.03/0.148
Now, we have the quotient as:
0.2027
Now, when rounding off the numbers we know that the digits from where we are rounding off we look at the right next to that digit and when that digit is greater than 5 then the digit should be increased by 1 and when that digit is less than 5 then the digit should be the same.
So, we will round it off by taking the underlined digit to be next to first 2:
So, the digit is 0.
Butt if we are taking the underlined digit as 2 to be the next 2 then the digit next to it is 7 which is greater than 5.
Then, we have:
0.2
Hence, the quotient when 0.03 is divided by 0.148 after rounding it off is 0.2.

Answers
The probability that none of the solar panels are defective is 0.97.
What is probability?The probability is the likelihood that something will happen, to put it simply. When we don't know how something will turn out, we can talk about the possibility of one outcome or the likelihood of several.The study of events that fit into a probability distribution is known as statistics.The foundation for the modern mathematical theory of probability was built by Gerolamo Cardano, Pierre de Fermat, and Blaise Pascal in their analysis of games of chance in the sixteenth and seventeenth centuries, respectively.So, the faulty solar panel percentage, p = 1/200 = 0.005.
q = 1 - p = 1 - 0.005 q = 0.995 is the percentage of solar panels that are in good condition.Sample size, n = 6 likelihood that there are no damaged solar panels:
P(X=0)P = 0.97So, the probability: 0.97
Therefore, the probability that none of the solar panels are defective is 0.97.

whats the gcf and distributive property of 15+36
Answers
The gcf of 15 and 36 is 3 and 15 + 36 by distributive property is 51.
What is gcf?
The gcf(greatest common factor) is the greatest factor that divides both numbers. To find the greatest common factor, first list the prime factors of each number. 18 and 24 share one 2 and one 3 in common. We multiply them to get the GCF, so 2 * 3 = 6 is the GCF of 18 and 24.
What is distributive property?
According to the distributive property, multiplying the sum of two or more addends by a number produces the same result as when each addend is multiplied individually by the number and the products are added together. A (B + C) = AB + AC.
Given that, 15 and 36
Factor of 15 = 3 × 5
Factor of 36 = 2 × 2 × 3 × 3
gcf of 15 and 35 is 3 because 3 only one 3 is common in both the number.
Applying distributive property on 15 an 35 = 15 + 36
= 3×5 + 3×12
= 3(5 + 12)
= 3(17) = 51
Therefore, the gcf of 15 and 36 is 3 and 15 + 36 by distributive property is 51.

a) As per the given percentage, the number of registered voters in the town who cast the votes are 155,952.
b) Reese claim is incorrect. The number he mentioned as registered voters is greater than the actual number of registered voters..
Percentage:
A percentage is a number or ratio which can be expressed as a fraction of 100.
For example, 57% can be written as 57/100.
Given,
The register voters and other in the town cast their vote on the election day.
a. In that particular town, 273,600 votes were cast in an election. And there are 57% of those who were registered voted.
Here we need to find how many registered voters are there in the town.
b. Reese claims that there are 60% of the registered voters cast 273,600 votes, there would be fewer registered voters than above.
Now we have also need to find whether his statement is correct or not with the reason.
Let x be the total number of registered voter who cast the vote.
From the given details, we know that, there are 273,600 voters are cast.
And 57% of them are registered voters.
So, it can be calculated as follows,
=> x = 273600 of 57%
=> x = 273600 x 57%
=> x = 273600 x 57/100
=> x = 2736 x 57
=> x = 155, 952
Therefore, there are 155,952 registered voter in the town who cast the vote.
Based on these calculation we know that, Reese claims is incorrect because there the number of registered voters is 155, 952 which is not equal to the number he mentioned.

Answers
When working with unknowable numbers, we can simplify equations by using the distributive property. If the equation be 10x² - (9x + 4x²) + 7 + (5x - 8) then we get 6x² - 4x - 1.
What is meant by distributive law?The distributive property of binary operations in mathematics generalizes the distributive law, which states that in elementary algebra, equality is always true.
Let the equation be 10x² - (9x + 4x²) + 7 + (5x - 8)
Apply rule: a +(b + c) = a + b + c
7 + (5x - 8) = 7 + 5x - 8
= 10 x²- (9 x + 4 x²) + 7 + 5x - 8
simplifying the above equation, we get
= -(9x + 4x²) + 10x² + 5x + 7 - 8
Subtract the numbers: 7 - 8 = -1
= -(9x + 4x²) + 10x² + 5x - 1
Apply the distributive law: -(a + b) = -a - b = 0
-(9x + 4x²) = - 9x - 4x²
= -9x - 4x² + 10x² + 5x - 1
Add similar elements:
-4x² + 10x² = 6x² = -9x + 6x² + 5x - 1
simplifying the above equation, we get
= 6x² - 9x + 5x - 1
Add similar elements: -9x + 5x = -4x
= 6x² - 4x - 1
Therefore, by simplifying the equation, we get 6x² - 4x - 1.

A car with an initial speed of 36 km/h accelerates at a uniform rate of 2.4 m/s^2 for 2.5 seconds. What are the final speed and displacement of the car during this time?
Answers
If a car with an initial speed of 36 km/h accelerates at a uniform rate of 2.4 m/s^2 for 2.5 seconds. The final speed is 16m/s and displacement of the car during this time is 32.5m.
Speed and displacement23.7 km/h = 10 m/s
Using this formula to find the speed vf = vi + a(Dt) for the final speed
Where:
Initial speed = 10 m/s
Acceleration = 2.4 m/s2
Time = 2.5 s
Let plug in the formula
vf = (10 m/s) + (2.4 m/s2)(2.5 s)
vf = 16m/s fast car
Now, let's find or determine the displacement
Using this formula Dx = vi(Dt) + 1/2a(Dt)2
Let plug in the formula
Dx = (10 m/s)(2.5 s) + 1/2(2.4 m/s2)(2.5 s)²
Dx = 32.5 m
Therefore we can conclude that the speed is 16m/s and the displacement is 32.5 m.
