I searched that in my math book dictionary and i found out that adjacent angles are two non-overlapping angles that share a vertex and a side
Answer:
1) Is more representative
Step-by-step explanation:
The problem with his selection is that maybe there are few students participating in certain sport and those students maybe do quite more excercise than the rest (or quite less). This will modify the results because the sample he selected is biased. This problem wont be solved by method 3 or 4, because he is still selecting students that may modify heavily the results with a high probability
This problem will also appear if he choose a sample by class. Maybe, in a class there are quite few students, and selecting from class will make those students appear quite more often than, lets say, a 7th grade student selected at random, therefore the selection is biased in this case as well.
If he has a list with all seventh grade students, each student is equallly likely to be selected and as a consequence, the the results wont be biased. Approach 1 is the best one.
If you would like to solve 24% of what number is 12, you can do this using the following steps:
24% of what number is 12
24% of x is 12
24% * x = 12
24/100 * x = 12 /*100/24
x = 12 * 100 / 24
x = 50
Result: 24% of 50 is 12.
If you would like to know which fraction (in simplest form) is equivalent to 0.42, you can find this using the following steps:
0.42 = 42/100 = 21/50
The correct result would be D. 21/50.
The answer is (20,0). We can determine the sum of two vector points by adding x1 to x2 and y1 to y2. This is like adding integers, the only difference is the answer is in vector form. In here, we have (x,y). x = 7+13 and y = 5+(-5). that is why we have the (20,0) as the answer.
