Waich of the following is a true statement about perpendicular lines?
A. Perpendicular lines intersect to form a 45° angle.
B. Perpendicular lines can also be parallel lines.
C. Perpendicular lines cannot be parallel to each other.
D. Perpendicular lines intersect in at least two points.
Answer:
C
Step-by-step explanation:
perpendicular lines intersect at a 90 degree angle, meaning it is not answer choice A.
B is incorrect because perpendicular lines intersect, so they can not be parallel.
C is correct because parallel lines never intersect, so perpendicular lines can never be parallel to each other.
D is incorrect because perpendicular lines only intersect at one point and create four consistent right angles.

(Q2) The set of line segments _____ meet the requirements to form a triangle.8 cm4 cm3 cm
To form a triangle, the set of line segments must satisfy the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Therefore, we need to check if the given line segments 8 cm, 4 cm, and 3 cm meet this requirement.
We can start by checking if the sum of the two smaller sides (3 cm and 4 cm) is greater than the largest side (8 cm). 3 cm + 4 cm = 7 cm, which is less than 8 cm. Therefore, these three line segments cannot form a triangle.
In general, for a set of line segments to form a triangle, the largest side must be smaller than the sum of the other two sides. In this case, the line segment of 8 cm is too long compared to the other two sides, which makes it impossible to form a triangle.
In conclusion, there are no line segments that meet the requirements to form a triangle with lengths of 8 cm, 4 cm, and 3 cm.

is y = 2 3 ex 4e−2x a solution of the differential equation y' 2y = 2ex?
No, y=23ex−4e−2x is not a solution of the differential equation y' + 2y = 2ex, as it does not satisfy the equation.
To check whether y = 23ex−4e−2x is a solution of the differential equation y' + 2y = 2ex, we need to verify that y satisfies the equation.
First, let's find y':
y' = (23)ex - (42)e-2x
Next, let's substitute y and y' into the differential equation:
y' + 2y = (23)ex - (42)e-2x + 2(23ex-4e-2x)
Simplifying this expression, we get:
y' + 2y = 6ex - 8e-2x + 2(3ex-2e-2x)
y' + 2y = 6ex - 8e-2x + 6ex-4e-2x
y' + 2y = 12ex - 12e-2x
So we can see that y = 23ex−4e−2x is not a solution of the differential equation y' + 2y = 2ex, since y does not satisfy the equation.

Answer:
Option (2)
Step-by-step explanation:
By the property of triangle,
If the sides of triangle are unequal, then the ratio of the measures of the angles will be equal to the ratio of their opposite sides.
Following this rule,
Angle opposite to the largest side will be biggest and angle opposite to the smallest side will be smallest.
Since, LJ > KL > JK
Therefore,
∠K > ∠J > ∠L
Option (2) will be the answer.
Explain how the sample you collect can affect your understanding of a population.
Use the word representative in your response.
The sample we collect plays a cruciThe sample we collect can significantly affect our understanding of a population,
especially when it comes to making generalizations or drawing conclusions about the entire population based on the sample data. The key aspect in this regard is whether the sample is representative of the population.
A representative sample is one that accurately reflects the characteristics, diversity, and distribution of the population from which it is drawn. When our sample is representative, we can have greater confidence in generalizing the findings from the sample to the larger population. However, if our sample is not representative, our understanding of the population may be biased or limited.
In the provided example, the given data represents different age groups and their reported time spent with friends per day. If we were to collect a sample from this population, it would be crucial to ensure that the sample includes individuals from each age group in proportion to their representation in the population. This would help ensure that our sample accurately reflects the age distribution of the population.
If our sample is not representative, it may lead to inaccurate conclusions. For instance, if we only surveyed individuals from the age group 55-64 and ignored the other age groups, our understanding of the population's time spent with friends would be limited to that specific age group. We wouldn't be able to generalize our findings to the entire population because we would have missed important variations in behavior across other age groups.
To improve the representativeness of our sample, we could use random sampling techniques, such as simple random sampling or stratified sampling, to ensure that individuals from all age groups are included in the sample. By doing so, we can enhance our understanding of the population as a whole and make more accurate inferences.
In conclusion, the sample we collect plays a crucial role in shaping our understanding of a population. A representative sample enables us to make valid generalizations and draw reliable conclusions about the entire population. It ensures that the characteristics and diversity of the population are properly reflected in the sample, allowing for more accurate insights and informed decision-making.al role in shaping our understanding of a population

if EG = 23 and EF = 12, then FG=
If EG = 23 and EF = 12 then FG is equal to the length of 11.
Given that EG = 23 and EF = 12.
We are required to find the length of line segment FG.
We assume that EG and EF both are parts on a line.
A line segment is basically bounded by two distinct points on a line. Or we can say that a line segment is part of the line that connects two points. A line has no endpoints and extends to infinite points in both the direction but a line segment has two fixed or definite endpoints.
If EG=23 and EF=12 then, EG=EF+FG
FG=EG-EF
FG=23-12
FG=11
Hence if EG = 23 and EF = 12 then FG is equal to the length of 11.

In interpreting effect size, what is the meaning of effect size at 0.3?
a. small effect size
b. medium effect size
c. large effect size
d. weak effect size
In interpreting effect size, the meaning of effect size at 0.3 is small effect size. So, the correct answer is A).
In interpreting effect size, an effect size of 0.3 is typically considered to be a small effect size. This means that there is a small but still measurable difference or relationship between two variables.
The interpretation of effect size can vary depending on the context and the discipline in which it is being used, but as a general rule, effect sizes of 0.2 or smaller are considered small, effect sizes of 0.5 are considered medium, and effect sizes of 0.8 or larger are considered large. Therefore, an effect size of 0.3 falls in the small effect size range. So, the correct option is A).

If the original price of a dress is £20 what would be its sale price?
25% off means the new price of the item is 75% of the originl price ( 100% - 25% = 75%)
Multiply the original price by 75%:
