Answer:
12
Step-by-step explanation:
Hello there! I can help you! So there is one blue counter added to two green counters. To solve this problem, we can write and solve an equation. Set it up like this:
12 + 1x = 8 + 2x
We do this, because there are already some of each color in the bag. 1x makes one counter each and 2x is two counters for every blue counter in the bag. Let's solve it. Subtract 1x from each side. 1x - 1x cancels out. 2x - 1x is 1x or just simply x. That simplifies to 12 = 8 + x. Subtract 8 from each side to get the variable by itself. 8 - 8 cancels out. 12 - 8 is 4. That leaves 4 = x. Nothing else needs to be done. Let's plug the value in and see if it works. 1 * 4 is 4. 12 + 4 is 16. 2 * 4 is 8. 8 + 8 is 16. 16 = 16. There. x = 4. 4 blue counters and 8 green counters were added to the bag.
Answer:
After statistical analysis we find that the critical value with respect to a level of significance of 0.01 is greater, we deduce that if there is a difference in the number of rounds played per day in the week
Step-by-step explanation:
120+105+100+150+150=625/5=125= Expected frecuency
(observed - expected)^2/expected
Monday. 120 2
Tuesday. 105. 3.2
Wednesday. 100. 5
Thursday. 150. 5
Friday 150. 5
The total sum will give us the statistical chi-square test that is 20.2
according to the previous listing we look for the degrees of freedom:
5-1=4
Critical value = 3.747
After statistical analysis we find that the critical value with respect to a level of significance of 0.01 is greater, we deduce that if there is a difference in the number of rounds played per day in the week
