Concept
- Sample size is the number of participants or observations included in a study. It is denoted by ‘n’
- Sample variance is a measure of the degree to which the numbers in a list are spread out. It is denoted by '
'
- Standard deviation is a measure of how dispersed the data is in relation to the mean. It is denoted by ‘s’

Answer:
Jill
Step-by-step explanation:
Since 250 is closer to 0 (which is the sea level) on the number line compared to 275, Jill is closer to sea level.
Step-by-step explanation:
- Length of rectangle = 7 less than the twice the breadth
- Perimeter = 40 cm
Let us say the breadth as b and length as l.
→ Length = 7 less than the twice the breadth
→ l = 2b - 7 ...(1)
Now, according to the question,
→ Perimeter of rectangle = 2(l + b)
→ 40 = 2(2b - 7 + b)
→ 40 = 2(3b - 7)
→ 40 = 6b - 14
→ 40 + 14 = 6b
→ 54 = 6b
→ 54 ÷ 6 = b
→ <u>9</u><u> m = Breadth</u>
Now, finding length.
→ l = 2b - 7
→ l = 2(9) - 7 m
→ l = 18 - 7 m
→ <u>Length = 1</u><u>1</u><u> m</u>
