First find the mean (sum divided by number of values)
4+5+8+10+15=42
42/5=8.4
Then find the difference between each of the numbers and the mean.
4.4, 3.4, 0.4, 1.6, 6.6
Then find the mean of those values.
4.4+3.4+0.4+1.6+6.6=16.4
16.4/5=3.28
Final answer: 3.28
First flip
We know the probability of head is 2/7
Since only 2 things can happen, and both cannot happen at once (mutually exclusive), we write
P(tail) = 1 - P(head) = 1 - 2/7 = 5/7
The probability of tail is 1 minus probability of head.
Second flip
You're still using the sam coin, and whatever you got on the first flip doesn't affect your chances of getting head... on the second flip, I mean. So,
2/7; 5/7; 2/7; 5/7
from top to bottom
Answer:
a)
, b) $101
Step-by-step explanation:
Hermes: 8 envelopes, $218
Apollo: 5 envelopes, $521
If x is the amount in each envelope, H is the amount Hemes has and A is the amount Apollo has, this would be a possible system of equations.

If Apollo and Hermes both had the same amount of total money, A and H could equal y

We want to find the amount in each envelope (x), so we can substitute y in the first equation for y in the second equation:

Subtract
from both sides

Subtract 218 from both sides

Divide both sides by 3

So there would have to be $101 in both envelopes for Apollo and Hermes to have the same amount of total money.
Answer:
Step-by-step explanation:
A. y= 5.50x+8
5.50 is your slope and 8 is your y-intercept
