Answer
The median is 83
Step-by-step explanation:
You must put the scores in order to find median.
48, 58, 65, 71, 77, 80, 83, 88, 92, 92, 93, 96, 97
Then you find the number that is in the exact middle of the list.
In this case the median (middle number) is 83
A because inverse is the opposite order so instead of -3/1 or 5/1 it becomes 1/-3 and 1/5
3x2.7=8.1,,, im not sure this is what you were asking for but i hope it helps

Answer:

And we can use the following formula:

And replacing the info we got:

Step-by-step explanation:
We define two events for this case A and B. And we know the probability for each individual event given by the problem:


And we want to find the probability that A and B both occurs if A and B are independent events, who menas the following conditions:


And for this special case we want to find this probability:

And we can use the following formula:

And replacing the info we got:

A-2b=-10
b=-10-a.
Hope this is the answer
