Option 2 would be biased. Asking people participating in a walkathon means you are asking people that are already volunteering. To get a non-biased sample, you have to be sure that you are including people that are not guaranteed to be volunteers; you don't have that in this situation.
Answer:
24 > 17 1/2 > 6.9 > 2 > 1.45 > - 1/4 > - 5.1
Step-by-step explanation:
Given the following temperature values :
2, 6.9, 17 1/2 , −5.1, 24, − 1/4 , and 1.45.
Ordering the values above from greatest to least ; (descending order)
Expressing all temperature values in the same format :
Let's make sure all values are in decimal to make comparison easier :
2.0
6.9
17 1/2 = 35/2 = 17.5
-5.1
24.0
-1/4 = - 0.25
1.45
We begin from the temperature value which is highest :
24 > 17.5 > 6.9 > 2.0 > 1.45 > - 0.25 > - 5.1
Hence ;
24 > 17 1/2 > 6.9 > 2 > 1.45 > - 1/4 > - 5.1
Answer:
(12 × 4) = 24 square feet
Step-by-step explanation:
The shaded triangle's area is found using the formula for the area of any triangle, A = 1/2 b*h. The base of the triangle is the longest side 12 ft. The height is 4 ft.
A = 1/2 *12*4 = 6*4 = 24 square feet
This is the solution though the expression is missing the 1/2.
(12 × 4) = 24 square feet
