The answer is it represents a sample statistic.
A sample is a small group of members selected from the population. A population is a larger collective group of people of all possible members. The characteristic of a sample is called a statistic.
1. Find angle Y. Since the interior angles of a triangle must add up to 180 deg., we have 180 - (98+24) = 58 deg.
Apply the Law of Sines to determine the lengths of sides r and t:
r 7.9 t
--------- = --------- = ---------
sin 98 sin 58 sin 24
Then r = (7.9 sin 98)/ (sin 58) = 9.22. This matches r in the 2nd choice. Determine t using the same method: t = 7.9sin 24 / sin 58.
Does your t value match that in the 2nd possible answer?
Let the length be 9x and the width = 8x
Perimeter = 2(l + w) = 2(9x + 8x) = 2(17x) = 34x = 68
x = 68/34 = 2
9x = 9(2) = 18 ft
8x = 8(2) = 16 ft
Therefore, dimensions are 18 ft by 16ft
If the circumference of a circle is 40 m, its area is 127.32395447352 m².
Answer:
18
Step-by-step explanation:
x + (x + 1) + (x + 2) = 57
x + x + 1 + x + 2 = 57
x + x + x + 1 + 2 = 57
3x + 3 = 57
3x = 57 - 3
3x = 54
x = 54/3
x = 18
