The best way to solve this equation is to multiply the probability of them each getting a cotton sweater. The first fraction would be 1/2 because half of the sweaters are cotton at this point. The second one would be 6/13 because there are now six cotton sweaters out of the thirteen sweaters left. The third would be 5/12 because there are now five cotton sweaters out of the twelve sweaters left. The last one would be 4/11 because there are now four cotton sweaters out of the eleven sweaters left. you would then multiply 2 by 13 getting 26, then multiply 26 by 12 getting 312. Finally, multiply 312 by 11 getting 3,432, which would be your denominator. You would then multiply 6, 5, and 4 getting 120, your numerator. Getting your simplified answer 5/143.
Answer:
If the differences between <u>the group means is large relative to the amount of variability in the scores</u>, the group differences are probably significant. If, however, there is a lot of variability in the scores, then the difference between (or among) the group means will not seem so large, a non-significant difference.
So to summarize, it depends on the group. As there is no shown group, I can't determine what it would be.
I would have to say the best answer would be B
Answer:
5
Step-by-step explanation:
By the pythagorean theorem, x^2 = 13^2-12^2. 13^2-12^2 = 25, and the square root of 25 is 5
