Answer:
y=44
Step-by-step explanation:
1/2y=22
y=22/(1/2)
y=(22/1)(2/1)
y=44/1
y=44
The problem does not say anything about how many of the marbles are yellow but if you put the first one back in the bag then it is an independent probability and each one would be the same individual probability. Since the problem doesn't say and I don't know if you have it somewhere else, I'll do it as an example.
Let's say there were 6 of the 10 marbles were yellow. So the probability of the first one is 6/10 and so is the second one 6/10. To find the total probability you multiply them together 6/10*6/10=36/100=9/25
Hope that helps. If you can tell me how many yellow there are I will show the work for the specific problem.
Answer:
I can only do mean and median
First, you have to write it in decreasing order
1, 4, 5, 6,7,8,9,9,9,11
Now, we seperate them
1, 4, 5, 6,7,8,9,9,9,11
the two middle numbers are 7 and 8 so the median is 7.5
upper quartile: 8,9,9,9,11
lower quartile: 1, 4, 5, 6, 7
To find the mean, we have to add all the numbers and divide it by the amount of numbers. There are 10 numbers and added togetehr they are 69 so divide 69 by 10 so 6.9 for the mean and 7.5 for median
