Q7. Data represented through arithmetic line graph help in understanding
Answer : Option D
Explaination / Solution:
An arithmetic line graph is also called time series graph. In this graph time (hour, day/date, week, month, year, etc.) is plotted along x-axis and the value of the variable (time series data) along y-axis. A line graph by joining these plotted points, thus, obtained is called arithmetic line graph (time series graph). It helps in understanding the trend, periodicity, etc. in a long term time series data.

Q9. Vectors can be added by
Answer : Option B
Explaination / Solution:
Vector addition is the operation of adding two or more vectors together into a vector sum. The so-called parallelogram law gives the rule for vector addition of two or more vectors. For two vectors, the vector sum is obtained by placing them head to tail and drawing the vector from the free tail to the free head.
