Answer:
Aman's age = 20, Arun's age = 28
Step-by-step explanation:
Let = Aman's age
Let = Arun's age
- - - -
(Sum of their age is 56 after 4 years in the future)
(Ages are in the ratio 5:7)
Now, we can use substitution to find for Arun's age:
∴ Arun is
To find for Aman's age, we can use substitution:
∴ Aman is 20

Answer:
19.2
Step-by-step explanation:
The answer is c, 2.To find this, look on the graph for a point with the y value of -1. (2,-1) is the solution.
Answer: (1,5) (...midpoint..., ...negative reciprocal...)
Step-by-step explanation:
What is the line of reflection? It is the line across which the point is reflected. By definition of reflection, the distance of the preimage and the image from this line are the same. Since the distances are the same, they meet exactly halfway from each other. This means if you find the midpoint of the preimage and image you find a point on the line of reflection. But one point is not enough. Slope or another point is necessary. Slope is a lot easier to get.
Think about it. The line of reflection will always be perpendicular to the line connecting the preimage and image. Therefore its [line of reflection] slope will be the negative reciprocal of the slope of the preimage and image. Now you have slope and a point and thus a defined line of reflection

Answer:
Option d (quantitative data) is the correct choice.
Step-by-step explanation:
- Quantitative data seems to be a collection or kind of data which is concerned regarding quantitative information or methods. That indicates its value, as well as the condition, could be represented arithmetically.
- All evidence that can be quantified, checked, and suitable for statistical analysis categorizes as quantitative methods.
The remaining three options do not apply to the specified scenario. Therefore the description made will serve as an example of quantitative data.
