What are the 3 defining characteristics of parallel lines?.
Answers
The characteristics of parallel lines:
1) Parallel lines lie in the same plane
2) The parallel lines never intersect each other.
3) The slopes of parallel lines are equal.
We know that two lines are parallel to each other if they lie in the same plane and never intersect each other.
Parallel lines are always equidistant from each other.
Also, the parallel lines are coplanar.
Mathematically, the parallel lines are represented by the symbol, ‘||‘.
If two lines l₁ and l₂ are parallel to each other then they are represented as l₁ || l₂.
Also, the slopes of parallel lines are equal.
Let m₁ be the slope of line l₁ and m₂ be the slope of line l₂.
If line l₁ and l₂ are parallel to each other then m₁ = m₂

wave interference that results in greater wave amplitude is called_____.
Answers
Wave interference that results in greater wave amplitude is called Constructive interference.
What is Wave Interference?
Wave interference is a physical phenomena that occurs when two waves collide while traveling through the same medium. Waves interact in two ways.
a) Constructive Interference - In this case, the two waves cancel each other out because their amplitudes are equal and opposite.
b) Destructive Interference - This occurs when two waves add to each other as they travel in the same direction, resulting in a wave with a longer wavelength.
It is Constructive interference.
Therefore, Wave interference that results in greater wave amplitude is called Constructive interference.

If Savannah travels 35 miles from home, is it possible she is at work? Be prepared to share your reasoning.
Answers
The distance of 35 miles alone does not provide enough context to ascertain her location or activity.
The possibility of Savannah being at work depends on several factors such as the proximity of her workplace to her home, the mode of transportation she uses, and her work schedule. If her workplace is within 35 miles of her home, it is plausible that she could be at work. However, if her workplace is farther away or if she is engaged in other activities, such as running errands or visiting friends, she may not be at work despite being 35 miles from home.

This table shows the ticket price for each person to visit a zoo in winter.
adult = £18
child (3-17) = £14
child ( under 3) = free
A family of two adults, one child aged 8 and one child aged 1 visit the zoo in winter.
In summer, the zoo increases the prices.
An Adult ticket increases by 20%.
A Child ticket increases by 15%.
How much more does it cost the family to visit in the summer than in the winter?
Answers
Answer: £9.3 more
Step-by-step explanation:
Price for winter tickets: £18 + £18 + £14 = £50
Summer tickets pricing:
£18 + 20% = £21.6
£14 + 15% = £16.1
Price for summer tickets: £21.6 + £21.6 + £16.1 = £59.3
Subtract winter tickets from summer tickets for difference:
£59.3 - £50 = £9.3

Answer:
Perimeter = (4x + 12)
Step-by-step explanation:
As given in the question itself,
"Perimeter of a polygon is the sum of measures of all the sides of the polygon."
By this property expression to calculate the perimeter of the given polygon will be,
Perimeter = x + x + x + 2 + 2 + (x + 4) + 2 + 2

Answers
Answer: i) Both A and R are true and R is the correct explanation of the assertion
Step-by-step explanation:
When Calcium Oxide (Quick lime) reacts with water, it is a very rigorous reaction that produces a lot of heat and may even boil the water or burn the skin if it comes into contact with it. The resulting compound is Calcium Hydroxide. The Assertion is therefore true.
A Combination reaction does indeed result in only a single product being created or formed after a reaction. The above reaction is indeed a Combination reaction due to the production of only one Compound being Calcium Hydroxide.

the expected value is equal in mathematical computation to the ____________
Answers
The expected value is the long-term average outcome of a random variable. It is calculated by multiplying each possible outcome by its probability and summing them up. In simpler terms, it represents the average value we expect to get over many trials.
The expected value is a concept in probability and statistics that represents the long-term average outcome of a random variable. It is also known as the mean or average. To calculate the expected value, we multiply each possible outcome by its probability and sum them up.
For example, let's say we have a fair six-sided die. The possible outcomes are numbers 1 to 6, each with a probability of 1/6. To find the expected value, we multiply each outcome by its probability:
1 * 1/6 = 1/62 * 1/6 = 2/63 * 1/6 = 3/64 * 1/6 = 4/65 * 1/6 = 5/66 * 1/6 = 6/6Summing up these values gives us:
1/6 + 2/6 + 3/6 + 4/6 + 5/6 + 6/6 = 21/6 = 3.5
Therefore, the expected value of rolling a fair six-sided die is 3.5. This means that if we roll the die many times, the average outcome will be close to 3.5.

Assume that you are pouring a wall that is 151 feet - 4 inches long, 14 feet high and 16 inches thick and the daily placement rate is 375 cubic yards per 8-hour day. What is the rate of pour in feet per hour
Answers
The rate of pour in feet per hour is approximately 2.51 feet per hour.
First, we need to convert the dimensions to feet:
Length = 151 feet 4 inches = 151.33 feet
Height = 14 feet
Thickness = 16 inches = 1.33 feet
Next, we need to calculate the volume of the wall:
Volume = Length x Height x Thickness
Volume = 151.33 x 14 x 1.33
Volume = 2813.89 cubic feet
To convert cubic feet to cubic yards, we divide by 27:
Volume = 2813.89 / 27
Volume = 104.22 cubic yards
Given the daily placement rate of 375 cubic yards per 8-hour day, we can calculate the rate of pour in cubic yards per hour:
Rate of pour = 375 / 8
Rate of pour = 46.88 cubic yards per hour
Finally, we can convert the rate of pour to feet per hour by dividing by the cross-sectional area of the wall:
Cross-sectional area = Height x Thickness
Cross-sectional area = 14 x 1.33
Cross-sectional area = 18.62 square feet
Rate of pour in feet per hour = Rate of pour in cubic yards per hour / Cross-sectional area
Rate of pour in feet per hour = 46.88 / 18.62
Rate of pour in feet per hour ≈ 2.51 feet per hour

It ends up actually costing the patient $524.50. What is the percent of error in the bill? Round to the nearest tenths place
Answers
Answer:
8.5%
Step-by-step explanation:
The formula for Percentage error =
[|Measured value - Real value |/Real value] × 100
Measured value = Estimated value = $480.
Real value = $524.50
Percentage error =
[|480 - 524.50|/524.50] × 100
=[ |-44.5|/524.50] × 100
= [44.5/524.50] × 100
= 8.484270734%
≈ 8.5%
Therefore the percentage error in the bill = 8.5%

Average love of cats is not significantly different from average love of school, but increased love of cats is associated with increased love of school.
If there were zero correlation, the probability of increased love of cats being reliably associated with increased love of school on this 5-point scale would decrease.
How does the analysis result indicate the relationship between love of cats and love of school?The answer to question 1 is: The result of this analysis shows that, on this 5-point scale, the average love of cats is probably not significantly different from the average love of school, but increased love of cats is reliably associated with increased love of school.
How does a zero correlation affect the relationship between love of cats and love of school?The answer to question 2 is: If there were zero correlation between the love of cats and the love of school on this 5-point scale, the average love of cats is probably significantly different from the average love of school, and increased love of cats is probably not reliably associated with increased love of school compared to the observed correlation (R = 0.03) or a larger correlation between the two variables.
